Safety Warnings and Symbols There are a number of safety cautions in this book. We use a box and the word CAUTION to tell about things that could hurt you if you were to ignore the warning. { CAUTION: These mean there is something that could hurt you or other people. In the caution area, we tell you what the hazard is. Then we tell you what to do to help avoid or reduce the hazard. Please read these cautions. If you do not, you or others could be hurt. You will also find a circle with a slash through it in this book. This safety symbol means “Do Not,” “Do Not do this” or “Do Not let this happen.” iii[...]

Vehicle Damage Warnings Also, in this manual you will find these notices: Notice: These mean there is something that could damage your vehicle. A notice tells about something that can damage the vehicle. Many times, this damage would not be covered by your vehicle’s warranty, and it could be costly. But the notice will tell what to do to help avoid the damage. When you read other manuals, you might see CAUTION and NOTICE warnings in different colors or in different words. There are also warning labels on the vehicle. They use the same words, CAUTION or NOTICE. Vehicle Symbols The vehicle has components and labels that use symbols instead of text. Symbols are shown along with the text desc[...]

Front Seats Manual Seats { CAUTION: You can lose control of the vehicle if you try to adjust a manual driver’s seat while the vehicle is moving. The sudden movement could startle and confuse you, or make you push a pedal when you do not want to. Adjust the driver’s seat only when the vehicle is not moving. If your vehicle has a manual bucket or a split bench seat, you can adjust the seat forward or rearward with the bar located under the front of the seat cushion. Lift the bar to unlock the seat. Slide the seat to where you want it and release the bar. Try to move the seat with your body to be sure the seat is locked in place. 1-3[...]

Power Seats If your vehicle has power seats, the controls are located on the outboard side of the seats. • Raise or lower the front of the seat cushion by raising or lowering the front of the horizontal control. • Raise or lower the rear of the seat cushion by raising or lowering the rear of the horizontal control. • Raise or lower the entire seat cushion by raising or lowering the whole horizontal control. • Move the seat forward or rearward by moving the horizontal control forward or rearward. If your vehicle has power reclining seatbacks, the control is located rear of the power seat control on the outboard side of the seats. Adjust the angle of the seatback by pressing the vertic[...]

Heated Seats If your vehicle has this feature, the buttons are located on the front doors. The engine must be running for the heated seats to work. To heat the entire seat, press the horizontal button with the heated seat and seatback symbol. Press the button to cycle through the temperature settings of high, medium and low and to turn the heated seat off. Indicator lights will be lit to designate the level of heat selected: three for high, two for medium, and one for low. To heat only the seatback, press the vertical button with the heated seatback symbol. An indicator light on the seatback button will be lit to designate that only the seatback is being heated. Additional presses of the sea[...]

Reclining Seatbacks { CAUTION: If the seatback is not locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always push and pull on the seatback to be sure it is locked. To adjust the seatback, lift the manual lever located on the outboard side of the seat. Release the lever to lock the seatback in the desired position. Lift the lever again without pushing on the seatback and the seatback will go to an upright position. 1-6[...]

If your vehicle has power seats with a power recliner, see Power Seats on page 1-4 for further information on how to operate the reclining seatback feature. { CAUTION: Sitting in a reclined position when your vehicle is in motion can be dangerous. Even if you buckle up, your safety belts cannot do their job when you are reclined like this. The shoulder belt cannot do its job. In a crash, you could go into it, receiving neck or other injuries. The lap belt cannot do its job either. In a crash the belt could go up over your abdomen. The belt forces would be there, not at your pelvic bones. This could cause serious internal injuries. For proper protection when the vehicle is in motion, have the[...]

Head Restraints Adjust your head restraint so that the top of the restraint is closest to the top of your head. This position reduces the chance of a neck injury in a crash. Pull the head restraint up to raise it. Push the head restraint down to lower it. Your rear seats may have head restraints that can be adjusted up and down. Seatback Latches The front seatbacks fold forward to allow access to the rear of the cab. To fold the seatback forward, lift the lever located on the outboard side of the seat cushion. { CAUTION: If the seatback is not locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always push and pull on the seatback to [...]

Rear Seats Rear Seat Operation (Extended Cab) Folding the Rear Seat The rear seat in the extended cab can be folded up to provide more cargo space. To fold the seat up, do the following: 1. Push down on the front of the seat cushion while pulling down on the release strap which is located under the seat cushion. 2. Pull the seat cushion up until it latches with the seatback. 3. After latching the seat cushion up, pull forward on it to make sure it is locked. The seat can also be folded down for more seating space. To fold the seat down, do the following: 1. Push the seat cushion while pulling the release strap which is located under the seat cushion. Pull the seat cushion down until it latch[...]

Rear Seat Operation (Crew Cab) The second row seat is a 60/40 split seat. Either side of the rear seat may be flipped and folded for added cargo space. Make sure that nothing is under or in front of the seat and that the head restraints are completely lowered. To flip and fold the seat, do the following: 1. Pull up on the strap loop at the rear of the seat cushion. Then, pull the seat cushion up and flip it forward. 2. After folding the seat cushion fully forward, pull the seatback forward until it is flat. If the seatback cannot fold flat because it interferes with the cushion, try moving the front seat forward and/or bringing the front seat more upright. The lever at the base of the s[...]

To return the seat to the normal seating position, do the following: 1. Lift the seatback up and push it rearward all the way. { CAUTION: If the seatback is not locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always push and pull on the seatback to be sure it is locked. 2. Push and pull on the seatback to make sure it is locked into place. 3. Lower the seat cushion until it latches into position. Pull up on the cushion to make sure it is locked into place. { CAUTION: A safety belt that is improperly routed, not properly attached, or twisted will not provide the protection needed in a crash. The person wearing the belt could be ser[...]

Safety Belts Safety Belts: They Are for Everyone This part of the manual tells you how to use safety belts properly. It also tells you some things you should not do with safety belts. { CAUTION: Do not let anyone ride where he or she cannot wear a safety belt properly. If you are in a crash and you are not wearing a safety belt, your injuries can be much worse. You can hit things inside the vehicle or be ejected from it. You can be seriously injured or killed. In the same crash, you might not be, if you are buckled up. Always fasten your safety belt, and check that your passengers’ belts are fastened properly too. { CAUTION: It is extremely dangerous to ride in a cargo area, inside or outs[...]

You never know if you will be in a crash. If you do have a crash, you do not know if it will be a bad one. A few crashes are mild, and some crashes can be so serious that even buckled up, a person would not survive. But most crashes are in between. In many of them, people who buckle up can survive and sometimes walk away. Without belts they could have been badly hurt or killed. After more than 30 years of safety belts in vehicles, the facts are clear. In most crashes buckling up does matter...a lot! Why Safety Belts Work When you ride in or on anything, you go as fast as it goes. Take the simplest vehicle. Suppose it is just a seat on wheels. 1-13[...]

or the safety belts! With safety belts, you slow down as the vehicle does. You get more time to stop. You stop over more distance, and your strongest bones take the forces. That is why safety belts make such good sense. Questions and Answers About Safety Belts Q: Will I be trapped in the vehicle after an accident if I am wearing a safety belt? A: You could be — whether you are wearing a safety belt or not. But you can unbuckle a safety belt, even if you are upside down. And your chance of being conscious during and after an accident, so you can unbuckle and get out, is much greater if you are belted. Q: If my vehicle has airbags, why should I have to wear safety belts? A: Airbags are in ma[...]

Q: If I am a good driver, and I never drive far from home, why should I wear safety belts? A: You may be an excellent driver, but if you are in an accident — even one that is not your fault — you and your passengers can be hurt. Being a good driver does not protect you from things beyond your control, such as bad drivers. Most accidents occur within 25 miles (40 km) of home. And the greatest number of serious injuries and deaths occur at speeds of less than 40 mph (65 km/h). Safety belts are for everyone. How to Wear Safety Belts Properly This part is only for people of adult size. Be aware that there are special things to know about safety belts and children. And there are different rul[...]

4. Push the latch plate into the buckle until it clicks. Pull up on the latch plate to make sure it is secure. If the belt is not long enough, see Safety Belt Extender on page 1-30 . Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if you ever had to. 5. To make the lap part tight, pull up on the shoulder belt. The lap part of the belt should be worn low and snug on the hips, just touching the thighs. In a crash, this applies force to the strong pelvic bones. And you would be less likely to slide under the lap belt. If you slid under it, the belt would apply force at your abdomen. This could cause serious or even fatal injuries[...]

Q: What is wrong with this? A: The shoulder belt is too loose. It will not give nearly as much protection this way. { CAUTION: You can be seriously hurt if your shoulder belt is too loose. In a crash, you would move forward too much, which could increase injury. The shoulder belt should fit against your body. 1-19[...]

Q: What is wrong with this? A: The belt is buckled in the wrong place. { CAUTION: You can be seriously injured if your belt is buckled in the wrong place like this. In a crash, the belt would go up over your abdomen. The belt forces would be there, not at the pelvic bones. This could cause serious internal injuries. Always buckle your belt into the buckle nearest you. 1-20[...]

Q: What is wrong with this? A: The belt is over an armrest. { CAUTION: You can be seriously injured if your belt goes over an armrest like this. The belt would be much too high. In a crash, you can slide under the belt. The belt force would then be applied at the abdomen, not at the pelvic bones, and that could cause serious or fatal injuries. Be sure the belt goes under the armrests. 1-21[...]

Q: What is wrong with this? A: The shoulder belt is worn under the arm. It should be worn over the shoulder at all times. { CAUTION: You can be seriously injured if you wear the shoulder belt under your arm. In a crash, your body would move too far forward, which would increase the chance of head and neck injury. Also, the belt would apply too much force to the ribs, which are not as strong as shoulder bones. You could also severely injure internal organs like your liver or spleen. 1-22[...]

Q: What is wrong with this? A: The belt is twisted across the body. { CAUTION: You can be seriously injured by a twisted belt. In a crash, you would not have the full width of the belt to spread impact forces. If a belt is twisted, make it straight so it can work properly, or ask your dealer to fix it. 1-23[...]

To unlatch the belt, just push the button on the buckle. The belt should go back out of the way. Before you close the door, be sure the belt is out of the way. If you slam the door on it, you can damage both the belt and your vehicle. Safety Belt Use During Pregnancy Safety belts work for everyone, including pregnant women. Like all occupants, they are more likely to be seriously injured if they do not wear safety belts. A pregnant woman should wear a lap-shoulder belt, and the lap portion should be worn as low as possible, below the rounding, throughout the pregnancy. The best way to protect the fetus is to protect the mother. When a safety belt is worn properly, it is more likely that the [...]

Right Front Passenger Position To learn how to wear the right front passenger’s safety belt properly, see Driver Position on page 1-17 . The right front passenger’s safety belt works the same way as the driver’s safety belt — except for one thing. If you ever pull the shoulder portion of the belt out all the way, you will engage the child restraint locking feature which may turn off the passenger’s frontal airbag. If this happens unintentionally, just let the belt go back all the way and start again. Center Front Passenger Position Lap Belt If your vehicle has a front bench seat, someone can sit in the center position. When you sit in the center front seating position, you have a l[...]

To make the belt shorter, pull its free end as shown until the belt is snug. Buckle, position and release it the same way as the lap part of a lap-shoulder belt. If the belt is not long enough, see Safety Belt Extender on page 1-30 . Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if you ever had to. Rear Seat Passengers It is very important for rear seat passengers to buckle up! Accident statistics show that unbelted people in the rear seat are hurt more often in crashes than those who are wearing safety belts. Rear passengers who are not safety belted can be thrown out of the vehicle in a crash. And they can strike others in[...]

Lap-Shoulder Belt All rear seat positions have lap-shoulder belts. Here is how to wear one properly. 1. Pick up the latch plate and pull the belt across you. Do not let it get twisted. The shoulder belt may lock if you pull the belt across you very quickly. If this happens, let the belt go back slightly to unlock it. Then pull the belt across you more slowly. 2. Push the latch plate into the buckle until it clicks. Pull up on the latch plate to make sure it is secure. When the shoulder belt is pulled out all the way, it will lock. If it does, let it go back all the way and start again. If the belt is not long enough, see Safety Belt Extender on page 1-30 . Make sure the release button on the[...]

The lap part of the belt should be worn low and snug on the hips, just touching the thighs. In a crash, this applies force to the strong pelvic bones. And you would be less likely to slide under the lap belt. If you slid under it, the belt would apply force at your abdomen. This could cause serious or even fatal injuries. The shoulder belt should go over the shoulder and across the chest. These parts of the body are best able to take belt restraining forces. The safety belt locks if there is a sudden stop or a crash, or if you pull the belt very quickly out of the retractor. { CAUTION: You can be seriously hurt if your shoulder belt is too loose. In a crash, you would move forward too much, [...]

Rear Safety Belt Comfort Guides Rear seat comfort guides may provide added safety belt comfort for older children who have outgrown booster seats and for some adults. When installed on a shoulder belt, the comfort guide positions the belt away from the neck and head. There is one guide for each outside passenger in the rear seat. Here is how to install a comfort guide and use the safety belt: 1. Remove the guide from its storage clip on the interior body. 2. Place the guide over the belt and insert the two edges of the belt into the slots of the guide. 3. Be sure that the belt is not twisted and it lies flat. The guide must be on top of the belt. 1-29[...]

{ CAUTION: A safety belt that is not properly worn may not provide the protection needed in a crash. The person wearing the belt could be seriously injured. The shoulder belt should go over the shoulder and across the chest. These parts of the body are best able to take belt restraining forces. 4. Buckle, position, and release the safety belt as described in Rear Seat Passengers on page 1-26 . Make sure that the shoulder belt crosses the shoulder. To remove and store the comfort guides, squeeze the belt edges together so that you can take them out of the guides. Slide the guide onto the storage clip. Safety Belt Extender If the vehicle’s safety belt will fasten around you, you should use i[...]

Child Restraints Older Children Older children who have outgrown booster seats should wear the vehicle’s safety belts. Q: What is the proper way to wear safety belts? A: An older child should wear a lap-shoulder belt and get the additional restraint a shoulder belt can provide. The shoulder belt should not cross the face or neck. The lap belt should fit snugly below the hips, just touching the top of the thighs. It should never be worn over the abdomen, which could cause severe or even fatal internal injuries in a crash. Accident statistics show that children are safer if they are restrained in the rear seat. In a crash, children who are not buckled up can strike other people who are buck[...]

{ CAUTION: Never do this. Here two children are wearing the same belt. The belt can not properly spread the impact forces. In a crash, the two children can be crushed together and seriously injured. A belt must be used by only one person at a time. Q: What if a child is wearing a lap-shoulder belt, but the child is so small that the shoulder belt is very close to the child’s face or neck? A: If the child is sitting in a seat next to a window, move the child toward the center of the vehicle. Also see Rear Safety Belt Comfort Guides on page 1-29 . If the child is sitting in the center rear seat passenger position, move the child toward the safety belt buckle. In either case, be sure that the[...]

{ CAUTION: Never do this. Here a child is sitting in a seat that has a lap-shoulder belt, but the shoulder part is behind the child. If the child wears the belt in this way, in a crash the child might slide under the belt. The belt’s force would then be applied right on the child’s abdomen. That could cause serious or fatal injuries. Wherever the child sits, the lap portion of the belt should be worn low and snug on the hips, just touching the child’s thighs. This applies belt force to the child’s pelvic bones in a crash. Infants and Young Children Everyone in a vehicle needs protection! This includes infants and all other children. Neither the distance traveled nor the age and size [...]

