Description & Operation: Notes

WARNING: This page is about a different car, the 2002 Chevrolet Prizm. 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 AIR BAG SAFETY 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 up to 30 degrees off center line of vehicle will deploy driver-side and passenger-side air bags. A side collision of sufficient force will deploy the side impact air bag module on side of collision. Steering column and knee bolsters also absorb collision energy.

SIR system consists of Sensing and Diagnostic Module (SDM), driver-side and passenger-side air bag modules, left and right side impact air bag modules, seat belt pretensioners, SIR coil assembly, driver-side and passenger-side front end discriminating sensors, side impact sensors and AIR BAG warning light in instrument cluster.
