WARNING:
For vehicles equipped with Supplement 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 Section 10B in order to confirm whether you are performing service on or
near the air bag system components or wiring. Please observe all WARNINGS and “Service Precau-
tions” under “On-Vehicle Service” in Section 10B before performing service on or around the air
bag system components or wiring. Failure to follow WARNINGS could result in unintentional activa-
tion of the system or could render the system inoperative. Either or 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).
NOTE:
For the descriptions (items) not found in this section, refer to the same section of the Service Manual

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 CFC-12 (R-12) and the other using refrigerant HFC-134a (R-134a).
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 the descriptions (items) not found in this section, refer to the same section of the Service Man-
ual mentioned in FOREWORD of this manual.
For basic servicing method of the air conditioning system that is not described in this section, refer
to “AIR CONDITIONING BASIC MANUAL (99520-02130)”.
AIR CONDITIONING (OPTIONAL) 1B-19
Refrigerant Recovery, Evacuation and Charging
Operation Procedure for Charging A/C with Refrigerant
WARNING:
Your eyes should not be exposed to refrigerant (liquid).
Any liquid Refrigerant-134a escaping by accident shows a temperature as low as approx. –6 °C
(21.2 °F) below freezing point. Should liquid HFC-134a (R-134a) get into your eyes, it may cause a
serious injury. To protect your eyes against such accident, it is necessary to always wear goggles.
Should it occur that HFC-134a (R-134a) strikes your eye(s), consult a doctor immediately.
–Do not use your hand to rub the affected eye(s). Instead, use quantities of fresh cold water to
splash it over the affected area to gradually raise temperature of such area above freezing point.
–Obtain proper treatment as soon as possible from a doctor or eye specialist.
Should the HFC-134a (R-134a) liquid come into contact with your skin, the affected area should be
treated in the same manner as when skin is frostbitten or frozen.
Refrigerant must not be handled near where welding or steam cleaning is performed.
Refrigerant should be kept at a cold and dark place. It should never be stored where a high temper-
ature is anticipated, e.g. where exposed to direct sun light, close to fire or inside vehicle (including
trunk room).
Avoid breathing fumes produced when HFC-134a (R-134a) is burned. Such fumes may be hazardous
to health.
Start evacuating
Charge proper amount of refrigerant
in gas form
Amount of refrigerant
Dual A/C model : 750±50g (1.65±0.11 lb, 26.45±1.76 oz)
Single A/C model : 500±50g (1.1±0.11 lb, 17.64±1.76 oz)
Inspect and repair connections Stop evacuating
Performance test
Check system for pressure tightness
Charge A/C with refrigerant
Check system for refrigerant leaks and
refrigerant charging quantity
20 minutes
Wait 10 minutes
If gauge shows abnormal conditions
AIR CONDITIONING (OPTIONAL) 1B-23
The initial charging of the A/C system is performed from the high-
pressure side with the engine stopped.
And next, this method must be followed by charging from the low-
pressure side with the engine running.
1) Check to make sure that hoses are routed properly after
evacuating the system.
2) Connect Low-side hose (1) and High side hose (2) of the
manifold gauge set (3) in position. Thus open refrigerant
container valve (4) to purge the charging line.
3) Open the high-pressure side valve (6) and charge refrigerant
to system.
4) After a while, open the low-pressure side valve (5) and close
the high-pressure side valve (6).
5) Start engine and keep engine speed at 1500 rpm. Then,
operate air conditioning.
6) Charge A/C system with refrigerant in vapor state. At this
time, refrigerant container should be held upright.
7) When refrigerant container (3) is emptied, the use following
procedure to replace it with a new refrigerant container (3).
a) Close low pressure valve.
b) Replace empty container (3) with a refrigerant container
which has been charged with refrigerant. When using
refrigerant container tap valve (4), use following procedure
for replacement.
i) Retract needle (1) and remove refrigerant container tap
valve (4) by loosening its plate nut (2).
ii) Install previously-removed refrigerant container tap valve
(4) to a new refrigerant container (3). WARNING:
Make sure that high pressure-side valve is closed
securely.
NOTE:
Dual A/C model must be operated rear A/C system, too.

On-Vehicle Service
Precaution
When servicing air conditioning system, the following rules must be observed.
Piping
When connecting hoses and pipes, apply a few drops of compressor oil (refrigerant oil) to seats of coupling
nuts and O-ring. WARNING:
Should refrigerant HFC-134a (R-134a) strike your eye(s), consult a doctor immediately.
DO NOT USE YOUR HAND TO RUB AFFECTED EYE(S).
Instead, use quantities of fresh cold water to splash it over affected area to thus gradually raise its
temperature above the freezing point.
Obtain proper treatment as soon as possible from a doctor or eye specialist.
Should liquid refrigerant HFC-134a (R-134a) get on your skin, such affected part should be treated
in the same manner as when skin is frostbitten or frozen.
CAUTION:
None of refrigerant, compressor oil and component parts is interchangeable between two types of
A/C: one using CFC-12 (R-12) and the other using HFC-134a (R-134a).
(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:
Single A/C model is the same as SQ625 (H25 engine) model. Refer to the same section of the Service
Manual mentioned in FOREWORD of this manual.

Some parts in the Power Steering Gear Box cannot be disassembled or adjusted. For detailed infor-
mation, refer to the description of “POWER STEERING GEAR BOX ASSEMBLY”.
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 replacement part of lesser quality or substitute design. Torque values must be used as speci-
fied during reassembly to assure proper retention of these parts.
