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 bag modules and seat belt pretensioners. Steering column and knee bolsters also absorb collision energy.

SIR system consists of Sensing and Diagnostic Module (SDM), driver-side and passenger-side dual stage (light-duty) or single stage (heavy-duty) air bag modules, driver-side and passenger-side seat belt pretensioners, driver and front passenger Seat Position Switches (SPS), front end discriminating sensor, SIR coil assembly, passenger-side air bag module disable switch and AIR BAG warning light.
