SIR System Overview
The supplemental inflatable restraint (SIR) system supplements the protection offered by the occupants Seat Belt System (2). The SIR system may contain several inflator modules located throughout the vehicle, i.e. steering wheel module (1), instrument panel module (1), or roof rail modules (1). In addition to inflator modules, the vehicle may contain seat belt pretensioners (2) that tighten the seat belt in the event of a collision, thus reducing the distance between the occupant and the seat belt when an inflator module is deployed. Each inflator module has a deployment loop that is controlled by the inflatable restraint sensing and diagnostic module (SDM) mounted inside the vehicle. The SDM determines the severity of a collision with the assistance of various sensor inputs located at strategic points on the vehicle. When the SDM detects a collision, it will process the information provided by the sensors to further support air bag or pretensioner deployment. The SDM will deploy the frontal air bags and pretensioners if it detects a collision of sufficient force. If the force of the impact is not sufficient to warrant inflator module deployment, the SDM may still deploy the seat belt pretensioners. The SDM performs continuous diagnostic monitoring of the SIR system electrical components. Upon detection of a circuit malfunction, the SDM will set a DTC and inform the driver by illuminating the AIR BAG indicator. The steering column (3) and knee bolsters (3) are designed to absorb energy and compress during frontal collisions in order to limit leg movement and decrease the chance of injury to the driver and passenger.
If the Vehicle Is Stuck
Slowly and cautiously spin the wheels to free the vehicle when stuck in sand,
mud, ice, or snow.
If stuck too severely for the traction system to free the vehicle, turn the traction
system off and use the rocking method.
WARNING
If the vehicle's tires spin at high speed, they can explode, ...

Warning Lights, Gauges, and Indicator
Warning lights and gauges can signal that something is wrong before it becomes
serious enough to cause an expensive repair or replacement. Paying attention to
the warning lights and gauges could prevent injury.
Warning lights come on when there could be a problem with a vehicle function.
