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.
