The locking energy-absorbing steering column includes the following three functions in addition to the steering function:

    • In a front-end collision, the column is designed to collapse in order to minimize driver injury.
    • The ignition switch, the steering column lock, and the ignition cylinder are column mounted, allowing the steering wheel and the ignition to be locked, minimizing the chance of vehicle theft.
    • The steering column levers control the turn signal, the headlamp switch, the headlamp dimmer switch, and the windshield wiper washer switch.

In order to ensure the energy-absorbing action, use only the specified bolts and nuts and tighten to the specified torque. Apply a thin layer of grease to all friction points during assembly. Carefully handle the column during removal. Using a steering wheel puller other than the recommended, or dropping/striking/leaning on the column, can shear or loosen the plastic fasteners that keep the column rigid.
