SECTION 6E

STEERING WHEEL AND COLUMN

Caution : Disconnect the negative battery cable before removing or installing any electrical unit or when a tool or equipment could easily come in contact with exposed electrical terminals. Disconnecting this cable will help prevent personal injury and damage to the vehicle. The ignition must also be in B unless otherwise noted.

DESCRIPTION AND OPERATION

STEERING WHEEL AND COLUMN

In addition to the steering function, the steering column provides safety and security.

Caution : To ensure energy-absorbing action, it is important to use only the specified screws, bolts, and nuts, tightened to the specified torque.

The energy-absorbing column is designed to compress in a front-end collision to lessen the chance of driver injury.
The ignition switch and the lock are mounted on the column, allowing the ignition and steering operations to be locked to inhibit theft of the car.
The column levers trigger the turn signals, the headlight beams, and the windshield washer and wipers.

Notice : Apply a thin coat of lithium grease to all friction points when reassembling to ensure proper operation.

The column may be easily disassembled and assembled.