{ CAUTION: People should never hold a baby in their arms while riding in a vehicle. A baby does not weigh much — until a crash. During a crash a baby will become so heavy it is not possible to hold it. For example, in a crash at only 25 mph (40 km/h), a 12 lb (5.5 kg) baby will suddenly become a 240 lb (110 kg) force on a person’s arms. A baby should be secured in an appropriate restraint. 1-34[...]

{ CAUTION: Children who are up against, or very close to, any airbag when it inflates can be seriously injured or killed. Airbags plus lap-shoulder belts offer protection for adults and older children, but not for young children and infants. Neither the vehicle’s safety belt system nor its airbag system is designed for them. Young children and infants need the protection that a child restraint system can provide. 1-35[...]

Q: What are the different types of add-on child restraints? A: Add-on child restraints, which are purchased by the vehicle’s owner, are available in four basic types. Selection of a particular restraint should take into consideration not only the child’s weight, height and age but also whether or not the restraint will be compatible with the motor vehicle in which it will be used. For most basic types of child restraints, there are many different models available. When purchasing a child restraint, be sure it is designed to be used in a motor vehicle. If it is, the restraint will have a label saying that it meets federal motor vehicle safety standards. The restraint manufacturer’s inst[...]

{ CAUTION: The body structure of a young child is quite unlike that of an adult or older child, for whom the safety belts are designed. A young child’s hip bones are still so small that the vehicle’s regular safety belt may not remain low on the hip bones, as it should. Instead, it may settle up around the child’s abdomen. In a crash, the belt would apply force on a body area that is unprotected by any bony structure. This alone could cause serious or fatal injuries. Young children always should be secured in appropriate child restraints. Child Restraint Systems An infant car bed (A), a special bed made for use in a motor vehicle, is an infant restraint system designed to restrain or p[...]

A rear-facing infant seat (B) provides restraint with the seating surface against the back of the infant. The harness system holds the infant in place and, in a crash, acts to keep the infant positioned in the restraint. A forward-facing child seat (C-E) provides restraint for the child’s body with the harness and also sometimes with surfaces such as T-shaped or shelf-like shields. 1-38[...]

A booster seat (F-G) is a child restraint designed to improve the fit of the vehicle’s safety belt system. Some booster seats have a shoulder belt positioner, and some high-back booster seats have a five-point harness. A booster seat can also help a child to see out the window. Q: How Should I Use a Child Restraint? A: A child restraint system is any device designed for use in a motor vehicle to restrain, seat, or position children. A built-in child restraint system is a permanent part of the motor vehicle. An add-on child restraint system is a portable one, which is purchased by the vehicle’s owner. To help reduce injuries, an add-on child restraint must be secured in the vehicle. Wit[...]

Securing an Add-on Child Restraint in the Vehicle { CAUTION: A child can be seriously injured or killed in a crash if the child restraint is not properly secured in the vehicle. Make sure the child restraint is properly installed in the vehicle using the vehicle’s safety belt or LATCH system, following the instructions that came with that restraint, and also the instructions in this manual. To help reduce the chance of injury, the child restraint must be secured in the vehicle. Child restraint systems must be secured in vehicle seats by lap belts or the lap belt portion of a lap-shoulder belt, or by the LATCH system. See Lower Anchors and Tethers for Children (LATCH) on page 1-44 for more [...]

Securing the Child Within the Child Restraint There are several systems for securing the child within the child restraint. One system, the three-point harness, has straps that come down over each of the infant’s shoulders and buckle together at the crotch. The five-point harness system has two shoulder straps, two hip straps, and a crotch strap. A shield may take the place of hip straps. A T-shaped shield has shoulder straps that are attached to a flat pad which rests low against the child’s body. A shelf- or armrest-type shield has straps that are attached to a wide, shelf-like shield that swings up or to the side. { CAUTION: A child can be seriously injured or killed in a crash if th[...]

Where to Put the Restraint Accident statistics show that children are safer if they are restrained in the rear rather than the front seat. We recommend that child restraints be secured in a rear seat including an infant riding in a rear-facing infant seat, a child riding in a forward-facing child seat and an older child riding in a booster seat. Your vehicle may have a label on your sun visor that says, “Never put a rear-facing child seat in the front.” This is because the risk to the rear-facing child is so great, if the airbag deploys. Never put a child in a rear-facing child restraint in the right front passenger seat unless your vehicle has the passenger sensing system or an airbag o[...]

CAUTION: (Continued) If you need to secure a forward-facing child restraint in the right front seat, always move the front passenger seat as far back as it will go. It is better to secure the child restraint in a rear seat. { CAUTION: A child in a child restraint in the center front seat can be badly injured or killed by the right front passenger’s airbag if it inflates. Never secure a child restraint in the center front seat. It is always better to secure a child restraint in the rear seat. Do not use child restraints in the center front seat position. The restraints will not work properly. There is limited space in the rear seating area of an extended cab model. If you want to secure a [...]

Lower Anchors and Tethers for Children (LATCH) Your vehicle has the LATCH system. The LATCH system holds a child restraint during driving or in a crash. This system is designed to make installation of a child restraint easier. The LATCH system uses anchors in the vehicle and attachments on the child restraint that are made for use with the LATCH system Make sure that a LATCH-compatible child restraint is properly installed using the anchors, or use the vehicle’s safety belts to secure the restraint, following the instructions that came with that restraint, and also the instructions in this manual. When installing a child restraint with a top tether, you must also use either the lower ancho[...]

Top Tether Anchor A top tether (A, C) anchors the top of the child restraint to the vehicle. A top tether anchor is built into the vehicle. The top tether attachment (B) on the child restraint connects to the top tether anchor in the vehicle in order to reduce the forward movement and rotation of the child restraint during driving or in a crash. Your child restraint may have a single tether (A) or a dual tether (C). Either will have a single attachment (B) to secure the top tether to the anchor. Some top tether-equipped child restraints are designed for use with or without the top tether being attached. Others require the top tether always to be attached. In Canada, the law requires that for[...]

For crew cab models, the rear passenger side and center seating positions have exposed metal lower anchors located in the crease between the seatback and the seat cushion. For extended cab models, the rear outboard seating positions have exposed metal lower anchors located in the crease between the seatback and the seat cushion. For regular and crew cab models, there is an anchor symbol on the trim covers to assist you in locating the top tether anchors. For regular cab models with a bench seat, the top tether anchors are located under trim covers on the back panel behind the center and passenger seats. Do not install a child restraint in the center seat position. See Securing a Child Restra[...]

For extended cab models, the top tether anchors are located near the top of the seatback for each rear seating position. In addition to the top tether anchors, each seating position has a fabric loop at the top of the seatback that you will use to route the top tether through. Be sure to use an anchor located on the same side of the vehicle as the seating position where the child restraint will be placed. For crew cab models, there are covered top tether anchors for each seating position located on the back panel of your vehicle, behind the rear seat. Remove the trim covers to access the anchors. Do not secure a child restraint in the front passenger’s position if your vehicle has rear sea[...]

Accident statistics show that children are safer if they are restrained in the rear rather than the front seat. See Where to Put the Restraint on page 1-42 for additional information. Securing a Child Restraint Designed for the LATCH System { CAUTION: If a LATCH-type child restraint is not attached to anchors, the restraint will not be able to protect the child correctly. In a crash, the child could be seriously injured or killed. Make sure that a LATCH-type child restraint is properly installed using the anchors, or use the vehicle’s safety belts to secure the restraint, following the instructions that came with that restraint, and also the instructions in this manual. { CAUTION: Each top[...]

Never put a rear facing child restraint in the right front passenger’s seat unless the airbag is off. Here is why: { CAUTION: A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s airbag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating airbag. Be sure the airbag is off before using a rear-facing child restraint in the right front seat position. If you secure a forward-facing child restraint in the right front seat, always move the right front passenger seat as far back as it will go. A rear seat is a safer place to secure a forward facing child restraint. See Where to Put the [...]

If your vehicle has a rear seat, there is no top tether anchor at the right front seating position. Do not secure a child seat in this position if a national or local law requires that the top tether be anchored or if the instructions that come with the child restraint say that the top tether must be anchored. See Lower Anchors and Tethers for Children (LATCH) on page 1-44 if the child restraint has a top tether. You will be using the lap-shoulder belt to secure the child restraint in this position.

Securing a Child Restraint in the Right Front Seat Position (Regular and Extended Cab) (With Passenger Sensing System) Your vehicle has a right front passenger airbag. A rear seat is a safer place to secure a forward-facing child restraint. See Where to Put the Restraint on page 1-42 . If your rearview mirror has one of the indicators pictured in the following illustrations, your vehicle has a passenger sensing system. The passenger sensing system is designed to turn off the right front passenger’s frontal airbag when an infant in a rear-facing infant seat or a small child in a forward-facing child restraint or booster seat is detected. See Passenger Sensing System on page 1-80 and Passeng[...]

Your vehicle may have a label on your sun visor that says, “Never put a rear-facing child seat in the front.” This is because the risk to the rear-facing child is so great, if the airbag deploys. { CAUTION: A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s airbag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating airbag. Even though the passenger sensing system is designed to turn off the passenger’s frontal airbag if the system detects a rear-facing child restraint, no system is fail-safe, and no one can guarantee that an airbag will not deploy under some unusual circum[...]

Airbag System Your vehicle has an airbag for the driver and an airbag for the right front passenger. Frontal airbags are designed to help reduce the risk of injury from the force of an inflating frontal airbag. But these airbags must inflate very quickly to do their job and comply with federal regulations. Here are the most important things to know about the airbag system: { CAUTION: You can be severely injured or killed in a crash if you are not wearing your safety belt — even if you have airbags. Wearing your safety belt during a crash helps reduce your chance of hitting things inside the vehicle or being ejected from it. Airbags are “supplemental restraints” to the safety belts. A[...]

{ CAUTION: Anyone who is up against, or very close to, any airbag when it inflates can be seriously injured or killed. Airbags plus lap-shoulder belts offer the best protection for adults, but not for young children and infants. Neither the vehicle’s safety belt system nor its airbag system is designed for them. Young children and infants need the protection that a child restraint system can provide. Always secure children properly in your vehicle. To read how, see Older Children on page 1-31 and Infants and Young Children on page 1-33 . There is an airbag readiness light on the instrument panel cluster, which shows the airbag symbol. The system checks the airbag electrical system for mal[...]

The right front passenger’s airbag is in the instrument panel on the passenger’s side. { CAUTION: If something is between an occupant and an airbag, the bag might not inflate properly or it might force the object into that person causing severe injury or even death. The path of an inflating airbag must be kept clear. Do not put anything between an occupant and an airbag, and do not attach or put anything on the steering wheel hub or on or near any other airbag covering. 1-72[...]

When Should an Airbag Inflate? The driver’s and right front passenger’s frontal airbags are designed to inflate in moderate to severe frontal or near-frontal crashes. But they are designed to inflate only if the impact exceeds a predetermined deployment threshold. Deployment thresholds take into account a variety of desired deployment and non-deployment events and are used to predict how severe a crash is likely to be in time for the airbags to inflate and help restrain the occupants. Whether your frontal airbags will or should deploy is not based on how fast your vehicle is traveling. It depends largely on what you hit, the direction of the impact and how quickly your vehicle slows [...]

Single Stage vs. Dual Stage Airbags Depending on the weight of your vehicle you will have either “Single Stage Airbags” or “Dual Stage Airbags”. Vehicles that have a passenger sensing system also have dual stage airbags. If the rearview mirror in your vehicle has a passenger airbag status indicator printed on it, your vehicle has the passenger sensing system and therefore, it has dual stage airbags. If the rearview mirror in your vehicle does not have a passenger airbag status indicator printed on it, then your vehicle does not have the passenger sensing system and it has single stage airbags. See Passenger Airbag Status Indicator on page 3-36 or Passenger Sensing System on page 1-80[...]

Single Stage Airbags If your vehicle has frontal airbags with single stage deployment and your vehicle goes straight into a wall that does not move or deform, the threshold level is about 13 to 16 mph (20 to 25 km/h). (The threshold level can vary, however, with specific vehicle design, so that it can be somewhat above or below this range.) What Makes an Airbag Inflate? In an impact of suff icient severity, the airbag sensing system detects that the vehicle is in a crash. The sensing system triggers a release of gas from the inflator, which inflates the airbag. The inflator, airbag, and related hardware are all part of the airbag modules inside the steering wheel and in the instrument p[...]

What Will You See After an Airbag Inflates? After an airbag inflates, it quickly deflates, so quickly that some people may not even realize the airbag inflated. Some components of the airbag module — the steering wheel hub for the driver’s airbag or the instrument panel for the right front passenger’s bag — may be hot for a short time. The parts of the bag that come into contact with you may be warm, but not too hot to touch. There will be some smoke and dust coming from the vents in the deflated airbags. Airbag inflation does not prevent the driver from seeing out of the windshield or being able to steer the vehicle, nor does it stop people from leaving the vehicle. { CAUTION:[...]

Airbag Of f Switch If your instrument panel has one of the switches pictured in the following illustrations your vehicle has an airbag off switch that you can use to turn of f the right front passenger’s airbag. This switch should only be turned to the off position if the person in the right front passenger’s position is a member of a passenger risk group identified by the national government as follows: Infant. An infant (less than 1 year old) must ride in the front seat because: • my vehicle has no rear seat; • my vehicle has a rear seat too small to accommodate a rear-facing infant seat; or • the infant has a medical condition which, according to the infant’s physician, makes[...]

Medical Condition. A passenger has a medical condition which, according to his or her physician: • causes the passenger airbag to pose a special risk for the passenger; and • makes the potential harm from the passenger airbag in a crash greater than the potential harm from turning off the airbag and allowing the passenger, even if belted, to hit the dashboard or windshield in a crash. { CAUTION: If the right front passenger’s airbag is turned off for a person who is not in a risk group identified by the national government, that person will not have the extra protection of an airbag. In a crash, the airbag will not be able to inflate and help protect the person sitting there. Do not [...]

The airbag off light will come on to let you know that the right front passenger’s airbag is off. The light will stay on to remind you that the airbag is off. The right front passenger’s airbag will remain off until you turn it back on. { CAUTION: If the airbag readiness light ever comes on when you have turned off the airbag, it means that something may be wrong with the airbag system. The right front passenger’s airbag could inflate even though the switch is off. If your vehicle is a regular cab pickup or an extended cab pickup and this ever happens, do not let anyone whom the national government has identified as a member of a passenger airbag risk group sit in the right front pas[...]

Passenger Sensing System If your rearview mirror has one of the indicators pictured in the following illustrations, your vehicle has a passenger sensing system. The indicator will be visible when you turn your ignition key to RUN or START. The words ON and OFF or the symbol for on and off, will be visible on the rearview mirror during the system check. When the system check is complete, either the word ON or the word OFF, or the symbol for on or the symbol for off will be visible. See Passenger Airbag Status Indicator on page 3-36 . If your rearview mirror does not have either of the indicators pictured below, then your vehicle does not have the passenger sensing system. The passenger sensin[...]

Accident statistics show that children are safer if they are restrained in the rear rather than the front seat. General Motors recommends that child restraints be secured in a rear seat, including an infant riding in a rear-facing infant seat, a child riding in a forward-facing child seat and an older child riding in a booster seat. Never put a child in a rear-facing child restraint in the right front passenger seat unless the passenger airbag status indicator shows off. Never put a rear-facing child restraint in the right front passenger seat unless the airbag is off. Your vehicle may have a label on your sun visor that says, “Never put a rear-facing child seat in the front.” This is be[...]

Never put a rear facing child restraint in the right front passenger seat unless the airbag is off. Here is why: { CAUTION: A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s airbag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating airbag. Be sure the airbag is off before using a rear-facing child restraint in the right front seat position.

