Airbag System Questions and Answers About Airbags and Specialty Law Enforcement V ehicles Q: Can equipment such as radar devices, video cameras, and radio trees be mounted in a specialty vehicle equipped with a right front passenger's frontal airbag? A: Y es, but care must be taken to properly mount the equipment outside of the airbag “ deployment zone. ” Q: What is the airbag “ deployment zone ” ? A: The term “ deployment zone ” describes the space an airbag takes up when fully inflated. Airbags need room to work properly , and anything in the “ deployment zone ” — such as improperly mounted equipment — can greatly affect the performance of the airbag. { W ARNING: A[...]

W ARNING: (Continued) airbag could prevent the airbag from operating properly . If this ever happens, the airbag would not be able to protect occupants the way it was designed to. T o help prevent injury and to allow the airbag to perform as it was designed, do not mount equipment inside the airbag deployment zone. Q: How can I identify the airbag “ deployment zone ” in my vehicle? A: See Airbag Deployment Diagrams on page 2 ‑ 6 for more information. The diagrams provide the approximate dimensions of the “ deployment zones ” for your specialty vehicle. Before doing any service work, including the installation of any equipment, consult the appropriate service manual. Q: Is it possib[...]

Q: Can the installation of push bumpers on the front end of the vehicle affect the deployment of the airbag? A: Y es, particularly if the push bumper significantly changes the front structure of the vehicle. However, GM conducts analysis on various push bumper configurations to verify effectiveness of the sensing performance system with minor changes in the front structure of the vehicle which may occur from the addition of a push bumper . Q: Is there anything I might add to the exterior of the vehicle that could keep the airbags from working properly? A: Y es. If you add things that change your vehicle's frame, bumper system, height, front end or side sheet metal, they may keep the air[...]

Notices for Customer-Installed Equipment Read the following notices before installing equipment on your specialty vehicle. Notice: GM-approved service procedures must be followed to remove and reinstall the instrument panel to the pad in order to ensure proper airbag deployment. Notice: Do not mount equipment on the passenger side of the instrument panel top pad deployment zone. Equipment should not be mounted on or around the passenger airbag opening because of a deploying airbag. T o allow the airbag to perform as it was designed, do not mount equipment inside the airbag deployment zone. Notice: Y our police vehicle may have optional roof-rail airbags. Do not mount a security barrier such [...]
