For vehicles equipped with Supplemental Restraint (Air Bag) System :
Service on and around the air bag system components or wiring must be performed only by an
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” in air bag system section before performing service
on or around the air bag system components or wiring. Failure to follow WARNINGS could result in
unintentional activation of the system or could render the system inoperative. Either of these two
conditions may result in severe injury.
Technical service work must be started at least 90 seconds after the ignition switch is turned to the
“LOCK” position and negative cable is disconnected from the battery. Otherwise, the system may
be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
NOTE:
All steering gear fasteners are important attaching parts in that they could affect the performance of
vital parts and systems, and/or could result in major repair expense. They must be replaced with one
of the same part number or with an equivalent part if replacement becomes necessary. Do not use a
replacement part of lesser quality or substitute design. Torque values must be used as specified dur-
ing reassembly to assure proper retention of these parts.

WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System:
Service on and around the air bag system components or wiring must be performed only by an
authorized SUZUKI dealer. Please observe all WARNINGS and “Service Precautions” under “On-
Vehicle Service” in air bag system section before performing service on or around the air bag sys-
tem components or wiring. Failure to follow WARNINGS could result in unintentional activation of
the system or could render the system inoperative. Either of these two conditions may result in
severe injury.
The procedures in this section must be followed in the order listed to temporarily disable the air
bag system and prevent false diagnostic codes from setting. Failure to follow procedures could
result in possible air bag system activation, personal injury or otherwise unneeded air bag system
repairs.
CAUTION:
When fasteners are removed, always reinstall them at the same location from which they were
removed. If a fastener needs to be replaced, use the correct part number fastener for that application.
If the correct part number fastener is not available, a fastener of equal size and strength (or stronger)
may be used. Fasteners that are not reused, and those requiring thread-locking compound, will be
called out. The correct torque value must be used when installing fasteners that require it. If the above
procedures are not followed, parts or system damage could result.

General Description
This double tube type steering column has the following three important features in addition to the steering func-
tion:
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 vehi-
cle.
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 col-
umn 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 and CAUTIONS in this section and “Service Precautions” in Section 10B.
1. Driver air bag (inflator) module 6. Steering column upper cover 11. Steering lower shaft
2. Steering wheel 7. Steering column lower cover [A] : For vehicle with air bag system

–For TYPE B
a) To install the pad, hook (1) the upper part of the pad to the
pawl of the steering wheel and push in the lower part of the
pad until it fits to the set spring securely.
For vehicle with air bag system
a) Install driver air bag (inflator) module to steering wheel.
Refer to “Driver Air Bag (Inflator) Module” in this section.
Centering contact coil (for vehicle with air bag sys-
tem)
1) Check that vehicle’s wheels (front tires) are set at straight-
ahead position.
2) Check that ignition switch is at “LOCK” position.
3) Turn contact coil counterclockwise slowly with a light force till
contact coil will not turn any further. NOTE:
After installing the steering wheel, turn the steering
wheel about 1 full rotation so that the cancel cam pin fits
into the pin hole in the steering wheel and then check the
turn signal lever for proper function.
NOTE:
Contact coil can turn about 5 turns at maximum, that is, if
it is at the center position, can turn about two and a half
turns both clockwise and counterclockwise.

tion with a lock pin (2) and seal (1). Remove this lock pin
after installing contact coil and combination switch
assembly to steering column.
CAUTION:
When installing lower cover (3) and upper cover (2), be
careful so that combination switch/contact coil and com-
bination switch lead wirer is not caught between covers.
