Description & Operation: Notes
WARNING: This page is about a different car, the 2002 Buick Park Avenue. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Accidental air bag deployment is possible. Personal injury may result. Read and follow all WARNINGS and Service Precautions before working on air bag system or related components.
Supplemental Inflatable Restraint (SIR) system is designed to supplement protection provided by driver-side and passenger-side seat belts. A frontal collision of sufficient force will cause Sensing and Diagnostic Module (SDM) to deploy driver-side and passenger-side air bags. A side collision of sufficient force will cause SDM to deploy side impact air bag on side of impact. Steering column and knee bolsters also absorb collision energy.
SIR system consists of SDM, driver-side and passenger-side air bag modules, driver and passenger side impact air bag modules, driver-side and passenger-side Side Impact Sensors (SIS), SIR coil assembly and AIR BAG warning light.
