REMOVAL & INSTALLATION




CAUTION
Some vehicles are equipped with the Supplemental Inflatable Restraint (SIR) system, which uses an air bag. Whenever working near any of the SIR components, such as the impact sensors, the air bag module, steering column and instrument panel, disable the SIR system, as described in Chassis Electrical . Failure to follow safety and disabling procedures could result in accidental air bag deployment, unnecessary SIR system repairs, and above all, possible personal injury.

CAUTION
When carrying a live air bag, make sure the bag and trim cover and pointed away from the body. In the unlikely event of an accidental deployment, the bag will then deploy with minimal chance of injury. In addition, when placing a live air bag on a bench or other surface, always face the bag and trim cover up, away from the surface. This will reduce the chance of personal injury if it is accidentally deployed.
