The locking, energy-absorbing column (20) includes the following three features in addition to the steering function:

    • In a front-end collision, the energy-absorbing column is designed to collapse. This action minimizes the possibility of driver injury.
    • The steering column lock and ignition cylinder are mounted on the column.
    • When locked, the column-mounted lock prevents the operation of both the ignition and steering. This action acts as a theft deterrent.

The turn signal controls the turn signals.

The headlamp dimmer switch controls the headlamp high beam.

The windshield washer and wiper lever (16) controls the windshield washer and wipers.

The cruise control actuator controls the cruise control, if equipped.

In order to ensure energy-absorbing action, complete the following steps:

    • Use only specified bolts/screws and nuts.
    • Tighten the bolts/screws and nuts to the specified torque.
    • Apply a thin coat of lithium grease to all friction points during reassembly.

Handle the column with care when removing the column.

    • Do not use a steering wheel puller other than the one recommended.
    • Do not hit the end of the steering gear coupling shaft (26) sharply.
    • Do not lean on the column.
    • Do not drop the column.

Disregarding the above suggestions could shear or loosen the plastic fasteners that keep the column rigid.
