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.

3C-2 STEERING WHEEL AND COLUMN
GENERAL DESCRIPTION
STEERING COLUMN
This double tube type steering column has 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 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.
STEERING WHEEL AND DRIVER AIR BAG (INFLATOR) MODULE
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 and “SERVICE PRECAUTIONS” under “ON-VEHICLE SER-
VICE” in Section 10B.
DIAGNOSIS
For maintenance service of the steering wheel and column, refer to Section 0B.
For diagnosis of the steering wheel and column, refer to Section 3.
For diagnosis of the air bag system, refer to Section 10B.
INSPECTION AND REPAIR REQUIRED AFTER ACCIDENT
After an accident, whether the air bag has been deployed or not, be sure to perform checks, inspections and
repairs described under “CHECKING STEERING COLUMN ASSEMBLY AND LOWER SHAFT FOR ACCI-
DENT DAMAGE” as well as “REPAIRS AND INSPECTIONS REQUIRED AFTER ACCIDENT” under “DIAGNO-
SIS” in Section 10B.
