TIRE DIAGNOSIS
IRREGULAR AND / OR PREMATURE WEAR
Irregular and premature wear has many possible causes. Some of
them are: incorrect inflation pressures, lack of tire rotation, driving
habits, improper alignment.
If the following conditions are noted, rotation is in order:
1. Front tire wear is different from rear.
2. Uneven wear exists across the tread of any tire.
3. Left front and right front tire wear is unequal.
4. Left rear and right rear tire wear is unequal.
5. There is cupping, flat spotting, etc.
A wheel alignment check is in order if the following conditions are
noted:
1. Left front and right front tire wear is unequal.
2. Wear is uneven across the tread of any front tire.
3. Front tire treads have scuffed appearance with ªfeatherº edges
on one side of tread ribs or blocks.
WEAR INDICATOR
The original equipment tires have built-in tread wear indicators to
show when tires need replacement. These indicators will appear as
12 mm (0.47 in.) wide bands when the tire tread depth becomes 1.6
mm (0.063 in.). When the indicators appear in 3 or more grooves
at 6 locations, tire replacement is recommended.
RADIAL TIRE WADDLE
Waddle is side to side movement at the front and / or rear of the ve-
hicle. It is caused by the steel belt not being straight within the tire.
It is most noticeable at low speed, 8 to 48 km / h (5 to 30 mph). It is
possible to road test a vehicle and tell on which end of the vehicle
the faulty tire is located. If the waddle tire is on the rear, the rear end
of the vehicle will shake from side to side or ªwaddleº. From the driv-
er's seat it feels as though someone is pushing on the side of the
vehicle. If the faulty tire is on the front, the waddle is more visual.
The front sheet metal appears to be moving back and forth and the
driver feels as though he is at the pivot point in the vehicle.
Waddle can be quickly diagnosed by using a Tire Problem Detector
(TPD) and following the equipment manufacturer's recommenda-
tions.
If a TPD is not available, the more time consuming method of sub-
stituting known good tire / wheel assemblies on the problem vehicle
can be used as follows:

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 bolts 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.

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.

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.

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.
