STEERING COLUMN
(Left–Hand Drive Shown, Right–Hand Dirve
Similar)
Important : Remove the steering column only if the follow-
ing conditions exist:
S The steering column requires replacement.
S The steering and the ignition lock housing require
replacement.
S 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. Drop-
ping the column assembly on its end or hammering the
end of the steering shaft can collapse the steering shaft or
loosen the plastic injections which maintain column rigid-
ity. Leaning on the column can cause it to bend or deform.
Any of the above damage can impair the column’s collaps-
ible 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
CAUTION : To ensure the energy–absorbing action of
the steering column, it is important to use only the
specified screws, bolts, and nuts, tightened to the
specified torque.
In addition to the steering function, the steering column
provides safety and security.
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 col-
umn, 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.The tilt steering column uses telescopic function to allow
the steering wheel to tilt up and down in and out. This en-
ables the driver to adjust the steering wheel to a comfort-
able position.
Notice : Apply a thin coat of lithium grease to all friction
points when reassembling.
The column may be disassembled and reassembled easi-
ly.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 ve-
hicle.
An internal switch in the ignition lock cylinder supplies bat-
tery voltage to the reminder chime module when all of the
following conditions are true:
S The key is in the ignition switch.
S The ignition is OFF.
S The driver’s door is open.
For information on removal and installation of the reminder
chime module, refer to Section 9E, Instrumentation/Driver
Information.