If a person of adult-size is sitting in the right front passenger’s seat, but the off indicator is lit, it could be because that person is not sitting properly in the seat. If this happens, turn the vehicle off and ask the person to place the seatback in the fully upright position, then sit upright in the seat, centered on the seat cushion, with the person’s legs comfortably extended. Restart the vehicle and have the person remain in this position for about two minutes. This will allow the system to detect that person and then enable the passenger’s airbag. 1-84[...]

{ CAUTION: If the airbag readiness light in the instrument panel cluster ever comes on and stays on, it means that something may be wrong with the airbag system. If this ever happens, have the vehicle serviced promptly, because an adult-size person sitting in the right front passenger’s seat may not have the protection of the frontal airbag. See Airbag Readiness Light on page 3-33 for more on this, including important safety information. Aftermarket equipment, such as seat covers, can affect how well the passenger sensing system operates. You may want to consider not using seat covers or other aftermarket equipment if your vehicle has the passenger sensing system. See Adding Equipment to Y[...]

Servicing Your Airbag-Equipped Vehicle Airbags affect how your vehicle should be serviced. There are parts of the airbag system in several places around your vehicle. You do not want the system to inflate while someone is working on your vehicle. Your dealer and the service manual have information about servicing your vehicle and the airbag system. To purchase a service manual, see Service Publications Ordering Information on page 7-14 . { CAUTION: For up to 10 seconds after the ignition key is turned off and the battery is disconnected, an airbag can still inflate during improper service. You can be injured if you are close to an airbag when it inflates. Avoid yellow connectors. They are[...]

Q: What if I added a snow plow? Will it keep the airbags from working properly? A: We have designed our airbag systems to work properly under a wide range of conditions, including snow plowing with vehicles equipped with the optional Snow Plow Prep Package (RPO VYU). But do not change or defeat the snow plow’s “tripping mechanism.” If you do, it can damage your snow plow and your vehicle, and it may cause an airbag inflation. Q: Because I have a disability, I have to get my vehicle modified. How can I find out whether this will affect my advanced airbag system? A: Changing or moving any parts of the front seats, safety belts, the airbag sensing and diagnostic module (located under t[...]

Replacing Restraint System Parts After a Crash { CAUTION: A crash can damage the restraint systems in your vehicle. A damaged restraint system may not properly protect the person using it, resulting in serious injury or even death in a crash. To help make sure your restraint systems are working properly after a crash, have them inspected and any necessary replacements made as soon as possible. If you have had a crash, do you need new belts or LATCH system parts? After a very minor collision, nothing may be necessary. But if the belts were stretched, as they would be if worn during a more severe crash, then you need new parts. If the LATCH system was being used during a more severe crash, you[...]

By doing this, the vehicle shifts down to the next gear and has more power. DRIVE (D) can be used when towing a trailer, carrying a heavy load, driving on steep hills, or for off-road driving. You may want to shift the transmission to THIRD (3) or, if necessary, a lower gear selection if the transmission shifts too often. If your vehicle has the Allison Transmission ® , it will shift into first range when DRIVE (D) is select[...]

SECOND (2): This position gives you more power but lower fuel economy. You can use SECOND (2) on hills. It can help control your speed as you go down steep mountain roads, but then you would also want to use your brakes off and on. If you manually select SECOND (2) in an automatic transmission, the transmission will start in second gear. You may use this feature for reducing the speed of the rear wheels when you are trying to start your vehicle from a stop on slippery road surfaces. FIRST (1): This position gives you even more power (but lower fuel economy) than SECOND (2). You can use it on very steep hills, or in deep snow or mud. If the shift lever is put in FIRST (1) while the vehicle is[...]

Driving with this light displayed could drain your battery. If you must drive a short distance with this light displayed, it helps to turn off all your accessories, such as the radio and the air conditioner. Voltmeter Gage When your engine is not running, but the ignition is in RUN, this gage shows your bat[...]

Readings in the low warning zone may occur when a large number of electrical accessories are operating in the vehicle and the engine is left at an idle for an extended period. This condition is normal since the charging system is not able to provide full power at engine idle. As engine speeds are increased, this condition should correct itself as higher engine speeds allow the charging system to create maximum power. You can only drive for a short time with the reading in either warning zone. If you must drive, turn off all unnecessary accessories. Readings in either warning zone indicate a possible problem in the electrical system. Have the vehicle serviced as soon as possible. Up-Shift Lig[...]

Brake System Warning Light With the ignition on, the brake system warning light will flash when you set the parking brake. The light will flash if the parking brake doesn’t release fully. If you try to drive with the parking brake engaged, a chime will sound when the vehicle speed is greater than 3 mph (5 km/h). Your vehicle’s hydraulic brake system is divided into two parts. If one part isn’t working, the other part can still work and stop you. For good braking, though, you need both parts working well. If the warning light comes on and a chime sounds there could be a brake problem. Have your brake system inspected right away. This light should come on briefly when you turn the ign[...]

Anti-Lock Brake System Warning Light With the anti-lock brake system, this light will come on when you start your engine and may stay on for several seconds. That’s normal. If the light doesn’t come on then, have it fixed so it will be ready to warn you if there is a problem. If the light stays on, or comes on when you’re driving, your vehicle needs service. You will also hear a chime sound when the light is on steady. If the regular brake system warning light isn’t on, you still have brakes, but you don’t have anti-lock brakes. If the regular brake system warning light is also on you don’t have anti-lock brakes and there’s a problem with your regular brakes. In addition to bo[...]

Engine Coolant Temperature Gage This gage shows the engine coolant temperature. It also provides an indicator of how hard your vehicle is working. During a majority of the operation, the gage will read 210°F (100°C) or less. If you are pulling a load or going up hills, it is normal for the temperature to fluctuate and approach the 250°F (122°C) mark. If the gage reaches the 260°F (125°C) mark, it indicates that the cooling system is working beyond its capacity. See Engine Overheating on page 5-37 . Transmission Temperature Gage Your vehicle may be equipped with a transmission temperature gage. When your ignition is on, the gage shows the temperature of the transmission fluid. The nor[...]

Radio Reception You may experience frequency interference and static during normal radio reception if items such as cellphone chargers, vehicle convenience accessories, and external electronic devices are plugged into the accessory power outlet. If there is interference or static, unplug the item from the accessory power outlet. AM The range for most AM stations is greater than for FM, especially at night. The longer range can cause station frequencies to interfere with each other. For better radio reception, most AM radio stations will boost the power levels during the day, and then reduce these levels during the night. Static can also occur when things like storms and power lines interfere[...]

If there is a reduction in sound quality, try a known good cassette to see if the tape or the tape player is at fault.

Your Driving, the Road, and Your Vehicle Defensive Driving The best advice anyone can give about driving is: Drive defensively. Please start with a very important safety device in your vehicle: Buckle up. See Safety Belts: They Are for Everyone on page 1-12 . { CAUTION: Defensive driving really means “Be ready for anything.” On city streets, rural roads, or expressways, it means “Always expect the unexpected.” Assume that pedestrians or other drivers are going to be careless and make mistakes. Anticipate what they might do and be ready. Rear-end collisions are about the most preventable of accidents. Yet they are common. Allow enough following distance. Defensive driving requires tha[...]

Drunken Driving Death and injury associated with drinking and driving is a national tragedy. It is the number one contributor to the highway death toll, claiming thousands of victims every year. Alcohol affects four things that anyone needs to drive a vehicle: • Judgment • Muscular Coordination • Vision • Attentiveness Police records show that almost half of all motor vehicle-related deaths involve alcohol. In most cases, these deaths are the result of someone who was drinking and driving. In recent years, more than 16,000 annual motor vehicle-related deaths have been associated with the use of alcohol, with more than 300,000 people injured. Many adults — by some estimates, nearly [...]

According to the American Medical Association, a 180 lb (82 kg) person who drinks three 12 ounce (355 ml) bottles of beer in an hour will end up with a BAC of about 0.06 percent. The person would reach the same BAC by drinking three 4 ounce (120 ml) glasses of wine or three mixed drinks if each had 1-1/2 ounces (45 ml) of liquors like whiskey, gin, or vodka. It is the amount of alcohol that counts. For example, if the same person drank three double martinis (3 ounces or 90 ml of liquor each) within an hour, the person’s BAC would be close to 0.12 percent. A person who consumes food just before or during drinking will have a somewhat lower BAC level. There is a gender difference, too. Women[...]

But the ability to drive is affected well below a BAC of 0.10 percent. Research shows that the driving skills of many people are impaired at a BAC approaching 0.05 percent, and that the effects are worse at night. All drivers are impaired at BAC levels above 0.05 percent. Statistics show that the chance of being in a collision increases sharply for drivers who have a BAC of 0.05 percent or above. A driver with a BAC level of 0.06 percent has doubled his or her chance of having a collision. At a BAC level of 0.10 percent, the chance of this driver having a collision is 12 times greater; at a level of 0.15 percent, the chance is 25 times greater! The body takes about an hour to rid itself of t[...]

Control of a Vehicle You have three systems that make your vehicle go where you want it to go. They are the brakes, the steering, and the accelerator. All three systems have to do their work at the places where the tires meet the road. Sometimes, as when you are driving on snow or ice, it is easy to ask more of those control systems than the tires and road can provide. That means you can lose control of your vehicle. See Traction Assist System (TAS) on page 4-9 . Adding non-GM accessories can affect your vehicle’s performance. See Accessories and Modifications on page 5-4 . Braking See Brake System Warning Light on page 3-41 . Braking action involves perception time and reaction time. Fir[...]

Avoid needless heavy braking. Some people drive in spurts — heavy acceleration followed by heavy braking — rather than keeping pace with traff ic. This is a mistake. Your brakes may not have time to cool between hard stops. Your brakes will wear out much faster if you do a lot of heavy braking. If you keep pace with the traff ic and allow realistic following distances, you will eliminate a lot of unnecessary braking. That means better braking and longer brake life. If your engine ever stops while you are driving, brake normally but do not pump your brakes. If you do, the pedal may get harder to push down. If your engine stops, you will still have some power brake assist. But you will use[...]

Let us say the road is wet and you are driving safely. Suddenly, an animal jumps out in front of you. You slam on the brakes and continue braking. Here is what happens with ABS: A computer senses that wheels are slowing down. If one of the wheels is about to stop rolling, the computer will separately work the brakes at each front wheel and at both rear wheels. The anti-lock system can change the brake pressure faster than any driver could. The computer is programmed to make the most of available tire and road conditions. This can help you steer around the obstacle while braking hard. As you brake, your computer keeps receiving updates on wheel speed and controls braking pressure accordingly.[...]

Remember: Anti-lock does not change the time you need to get your foot up to the brake pedal or always decrease stopping distance. If you get too close to the vehicle in front of you, you will not have time to apply your brakes if that vehicle suddenly slows or stops. Always leave enough room up ahead to stop, even though you have anti-lock brakes. Using Anti-Lock Do not pump the brakes. Just hold the brake pedal down firmly and let anti-lock work for you. You may feel the brakes vibrate, or you may notice some noise, but this is normal. Braking in Emergencies With anti-lock brakes, you can steer and brake at the same time. In many emergencies, steering can help you more than even the very [...]

The traction off light will come on under the following conditions: • The Traction Assist System is turned off, either by pressing the TAS on/off button, located on the instrument panel, or by turning off the automatic engagement feature of the TAS. • The transmission is in FIRST (1); TAS will not operate in this gear. This is normal. • The vehicle is driven on an extremely rough road. When the vehicle leaves the rough surface, slows down or stops, the light will go off and TAS will turn on again. This is normal. • A Traction Assist System, Anti-Lock Brake System or engine-related problem has been detected and the vehicle needs service. • If the vehicle has been driven with the TAS[...]

Manual Selectable Ride The main function of this system is to provide superior ride comfort while trailering or fully loaded, as well as for unloaded driving. This system also helps to provide: • Improved trailering stability • Improved handling response when trailering or fully loaded This button is located on the center of the instrument panel near the radio. Press it to activate the selectable ride setting as desired. An indicator light near the button will illuminate whenever the system is active. It is recommended to use this system as follows: • For optimum ride comfort in an unloaded vehicle the button should be out. The indicator light will not be lit. This button position indi[...]

FIRM (Loaded): Press the button to activate this setting, the indicator light will be lit. Use this setting to minimize trailer inputs to the vehicle or when the vehicle is fully loaded. This setting is also appropriate for off-road driving. You can select a setting at any time based on road and trailering conditions to provide the best ride and handling. Select a new setting whenever driving conditions change. Locking Rear Axle If your vehicle has this feature, your locking rear axle can give you additional traction on snow, mud, ice, sand or gravel. It works like a standard axle most of the time, but when one of the rear wheels has no traction and the other does, this feature will allow th[...]

Suppose you are steering through a sharp curve. Then you suddenly accelerate. Both control systems — steering and acceleration — have to do their work where the tires meet the road. Adding the sudden acceleration can demand too much of those places. You can lose control. See Traction Assist System (TAS) on page 4-9 . What should you do if this ever happens? Ease up on the accelerator pedal, steer the vehicle the way you want it to go, and slow down. Speed limit signs near curves warn that you should adjust your speed. Of course, the posted speeds are based on good weather and road conditions. Under less favorable conditions you will want to go slower. If you need to reduce your speed as [...]

An emergency like this requires close attention and a quick decision. If you are holding the steering wheel at the recommended 9 and 3 o’clock positions, you can turn it a full 180 degrees very quickly without removing either hand. But you have to act fast, steer quickly, and just as quickly straighten the wheel once you have avoided the object. The fact that such emergency situations are always possible is a good reason to practice defensive driving at all times and wear safety belts properly. Of f-Road Recovery You may find that your right wheels have dropped off the edge of a road onto the shoulder while you are driving. If the level of the shoulder is only slightly below the pavement,[...]

Passing The driver of a vehicle about to pass another on a two-lane highway waits for just the right moment, accelerates, moves around the vehicle ahead, then goes back into the right lane again. A simple maneuver? Not necessarily! Passing another vehicle on a two-lane highway is a potentially dangerous move, since the passing vehicle occupies the same lane as oncoming traff ic for several seconds. A miscalculation, an error in judgment, or a brief surrender to frustration or anger can suddenly put the passing driver face to face with the worst of all traff ic accidents — the head-on collision. So here are some tips for passing: • Drive ahead. Look down the road, to the sides and to cros[...]

• Check your mirrors, glance over your shoulder and start your left lane change signal before moving out of the right lane to pass. When you are far enough ahead of the passed vehicle to see its front in your inside mirror, activate your right lane change signal and move back into the right lane. Remember that if your passenger side outside mirror is convex, the vehicle you just passed may seem to be farther away from you than it really is. • Try not to pass more than one vehicle at a time on two-lane roads. Reconsider before passing the next vehicle. • Do not overtake a slowly moving vehicle too rapidly. Even though the brake lamps are not flashing, it may be slowing down or starting[...]

If you have the Traction Assist System (TAS), remember: It helps avoid only the acceleration skid. See Traction Assist System (TAS) on page 4-9 . If you do not have this system, or if the system is off, then an acceleration skid is also best handled by easing your foot off the accelerator pedal. If your vehicle starts to slide, ease your foot off the accelerator pedal and quickly steer the way you want the vehicle to go. If you start steering quickly enough, your vehicle may straighten out. Always be ready for a second skid if it occurs. Of course, traction is reduced when water, snow, ice, gravel, or other material is on the road. For safety, you will want to slow down and adjust your drivi[...]

If you think you will need some more ground clearance at the front of your vehicle, you can remove the front bumper lower air dam. The front bumper lower air dam is held in place by a series of push-pins located around the lower edge of the front bumper. The push-pins are accessible from underneath the front bumper. The following steps must be performed on each of the push-pins to remove the air dam: 1. Insert a tool into the push-pin slot and pull downward until the push-pin snaps loose. 4-18[...]

