    REMOVAL & INSTALLATION




    WARNING
    If equipped with the air cushion restraint system, do not attempt any service which would require removal of the steering wheel, column, or dashboard. Any service procedures involving these components should only be performed by a professional. Do not attempt any other service until the ignition switch is turned to the LOCK position and the negative battery cable is disconnected and the end taped. This procedure must be followed to prevent accidental deployment of the system which could result in personal injury and/or damage to the systems components. In addition, care must be exercised to never bump or strike the bumper impulse detector in a manner which could cause inadvertent deployment or improper operation of the system.
