Steering Column

Important : Remove the steering column only if:

Another operation requires the removal of the steering column.

Notice : The steering column is extremely susceptible to damage after it has been removed from the vehicle. Dropping the column assembly on its end or hammering the end of the steering shaft can collapse the steering shaft or loosen plastic injections which maintain column rigidity. Leaning on the column can cause it to bend or deform. Any of the above damage can impair the column's collapsible design. If it is necessary to remove the steering wheel, use only the specified steering wheel puller.

GENERAL DESCRIPTION AND SYSTEM 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 prevent theft of the car.

The column levers trigger the turn signals, the headlight beams, and the windshield washer and wipers.

A tilt steering column uses a spherical joint to allow the steering wheel to tilt up and down. This enables the driver to adjust the steering wheel to a comfortable driving position.

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.

Ignition Key Reminder

The ignition key reminder alerts the driver that the key is still in the ignition when the driver attempts to exit the vehicle.

An internal switch in the ignition lock cylinder supplies battery voltage to the smart junction box when all of the following conditions are true:

The key is in the ignition switch.
The ignition is OFF.
The driver's door is open.

For information on removal and installation of the smart junction box, refer to Section 9E, Instrumentation/Driver Information.
