WARNING:
New and used engine oil can be hazardous.
Be sure to read ªWARNINGº in General Precaution in Sec-
tion 0A and observe what in written there.
Before draining engine oil, check engine for oil leakage. If any evi-
dence of leakage is found, make sure to correct defective part be-
fore proceeding to the following work.
1) Drain engine oil by removing drain plug.
2) After draining oil, wipe drain plug clean. Reinstall drain plug, and
tighten it securely as specified below.

3-8 STEERING, SUSPENSION, WHEELS AND TIRES
RADIAL TIRE LEAD
ªLeadº is the deviation of the vehicle from a straight path on a level
road with no pressure on the steering wheel.
Lead is usually caused by:
1) Incorrect alignment.
2) Uneven brake adjustment.
3) Tire construction.
The way in which a tire is built can produce lead in a vehicle. An ex-
ample of this is placement of the belt. Off center belts on radial tires
can cause the tire to develop a side force while rolling straight down
the road. If one side of the tire is a little larger diameter than the oth-
er, the tire will tend to roll to one side. This will develop a side force
which can produce vehicle lead.
The procedure on previous page should be used to make sure that
front alignment is not mistaken for tire lead.
1) Part of the lead diagnosis procedure is different from the tire
rotation pattern currently in the owner's and service manuals. If
a medium to high mileage tire is moved to the other side of the
vehicle, be sure to check that ride roughness has not developed.
2) Rear tires will not cause lead.
VIBRATION DIAGNOSIS
Wheel unbalance causes most of the highway speed vibration
problems. If a vibration remains after dynamic balancing, it can be
caused by three things.
1) Tire runout.
2) Wheel runout.
3) Tire stiffness variation.
Measuring tire and / or wheel free runout will uncover only part of the
problem. All three causes, known as loaded radial runout, must be
checked by using a Tire Problem Detector (TPD). If a TPD is not
available, the more time consuming method of substituting known
good tire and wheel assemblies on the problem vehicle can be
used.

POWER STEERING (P/S) SYSTEM
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 autho-
rized SUZUKI dealer. Refer to ªAir Bag System Components and Wiring Location Viewº under ªGener-
al Descriptionº in air bag system section in order to confirm whether you are performing service on
or near the air bag system components or wiring. Please observe all WARNINGS and ªService Precau-
tionsº under ªOn-Vehicle Serviceº 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
ªLOCKº position and the negative cable is disconnected from the battery. Otherwise, the system may
be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
NOTE:

Some parts in the Power Steering Gear Box cannot be disassembled or adjusted. For detailed informa-
tion, refer to the description of ªPOWER STEERING GEAR BOX ASSEMBLYº.

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 replace-
ment part of lesser quality or substitute design. Torque values must be used as specified during reas-
sembly to assure proper retention of these parts.

Although the figures in this section show only the left-hand steering vehicle, the same work procedure
and data apply to the right-hand steering vehicle.

GENERAL DESCRIPTION
TIRES
This vehicle is equipped with following tire. P215 / 65 R16, 215 / 65 R16 or 235 / 60 R16
The tires are of tubeless type. The tires are designed to operate satisfactorily with loads up to the full rated load
capacity when inflated to the recommended inflation pressure.
Correct tire pressures and driving habits have an important influence on tire life. Heavy cornering, excessively rapid
acceleration, and unnecessary sharp braking increase tire wear.
WHEELS
Standard equipment wheels are following steel wheel. 16
6 1 / 2 J or 16
7JJ
REPLACEMENT TIRES
When replacement is necessary, the original equipment type tire should be used. Refer to the Tire Placard. Re-
placement tires should be of the same size, load range and construction as those originally on the vehicle. Use
of any other size or type tire may affect ride, handling, speedometer / odometer calibration, vehicle ground clear-
ance and tire or snow chain clearance to the body and chassis.
NOTE:
Do not mix different types of tires on the same vehicle such as radial, bias and bias-belted tires except in
emergencies, because vehicle handling may be seriously affected and may result in loss of control.
It is recommended that new tires be installed in pairs on the same axle. If necessary to replace only one tire, it
should be paired with the tire having the most tread, to equalize braking traction.
