Manual Transmission Oil
INSPECTION
1) Inspect transmission case for evidence of oil leakage.
Repair leaky point if any.
2) Make sure that vehicle is placed level for oil level check.
3) Remove level plug (2) of transmission.
4) Check oil level.
Oil level can be checked roughly by means of level plug hole.
That is, if oil flows out of level plug hole or if oil level is found
up to hole when level plug is removed, oil is properly filled.
If oil is found insufficient, pour specified amount of specified
oil.
5) Tighten level plug to specified torque.
Refer to “Maintenance Service” in Section 7A for installation
and tightening torque.
CHANGE
Change transmission oil with new specified oil referring to “Main-
tenance Service” in Section 7A.
Automatic Transmission Fluid
INSPECTION
1) Inspect transmission case for evidence of fluid leakage.
Repair leaky point, if any.
2) Make sure that vehicle is placed level for fluid level check.
3) Check fluid level.
For fluid level checking procedure, refer to “Fluid Level
Check” in Section 7B and be sure to perform it under speci-
fied conditions. If fluid level is low, replenish specified fluid.
CHANGE
1) Inspect transmission case for evidence of fluid leakage.

necessary. Repair or replace defective parts, if any.
Refer to table of “Tightening Torque Specifications” in Sec-
tion 3B (or 3B1) and 3C for particular check points.
5) Inspect steering gear box (2) for evidence of oil leakage. If
leakage is found, check oil level in gear box.
6) Check boots of steering linkage for damage (leaks, detach-
ment, tear, dent, etc.). If damage is found, replace defective
boot with new one.
7) Check wheel alignment. Refer to “Preliminary Checks Prior
to Adjusting Front Alignment” in Section 3A.
Steering Knuckle Seal
INSPECTION
1) Remove knuckle seal cover (1).
2) Check knuckle seal (2) for wear, damage and deterioration.
If defective, replace.

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).
CAUTION:
The air conditioning system of this vehicle uses refrigerant HFC-134a (R-134a).
None of refrigerant, compressor oil and component parts is interchangeable between two types of
A/C: one using refrigerant HFC-134a (R-134a) and the other using refrigerant CFC-12 (R-12).
Be sure to check which refrigerant is used before any service work including inspection and mainte-
nance. For identification between these two types, refer to “Refrigerant Type” in this section.
When replenishing or changing refrigerant and compressor oil and when replacing parts, make sure
that the material or the part to be used is appropriate to the A/C installed in the vehicle being serviced.
Use of incorrect one will result in leakage of refrigerant, damage in parts or other faulty condition.
NOTE:
For basic servicing method of the air conditioning system that is not described in this section, refer to
AIR CONDITIONING BASIC MANUAL (Part number: 99520-02130).

Abnormal Noise Diagnosis
There are various types of noise, ranging from those produced in the engine compartment to those from the
passenger compartment, also from rumbling noises to whistling noises.
Abnormal noise from compressor
Abnormal noise from magnetic clutch
Abnormal noise from tubing
Abnormal noise from condenser
Condition Possible Cause Correction
During compressor
operation, a rumbling
noise is heard propor-
tional to engine revo-
lutions.Inadequate clearance in piston area (piston or
swash-plate).Repair or replace compressor as
necessary
A loud noise is heard
at a certain rpm, dis-
proportionately to
engine revolution.Loose or faulty compressor drive belt. Adjust drive belt tension, or replace
belt.
Loose compressor mounting bolts. Retighten mounting bolts.
A loud rattle is heard
at low engine rpm.Loose compressor clutch plate bolt. Retighten clutch plate bolt.
Replace compressor if it was oper-
ated in this condition for a long
time.
Condition Possible Cause Correction
A rumbling noise is
heard when compres-
sor is not operating.Worn or damaged bearings. Replace magnet clutch assembly.
A chattering noise is
heard when compres-
sor is engaged.Faulty clutch clearance (excessive). Adjust clutch clearance.
Worn clutch friction surface. Replace magnet clutch assembly.
Compressor oil leaked from lip type seal. Replace lip type seal.
Contaminating the friction surface. Replace compressor body assem-
bly.
Condition Possible Cause Correction
A droning noise is
heard inside vehicle,
but not particularly
noticeable in engine
compartment.Faulty tubing clamps. Reposition clamps or increase the
number of clamps.
Resonance caused by pulsation from variations
in refrigerant pressure.Attach a silencer to tubing, or mod-
ify its position and length.
Condition Possible Cause Correction
Considerable vibra-
tion in condenser.Resonance from condenser bracket and body. Firmly insert a silencer between
condenser bracket and body.
