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. The SRS will also provide increased collision protection for the rear occupants when equipped with optional safety canopy modules. 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 canopies that deploy from the A-pillar to the C-pillar upon a side impact or if a rollover condition is detected. Vehicles equipped with safety canopy modules are also equipped with 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 is mounted to the radiator support bracket, 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.
Safety canopy modules deploy from the headliner, protecting the first and second row outboard occupants during a side impact or if a rollover condition is detected. Seat side air bag modules deploy from the outboard front seat backrest upon a side impact.
Before servicing the SRS, the system must be depowered. Refer to Supplemental Restraint System (SRS) Depowering and Repowering.