2. While continuing to pull downward on the push-pin, squeeze and turn the expandable end of the push-pin with a tool until it releases from the retainer. 3. Pull the push-pins and lower dam assembly away from the retainers until the lower dam is free. When you are back on roads, though, be sure to replace the air dam. Notice: Operating your vehicle for extended periods without the front bumper lower air dam installed can cause improper air flow to the engine and may allow things like fog lamps or tow hooks on the front of your vehicle to be damaged. Always be sure to replace the front bumper air dam when you are finished off-road driving. 4-19[...]

To reinstall the lower air dam, do the following: 1. Line up each push-pin with its intended retainer and push the washer portion of the push-pin toward the retainer until it locks into place. 2. Push the flat end of the push-pin toward the retainer until it locks into place, making sure each is secure. Before You Go Of f-Roading There are some things to do before you go out. For example, be sure to have all necessary maintenance and service work done. Check to make sure all underbody shields (if equipped) are properly attached. Be sure you read all the information about your four-wheel-drive vehicle in this manual. Is there enough fuel? Is the spare tire fully inflated? Are the fluid lev[...]

{ CAUTION: • Cargo on the load floor piled higher than the seatbacks can be thrown forward during a sudden stop. You or your passengers could be injured. Keep cargo below the top of the seatbacks. • Unsecured cargo on the load floor can be tossed about when driving over rough terrain. You or your passengers can be struck by flying objects. Secure the cargo properly. • Heavy loads on the roof raise the vehicle’s center of gravity, making it more likely to roll over. You can be seriously or fatally injured if the vehicle rolls over. Put heavy loads inside the cargo area, not on the roof. Keep cargo in the cargo area as far forward and low as possible. You will find other important [...]

Traveling to Remote Areas It makes sense to plan your trip, especially when going to a remote area. Know the terrain and plan your route. You are much less likely to get bad surprises. Get accurate maps of trails and terrain. Try to learn of any blocked or closed roads. It is also a good idea to travel with at least one other vehicle. If something happens to one of them, the other can help quickly. Does your vehicle have a winch? If so, be sure to read the winch instructions. In a remote area, a winch can be handy if you get stuck. But you will want to know how to use it properly. Getting Familiar with Of f-Road Driving It is a good idea to practice in an area that is safe and close to home [...]

Scanning the Terrain Off-road driving can take you over many dif ferent kinds of terrain. You need to be familiar with the terrain and its many different features. Here are some things to consider. Surface Conditions: Of f-roading can take you over hard-packed dirt, gravel, rocks, grass, sand, mud, snow or ice. Each of these surfaces affects the steering, acceleration and braking of your vehicle in different ways. Depending upon the kind of surface you are on, you may experience slipping, sliding, wheel spinning, delayed acceleration, poor traction and longer braking distances. Surface Obstacles: Unseen or hidden obstacles can be hazardous. A rock, log, hole, rut or bump can startle you if y[...]

Driving on Of f-Road Hills Off-road driving often takes you up, down or across a hill. Driving safely on hills requires good judgment and an understanding of what your vehicle can and cannot do. There are some hills that simply cannot be driven, no matter how well built the vehicle. { CAUTION: Many hills are simply too steep for any vehicle. If you drive up them, you will stall. If you drive down them, you cannot control your speed. If you drive across them, you will roll over. You could be seriously injured or killed. If you have any doubt about the steepness, do not drive the hill. Approaching a Hill When you approach a hill, you need to decide if it is one of those hills that is just too [...]

Driving Uphill Once you decide you can safely drive up the hill, you need to take some special steps. • Use a low gear and get a firm grip on the steering wheel. • Get a smooth start up the hill and try to maintain your speed. Do not use more power than you need, because you do not want your wheels to start spinning or sliding. • Try to drive straight up the hill if at all possible. If the path twists and turns, you might want to find another route. { CAUTION: Turning or driving across steep hills can be dangerous. You could lose traction, slide sideways, and possibly roll over. You could be seriously injured or killed. When driving up hills, always try to go straight up. • Ease up[...]

Q: What should I do if my vehicle stalls, or is about to stall, and I cannot make it up the hill? A: If this happens, there are some things you should do, and there are some things you must not do. First, here is what you should do: • Push the brake pedal to stop the vehicle and keep it from rolling backwards. Also, apply the parking brake. • If your engine is still running, shift the transmission to REVERSE (R), release the parking brake, and slowly back down the hill in REVERSE (R). • If your engine has stopped running, you will need to restart it. With the brake pedal pressed and the parking brake still applied, shift the transmission to PARK (P) (or shift to NEUTRAL if your vehicle[...]

Q: Suppose, after stalling, I try to back down the hill and decide I just cannot do it. What should I do? A: Set the parking brake, put your transmission in PARK (P), or the manual transmission in FIRST (1), and turn off the engine. Leave the vehicle and go get some help. Exit on the uphill side and stay clear of the path the vehicle would take if it rolled downhill. Do not shift the transfer case to NEUTRAL when you leave the vehicle. Leave it in some gear. { CAUTION: Shifting the transfer case to NEUTRAL can cause your vehicle to roll even if the transmission is in PARK (P) (or, if you have the manual transmission, even if you are in gear). This is because the NEUTRAL position on the trans[...]

Driving Downhill When off-roading takes you downhill, you will want to consider a number of things: • How steep is the downhill? Will I be able to maintain vehicle control? • What is the surface like? Smooth? Rough? Slippery? Hard-packed dirt? Gravel? • Are there hidden surface obstacles? Ruts? Logs? Boulders? • What is at the bottom of the hill? Is there a hidden creek bank or even a river bottom with large rocks? If you decide you can go down a hill safely, then try to keep your vehicle headed straight down, and use a low gear. This way, engine drag can help your brakes and they will not have to do all the work. Descend slowly, keeping your vehicle under control at all times. { CAU[...]

Q: Am I likely to stall when going downhill? A: It is much more likely to happen going uphill. But if it happens going downhill, here is what to do. 1. Stop your vehicle by applying the regular brakes. Apply the parking brake. 2. Shift to PARK (P), or to NEUTRAL with the manual transmission, and, while still braking, restart the engine. 3. Shift back to a low gear, release the parking brake, and drive straight down. 4. If the engine will not start, get out and get help. Driving Across an Incline Sooner or later, an off-road trail will probably go across the incline of a hill. If this happens, you have to decide whether to try to drive across the incline. Here are some things to consider: •[...]

Q: What if I am driving across an incline that is not too steep, but I hit some loose gravel and start to slide downhill. What should I do? A: If you feel your vehicle starting to slide sideways, turn downhill. This should help straighten out the vehicle and prevent the side slipping. However, a much better way to prevent this is to get out and “walk the course” so you know what the surface is like before you drive it. Stalling on an Incline If your vehicle stalls when you are crossing an incline, be sure you, and any passengers, get out on the uphill side, even if the door there is harder to open. If you get out on the downhill side and the vehicle starts to roll over, you will be right[...]

Driving in Mud, Sand, Snow or Ice When you drive in mud, snow or sand, your wheels will not get good traction. You cannot accelerate as quickly, turning is more diff icult, and you will need longer braking distances. It is best to use a low gear when you are in mud — the deeper the mud, the lower the gear. In really deep mud, the idea is to keep your vehicle moving so you do not get stuck. When you drive on sand, you will sense a change in wheel traction. But it will depend upon how loosely packed the sand is. On loosely packed sand, such as on beaches or sand dunes, your tires will tend to sink into the sand. This has an effect on steering, accelerating and braking. Drive at a reduced spe[...]

If the water is not too deep, drive slowly through it. At faster speeds, water splashes on your ignition system and your vehicle can stall. Stalling can also occur if you get your tailpipe under water. And, as long as your tailpipe is under water, you will never be able to start your engine. When you go through water, remember that when your brakes get wet, it may take you longer to stop. { CAUTION: Driving through rushing water can be dangerous. Deep water can sweep your vehicle downstream and you and your passengers could drown. If it is only shallow water, it can still wash away the ground from under your tires, and you could lose traction and roll the vehicle over. Do not drive through r[...]

Driving at Night Night driving is more dangerous than day driving. One reason is that some drivers are likely to be impaired — by alcohol or drugs, with night vision problems, or by fatigue. Here are some tips on night driving. • Drive defensively. • Do not drink and drive. • Adjust the inside rearview mirror to reduce the glare from headlamps behind you. • Since you cannot see as well, you may need to slow down and keep more space between you and other vehicles. • Slow down, especially on higher speed roads. Your vehicle’s headlamps can light up only so much road ahead. • In remote areas, watch for animals. • If you are tired, pull off the road in a safe place and rest. No[...]

You can be temporarily blinded by approaching headlamps. It can take a second or two, or even several seconds, for your eyes to re-adjust to the dark. When you are faced with severe glare, as from a driver who does not lower the high beams, or a vehicle with misaimed headlamps, slow down a little. Avoid staring directly into the approaching headlamps. Keep the windshield and all the glass on your vehicle clean — inside and out. Glare at night is made much worse by dirt on the glass. Even the inside of the glass can build up a film caused by dust. Dirty glass makes lights dazzle and flash more than clean glass would, making the pupils of your eyes contract repeatedly. Remember that the he[...]

The heavier the rain, the harder it is to see. Even if your windshield wiper blades are in good shape, a heavy rain can make it harder to see road signs and traff ic signals, pavement markings, the edge of the road, and even people walking. It is wise to keep your wiping equipment in good shape and keep your windshield washer fluid reservoir filled with washer fluid. Replace your windshield wiper inserts when they show signs of streaking or missing areas on the windshield, or when strips of rubber start to separate from the inserts. { CAUTION: Wet brakes can cause accidents. They will not work as well in a quick stop and may cause pulling to one side. You could lose control of the vehicle[...]

Driving Through Deep Standing Water Notice: If you drive too quickly through deep puddles or standing water, water can come in through your engine’s air intake and badly damage your engine. Never drive through water that is slightly lower than the underbody of your vehicle. If you cannot avoid deep puddles or standing water, drive through them very slowly. Driving Through Flowing Water { CAUTION: Flowing or rushing water creates strong forces. If you try to drive through flowing water, as you might at a low water crossing, your vehicle can be carried away. As little as six inches of flowing water can carry away a smaller vehicle. If this happens, you and other vehicle occupants could dro[...]

City Driving One of the biggest problems with city streets is the amount of traff ic on them. You will want to watch out for what the other drivers are doing and pay attention to traff ic signals. Here are ways to increase your safety in city driving: • Know the best way to get to where you are going. Get a city map and plan your trip into an unknown part of the city just as you would for a cross-country trip. • Try to use the freeways that rim and crisscross most large cities. You will save time and energy. See Freeway Driving on page 4-38 . • Treat a green light as a warning signal. A traff ic light is there because the corner is busy enough to need it. When a light turns green, and [...]

Freeway Driving Mile for mile, freeways — also called thruways, parkways, expressways, turnpikes, or superhighways — are the safest of all roads. But they have their own special rules. The most important advice on freeway driving is: Keep up with traff ic and keep to the right. Drive at the same speed most of the other drivers are driving. Too-fast or too-slow driving breaks a smooth traff ic flow. Treat the left lane on a freeway as a passing lane. At the entrance, there is usually a ramp that leads to the freeway. If you have a clear view of the freeway as you drive along the entrance ramp, you should begin to check traff ic. Try to determine where you expect to blend with the flow. [...]

When you want to leave the freeway, move to the proper lane well in advance. If you miss your exit, do not, under any circumstances, stop and back up. Drive on to the next exit. The exit ramp can be curved, sometimes quite sharply. The exit speed is usually posted. Reduce your speed according to your speedometer, not to your sense of motion. After driving for any distance at higher speeds, you may tend to think you are going slower than you actually are. Before Leaving on a Long Trip Make sure you are ready. Try to be well rested. If you must start when you are not fresh — such as after a day’s work — do not plan to make too many miles that first part of the journey. Wear comfortable [...]

Highway Hypnosis Is there actually such a condition as highway hypnosis? Or is it just plain falling asleep at the wheel? Call it highway hypnosis, lack of awareness, or whatever. There is something about an easy stretch of road with the same scenery, along with the hum of the tires on the road, the drone of the engine, and the rush of the wind against the vehicle that can make you sleepy. Do not let it happen to you! If it does, your vehicle can leave the road in less than a second, and you could crash and be injured. What can you do about highway hypnosis? First, be aware that it can happen. Then here are some tips: • Make sure your vehicle is well ventilated, with a comfortably cool int[...]

• Keep your vehicle in good shape. Check all fluid levels and also the brakes, tires, cooling system, and transmission. These parts can work hard on mountain roads. { CAUTION: If you do not shift down, your brakes could get so hot that they would not work well. You would then have poor braking or even none going down a hill. You could crash. Shift down to let your engine assist your brakes on a steep downhill slope. { CAUTION: Coasting downhill in NEUTRAL (N) or with the ignition off is dangerous. Your brakes will have to do all the work of slowing down. They could get so hot that they would not work well. You would then have poor braking or even none going down a hill. You could crash. A[...]

Winter Driving Here are some tips for winter driving: • Have your vehicle in good shape for winter. • You may want to put winter emergency supplies in your vehicle. Also see Tires on page 5-73 . Include an ice scraper, a small brush or broom, a supply of windshield washer fluid, a rag, some winter outer clothing, a small shovel, a flashlight, a red cloth, and reflective warning triangles. And, if you will be driving under severe conditions, include a small bag of sand, a piece of old carpet, or a couple of burlap bags to help provide traction. Be sure you properly secure these items in your vehicle. Driving on Snow or Ice Most of the time, those places where the tires meet the road pr[...]

What is the worst time for this? Wet ice. Very cold snow or ice can be slick and hard to drive on. But wet ice can be even more trouble because it may offer the least traction of all. You can get wet ice when it is about freezing, 32°F (0°C), and freezing rain begins to fall. Try to avoid driving on wet ice until salt and sand crews can get there. Whatever the condition — smooth ice, packed, blowing, or loose snow — drive with caution. If you have the Traction Assist System (TAS), it will improve your ability to accelerate when driving on a slippery road. But you can turn the TAS off if you ever need to. You should turn the TAS off if your vehicle ever gets stuck in sand, mud, ice, or [...]

Your Anti-Lock Brake System (ABS) improves your vehicle’s stability when you make a hard stop on a slippery road. Even though you have ABS, you will want to begin stopping sooner than you would on dry pavement. See Anti-Lock Brake System (ABS) on page 4-7 . • Allow greater following distance on any slippery road. • Watch for slippery spots. The road might be fine until you hit a spot that is covered with ice. On an otherwise clear road, ice patches may appear in shaded areas where the sun cannot reach, such as around clumps of trees, behind buildings, or under bridges. Sometimes the surface of a curve or an overpass may remain icy when the surrounding roads are clear. If you see a pat[...]

You can run the engine to keep warm, but be careful. { CAUTION: Snow can trap exhaust gases under your vehicle. This can cause deadly CO (carbon monoxide) gas to get inside. CO could overcome you and kill you. You cannot see it or smell it, so you might not know it is in your vehicle. Clear away snow from around the base of your vehicle, especially any that is blocking your exhaust pipe. And check around again from time to time to be sure snow does not collect there. Open a window just a little on the side of the vehicle that is away from the wind. This will help keep CO out. Run your engine only as long as you must. This saves fuel. When you run the engine, make it go a little faster than j[...]

