Precautions
Precaution for Vehicles Equipped with a Sup-
plemental Restraint (Air Bag) System
Diagnosis
 When troubleshooting air bag system, be sure to follow “Air
Bag Diagnostic System Check” in Section 10B. Bypassing
these procedures may result in extended diagnostic time,
incorrect diagnosis, and incorrect parts replacement.
 Never use electrical test equipment other than that specified
in this manual. WARNING:
 The configuration of air bag system parts are as shown
in the figure. When it is necessary to service (remove,
reinstall and inspect) these parts, be sure to follow
procedures described in Section 10B. Failure to follow
proper procedures could result in possible air bag sys-
tem activation, 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 sys-
tem 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
93°C (200°F) (for example, during a paint baking pro-
cess), remove the air bag system components before-
hand to avoid component damage or unintended air
bag system activation.
1. Air bag wire harness (in instrument panel
wire harness and floor wire harness)5. Contact coil
2. Passenger air bag (inflator) module 6. Driver air bag (inflator) module
3. SDM 7. Seat belt pretensioner (if equipped)
4. DLC
WARNING:
Never attempt to measure the resistance of the air bag
(inflator) modules (driver and passenger) and seat belt
pretensioners (driver and passenger). It is very danger-
ous as the electric current from the tester may deploy the
air bag or activate the pretensioner.

6) Replenish oil until oil level is brought to FULL level mark on
dipstick. (oil pan and oil filter capacity). The filler inlet is at
the top of the cylinder head cover.
It is recommended to use engine oil of SE, SF, SG, SH, SJ or
SL grade.
Select the appropriate oil viscosity according to the proper
engine oil viscosity chart [A].
Engine oil specification
7) Check oil filter and drain plug for oil leakage.
8) Start engine and run it for three minutes. Stop it and wait five
minutes before checking oil level. Add oil, as necessary, to
bring oil level to FULL level mark on dipstick.
Engine Coolant
CHANGE
Change engine coolant referring to “Cooling System Flush and
Refill” in Section 6B.
Exhaust System
INSPECTION
Oil pan capacity About 3.8 liters (8.0/6.7 US/lmp pt.)
Oil filter capacity About 0.2 liters (0.4/0.3 US/lmp pt.)
Others About 0.3 liters (0.6/0.5 US/lmp pt.)
Total About 4.3 liters (9.1/7.6 US/lmp pt.)
NOTE:
Engine oil capacity is specified. However, note that the
amount of oil required when actually changing oil may
somewhat differ from the data in the table depending on
various conditions (temperature, viscosity, etc.)
1. Full level mark (hole)
2. Low level mark (hole)
WARNING:
To avoid danger of being burned, do not touch exhaust
system when it is still hot. Any service on exhaust sys-
tem should be performed when it is cool.

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).

Refrigerant Recovery, Evacuating and Charging
Operation Procedure for Refrigerant Charging
WARNING:
 Your eyes should not be exposed to refrigerant (liquid).
Any liquid HFC-134a (R-134a) escaping by accident shows a temperature as low as approximately
–6 °C (21 °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 gog-
gles. Should it occur that HFC-134a (R-134a) strikes your eyes(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.

Handling refrigerant HFC-134a (R-134a)
Always wear goggles to protect your eyes.
Avoid you direct contact to liquid refrigerant.
Do not heat refrigerant container higher than 40 °C (104 °F).
Do not discharge refrigerant into atmosphere.
Do not allow liquid refrigerant to touch bright metals. Refrigerant combined with moisture is corrosive and
will tarnish surfaces of bright metals including chrome. 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:
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-
