Air Bag Systems: Description and Operation

AIR BAG AND SAFETY BELT PRETENSIONER SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

The air bag supplemental restraint system (SRS) is designed to provide increased collision protection for front seat and second row outboard occupants in addition to that provided by the 3-point safety belt system. Safety belt use is necessary to obtain the best occupant protection and to receive the full advantage of the SRS.

This vehicle line contains dual-stage deployment (advanced restraint system) driver and front passenger air bag modules. These vehicles are also equipped with safety canopy modules and seat side air bag modules. A unique restraints control module (RCM) is used on these vehicles which will detect a potential rollover condition. In addition, a front impact severity sensor located in the front center area behind the grille, 4 side impact sensors (first row located in each front door, second row mounted at or near each C-pillar), a seat position sensor is mounted to the driver seat and a usage detection switch is added to the front driver and passenger outboard buckles.