If Your Vehicle is Stuck in Sand, Mud, Ice or Snow In order to free your vehicle when it is stuck, you will need to spin the wheels, but you do not want to spin your wheels too fast. The method known as rocking can help you get out when you are stuck, but you must use caution. { CAUTION: If you let your tires spin at high speed, they can explode, and you or others could be injured. And, the transmission or other parts of the vehicle can overheat. That could cause an engine compartment fire or other damage. When you are stuck, spin the wheels as little as possible. Do not spin the wheels above 35 mph (55 km/h) as shown on the speedometer. Notice: Spinning your wheels can destroy parts of you[...]

Recovery Hooks (Except SS Model) Notice: SS Models have recovery hooks that are concealed by the front bumper trim covering. Use of the recovery hooks could cause damage to your vehicle. If you have the SS Model, do not use the recovery hooks. { CAUTION: These hooks, when used, are under a lot of force. Always pull the vehicle straight out. Never pull on the hooks at a sideways angle. The hooks could break off and you or others could be injured from the chain or cable snapping back. Notice: Never use recovery hooks to tow the vehicle. Your vehicle could be damaged and it would not be covered by warranty. Your vehicle may have recovery hooks at the front of the vehicle. You may need to use th[...]

Loading Your Vehicle It is very important to know how much weight your vehicle can carry. This weight is called the vehicle capacity weight and includes the weight of all occupants, cargo, and all nonfactory-installed options. Two labels on your vehicle show how much weight it was designed to carry, the Tire and Loading Information label and the Certification/Tire label. { CAUTION: Do not load your vehicle any heavier than the Gross Vehicle Weight Rating (GVWR), or either the maximum front or rear Gross Axle Weight Rating (GAWR). If you do, parts on your vehicle can break, and it can change the way your vehicle handles. These could cause you to lose control and crash. Also, overloading can [...]

The Tire and Loading Information label also shows the size of the original equipment tires (C) and the recommended cold tire inflation pressures (D). For more information on tires and inflation see Tires on page 5-73 and Inflation - Tire Pressure on page 5-80 . There is also important loading information on the vehicle Certification/Tire label. It tells you the Gross Vehicle Weight Rating (GVWR) and the Gross Axle Weight Rating (GAWR) for the front and rear axles. See “Certification/Tire Label” later in this section. Steps for Determining Correct Load Limit 1. Locate the statement “The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs” on your vehicle?[...]

Item Description Total A Vehicle Capacity Weight for Example 1 = 1,000 lbs (453 kg) B Subtract Occupant Weight 150 lbs (68 kg) × 2 = 300 lbs (136 kg) C Available Occupant and Cargo Weight = 700 lbs (317 kg) Item Description Total A Vehicle Capacity Weight for Example 2 = 1,000 lbs (453 kg) B Subtract Occupant Weight 150 lbs (68 kg) × 5 = 750 lbs (136 kg) C Available Cargo Weight = 250 lbs (113 kg) Example 1 Example 2 4-50[...]

Item Description Total A Vehicle Capacity Weight for Example 3 = 1,000 lbs (453 kg) B Subtract Occupant Weight 200 lbs (91 kg) × 5 = 1000 lbs (453 kg) C Available Cargo Weight = 0 lbs (0 kg) Refer to your vehicle’s tire and loading information label for specific information about your vehicle’s capacity weight and seating positions. The combined weight of the driver, passengers, and cargo should never exceed your vehicle’s capacity weight. Certification/Tire Label A vehicle specific Certification/Tire label is found on the rear edge of the driver’s door. The label shows the size of your vehicle’s original tires and the inflation pressures needed to obtain the gross weight cap[...]

The Certification/Tire label also tells you the maximum weights for the front and rear axles, called Gross Axle Weight Rating (GAWR). To find out the actual loads on your front and rear axles, you need to go to a weigh station and weigh your vehicle. Your dealer can help you with this. Be sure to spread out your load equally on both sides of the centerline. Never exceed the GVWR for your vehicle, or the GAWR for either the front or rear axle. The Certification/Tire label also contains important information about your Front Axle Reserve Capacity. See “What is front axle reserve capacity, and how do I calculate it?” under Adding a Snow Plow or Similar Equipment on page 4-54 . { CAUTION:[...]

If you put things inside your vehicle — like suitcases, tools, packages, or anything else — they go as fast as the vehicle goes. If you have to stop or turn quickly, or if there is a crash, they will keep going. { CAUTION: Things you put inside your vehicle can strike and injure people in a sudden stop or turn, or in a crash. • Put things in the cargo area of your vehicle. Try to spread the weight evenly. • Never stack heavier things, like suitcases, inside the vehicle so that some of them are above the tops of the seats. • Do not leave an unsecured child restraint in your vehicle. • When you carry something inside the vehicle, secure it whenever you can. • Do not leave a seat [...]

Add-On Equipment When you carry removable items, you may need to put a limit on how many people you carry inside your vehicle. Be sure to weigh your vehicle before you buy and install the new equipment. Notice: Overloading your vehicle may cause damage. Repairs would not be covered by your warranty. Do not overload your vehicle. Remember not to exceed the Gross Axle Weight Rating (GAWR) of the front or rear axle. *Equipment Maximum Weight Ladder Rack and Cargo 750 lbs (340 kg) Cross Toolbox and Cargo 400 lbs (181 kg) Side Boxes and Cargo 250 lbs per side (113 kg per side) *The combined weight for all rail-mounted equipment should not exceed 1,000 lbs (454 kg), excluded 1500 crew cab models w[...]

Q: How heavy can a snow plow safely be? A: The plow your vehicle can carry depends on many things, such as: • The options your vehicle came with, and the weight of those options. • The weight and number of passengers you intend to carry. • The weight of items you have added to your vehicle, like a tool box or truck cap. • The total weight of any additional cargo you intend to carry. Say, for example, you have a 700 lb (318 kg) snow plow. The total weight of all occupants and cargo inside the cab should not exceed 300 lb (135 kg). This means that you may only be able to carry one passenger. But, even this may be too much if you have got other equipment already adding to the weight of [...]

Q: What is front axle reserve capacity, and how do I calculate it? A: Front axle reserve capacity is the difference between your front gross axle weight rating (GAWR) and the front axle weight of your vehicle with full fuel and passengers. Basically, it is the amount of weight you can add to your front axle before reaching your front GAWR. The front axle reserve capacity for your vehicle can be found in the lower right corner of the Certification/Tire label, as shown. In order to calculate the amount of weight any front accessory, such as a snow plow, is adding to the front axle, use the following formula: (W x (A + W.B.)) /W.B.= Weight the accessory is adding to the front axle. Where: W = [...]

For example, adding a 700 lb (318 kg) snow plow actually adds more than 700 lbs (318 kg) to the front axle. Using the formula, if the snow plow is 4 ft (122 cm) in front of the front axle and the wheel base is 10 ft (305 cm), then: W = 700 lb (318 kg) A = 4 ft (122 cm) W.B. = 10 ft (305 cm) (W x (A + W.B.))/W.B. = (700 x (4 + 10))/10 = 980 lbs (445 kg) So, if your truck’s front axle reserve capacity is more than 980 lbs (445 kg), you could add the snow plow without exceeding the front GAWR. Q: What if I want to add heavier equipment to my vehicle? A: You can add heavier equipment on the front of the vehicle if you compensate for it by carrying fewer passengers, less cargo, or by positionin[...]

Q: What is total vehicle reserve capacity? A: This is the difference between your GVWR and the weight of your truck with full fuel and passengers. It is the amount of weight you can add to your vehicle before reaching your GVWR. Keep in mind that reserve capacity numbers are intended as a guide when selecting the amount of equipment or cargo your truck can carry. If you are unsure of your vehicle’s front, rear, or total weight, go to a weigh station and weigh your vehicle. Your dealer can also help you with this. The total vehicle reserve capacity for your vehicle can be found in the lower right corner of the Certification/Tire label as shown previously. See your dealer for additional adv[...]

Truck-Camper Loading Information Notice: Installing a truck-camper to a vehicle that is equipped with the SS trim package could damage the vehicle. Do not install a truck-camper on a vehicle equipped with the SS trim package. A vehicle specific Truck-Camper Loading information label is attached to the inside of your vehicle’s glove box. This label will tell you if your vehicle can carry a slide-in camper, how much of a load your vehicle can carry, and how to correctly spread out the load. Also, it will help you match the right slide-in camper to your vehicle. When you carry a slide-in camper, the total cargo load of your vehicle is the weight of the camper, plus the following: • Everyth[...]

Here is an example of proper truck and camper match: A. Camper Center of Gravity B. Recommended Center of Gravity Location Zone When the truck is used to carry a slide-in camper, the total cargo load of the truck consists of the manufacturer’s camper weight figure, the weight of installed additional camper equipment not included in the manufacturer’s camper weight figure, the weight of camper cargo, and the weight of passengers in the camper. The total cargo load should not exceed the truck’s cargo weight rating and the camper’s center of gravity (A) should fall within the truck’s recommended center of gravity zone (B) when installed. You must weigh any accessories or other equip[...]

Secure loose items to prevent weight shifts that could affect the balance of your vehicle. When the truck-camper is loaded, drive to a scale and weigh the front and the rear wheels separately to determine axle loads. Individual axle loads should not exceed either of the GAWRs. The total of the front and rear axle loads should not exceed your vehicle’s GVWR. These ratings are given on the vehicle certification label attached to the rear edge of the driver’s door. See “Certification/Tire Label” under Loading Your Vehicle on page 4-48 . If weight ratings are exceeded, move or remove items to bring all weights below the ratings. When you install and load your slide-in camper, check the[...]

Recreational Vehicle Towing Recreational vehicle towing means towing your vehicle behind another vehicle – such as behind a motorhome. The two most common types of recreational vehicle towing are known as dinghy towing, towing your vehicle will all four wheels on the ground, and dolly towing, towing your vehicle with two wheels on the ground and two wheels up on a device known as a “dolly”. With the proper preparation and equipment, many vehicles can be towed in these ways. See “Dinghy Towing” and “Dolly Towing” following. Here are some important things to consider before you do recreational vehicle towing: • What’s the towing capacity of the towing vehicle? Be sure you rea[...]

Four-Wheel-Drive Vehicles Use the following procedure to tow your vehicle: 1. Shift an automatic transmission to PARK (P), or a manual transmission to FIRST (1). 2. Turn the engine of f, but leave the ignition on. 3. Firmly set the parking brake. 4. Securely attach the vehicle being towed to the tow vehicle. { CAUTION: Shifting a four-wheel-drive vehicle’s transfer case into NEUTRAL can cause your vehicle to roll even if the transmission is in PARK (P) for an automatic transmission, or if your vehicle is in gear, for a manual transmission. You or others could be injured. Make sure the parking brake is firmly set before you shift the transfer case to NEUTRAL. 5. Shift the transfer case to [...]

Dolly Towing Front Towing (Front Wheels Of f the Ground) Two-Wheel-Drive Vehicles Notice: If you tow a two-wheel-drive vehicle with the rear wheels on the ground, the transmission could be damaged. The repairs would not be covered by your warranty. Never tow your vehicle with the rear wheels on the ground. Two-wheel-drive vehicles should not be towed with the rear wheels on the ground. Two-wheel-drive transmissions have no provisions for internal lubrication while being towed. To dolly tow a two-wheel-drive vehicle, you must tow the vehicle with the rear wheels on the dolly. See “Rear Towing (Rear Wheels Off the Ground)” later in this section for more information. Four-Wheel-Drive Vehicl[...]

{ CAUTION: Shifting a four-wheel-drive vehicle’s transfer case into NEUTRAL can cause your vehicle to roll even if the transmission is in PARK (P) for an automatic transmission, or if your vehicle is in gear, for a manual transmission. You or others could be injured. Make sure the parking brake is firmly set before you shift the transfer case to NEUTRAL. 6. Shift the transfer case to NEUTRAL.

Towing a Trailer Do not tow a trailer during break-in. See New Vehicle Break-In on page 2-20 for more information. { CAUTION: If you do not use the correct equipment and drive properly, you can lose control when you pull a trailer. For example, if the trailer is too heavy, the brakes may not work well — or even at all. You and your passengers could be seriously injured. Pull a trailer only if you have followed all the steps in this section. Ask your dealer for advice and information about towing a trailer with your vehicle. Notice: Pulling a trailer improperly can damage your vehicle and result in costly repairs not covered by your warranty. To pull a trailer correctly, follow the advice i[...]

If You Do Decide To Pull A Trailer Notice: Pulling a fifth-wheel trailer with a vehicle that is equipped with the SS trim package could damage the vehicle. Do not pull a fifth-wheel trailer with a vehicle equipped with the SS trim package. If you do, here are some important points: • There are many different laws, including speed limit restrictions, having to do with trailering. Make sure your rig will be legal, not only where you live but also where you’ll be driving. A good source for this information can be state or provincial police. • Consider using a sway control. See “Hitches” later in this section. • Don’t tow a trailer at all during the first 500 miles (800 km) your[...]

Tow/Haul Mode Tow/Haul is a feature on automatic transmission equipped vehicles that assists when pulling a heavy trailer or a large or heavy load. See Tow/Haul Mode on page 2-30 for more information. Tow/Haul is designed to be most effective when the vehicle and trailer combined weight is at least 75% of the vehicle’s Gross Combined Weight Rating (GCWR). See “Weight of the Trailer” later in the section. Tow/Haul is most useful under the following driving conditions: • When pulling a heavy trailer or a large or heavy load through rolling terrain. • When pulling a heavy trailer or a large or heavy load in stop and go traff ic. • When pulling a heavy trailer or a large or heavy loa[...]

Weight of the Trailer Tongue The tongue load (A) of any trailer is an important weight to measure because it affects the total or gross weight of your vehicle. The Gross Vehicle Weight (GVW) includes the curb weight of the vehicle, any cargo you may carry in it, and the people who will be riding in the vehicle. If you have a lot of options, equipment, passengers or cargo in your vehicle, it will reduce the tongue weight your vehicle can carry, which will also reduce the trailer weight your vehicle can tow. And if you will tow a trailer, you must add the tongue load to the GVW because your vehicle will be carrying that weight, too. See Loading Your Vehicle on page 4-48 for more information ab[...]

Trailering may be limited by the vehicle’s ability to carry tongue weight. Tongue weight cannot cause the vehicle to exceed the GVWR (Gross Vehicle Weight Rating) or the RGAWR (Rear Gross Axle Weight Rating). The effect of additional weight may reduce your trailering capacity more than the total of the additional weight. Consider the following example: A vehicle model base weight is 5,500 lbs (2 495 kg); 2,800 lbs (1 270 kg) at the front axle and 2,700 lbs (1 225 kg) at the rear axle. It has a GVWR of 7,200 lbs (3 266 kg), a RGAWR of 4,000 lbs (1 814 kg) and a GCWR (Gross Combination Weight Rating) of 14,000 lbs (6 350 kg). The trailer rating should be: You can expect tongue weight to be a[...]

The effect of tongue weight is about 1.5 times the actual weight. Dividing the 900 lbs (408 kg) by 1.5 leaves you with being able to handle only 600 lbs (272 kg) of tongue weight. Since tongue weight is usually at least 10 percent of total loaded trailer weight, you can expect that the largest trailer your vehicle can properly handle is 6,000 lbs (2 721 kg). It is important that you make sure your vehicle does not exceed any of its ratings — GCWR, GVWR, RGAWR, Maximum Trailer Rating or Tongue Weight. The only way to be sure you are not exceeding any of these ratings is to weigh your vehicle and trailer. Total Weight on Your Vehicle’s Tires Be sure your vehicle’s tires are inflated to [...]

If you will be pulling a trailer that, when loaded, will weigh more than 5,000 lbs (2 270 kg) be sure to use a properly mounted weight-distributing hitch and sway control of the proper size. This equipment is very important for proper vehicle loading and good handling when driving. Always use a sway control if the trailer will weigh more than these limits. You can ask a hitch dealer about sway controls. Fifth Wheel and Gooseneck Trailering Notice: Pulling a fifth-wheel trailer with a vehicle that is equipped with the SS trim package could damage the vehicle. Do not pull a fifth-wheel trailer with a vehicle equipped with the SS trim package. Fifth wheel and gooseneck trailers can be used wi[...]

