1. Disconnect the negative battery cable.

CAUTION
When carrying a live air bag, make sure the bag and trim cover are 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 the trim cover up, away from the surface. This will reduce the chance of personal injury if it is accidently deployed.

A. Loosen the bolts or screws from the back of the steering wheel, using the proper Torx  driver, until the inflatable restraint module can be released from the steering wheel.
