OVERVIEW

WARNING: All pyrotechnic devices are dangerous. Before performing any procedures on any pyrotechnic device, read all information contained within the Service Information section of this product. Refer to: General Service Information (Description and Operation).
The SRS (supplemental restraint system) provides additional protection for vehicle occupants in certain impact conditions by selective activation of twin stage driver and passenger air bags, side air bags, side air curtains and front safety belt pretensioners. Operation of the system is controlled by a RCM (restraints control module).
The RCM (restraints control module) receives inputs from various sensors around the vehicle to determine which devices, if any, should be activated during an accident. The inputs include those from an occupant monitoring system for the front passenger seat, front and side impact sensors and side pressure sensors.
In all markets except NAS, a PAD (passenger air bag deactivation) switch is a dealer fit option that allows the passenger air bag to be disabled.
The activation status of the passenger air bag is given by an indicator on the overhead console. The status of the SRS (supplemental restraint system) is given by an air bag warning indicator in the instrument cluster.