Trailer Brakes If your trailer weighs more than 2,000 lbs (900 kg) loaded, then it needs its own brakes – and they must be adequate. Be sure to read and follow the instructions for the trailer brakes so you’ll be able to install, adjust and maintain them properly. Your trailer brake system can tap into the vehicle’s hydraulic brake system only if: • The trailer parts can withstand 3,000 psi (20 650 kPa) of pressure. • The trailer’s brake system will use less than 0.02 cubic inch (0.3 cc) of fluid from your vehicle’s master cylinder. Otherwise, both braking systems won’t work well. You could even lose your brakes. If everything checks out this far, make the brake tap at the p[...]

Towing a trailer requires a certain amount of experience. Before setting out for the open road, you’ll want to get to know your rig. Acquaint yourself with the feel of handling and braking with the added weight of the trailer. And always keep in mind that the vehicle you are driving is now a good deal longer and not nearly as responsive as your vehicle is by itself. Before you start, check all trailer hitch parts and attachments, safety chains, electrical connector, lamps, tires and mirror adjustment. If the trailer has electric brakes, start your vehicle and trailer moving and then apply the trailer brake controller by hand to be sure the brakes are working. This lets you check your elect[...]

Turn Signals When Towing a Trailer The arrows on your instrument panel will flash whenever you signal a turn or lane change. Properly hooked up, the trailer lamps will also flash, telling other drivers you’re about to turn, change lanes or stop. When towing a trailer, the arrows on your instrument panel will flash for turns even if the bulbs on the trailer are burned out. Thus, you may think drivers behind you are seeing your signal when they are not. It’s important to check occasionally to be sure the trailer bulbs are still working. Driving On Grades Reduce speed and shift to a lower gear before you start down a long or steep downgrade. If you don’t shift down, you might have to u[...]

Parking on Hills { CAUTION: You really should not park your vehicle, with a trailer attached, on a hill. If something goes wrong, your rig could start to move. People can be injured, and both your vehicle and the trailer can be damaged. But if you ever have to park your rig on a hill, here’s how to do it: 1. Apply your regular brakes, but don’t shift into PARK (P) yet for an automatic transmission, or into gear for a manual transmission. 2. Have someone place chocks under the trailer wheels. 3. When the wheel chocks are in place, release the regular brakes until the chocks absorb the load. 4. Reapply the regular brakes. Then apply your parking brake and shift into PARK (P) for an automat[...]

When You Are Ready to Leave After Parking on a Hill 1. Apply your regular brakes and hold the pedal down while you: • Start your engine • Shift into a gear • Release the parking brake 2. Let up on the brake pedal. 3. Drive slowly until the trailer is clear of the chocks. 4. Stop and have someone pick up and store the chocks. Maintenance When Trailer Towing Your vehicle will need service more often when you’re pulling a trailer. See Scheduled Maintenance (Gasoline Engine) on page 6-4 for more information. Things that are especially important in trailer operation are automatic transmission fluid (don’t overfill), engine oil, axle lubricant, belt, cooling system and brake system. Ea[...]

If your trailer is equipped with electric brakes, you can get a jumper harness (electric trailer brake control) with a trailer battery feed fuse from your dealer. If you need to tow a light-duty trailer with a standard four-way round pin connector, you can also get an adapter from your dealer. Heavy-DutyTrailer Wiring Harness Package For vehicles equipped with heavy duty trailering, the harness is connected to the trailer mounted to the hitch platform. The eight-wire harness contains the following trailer circuits: • Yellow: Left Stop/Turn Signal • Dark Green: Right Stop/Turn Signal • Brown: Taillamps • White: Ground • Light Green: Back-up Lamps • Light Blue: CHMSL* • Red: Batt[...]

Camper/Fifth-Wheel Trailer Wiring Package Notice: Pulling a fifth-wheel trailer with a vehicle that is equipped with the SS trim package could damage the vehicle. Do not pull a fifth-wheel trailer with a vehicle equipped with the SS trim package.

A connector will have to be added to the wiring harness which connects to the camper. The eight-wire harness contains the following camper/trailer circuits: • Yellow: Left Stop/Turn Signal • Dark Green: Right Stop/Turn Signal • Brown: Taillamps • White: Ground • Light Green: Back-up Lamps ?[...]

Electric Brake Control Jumper { CAUTION: Be sure to use only the correct trailer brake harness, the one intended for use on your vehicle. If you use some other trailer brake harness, even if it seems to fit, your trailer brakes may not work at all. You could have a crash in which you or others could be injured. Use only the trailer brake harness intended for your vehicle. If it is no longer available to you, be sure to get a proper replacement from your dealer. This harness is included with your vehicle as part of the heavy-duty trailer wiring package. This harness is for an electric brake controller and includes a trailer battery feed fuse. It should be installed by your dealer or a quali?[...]

Auxiliary Battery The auxiliary battery provision can be used to supply electrical power to additional equipment that you may choose to add, such as a slide-in camper. If your vehicle has this provision, this relay will be located on the passenger’s side of the vehicle, next to the auxiliary battery. When using this provision, connection should only be made to the upper stud (A) of the relay. Do not make connections to the lower stud (B) of the relay. The auxiliary battery circuit is protected by a megafuse located behind the auxiliary battery. Be sure to follow the proper installation instructions that are included with any electrical equipment that you install. Notice: Leaving electrical[...]

Trailer Recommendations You must subtract your hitch loads from the CWR for your vehicle. Weigh your vehicle with the trailer attached, so that you won’t go over the GVWR or GAWR. If you are using a weight-distributing hitch, weigh the vehicle without the spring bars in place. You’ll get the best performance if you spread out the weight of your load the right way, and if you choose the correct hitch and trailer brakes. For more information, see Towing a Trailer on page 4-67 . Power Take-Of f (PTO) Before using a Power Take-Off (PTO), if equipped, refer to the manufacturer’s or installer’s instructions. To engage a PTO on a vehicle with a manual transmission do the following: 1. Hold [...]

To use PTO speed control in Preset Mode (Factory Setting) do the following: 1. Engage the PTO. 2. Select PARK (P) or NEUTRAL (N) range. Apply the parking brake if NEUTRAL (N) is selected. Torque Converter Clutch (TCC) is not available in NEUTRAL (N) and is available only in PARK (P) when engine speed is above 1,100 rpm. 3. Make sure your foot is of f the brake pedal (and of f the clutch on vehicles equipped with a manual transmission). 4. Select the desired engine speed for PTO operation. Read the following preset mode information regarding operation. Preset Mode: PTO speed control mode is used for stationary applications. (PTO will remain engaged while mobile in the preset mode, however PTO[...]

Variable Mode: PTO speed control mode can be used for both stationary and mobile applications. This mode allows PTO to be controlled in a fashion similar to how cruise control sets vehicle speed. The operator can set to an rpm (between 800 and 2,200) with the cruise control feature or with the SET position on the PTO switch. The operator is then able to increase rpm in increments of 100, or “tap up” with the resume position on the cruise control. The operator can also decrease rpm in increments of 100 with the SET switch on the PTO or the cruise control. Vehicles not equipped with cruise control will not have the “tap up” capability. All engine speed values listed above are factory p[...]

Service Your dealer knows your vehicle best and wants you to be happy with it. We hope you will go to your dealer for all your service needs. You will get genuine GM parts and GM-trained and supported service people. We hope you will want to keep your GM vehicle all GM. Genuine GM parts have one of these marks: Accessories and Modifications When you add non-GM accessories to your vehicle they can affect your vehicle’s performance and safety, including such things as, braking, stability, ride and handling, emissions systems, aerodynamics, durability, and electronic systems like antilock brakes, traction control and stability control. Some of these accessories may even cause malfunction or [...]

Doing Your Own Service Work { CAUTION: You can be injured and your vehicle could be damaged if you try to do service work on a vehicle without knowing enough about it. • Be sure you have suff icient knowledge, experience, the proper replacement parts, and tools before you attempt any vehicle maintenance task. • Be sure to use the proper nuts, bolts, and other fasteners. English and metric fasteners can be easily confused. If you use the wrong fasteners, parts can later break or fall off. You could be hurt. If you want to do some of your own service work, you will want to use the proper service manual. It tells you much more about how to service your vehicle than this manual can. To order[...]

Fuel If your vehicle has a diesel engine, see “Diesel Fuel Requirements and Fuel System” in the DURAMAX ® Diesel Supplement. For vehicles with gasoline engines, please read this. Gasoline The 8th digit of your vehicle identification number (VIN) shows the code letter or number that identifies your engine. You will find the VIN at the top left of the instrument panel. See Vehicle Identification Number (VIN) on page 5-122 . If your vehicle has the 5.3L V8 engine (VIN Code Z), you may use either regular unleaded gasoline or ethanol fuel containing up to 85% ethanol (E85); also see Fuel E85 (85% Ethanol) on page 5-8 . In all other gasoline engines, use only regular unleaded gasoline. Ga[...]

California Fuel If your vehicle is certified to meet California Emissions Standards, it is designed to operate on fuels that meet California specifications. See the underhood emission control label. If this fuel is not available in states adopting California emissions standards, your vehicle will operate satisfactorily on fuels meeting federal specifications, but emission control system performance may be affected. The malfunction indicator lamp may turn on and your vehicle may fail a smog-check test. See Malfunction Indicator Lamp on page 3-45 . If this occurs, return to your authorized GM dealer for diagnosis. If it is determined that the condition is caused by the type of fuel used, re[...]

Fuel E85 (85% Ethanol) The 8th digit of your vehicle identification number (VIN) shows the code letter or number that identifies your engine. You will find the VIN at the top left of the instrument panel. See Vehicle Identification Number (VIN) on page 5-122 . If your vehicle has the 5.3L V8 engine (VIN Code Z only), you may use either regular unleaded gasoline or ethanol fuel containing up to 85% ethanol (E85); also see Fuel on page 5-6 . In all other engines, including the 5.3L V8 (VIN Code T), use only regular unleaded gasoline. Only vehicles that have the 5.3L V8 engine (VIN Code Z) may use 85% ethanol fuel (E85). General Motors encourages the use of E85 in vehicles that are designed[...]

E85 has less energy per gallon than gasoline, so you will need to refill your fuel tank more often when using E85 than when you are using gasoline. Regular unleaded gasoline is recommended when pulling a trailer. For payload capacity with ethanol fuel, see Loading Your Vehicle on page 4-48 . Notice: Some additives are not compatible with E85 fuel and may harm your fuel system. Damage caused by additives would not be covered by your new vehicle warranty. Do not use additives with E85 fuel. Notice: Your vehicle was not designed for fuel that contains methanol. Do not use fuel containing methanol. It can corrode metal parts in your fuel system and also damage the plastic and rubber parts. That[...]

Filling the Tank { CAUTION: Fuel vapor burns violently and a fuel fire can cause bad injuries. To help avoid injuries to you and others, read and follow all the instructions on the pump island. Turn off your engine when you are refueling. Do not smoke if you are near fuel or refueling your vehicle. Keep sparks, flames, and smoking materials away from fuel. Do not leave the fuel pump unattended when refueling your vehicle — this is against the law in some places. Keep children away from the fuel pump; never let children pump fuel. The tethered fuel cap is located behind a hinged fuel door on the driver’s side of the vehicle. To remove the fuel cap, turn it slowly counterclockwise. It wi[...]

If your vehicle is a dual fuel tank chassis cab model, and it runs out of fuel, refuel the front fuel tank first to ensure a quick restart. Be careful not to spill fuel. Do not top off or overfill the tank and wait a few seconds after you have finished pumping before removing the nozzle. Clean fuel from painted surfaces as soon as possible. See Washing Your Vehicle on page 5-118 . When replacing the fuel cap, turn it clockwise until it clicks. It will require more effort to turn the fuel cap on the last turn as you tighten it. Make sure the cap is fully installed. The diagnostic system can determine if the fuel cap has been left off or improperly installed. This would allow fuel to evapor[...]

Filling a Portable Fuel Container { CAUTION: Never fill a portable fuel container while it is in your vehicle. Static electricity discharge from the container can ignite the gasoline vapor. You can be badly burned and your vehicle damaged if this occurs. To help avoid injury to you and others: • Dispense gasoline only into approved containers. • Do not fill a container while it is inside a vehicle, in a vehicle’s trunk, pickup bed, or on any surface other than the ground. • Bring the fill nozzle in contact with the inside of the fill opening before operating the nozzle. Contact should be maintained until the filling is complete. • Do not smoke while pumping gasoline. Checking [...]

Engine Oil (Gasoline Engine) If your vehicle has a diesel engine, see “Engine Oil” in the DURAMAX ® Diesel Engine Supplement. If the CHECK OIL LEVEL light appears on the instrument cluster (except vehicles equipped with the 4.3L engine), it means you need to check your engine oil level right away. For more information, see Driver Information Center (DIC) on page 3-51 . You should check your engine oil level regularly; this is an added reminder. Checking Engine Oil It is a good idea to check your engine oil every time you get fuel. In order to get an accurate reading, the oil must be warm and the vehicle must be on level ground. The engine oil dipstick handle is a yellow loop. See Engine[...]

When to Add Engine Oil If the oil is below the cross-hatched area at the tip of the dipstick, you will need to add at least one quart/liter of oil. But you must use the right kind. This section explains what kind of oil to use. For engine oil crankcase capacity, see Capacities and Specifications on page 5-132 . Notice: Do not add too much oil. If the engine has so much oil that the oil level gets above the cross-hatched area that shows the proper operating range, the engine could be damaged. See Engine Compartment Overview on page 5-14 for the location of the engine oil fill cap. Be sure to add enough oil to put the level somewhere in the proper operating range. Push the dipstick all the w[...]

What Kind of Engine Oil to Use Look for two things: • GM6094M Your vehicle’s engine requires oil meeting GM Standard GM6094M. You should look for and use only an oil that meets GM Standard GM6094M. • SAE 5W-30 As shown in the viscosity chart, SAE 5W-30 is best for your vehicle. These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils such as SAE 20W-50. Oils meeting these requirements should also have the starburst symbol on the container. This symbol indicates that the oil has been certified by the American Petroleum Institute (API). You should look for this information on the oil container, and use only those oils that are identified as me[...]

If you are in an area of extreme cold, where the temperature falls below − 20°F ( − 29°C), it is recommended that you use either an SAE 5W-30 synthetic oil or an SAE 0W-30 oil. Both will provide easier cold starting and better protection for your engine at extremely low temperatures. Engine Oil Additives Do not add anything to your oil. The recommended oils with the starburst symbol that meet GM Standard GM6094M are all you will need for good performance and engine protection. Engine Oil Life System (Gasoline Engine) When to Change Engine Oil Your vehicle has a computer system that lets you know when to change the engine oil and filter. This is based on engine revolutions and engine t[...]

How to Reset the Engine Oil Life System The Engine Oil Life System calculates when to change your engine oil and filter based on vehicle use. Anytime your oil is changed, reset the system so it can calculate when the next oil change is required. If a situation occurs where you change your oil prior to a CHANGE ENGINE OIL message being turned on, reset the system. To reset the Engine Oil Life System, do the following: 1. Turn the ignition key to RUN with the engine of f. 2. Fully press and release the accelerator pedal three times within five seconds. If the OIL LIFE RESET message flashes for 10 seconds, the system is resetting. 3. Turn the key to LOCK. If the CHANGE ENGINE OIL message com[...]

