PRECAUTIONS
PRECAUTION FOR VEHICLES EQUIPPED
WITH A SUPPLEMENTAL RESTRAINT
(AIR BAG) SYSTEM
WARNING:
The configuration of air bag system parts are as shown in
the figure. When it is necessary to service (remove, rein-
stall and inspect) these parts, be sure to follow proce-
dures described in SECTION 10B. Failure to follow proper
procedures could result in possible air bag system activa-
tion, personal injury, damage to parts or air bag system
being unable to activate when necessary.
If the air bag system and another vehicle system both
need repair, SUZUKI recommends that the air bag system
be repaired first, to help avoid unintended air bag system
activation.
Do not modify the steering wheel, dashboard, or any other
air bag system components. Modifications can adversely
affect air bag system performance and lead to injury.
If the vehicle will be exposed to temperatures over 93C
(200F) (for example, during a paint baking process), re-
move the air bag system components beforehand to avoid
component damage or unintended air bag system activa-
tion.
DIAGNOSIS
When troubleshooting air bag system, be sure to follow
ªDIAGNOSISº in SECTION 10B. Bypassing these proce-
dures may result in extended diagnostic time, incorrect diag-
nosis, and incorrect parts replacement.
Never use electrical test equipment other than that specified
in this manual.
WARNING:
Never attempt to measure the resistance of the air bag (in-
flator) modules (driver and passenger) and seat belt preten-
tioners (driver and passenger). It is very dangerous as the
electric current from the tester may deploy the air bag or ac-
tivate the pretensioner.

Steering System Inspection
1) Check steering wheel for play and rattle, holding vehicle in
straight forward condition on the ground.
Steering wheel play ªaº: 0 ± 30 mm (0 ± 1.2 in.)
2) Check universal joints of steering shaft for rattle and damage. If
rattle or damage is found, replace defective part with a new one.
3) Check steering linkage for looseness and damage. Repair or re-
place defective part, if any.
4) Check bolts and nuts for tightness and retighten them as neces-
sary. Repair or replace defective parts, if any.
Refer to table of Tightening Torque Specification in Section 3B
(or 3B1) and 3C (or 3C1) for particular check points.
5) Check boots of steering linkage for damage (leaks, detachment,
tear, dent, etc.). If damage is found, replace it with new one.
If any dent is found on steering rack boots, correct it to original
shape by turning steering wheel to the right or left as far as it
stops and holding it for a few seconds.
6) Check wheel alignment.
NOTE:
For details of wheel alignment, refer to Wheel Alignment in
Section 3A.
ITEM 6-15
Power Steering (P / S) System Inspection (if equipped)
1) Visually check power steering system for fluid leakage and hose
for damage and deterioration.
Repair or replace defective parts, if any.
2) With engine stopped, check fluid level indicated on fluid tank,
which should be between MAX and MIN marks. If it is lower than
MIN, fill fluid up to MAX mark.
NOTE:
Be sure to use an equivalent of DEXRON
-II or DEX-
RON
-III for P / S fluid.
Fluid level should be checked when fluid is cool.
