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. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” 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
“LOCK” 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).

When carrying out periodic maintenance, or the vehicle is raised
for other service, check exhaust system as follows:
Check rubber mountings for damage, deterioration, and out
of position.
Check exhaust system for leakage, loose connections, dents
and damages.
If bolts or nuts are loose, tighten them to specification.
Check nearby body areas for damaged, missing, or misposi-
tioned parts, open seams, holes, loose connections or other
defects which could permit exhaust fumes to seep into the
vehicle.
Make sure that exhaust system components have enough
clearance from the underbody to avoid overheating and pos-
sible damage to the floor carpet.
Any defects should be fixed at once.

Spark Plugs
REPLACEMENT
Replace spark plugs with new ones referring to “Spark Plug” in
Section 6F.
Fuel System
Air Cleaner Filter
INSPECTION
1) Remove air cleaner case clamps (1).
2) Take cleaner filter out of air cleaner case.
3) Check air cleaner filter for dirt. Replace excessively dirty fil-
ter.
4) Blow off dust by compressed air from air outlet side of filter.
5) Install air cleaner filter into case.
6) Install air cleaner case cap and clamp it securely.

Are above check results satisfactory?Go to Step 4. Check ignition sys-
tem parts (Refer to
Section 6F).
4 Check Fuel Pressure (Refer to Section 6E for details).
1) Release fuel pressure from fuel feed line.
2) Install fuel pressure gauge. See Fig. 3.
