3C1-2 AIR BAG STEERING WHEEL AND COLUMN
GENERAL DESCRIPTION
This double tube type steering column has the following three important features in addition to the steering function:

The column is energy absorbing, designed to compress in a front-end collision.

The ignition switch and lock are mounted conveniently on this column.

With the column mounted lock, the ignition and steering operations can be locked to inhibit theft of the vehicle.
To insure the energy absorbing action, it is important that only the specified screws, bolts, and nuts be used as
designated and that they are tightened to the specified torque. When the column assembly is removed from the
vehicle, special care must be taken in handling it. Use of a steering wheel puller other than the one recommended
in this manual or a sharp blow on the end of the steering shaft, leaning on the assembly, or dropping the assembly
could shear the plastic shear pins which maintain column length and position.
The driver air bag (inflator) module is one of the supplemental restraint (air bag) system components and is
mounted to the center of the steering wheel. During certain frontal crashes, the air bag system supplements the
restraint of the driver's and passenger's seat belts by deploying the air bags. The air bag (inflator) module should
be handled with care to prevent accidental deployment. When servicing, be sure to observe all WARNINGS in this
section. Refer to ªSERVICE PRECAUTIONSº in Section 10B.

INSPECTION
WARNING:
Never disassemble air bag (inflator) module or measure its
resistance. Otherwise, personal injury may result.
CAUTION:
If air bag (inflator) module was dropped from a height of
90 cm (3 ft) or more, it should be replaced.
Check air bag (inflator) module visually and if any of the following
is found, replace it with a new one.

Air bag being deployed.

Trim cover (pad surface) being cracked.

Wire harness or connector being damaged.

Air bag (inflator) module being damaged or having been exposed
to strong impact (dropped).

INSTALLATION
1) Check that vehicle's front tires are at straight-ahead position and
contact coil is centered. Refer to ªCENTERING CONTACT
COILº in this section.

steering wheel. If steering wheel has been installed with-
out these conditions, contact coil will break when steer-
ing wheel is turned.
2) Install steering wheel to steering shaft with 2 lugs on contact coil
fitted in two grooves in the back of steering wheel and also align-
ing marks on steering wheel and steering shaft.
3) Tighten steering shaft nut to specified torque.
Tightening Torque
(a): 33 N
.m (3.3 kg-m, 23.5 lb-ft)
4) Install driver air bag (inflator) module to steering wheel. Refer to
ªDRIVER AIR BAG (INFLATOR) MODULEº in this section.
CONTACT COIL AND COMBINATION SWITCH
ASSEMBLY
CAUTION:
Do not turn contact coil (on combination switch) more than
allowable number of turns (about two and a half turns from
the center position clockwise or counterclockwise respec-
tively), or coil will break.
REMOVAL
1) Remove steering wheel from steering column. Refer to
ªSTEERING WHEELº in this section.
2) Remove steering column hole cover.
3) Remove steering column cover screws (3 pieces).
4) Separate upper cover and lower cover, then remove them.
5) Disconnect all connectors for contact coil and combination
switch assembly.

INSPECTION
Check to make sure that the following:

Steering column moves smoothly when adjustable steering col-
umn release lever is at lower position (i.e., steering column is not
locked).

Steering column is fixed securely when adjustable steering col-
umn release lever is at upper position (i.e., steering column is
locked).

GENERAL DESCRIPTION
This automatic transmission is a full automatic type with 3-speed plus overdrive (O / D).
The torque converter is a 3-element, 1-step and 2-phase type and is equipped with an electronically controlled
lock-up mechanism. The gear shift device consists of 3 sets of planetary gear units, 3 disc type clutches, 4 disc
type brakes and 3 one-way clutches. The gear shift is done by selecting one of 6 positions (ªPº, ªRº, ªNº, ªDº, ª2º
and ªLº) by means of the select lever installed on the floor. On the shift knob, there is an overdrive (O / D) cut switch
which allows shift-up to the overdrive mode (except at 4L) and shift-down from the overdrive mode. Also, by using
the P / N change switch located on the console box, it is possible to select the gear change timing of 2 modes, nor-
mal and power.
