3) Install steering column upper and lower cover.
4) Tighten steering column cover screws.
CAUTION:
When installing lower cover and upper cover, be careful
so that combination switch lead wire is not caught be-
tween covers.
5) Install steering column hole cover.
6) Install steering wheel to steering column. Refer to ªSTEERING
WHEELº in this section.
7) Connect battery negative cable.
STEERING COLUMN ASSEMBLY
CAUTION:
Once the steering column is removed from the vehicle, the
column is extremely susceptible to damage.
Dropping the column assembly on its end could collapse
the steering shaft or loosen the plastic shear pins which
maintain column length. Leaning on the column assembly
could cause it to bend or deform.
Any of the above damage could impair the column's col-
lapsible design.
When loosening steering column mounting bolts, make
sure that steering column assembly and steering shaft low-
er assembly have been separated. Loosening them with
steering column assembly and steering shaft lower assem-
bly assembled could cause damage to bearing in steering
shaft lower assembly.
NOTE:
When servicing steering column or any column-mounted
component, remove steering wheel. But when removing steer-
ing column simply to gain access to instrument panel compo-
nents, leave steering wheel installed on steering column.
REMOVAL
1) Disconnect negative battery cable at battery terminal.

INSPECTION
NOTE:
Vehicles involved in accidents resulting in body damage,
where steering column has been impacted or air bag
deployed, may have a damaged or misaligned steering col-
umn.
CHECKING PROCEDURE
1) Check that two capsules are attached to steering column brack-
et securely. Check clearance between capsules and steering
column bracket. Clearance should be 0 mm (0 in.) on both sides.
If found loose or clearance, replace steering column assembly.
2) Check two plates for any damages such as crack or breakage.
If anything is found faulty, replace as steering column assembly.
3) Take measurement ªaº as shown. If it is shorter than specified
length, replace column assembly with new one.

ACCIDENT DAMAGE
NOTE:
Vehicles involved in accidents resulting in body damage,
where steering column has been impacted, may have a dam-
aged or misaligned steering column.
CHECKING PROCEDURE
1) Check that two capsules are attached to steering column brack-
et securely. Check clearance between capsules and steering
column bracket. Clearance should be 0 mm (0 in.) on both sides.
If found loose or clearance, replace steering column assembly.
2) Check two plates for any damages such as crack or breakage.
If anything is found faulty, replace as steering column assembly.
3) Take measurement ªaº as shown. If it is shorter than specified
length, replace column assembly with new one.

0.8 mm (35.24
0.03 in.)
4) Check steering column lower seal for breakage or deformation.
If found defective, replace.
5) Check steering shaft joints and shaft for any damages such as
crack, breakage, malfunction or excessive play.
If anything is found faulty, replace as steering shaft lower assem-
bly or steering column assembly.
6) Check steering shaft for smooth rotation.
If found defective, replace as column assembly.
7) Check steering shaft and column for bend, cracks or deforma-
tion.
If found defective, replace as column assembly.

AIR BAG STEERING WHEEL AND COLUMN
WARNING:

Service on and around the air bag system components or wiring must be performed only by an autho-
rized SUZUKI dealer. Please observe all WARNINGS and ªService Precautionsº under ªOn-Vehicle
Serviceº in air bag system section before performing service on or around the air bag system compo-
nents 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 disable the air bag system tem-
porarily and prevent false diagnostic trouble codes from setting. Failure to follow procedures could
result in possible activation of the air bag system, personal injury or otherwise unneeded air bag sys-
tem repairs.
CAUTION:
When fasteners are removed, always reinstall them at the same location from which they were re-
moved. 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 proce-
dures are not followed, parts or system damage could result.

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.

3) Connect all connectors that have been removed in removal.
4) Install steering column upper and lower cover, and then tighten
steering column cover screws.
CAUTION:
When installing lower cover and upper cover, be careful
so that contact coil and combination switch lead wire is
not caught between covers.
5) Install steering column hole cover.
6) Install steering wheel to steering column. Refer to ªSTEERING
WHEELº in this section.
STEERING COLUMN
CAUTION:
Once the steering column is removed from the vehicle, the
column is extremely susceptible to damage.
Dropping the column assembly on its end could collapse
the steering shaft or loosen the plastic shear pins which
maintain column length leaning on the column assembly
could cause it to bend or deform.
Any of the above damage could impair the column's col-
lapsible design.
When loosening steering column mounting bolts, make
sure that steering column assembly and steering shaft low-
er assembly have been separated. Loosening them with
steering column assembly and steering shaft lower assem-
bly assembled could cause damage to bearing in steering
shaft lower assembly.
NOTE:
When servicing steering column or any column-mounted
component, remove steering wheel. But when removing steer-
ing column simply to gain access to instrument panel compo-
nents, leave steering wheel installed on steering column.
