The steering column components perform functions other than steering. The following components on the steering column perform the described functions:

    • The column.
        The column absorbs energy. The column will compress in a front end collision in order to lessen the chance of injury to the driver.
    • The ignition switch and the lock mount on the column.
        The ignition and the steering operations will lock in order to inhibit the theft of the vehicle with the column mounted lock.
    • The multifunction lever.
        The multifunction lever provides control of the following components:
       - The headlamp high-beams
       - The cruise control
       - The windshield wiper and the washer

The column is easily disassembled and reassembled. Use the specified screws, bolts and nuts in order to ensure that the energy absorbing action occurs. Take special care in handling the column when the column is removed from the vehicle.

The plastic fasteners that maintain the column rigidity may shear or loosen if the following conditions exist:

  1. Use of a steering wheel puller other than the recommended puller
  2. A sharp striking on the end of the steering shaft or the shift lever
  3. Something is leaning on the column
  4. A dropped column