Engine Air Cleaner/Filter (Gasoline Engines) If your vehicle has a diesel engine, see “Pickup Models” under “Engine Air Cleaner/Filter” in the DURAMAX ® Diesel Supplement for the correct inspection and replacement procedures. See Engine Compartment Overview on page 5-14 for the location of the engine air cleaner/filter and the air filter restriction indicator, if equipped. When to Inspect the Engine Air Cleaner/Filter If your vehicle is equipped with an air filter restriction indicator, it lets you know when the engine air cleaner/ filter needs to be replaced. On vehicles with a restriction indicator, you should inspect the air filter restriction indicator at every oil change a[...]

Replacing the Engine Air Cleaner/Filter and Resetting the Air Filter Restriction Indicator 1. Locate the air cleaner/filter assembly on the front corner of the engine compartment on the passenger’s side of the vehicle. 2. Loosen the screws on the cover of the housing and lift up the cover. 3. Remove the engine air cleaner/filter from the housing. Care should be taken to dislodge as little dirt as possible. 4. Clean the engine air cleaner/filter sealing surfaces and the housing. 5. Inspect or replace the engine air cleaner/filter. 6. Reinstall the cover and tighten the screws. 7. Reset the air filter restriction indicator, if equipped, by pressing the top button on the indicator. 5-26[...]

{ CAUTION: Operating the engine with the air cleaner/filter off can cause you or others to be burned. The air cleaner not only cleans the air; it helps to stop flames if the engine backfires. If it is not there and the engine backfires, you could be burned. Do not drive with it off, and be careful working on the engine with the air cleaner/filter off. Automatic Transmission Fluid (Except Allison Transmission ® ) When to Check and Change Automatic Transmission Fluid A good time to check your automatic transmission fluid level is when the engine oil is changed. Change the fluid and filter at the intervals listed in Additional Required Services (Gasoline Engine) on page 6-7 , and be su[...]

Get the vehicle warmed up by driving about 15 miles (24 km) when outside temperatures are above 50°F (10°C). If it is colder than 50°F (10°C), drive the vehicle in THIRD (3) until the engine temperature gage moves and then remains steady for 10 minutes. A cold fluid check can be made after the vehicle has been sitting for eight hours or more with the engine off, but this is used only as a reference. Let the engine run at idle for five minutes if outside temperatures are 50°F (10°C) or more. If it is colder than 50°F (10°C), you may have to idle the engine longer. Should the fluid level be low during this cold check, you must check the fluid hot before adding fluid. Checking the [...]

3. Check both sides of the dipstick, and read the lower level. The fluid level must be in the COLD area, below the cross-hatched area, for a cold check or in the HOT or cross-hatched area for a hot check. Be sure to keep the dipstick pointed down to get an accurate reading. 4. If the fluid level is in the acceptable range, push the dipstick back in all the way; then flip the handle down to lock the dipstick in place. Consistency of Readings Always check the fluid level at least twice using the procedure described previously. Consistency (repeatable readings) is important to maintaining proper fluid level. If inconsistent readings persist, check the transmission breather hose to be sure [...]

Automatic Transmission Fluid (Allison Transmission ® ) When to Check and Change Automatic Transmission Fluid A good time to check your automatic transmission fluid level is when the engine oil is changed. Change the fluid and filter at the intervals listed in Additional Required Services (Gasoline Engine) on page 6-7 , and be sure to use the transmission fluid listed in Recommended Fluids and Lubricants (Gasoline Engine) on page 6-14 . How to Check Automatic Transmission Fluid Because this operation can be a little diff icult, you may choose to have this done at the dealership service department. If you do it yourself, be sure to follow all the instructions here, or you could get a fals[...]

Then, without shutting off the engine, follow these steps: Cold Check Procedure The purpose of the cold check is to determine if the transmission has enough fluid to be operated safely until a hot check can be made. The fluid level rises as fluid temperature increases. Do not fill above the COLD CHECK band if the transmission fluid is below normal operating temperatures. 1. Pull out the dipstick and wipe it with a clean rag or paper towel. 2. Push it back in all the way, wait three seconds and then pull it back out again. 3. Check the fluid level reading. Repeat the check procedure to verify the reading. 4. If the fluid level is within the COLD CHECK band, the transmission may be oper[...]

Consistency of Readings Always check the fluid level at least twice using the procedures described previously. Consistency (repeatable readings) is important to maintaining proper fluid level. If inconsistent readings persist, check the transmission breather to be sure it is clean and unclogged. If readings are still inconsistent, contact your dealer. How to Add Automatic Transmission Fluid Refer to the Maintenance Schedule to determine what kind of transmission fluid to use. See Recommended Fluids and Lubricants (Gasoline Engine) on page 6-14 . Add fluid only after checking the transmission fluid while it is hot. A cold check is used only as a reference. If the fluid level is low, add[...]

How to Check Manual Transmission Fluid Because this operation can be a little diff icult, you may choose to have this done at the dealership service department. If you do it yourself, be sure to follow all the instructions here, or you could get a false reading. Notice: Too much or too little fluid can damage your transmission. Too much can mean that some of the fluid could come out and fall on hot engine part or exhaust system parts, starting a fire. Too little fluid could cause the transmission to overheat. Be sure to get an accurate reading if you check your transmission fluid. Check the fluid level only when your engine is off, the vehicle is parked on a level place, and the transm[...]

How to Add Manual Transmission Fluid Here is how to add fluid. Refer to the Maintenance Schedule to determine what kind of fluid to use. See Recommended Fluids and Lubricants (Gasoline Engine) on page 6-14 . 1. Remove the filler plug. 2. Add fluid at the filler plug hole. Add only enough fluid to bring the fluid level up to the bottom of the filler plug hole. 3. Install the filler plug. Be sure the plug is fully seated. Hydraulic Clutch The hydraulic clutch linkage in your vehicle is self-adjusting. The clutch master cylinder reservoir is filled with hydraulic clutch fluid. It is not necessary to regularly check clutch fluid unless you suspect there is a leak in the system. Addin[...]

How to Check and Add Fluid The proper fluid should be added if the level does not reach the bottom of the diaphragm when it is in place in the reservoir. See the instructions on the reservoir cap. Engine Coolant The cooling system in your vehicle is filled with DEX-COOL ® engine coolant. This coolant is designed to remain in your vehicle for five years or 150,000 miles (240 000 km), whichever occurs first, if you add only DEX-COOL ® extended life coolant. The following explains your cooling system and how to add coolant when it is low. If you have a problem with engine overheating, see Engine Overheating on page 5-37 . A 50/50 mixture of clean, drinkable water and DEX-COOL ® coolant w[...]

What to Use Use a mixture of one-half clean, drinkable water and one-half DEX-COOL ® coolant which will not damage aluminum parts. If you use this coolant mixture, you do not need to add anything else. { CAUTION: Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid such as alcohol, can boil before the proper coolant mixture will. Your vehicle’s coolant warning system is set for the proper coolant mixture. With plain water or the wrong mixture, your engine could get too hot but you would not get the overheat warning. Your engine could catch fire and you or others could be burned. Use a 50/50 mixture of clean, drinkable water and DEX-COOL ® co[...]

If your vehicle is equipped with a low coolant sensor and the LOW COOLANT LEVEL message comes on and stays on, it means you are low on engine coolant. See “LOW COOLANT LEVEL” under DIC Warnings and Messages on page 3-54 . Adding Coolant If you need more coolant, add the proper DEX-COOL ® coolant mixture at the surge tank, but only when the engine is cool. { CAUTION: You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol, and it will burn if the engine parts are hot enough. Do not spill coolant on a hot engine. When replacing the pressure cap, make sure it is hand-tight and fully seated. Coolant Surge Tank Pressure Cap Notice: If the pressure cap is [...]

If Steam Is Coming From Your Engine { CAUTION: Steam from an overheated engine can burn you badly, even if you just open the hood. Stay away from the engine if you see or hear steam coming from it. Just turn it off and get everyone away from the vehicle until it cools down. Wait until there is no sign of steam or coolant before you open the hood. If you keep driving when your engine is overheated, the liquids in it can catch fire. You or others could be badly burned. Stop your engine if it overheats, and get out of the vehicle until the engine is cool. See Overheated Engine Protection Operating Mode (V8 Engines Only) on page 5-40 for information on driving to a safe place in an emergency. N[...]

If you get the ENGINE COOLANT HOT message with no sign of steam, try this for a minute or so: 1. If your air conditioner is on, turn it of f. 2. Turn on your heater to full hot at the highest fan speed and open the windows as necessary. 3. If you are in a traf f ic jam, shift to NEUTRAL (N); otherwise, shift to the highest gear while driving — DRIVE (D) or THIRD (3). If you no longer have the overheat warning, you can drive. Just to be safe, drive slower for about 10 minutes. If the warning does not come back on, you can drive normally. If the warning continues, pull over, stop, park, and fast idle your vehicle right away. If there is still no sign of steam and your vehicle is equipped wit[...]

Overheated Engine Protection Operating Mode (V8 Engines Only) If an overheated engine condition exists and the REDUCED ENGINE POWER message is displayed, an overheat protection mode which alternates firing groups of cylinders helps prevent engine damage. In this mode, you will notice a loss in power and engine performance. This operating mode allows your vehicle to be driven to a safe place in an emergency. Driving extended miles (km) and/or towing a trailer in the overheat protection mode should be avoided. Notice: After driving in the overheated engine protection operating mode, to avoid engine damage, allow the engine to cool before attempting any repair. The engine oil will be severely [...]

A. Coolant Surge Tank B. Coolant Surge Tank Pressure Cap C. Engine Cooling Fan { CAUTION: An electric fan under the hood can start up and injure you even when the engine is not running. Keep hands, clothing and tools away from any underhood electric fan. If the coolant inside the coolant surge tank is boiling, do not do anything else until it cools down. The vehicle should be parked on a level surface. Check the coolant level after the system cools down. Some amount of coolant may be lost due to overheating. The coolant level should be at or above the FULL COLD mark. If it is not, you may have a leak at the pressure cap or in the radiator hoses, heater hoses, radiator, water pump, or somewhe[...]

{ CAUTION: Heater and radiator hoses, and other engine parts, can be very hot. Do not touch them. If you do, you can be burned. Do not run the engine if there is a leak. If you run the engine, it could lose all coolant. That could cause an engine fire, and you could be burned. Get any leak fixed before you drive the vehicle. If your vehicle is equipped with an electric engine cooling fan, check the coolant temperature gage. If the coolant temperature is approximately 232°F (111°C), the electric cooling fan should be running. If it is not, your vehicle needs service. Turn off the engine. If your vehicle is equipped with an engine-driven cooling fan, start the engine again and see if the f[...]

If no coolant is visible in the surge tank, add coolant as follows: { CAUTION: Steam and scalding liquids from a hot cooling system can blow out and burn you badly. They are under pressure, and if you turn the coolant surge tank pressure cap — even a little — they can come out at high speed. Never turn the cap when the cooling system, including the coolant surge tank pressure cap, is hot. Wait for the cooling system and coolant surge tank pressure cap to cool if you ever have to turn the pressure cap. { CAUTION: Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid such as alcohol, can boil before the proper coolant mixture will. Your vehicle?[...]

{ CAUTION: You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol and it will burn if the engine parts are hot enough. Do not spill coolant on a hot engine. 1. You can remove the coolant surge tank pressure cap when the cooling system, including the coolant surge tank pressure cap and upper radiator hose, is no longer hot. Turn the pressure cap slowly counterclockwise about one full turn. If you hear a hiss, wait for that to stop. A hiss means there is still some pressure left. 2. Then keep turning the pressure cap slowly, and remove it. 3. Fill the coolant surge tank with the proper mixture, to the FULL COLD mark. 5-44[...]

4. With the coolant surge tank pressure cap of f, start the engine and let it run until you can feel the upper radiator hose getting hot. Watch out for the engine cooling fan. By this time, the coolant level inside the coolant surge tank may be lower. If the level is lower, add more of the proper mixture to the coolant surge tank until the level reaches the FULL COLD mark. 5. Then replace the pressure cap. Be sure the pressure cap is hand-tight and fully seated. Engine Fan Noise If your vehicle is equipped with a clutched engine cooling fan, when the clutch is engaged, the fan spins faster to provide more air to cool the engine. In most everyday driving conditions, the fan is spinning slower[...]

Power Steering Fluid See Engine Compartment Overview on page 5-14 for reservoir location. When to Check Power Steering Fluid It is not necessary to regularly check power steering fluid unless you suspect there is a leak in the system or you hear an unusual noise. A fluid loss in this system could indicate a problem. Have the system inspected and repaired. How to Check Power Steering Fluid To check the power steering fluid, do the following: 1. Turn the key of f and let the engine compartment cool down. 2. Wipe the cap and the top of the reservoir clean. 3. Unscrew the cap and wipe the dipstick with a clean rag. 4. Replace the cap and completely tighten it. 5. Remove the cap again and look[...]

Windshield Washer Fluid What to Use When you need windshield washer fluid, be sure to read the manufacturer’s instructions before use. If you will be operating your vehicle in an area where the temperature may fall below freezing, use a fluid that has suff icient protection against freezing. Adding Washer Fluid Your vehicle has a low washer fluid message that comes on when the washer fluid is low. The message is displayed for 15 seconds at the start of each ignition cycle. When the CHECK WASHER FLUID message is displayed, you will need to add washer fluid to the windshield washer fluid reservoir. Open the cap with the washer symbol on it. Add washer fluid until the tank is full. See[...]

Brakes Brake Fluid Your brake master cylinder reservoir is filled with DOT-3 brake fluid. See Engine Compartment Overview on page 5-14 for the location of the reservoir. There are only two reasons why the brake fluid level in the reservoir might go down. The first is that the brake fluid goes down to an acceptable level during normal brake lining wear. When new linings are put in, the fluid level goes back up. The other reason is that fluid is leaking out of the brake system. If it is, you should have your brake system fixed, since a leak means that sooner or later your brakes will not work well, or will not work at all. So, it is not a good idea to top off your brake fluid. Adding [...]

Checking Brake Fluid You can check the brake fluid without taking off the cap. Just look at the brake fluid reservoir. The fluid level should be above MIN. If it is not, have your brake system checked to see if there is a leak. After work is done on the brake hydraulic system, make sure the level is above the MIN but not over the MAX mark. What to Add When you do need brake fluid, use only DOT-3 brake fluid. Use new brake fluid from a sealed container only. See Recommended Fluids and Lubricants (Gasoline Engine) on page 6-14 . Always clean the brake fluid reservoir cap and the area around the cap before removing it. This will help keep dirt from entering the reservoir. { CAUTION: With[...]

Brake Wear Your vehicle has front disc brakes and may have rear drum brakes or rear disc brakes. Disc brake pads have built-in wear indicators that make a high-pitched warning sound when the brake pads are worn and new pads are needed. The sound may come and go or be heard all the time your vehicle is moving, except when you are pushing on the brake pedal firmly. { CAUTION: The brake wear warning sound means that soon your brakes will not work well. That could lead to an accident. When you hear the brake wear warning sound, have your vehicle serviced. Notice: Continuing to drive with worn-out brake pads could result in costly brake repair. Some driving conditions or climates may cause a bra[...]

Replacing Brake System Parts The braking system on a vehicle is complex. Its many parts have to be of top quality and work well together if the vehicle is to have really good braking. Your vehicle was designed and tested with top-quality GM brake parts. When you replace parts of your braking system — for example, when your brake linings wear down and you need new ones put in — be sure you get new approved GM replacement parts. If you do not, your brakes may no longer work properly. For example, if someone puts in brake linings that are wrong for your vehicle, the balance between your front and rear brakes can change — for the worse. The braking performance you have come to expect can c[...]

