Important
WARNING/CAUTION/NOTE
Please read this manual and follow its instructions carefully. To emphasize special information, the words
WARNING, CAUTION
and NOTE
have special meanings. Pay special attention to the messages highlighted by
these signal words.
WARNING:
Indicates a potential hazard that could result in death or injury.
CAUTION:
Indicates a potential hazard that could result in vehicle damage.
NOTE:
Indicates special information to make maintenance easier or instructions clearer.
WARNING:
This service manual is intended for authorized Suzuki dealers and qualified service mechanics only.
Inexperienced mechanics or mechanics 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 mechanic 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 (air bag (inflator) modules, forward sensor(s),
SDM and/or seat belt pretensioners) beforehand to avoid component damage or unintended activa-
tion.

Service on or around the air bag system components or wiring must be performed only by an
authorized SUZUKI dealer. Please observe all WARNINGS and “Service Precautions” under “On-
Vehicle Service” in this section before performing service on or around the air bag system compo-
nents or wiring. Failure to follow WARNINGS could result in unintended activation of the system or
could render the system inoperative. Either of these two conditions may result in severe injury.
The procedures in this section must be followed in the order listed to disable the air bag system
temporarily and prevent false diagnostic trouble codes from setting. Failure to follow procedures
could result in possible activation of the air bag system, personal injury or otherwise unneeded air
bag system repairs.
CAUTION:
When fasteners are removed, always reinstall them at the same location from which they were
removed. If a fastener needs to be replaced, use the correct part number fastener for that application.
If the correct part number fastener is not available, a fastener of equal size and strength (or stronger)
may be used. Fasteners that are not reused, and those requiring thread-locking compound, will be
called out. The correct torque value must be used when installing fasteners that require it. If the above
conditions are not followed, parts or system damage could result.
NOTE:
For the descriptions (items) not found in this section, refer to the same section of the Service Manual
mentioned in the FOREWORD of this manual.

5) Set air bag (inflator) module or seat belt pretensioner as fol-
lows.
[In case of driver air bag (inflator) module]
a) Clear a space on the ground about 185 cm (6 ft) (3) in
diameter where the driver air bag (inflator) module (1) is to
be deployed. A paved, outdoor location where there is no
activity is preferred. If an outdoor location is not available, a
space on the shop floor where there is no activity and suffi-
cient ventilation is recommended.
Ensure no loose or flammable objects are within the
deployment area.
b) Place the driver air bag (inflator) module (1), with its vinyl
trim cover facing up (2), on the ground in the space just
cleared.
[In case of passenger air bag (inflator) module]
a) Clear a space on the ground about 185 cm (6 ft) (2) in
diameter where the fixture (special tool) with attached air
bag (inflator) module (1) is to be placed for deployment. A
paved outdoor location where there is no activity is pre-
ferred. If an outdoor location is not available, a space on the
shop floor where there is no activity and sufficient ventila-
tion is recommended. Ensure that no loose or flammable
objects are within the deployment area.
b) Place special tool (passenger air bag (inflator) module
deployment fixture) on the ground in the space cleared in
step a), if it has not already been placed there.

(B) : 09932-75041 WARNING:
For handing 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 the seat belt pretensioner by the wire or
connector of the pretensioner.
When placing a live seat belt pretensioner on the work-
bench or other surface, 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 (1) or to put a seat belt pretensioner on top of
another.
Otherwise, personal injury may result.
