WITH A SUPPLEMENTAL RESTRAINT
(AIR BAG) SYSTEM
DIAGNOSIS
 When troubleshooting air bag system, be sure to follow
“DIAGNOSIS” 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:
 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 fol-
low proper procedures could result in possible air bag
system activation, personal injury, damage to parts or
air bag system being unable to activate when neces-
sary.
 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.

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.

GENERAL INFORMATION 0A-5
 Even when the accident was light enough not to cause air bags to activate, be sure to inspect sys-
tem parts and other related parts according to instructions under “REPAIR AND INSPECTION
REQUIRED AFTER AN ACCIDENT” in SECTION 10B.
 When servicing parts other than air bag system, if shocks may be applied to air bag system compo-
nent parts, remove those parts beforehand.
 When handling the air bag (inflator) modules (driver and passenger), seat belt pretensioners (driver
and passenger) or SDM, be careful not to drop it or apply an impact to it. If an excessive impact was
applied, never attempt disassembly or repair but replace it with a new one.
 When grease, cleaning agent, oil, water, etc. has got onto air bag (inflator) modules (driver and pas-
senger) or seat belt pretensioners (drive and passenger), wipe off immediately with a dry cloth. WARNING:
SDM
 For handling and storage of a SDM, select a place where the ambient temperature below 65°C
(150°F), without high humidity and away from electric noise.
 During service procedures, be very careful when handling a Sensing and Diagnostic Module (SDM).
Never strike or jar the SDM.
 Never power up the air bag system when the SDM is not rigidly attached to the vehicle. All SDM and
mounting bracket fasteners must be carefully torqued and the arrow must be pointing toward the
front of the vehicle to ensure proper operation of the air bag system.
The SDM could be activated when powered while not rigidly attached to the vehicle which could
cause deployment and result in personal injury.
WARNING:
Driver and Passenger Seat Belt Pretensioners
(If equipped)
 For handling and storage of a live seat belt preten-
sioner, select a place where the ambient temperature
below 65°C (150°F), without high humidity and away
from electric noise.
 Never carry seat belt pretensioner by wire or connec-
tor of pretensioner. When placing a live seat belt pre-
tensioner on the workbench or some place like that, be
sure not to lay it with its exhaust hole (1) provided side
facing down. It is also prohibited to put something on
its face with an exhaust hole or to put a seat belt pre-
tensioner on top of another. Otherwise, personal injury
may result.
 Never dispose of live (inactivated) seat belt pretension-
ers (drive and passenger). If disposal is necessary, be
sure to activate them according to activation proce-
dures described in SECTION 10B before disposal.
 The seat belt pretensioner immediately after activation
is very hot. Wait for at least half an hour to cool it off
before proceeding the work.
 With many service procedures, gloves and safety
glasses should be worn to prevent any possible irrita-
tion of the skin or eyes.

 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)”.

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 (32°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 eyes, 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 hazard-
ous to health.

ON-VEHICLE SERVICE
SERVICE PRECAUTION
When servicing air conditioning system, note the following instructions.
REFRIGERANT LINE
Never use heat for bending pipes. When bending a pipe, try to make its bending radius as slight as possible.
Keep internal parts of air conditioning free from moisture and dirt. When disconnecting any line from system,
install a blind plug or cap to the fitting immediately.
When connecting hoses and pipes, apply a few drops of compressor oil (refrigerant oil) to seats of coupling
nuts and O-ring.
When tightening or loosening a fitting, use two wrenches, one for turning and the other for support.
Tighten flared nuts by the following specified torque.
Tightening torque
8 mm pipe : 13 N·m (1.3 kg-m, 9.5 lb-ft)
12 mm pipe : 23 N·m (2.3 kg-m, 16.6 lb-ft)
14.5 mm pipe : 33 N·m (3.3 kg-m, 23.8 lb-ft) 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.
