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.

S5JB0A0000001
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 “Precautions on
Service and Diagnosis of Air Bag System
in Section 8B”. 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.

Precautions: 00-2
Diagnosis
• When troubleshooting air bag system, be sure to
follow “Air Bag Diagnostic System Check in Section
8B”. 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 pretensioners.
Servicing and Handling
WARNING !
Many of service procedures require
disconnection of “A/B” fuse and all air bag
(inflator) module(s) from system circuit to
avoid an accidental deployment.
Driver, Passenger, Side and Curtain Air Bag
(Inflator) Modules
• For handling and storage of a live air bag
(inflator) module, select a place where the
ambient temperature below 65 °C (150 °F),
without high humidity and away from
electric noise.
• When carrying a live air bag (inflator)
module, make sure the bag opening is
pointed away from you. In case of an
accidental deployment, the bag will then
deploy with minimal chance of injury.
Never carry the air bag (inflator) module by
the wires or connector on the underside of
the module. When placing a live air bag
(inflator) module on a bench or other
surface, always face the bag up, away from
the surface. This is necessary so that a
free space is provided to allow the air bag
to expand in the unlikely event of
accidental deployment. Otherwise,
personal injury may result.
I5JB0A000001-02
[A]: Always carry air bag (inflator) module with trim cover (air bag opening)
away from body.
[B]: Always place air bag (inflator) module on workbench with trim cover (air
bag opening) up, away from loose objects.
[A]
[B]
I5JB0A000002-02
00-3 Precautions:
• Never dispose of live (undeployed) air bag
(inflator) modules (driver, passenger, side
and curtain). If disposal is necessary, be
sure to deploy them according to
deployment procedures described in “Air
Bag (Inflator) Module and Seat Belt
Pretensioner Disposal in Section 8B”.
• The air bag (inflator) module immediately
after deployment is very hot. Wait for at
least half an hour to cool it off before
proceeding the work.
• After an air bag (inflator) module has been
deployed, the surface of the air bag may
contain a powdery residue. This powder
consists primarily of cornstarch (used to
lubricate the bag as it inflates) and by-
products of the chemical reaction. As with
many service procedures, gloves and
safety glasses should be worn.
WARNING !
SDM
• 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
• For handling and storage of a live seat belt
pretensioner, 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 connector of pretensioner. When
placing a live seat belt pretensioner 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
pretensioner on top of another. Otherwise,
personal injury may result.
• Never dispose of live (inactivated) seat belt
pretensioners (drive and passenger). If
disposal is necessary, be sure to activate
them according to activation procedures
described in “Air Bag (Inflator) Module and
Seat Belt Pretensioner Disposal in Section
8B” 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 irritation of the skin or eyes.
