Removal Procedure

    Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component.

Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.