Jump Starting If your vehicle’s battery (or batteries) has run down, you may want to use another vehicle and some jumper cables to start your vehicle. Be sure to use the following steps to do it safely. { CAUTION: Batteries can hurt you. They can be dangerous because: • They contain acid that can burn you. • They contain gas that can explode or ignite. • They contain enough electricity to burn you. If you do not follow these steps exactly, some or all of these things can hurt you. Notice: Ignoring these steps could result in costly damage to your vehicle that would not be covered by your warranty. Trying to start your vehicle by pushing or pulling it will not work, and it could damag[...]

3. Get the vehicles close enough so the jumper cables can reach, but be sure the vehicles are not touching each other. If they are, it could cause a ground connection you do not want. You would not be able to start your vehicle, and the bad grounding could damage the electrical systems. To avoid the possibility of the vehicles rolling, set the parking brake firmly on both vehicles involved in the jump start procedure. Put an automatic transmission in PARK (P) or a manual transmission in NEUTRAL before setting the parking brake. If you have a four-wheel-drive vehicle, be sure the transfer case is in a drive gear, not in NEUTRAL. Notice: If you leave your radio or other accessories on during [...]

{ CAUTION: Using a match near a battery can cause battery gas to explode. People have been hurt doing this, and some have been blinded. Use a flashlight if you need more light. Be sure the battery has enough water. You do not need to add water to the battery installed in your new vehicle. But if a battery has filler caps, be sure the right amount of fluid is there.

Also, if a vehicle has just been driven before checking the fluid level, it may appear lower than normal because fluid has traveled out along the axle tubes and has not drained back to the sump area. Therefore, a reading taken five minutes after the vehicle has been driven will appear to have a lower fluid level than a vehicle that has been stationary for an hour or two. Remember that the rear axle assembly must be supported to get a true reading. How to Check Lubricant To get an accurate reading, the vehicle should be on a level surface. • The proper level for the 1500 Series is from 5/8 inch to 1 5/8 inch (15 mm to 40 mm) below the bottom of the filler plug hole. • The proper leve[...]

UTQGS (Uniform Tire Quality Grading Standards): A tire information system that provides consumers with ratings for a tire’s traction, temperature, and treadwear. Rati[...]

Inflation - Tire Pressure Tires need the correct amount of air pressure to operate effectively. Notice: Do not let anyone tell you that under-inflation or over-inflation is all right. It is not. If your tires do not have enough air (under-inflation), you can get the following: • Too much flexing • Too much heat • Tire overloading • Premature or irregular wear • Poor handling • Reduced fuel economy If your tires have too much air (over-inflation), you can get the following: • Unusual wear • Poor handling • Rough ride • Needless damage from road hazards A Tire and Loading Information label is attached to the vehicle’s center pillar (B-pillar), below the driver’s d[...]

Remove the valve cap from the tire valve stem. Press the tire gage firmly onto the valve to get a pressure measurement. If the cold tire inflation pressure matches the recommended pressure on the Tire and Loading Information label, no further adjustment is necessary. If the inflation pressure is low, add air until you reach the recommended amount. If you overfill the tire, release air by pushing on the metal stem in the center of the tire valve. Recheck the tire pressure with the tire gage. Be sure to put the valve caps back on the valve stems. They help prevent leaks by keeping out dirt and moisture. High Speed Operation (SS Silverado) { CAUTION: Driving at high speeds, 100 mph (160 km/[...]

Dual Tire Operation When the vehicle is new, or whenever a wheel, wheel bolt or wheel nut is replaced, check the wheel nut torque after 100, 1,000 and 6,000 miles (160, 1 600 and 10 000 km) of driving. For proper torque and wheel nut tightening information, see Removing the Spare Tire and Tools on page 5-94 . The outer tire on a dual wheel setup generally wears faster than the inner tire. Your tires will wear more evenly and last longer if you rotate the tires periodically, see Tire Inspection and Rotation on page 5-82 . Also see Scheduled Maintenance (Gasoline Engine) on page 6-4 . { CAUTION: If you operate your vehicle with a tire that is badly underinflated, the tire can overheat. An ove[...]

If your vehicle has single rear wheels and the tread design for your front tires is the same as your rear tires, use the rotation pattern shown here when rotating your tires. If your vehicle has dual rear wheels and the tread design for your front tires is the same as your rear tires, always use one of the correct rotation patterns shown here when rotating your tires. 5-83[...]

If your vehicle has dual rear wheels and the tread design for the front tires is different from the dual rear tires, always use the correct rotation pattern shown here when rotating your tires. The dual tires are rotated as a pair, and the inside rear tires become the outside rear tires. When you install dual wheels, be sure the vent holes in the inner and outer wheels on each side are lined up. After the tires have been rotated, adjust the front and rear inflation pressures as shown on the Tire and Loading Information label. See Loading Your Vehicle on page 4-48 . Make certain that all wheel nuts are properly tightened. See “Wheel Nut Torque” under Capacities and Specifications on pag[...]

When It Is Time for New Tires One way to tell when it is time for new tires is to check the treadwear indicators, which will appear when your tires have only 1/16 inch (1.6 mm) or less of tread remaining. Some commercial truck tires may not have treadwear indicators. You need a new tire if any of the following statements are true: • You can see the indicators at three or more places around the tire. • You can see cord or fabric showing through the tire’s rubber. • The tread or sidewall is cracked, cut or snagged deep enough to show cord or fabric. • The tire has a bump, bulge, or split. • The tire has a puncture, cut, or other damage that cannot be repaired well because of the si[...]

Buying New Tires GM has developed and matched specific tires for your vehicle. The original equipment tires installed on your vehicle, when it was new, were designed to meet General Motors Tire Performance Criteria Specification (TPC spec) system rating. If you need replacement tires, GM strongly recommends that you get tires with the same TPC Spec rating. This way, your vehicle will continue to have tires that are designed to give the same performance and vehicle safety, during normal use, as the original tires. GM’s exclusive TPC Spec system considers over a dozen critical specifications that impact the overall performance of your vehicle, including brake system performance, ride and [...]

{ CAUTION: If you use bias-ply tires on your vehicle, the wheel rim flanges could develop cracks after many miles of driving. A tire and/or wheel could fail suddenly, causing a crash. Use only radial-ply tires with the wheels on your vehicle. If you must replace your vehicle’s tires with those that do not have a TPC Spec number, make sure they are the same size, load range, speed rating, and construction type (radial and bias-belted tires) as your vehicle’s original tires. Your vehicle’s original equipment tires are listed on the Tire and Loading Information Label. This label is attached to the vehicle’s center pillar (B-pillar). See Loading Your Vehicle on page 4-48 , for more info[...]

Uniform Tire Quality Grading Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width. For example: Treadwear 200 Traction AA Temperature A The following information relates to the system developed by the United States National Highway Traff ic Safety Administration, which grades tires by treadwear, traction and temperature performance. (This applies only to vehicles sold in the United States.) The grades are molded on the sidewalls of most passenger car tires. The Uniform Tire Quality Grading system does not apply to deep tread, winter-type snow tires, space-saver or temporary use spare tires, tires with nominal rim diameters of 10 t[...]

Temperature – A, B, C The temperature grades are A (the highest), B, and C, representing the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law. Warning: The tempe[...]

Each new wheel should have the same load-carrying capacity, diameter, width, offset and be mounted the same way as the one it replaces. If you need to replace any of your wheels, wheel bolts or wheel nuts, replace them only with new GM original equipment parts. This way, you will be sure to have the right wheel, wheel bolts and wheel nuts for your vehicle. { CAUTION: Using the wrong replacement wheels, wheel bolts, or wheel nuts on your vehicle can be dangerous. It could affect the braking and handling of your vehicle, make your tires lose air and make you lose control. You could have a collision in which you or others could be injured. Always use the correct wheel, wheel bolts and wheel nut[...]

Tire Chains { CAUTION: If your vehicle has dual wheels or P265/75R16, LT265/75R16, P265/70R17 or P275/55R20 size tires, do not use tire chains. They can damage your vehicle because there is not enough clearance. Tire chains used on a vehicle without the proper amount of clearance can cause damage to the brakes, suspension or other vehicle parts. The area damaged by the tire chains could cause you to lose control of your vehicle and you or others may be injured in a crash. Use another type of traction device only if its manufacturer recommends it for use on your vehicle and tire size combination and road conditions. Follow that manufacturer’s instructions. To help avoid damage to your vehic[...]

If a Tire Goes Flat It is unusual for a tire to blowout while you are driving, especially if you maintain your vehicle’s tires properly. If air goes out of a tire, it is much more likely to leak out slowly. But if you should ever have a blowout, here are a few tips about what to expect and what to do: If a front tire fails, the flat tire will create a drag that pulls the vehicle toward that side. Take your foot off the accelerator pedal and grip the steering wheel firmly. Steer to maintain lane position, and then gently brake to a stop well out of the traff ic lane. A rear blowout, particularly on a curve, acts much like a skid and may require the same correction you would use in a skid.[...]

{ CAUTION: Changing a tire can be dangerous. The vehicle can slip off the jack and roll over or fall on you or other people. You and they could be badly injured or even killed. Find a level place to change your tire. To help prevent the vehicle from moving: 1. Set the parking brake firmly. 2. Put an automatic transmission shift lever in PARK (P), or shift a manual transmission to FIRST (1) or REVERSE (R). 3. If you have a four-wheel-drive vehicle, be sure the transfer case is in a drive gear – not in NEUTRAL. 4. Turn of f the engine and do not restart while the vehicle is raised. 5. Do not allow passengers to remain in the vehicle. CAUTION: (Continued) CAUTION: (Continued) To be even more[...]

See Inflation - Tire Pressure on page 5-80 and Loading Your Vehicle on page 4-48 for information regarding proper tire inflation and loading your vehicle. For instruction on how to remove, install or store a spare tire, see Removing the Flat Tire and Installing the Spare Tire on page 5-98 and Storing a Flat or Spare Tire and Tools on page 5-110 .

Lighter colored interiors may require more frequent cleaning. Use care because newspapers and garments that transfer color to your home furnishings may also transfer color to your vehicle’s interior. When cleaning your vehicle’s interior, only use cleaners specifically designed for the surfaces being cleaned. Permanent damage may result from using cleaners on surfaces for which they were not intended. Use glass cleaner only on glass. Remove any accidental over-spray from other surfaces immediately. To prevent over-spray, apply cleaner directly to the cleaning cloth. Notice: If you use abrasive cleaners when cleaning glass surfaces on your vehicle, you could scratch the glass. When clean[...]

Fabric/Carpet Use a vacuum cleaner with a soft brush attachment frequently to remove dust and loose dirt. A canister vacuum with a beater bar in the nozzle may only be used on floor carpet and carpeted floor mats. For soils, always try to remove them first with plain water or club soda. Before cleaning, gently remove as much of the soil as possible using one of the following techniques: • For liquids: gently blot the remaining soil with a paper towel. Allow the soil to absorb into the paper towel until no more can be removed. • For solid dry soils: remove as much as possible and then vacuum. To clean, use the following instructions: 1. Saturate a lint-free, clean white cloth with wate[...]

Instrument Panel, Vinyl, and Other Plastic Surfaces A soft cloth dampened with water may be used to remove dust. If a more thorough cleaning is necessary, a clean soft cloth dampened with a mild soap solution can be used to gently remove dust and dirt. Never use spot lifters or removers on plastic surfaces. Many commercial cleaners and coatings that are sold to preserve and protect soft plastic surfaces may permanently change the appearance and feel of your interior and are not recommended. Do not use silicone or wax-based products, or those containing organic solvents to clean your vehicle’s interior because they can alter the appearance by increasing the gloss in a non-uniform manner. So[...]

Washing Your Vehicle The paint finish on the vehicle provides beauty, depth of color, gloss retention, and durability. The best way to preserve the vehicle’s finish is to keep it clean by washing it often with lukewarm or cold water. Do not wash the vehicle in the direct rays of the sun. Use a car washing soap. Do not use strong soaps or chemical detergents. Be sure to rinse the vehicle well, removing all soap residue completely. GM-approved cleaning products can be obtained from your dealer. See Vehicle Care/Appearance Materials on page 5-121 . Do not use cleaning agents that are petroleum based, or that contain acid or abrasives. All cleaning agents should be flushed promptly and not [...]

Protecting Exterior Bright Metal Parts Bright metal parts should be cleaned regularly to keep their luster. Washing with water is all that is usually needed. However, you may use chrome polish on chrome or stainless steel trim, if necessary. Use special care with aluminum trim. To avoid damaging protective trim, never use auto or chrome polish, steam or caustic soap to clean aluminum. A coating of wax, rubbed to high polish, is recommended for all bright metal parts. Windshield and Wiper Blades If the windshield is not clear after using the windshield washer, or if the wiper blade chatters when running, wax, sap, or other material may be on the blade or windshield. Clean the outside of the w[...]

Notice: If you drive your vehicle through an automatic car wash that has silicone carbide tire cleaning brushes, you could damage the aluminum or chrome-plated wheels. The repairs would not be covered by your warranty. Never drive a vehicle equipped with aluminum or chrome-plated wheels through an automatic car wash that uses silicone carbide tire cleaning brushes. Do not take your vehicle through an automatic car wash that has silicone carbide tire cleaning brushes. These brushes can also damage the surface of these wheels. Tires To clean the tires, use a stiff brush with tire cleaner. Notice: Using petroleum-based tire dressing products on your vehicle may damage the paint finish and/or t[...]

Chemical Paint Spotting Some weather and atmospheric conditions can create a chemical fallout. Airborne pollutants can fall upon and attack painted surfaces on the vehicle. This damage can take two forms: blotchy, ring-shaped discolorations, and small, irregular dark spots etched into the paint surface. Although no defect in the paint job causes this, GM will repair, at no charge to the owner, the surfaces of new vehicles damaged by this fallout condition within 12 months or 12,000 miles (20 000 km) of purchase, whichever occurs first.

Power Windows and Other Power Options Circuit breakers protect the power windows and other power accessories. When the current load is too heavy, the circuit breaker opens and closes, protecting the circuit until the problem is fixed or goes away. Fuses and Circuit Breakers The wiring circuits in your vehicle are protected from short circuits by a combination of fuses, circuit breakers and fusible thermal links. This greatly reduces the chance of fires caused by electrical problems. Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure you replace a bad fuse with a new one of the identical size and rating. If you ever have a problem on [...]

Using the Maintenance Schedule We at General Motors want to help you keep your vehicle in good working condition. But we do not know exactly how you will drive it. You may drive very short distances only a few times a week. Or you may drive long distances all the time in very hot, dusty weather. You may use your vehicle in making deliveries. Or you may drive it to work, to do errands, or in many other ways. Because of all the different ways people use their vehicles, maintenance needs vary. You may need more frequent checks and replacements. So please read the following and note how you drive. If you have any questions on how to keep your vehicle in good condition, see your GM Goodwrench ® [...]

If an Accident Occurs Here is what to do if you are involved in an accident. • Try to relax and then check to make sure you are all right.

Do not leave the scene of an accident until all matters have been taken care of. Move your vehicle only if its position puts you in danger or you are instructed to move it by a police off icer. • Give only the necessary and requested information to police and other parties involved in the accident. Do not discuss your personal condition, mental frame of mind, or anything unrelated to the accident. This[...]

Managing the Vehicle Damage Repair Process In the event that your vehicle requires damage repairs, GM recommends that you take an active role in its repair.

Specify to the facility that any required replacement collision parts be original equipment parts, either new Genuine GM parts or recycled original GM parts. Remember, recycled parts will not be covered by your GM vehicle warranty. Insurance pays the bill for the repair, but you must live with the repair. Depending on your policy limits, your insurance company may initially value the repair using aftermarket parts. Discuss this with y[...]
