Please read this manual and follow its instructions carefully. To emphasize special information, the words
, and NOTE have special meanings. Pay special attention to the messages high-
lighted by these signal words.
The circle with a slash in this manual means “Don’t do this” or “Don’t let this happen”.
WARNING!CAUTION!

Indicates a potential hazard that could result in vehicle damage.
CAUTION!
NOTE:
Indicates special information to make maintenance easier or instructions clearer.
This service manual is intended for authorized Suzuki dealers and qualified service technicians only.
Inexperienced technicians or technicians without the proper tools and equipment may not be able to
properly perform the services described in this manual.
Improper repair may result in injury to the technician and may render the vehicle unsafe for the driver
and passengers.
WARNING!
For vehicles equipped with a 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.
 If the air bag system and another vehicle system both need repair, Suzuki recommends that the air
bag system be repaired first, to help avoid unintended air bag system activation.
 Do not modify the steering wheel, instrument panel or any other air bag system component on or
around air bag system components or wiring. 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
process, remove the air bag system components, that is air bag (inflator) modules, SDM and/or seat
belt with pretensioner, beforehand to avoid component damage or unintended activation.

Precautions for Vehicles Equipped with a
Supplemental Restraint (Air Bag) System
S6RW0D0000001
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 Air Bag System
section. Failure to follow proper
procedures could result in possible air bag
system 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 system 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 process),
remove the air bag system components
beforehand to avoid component damage
or unintended air bag system activation.

Diagnosis
• When troubleshooting air bag system, be sure to
follow “Diagnosis” in Air Bag System section.
Bypassing these procedures may result in extended
diagnostic time, incorrect diagnosis, and incorrect
parts replacement.
• Never use electrical test equipment other than that
specified.
WARNING!
Never attempt to measure the resistance of
the air bag (inflator) modules (driver,
passenger, side and curtain) and seat belt
pretensioners (driver and passenger). It is
very dangerous as the electric current from
the tester may deploy the air bag or activate
the pretensioner.

and instrument panel harness)6. Driver air bag (inflator) module

• After servicing fuel, oil, coolant, vacuum, exhaust or
brake systems, check all lines related to the system
for leaks.
• For vehicles equipped with fuel injection systems,
never disconnect the fuel line between the fuel pump
and injector without first releasing the fuel pressure, or
fuel can be sprayed out under pressure.
• When performing a work that produces a heat
exceeding 80 °C (176 °F) in the vicinity of the
electrical parts, remove the heat sensitive electrical
part(s) beforehand.
• Use care not to expose connectors and electrical
parts to water which will be a cause of a trouble.• Always be careful not to handle electrical parts
(computer, relay, etc.) in a rough manner or drop
them.
Warning for Wheel (with tire) RemovalS6RW0D0000003
WARNING!
When removing any of these wheels installed
using wheel bolts, never remove all wheel
bolts at the same time. Leave at least 1 bolt
for each wheel as it is to prevent wheel from
dropping. When removing this remaining 1
bolt, hold wheel and tire so as not to allow
them to come off.

Intermittent and Poor Connection InspectionS6RW0D0006002
Most intermittent are caused by faulty electrical
connections or wiring, although a sticking relay or
solenoid can occasionally be at fault. When checking it
for proper connection, perform careful check of suspect
circuits for:
• Poor mating of connector halves, or terminals not fully
seated in the connector body (backed out).
• Dirt or corrosion on the terminals. The terminals must
be clean and free of any foreign material which could
impede proper terminal contact. However, cleaning
the terminal with a sand paper or the like is prohibited.
• Damaged connector body, exposing the terminals to
moisture and dirt, as well as not maintaining proper
terminal orientation with the component or mating
connector.
• Improperly formed or damaged terminals.
Check each connector terminal in problem circuits
carefully to ensure good contact tension by using the
corresponding mating terminal.
If contact tension is not enough, reform it to increase
contact tension or replace.• 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.
1. Check contact tension by inserting and removing just once.
2. Check each terminal for bend and proper alignment.

Downloaded from www.Manualslib.com manuals search engine 0A-3 General Information:
There are two kinds of colored wire used in this vehicle. One is single-colored wire and the other is dual-colored
(striped) wire.
The single-colored wire uses only one color symbol (i.e. “GRN”).
The dual-colored wire uses two color symbols (i.e. “GRN/YEL”). The first symbol represents the base color of the wire
(“GRN” in the figure) and the second symbol represents the color of the stripe (“YEL” in the figure).
Fasteners InformationS6RW0D0101004
Metric Fasteners
Most of the fasteners used for this vehicle are JIS-
defined and ISO-defined metric fasteners. When
replacing any fasteners, it is most important that
replacement fasteners be the correct diameter, thread
pitch and strength.
CAUTION!
Even when the nominal diameter (1) of thread
is the same, the thread pitch (2) or the width
across flats (3) may vary between ISO and
JIS. Refer to JIS-TO-ISO Main Fasteners
Comparison Table below for the difference.
Installing a mismatched bolt or nut will cause
damage to the thread.
Before installing, check the thread pitch for
correct matching and then tighten it by hand
temporarily. If it is tight, recheck the thread
pitch.

JIS-TO-ISO Main Fasteners Comparison TableFastener Strength Identification
Most commonly used metric fastener strength property
classes are 4T, 6.8, 7T, 8.8 and radial line with the class
identification embossed on the head of each bolt. Some
metric nuts will be marked with punch, 6 or 8 mark
strength identification on the nut face. Figure shows the
different strength markings.
When replacing metric fasteners, be careful to use bolts
and nuts of the same strength or greater than the original
fasteners (the same number marking or higher). It is
likewise important to select replacement fasteners of the
correct diameter and thread pitch. Correct replacement
bolts and nuts are available through the parts division.
Metric bolts: Identification class numbers or marks
correspond to bolt strength (increasing numbers
represent increasing strength).
