Description & Operation: Notes

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2002 GMC Sierra, 2002 GMC Cab & Chassis Sierra, 2002 GMC C3500 HD, 2002 Chevrolet Silverado, and 2002 Chevrolet Cab & Chassis Silverado. 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. To avoid accidental air bag deployment or injury, read and carefully follow all WARNINGS and AIR BAG SAFETY PRECAUTIONS .

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 deploy driver-side and passenger-side air bags modules. 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, passenger-side air bag disable switch, SIR coil assembly and AIR BAG warning light. A front end discriminating sensor is used 1500 and 2500 series trucks. An Electronic Frontal Sensor (EFS) is used on 3500 series trucks.
