0A-6 GENERAL INFORMATION
CAUTION:
Even when the accident was light enough not to cause air
bags to activate, be sure to inspect system parts and other
related parts according to instructions under ªRepair and
Inspection Required after an Accidentº in SECTION 10B.
When servicing parts other than air bag system, if shocks
may be applied to air bag system component parts, re-
move those parts beforehand.
When handling the air bag (inflator) modules (driver and
passenger), seat belt pretensioners (driver and passen-
ger) or SDM, be careful not to drop it or apply an impact to
it. If an excessive impact was applied (e.g., dropped from
a height of 91.4 cm (3 feet) or more), never attempt disas-
sembly 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 passenger) or seat
belt pretensioners (drive and passenger), wipe off im-
mediately with a dry cloth.
Air bag wire harness can be identified easily as it is cov-
ered with a yellow protection tube. Be very careful when
handling it.
When an open in air bag wire harness, damaged wire har-
ness, connector or terminal is found, replace wire har-
ness, connectors and terminals as an assembly.
Do not apply power to the air bag system unless all com-
ponents are connected or a diagnostic chart requests it,
as this will set a diagnostic trouble code.
Never use air bag system component parts from another
vehicle.
When using electric welding, be sure to temporarily dis-
able air bag system referring to ªDisabling Air Bag Sys-
temº described in ªService Precautionsº under ªOn-Ve-
hicle Serviceº in SECTION 10B.
Never expose air bag system component parts directly to
hot air (drying or baking the vehicle after painting) or
flames.
WARNING / CAUTION labels are attached on each part of
air bag system components. Be sure to follow the instruc-
tions.
After vehicle is completely repaired, perform ªAir Bag
Diagnostic System Checkº described in ªDiagnosisº in
SECTION 10B.

0A-16 GENERAL INFORMATION
Poor terminal-to-wire connection.
Check each wire harness in problem circuits for poor connection
by shaking it by hand lightly. If any abnormal condition is found,
repair or replace.
Wire insulation which is rubbed through, causing an intermittent
short as the bare area touches other wiring or parts of the vehicle.
Wiring broken inside the insulation. This condition could cause
continuity check to show a good circuit, but if only 1 or 2 strands
of a multi-strand-type wire are intact, resistance could be far too
high.
If any abnormality is found, repair or replace.
PRECAUTION FOR INSTALLING MOBILE
COMMUNICATION EQUIPMENT
When installing mobile communication equipment such as CB (Citi-
zens-Band)-radio or cellular-telephone, be sure to observe the fol-
lowing precautions.
Failure to follow cautions may adversely affect electronic control
system.
Keep the antenna as far away as possible from the vehicle's elec-
tronic control unit.
Keep the antenna feeder more than 20 cm (7.9 in.) away from
electronic control unit and its wire harnesses.
Do not run the antenna feeder parallel with other wire harnesses.
Confirm that the antenna and feeder are correctly adjusted.

ON-VEHICLE SERVICE
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 page 1B-2).
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.
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.
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 tightening or loosening a fitting, use two wrenches, one for turning and the other for support.

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 autho-
rized SUZUKI dealer. Refer to ªAir Bag System Components and Wiring Location Viewº under ªGener-
al Descriptionº in air bag system section in order to confirm whether you are performing service on
or near the air bag system components or wiring. Please observe all WARNINGS and ªService Precau-
tionsº under ªOn-Vehicle Serviceº 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
ªLOCKº 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:
When inspecting and servicing vehicle equipped with ABS, be sure to refer to section 5E or 5E1 first.
All brake 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 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 specified during reassembly to as-
sure proper retention of all parts. There is to be no welding as it may result in extensive damage and
weakening of the metal.
