Fluid level
LEVEL CHECK AT NORMAL OPERATING TEMPERATURE
1) Stop vehicle and place it level.
2) Apply parking brake and place chocks against wheels.
3) With selector at P position, start engine.
4) Warm up engine till fluid temperature reaches normal oper-
ating temperature (70 – 80 °C (158 – 176 °F)). As a guide to
check fluid temperature, warm up engine till engine coolant
temperature meter indicated around 1 unit above “C” point.
5) Keep engine idling and shift selector slowly to “L” and back
to “P” position.
6) With engine idling, pull out dipstick, wipe it off with a clean
cloth and put it back into place.
7) Pull out dipstick again and check fluid level indicated on it.
Fluid level should be between FULL HOT and LOW HOT. if it
is below LOW HOT, add an equivalent of DEXRON
®-III up to
FULL HOT.
Fluid specification :
An equivalent of DEXRON
®-III
[A] : Shift the select lever with its button pushed in.
[B] : Shift the select lever without pushing its button.
NOTE:
DO NOT RACE ENGINE while checking fluid level, even
after the engine start.
DO NOT OVERFILL. Overfilling can causes foaming
and loss of fluid through breather. Then slippage and
transmission failure can result.
Bringing the level from LOW HOT to FULL HOT
requires 0.3 liters (0.64/0.53 US/lmp.pt).
If vehicle was driven under high load such as pulling a
trailer, fluid level should be checked about half an hour
after it is stopped.

LEVEL CHECK AT ROOM TEMPERATURE
The fluid level check at room temperature (20 – 30 °C (68 – 86
°F)) performed after repair or fluid change before test driving is
just preparation for level check of normal operating temperature.
The checking procedure itself is the same as that described previ-
ously. If the fluid level is between FULL COLD and LOW COLD,
proceed to test drive. And when the fluid temperature has
reached the normal operating temperature, check fluid level again
and adjust it as necessary.
Fluid change
1) Lift up vehicle.
2) With engine is cool, remove drain plug (1) from oil pan and
drain A/T fluid.
3) Install drain plug (1).

Service Precautions
Service and diagnosis
WARNING/CAUTION labels are attached on each part of air bag system components (SDM, air bag (inflator)
modules and seat belt pretensioners). Be sure to follow the instructions.
•Many of service procedures require disconnection of “AIR BAG” fuse and air bag (inflator) module(s) (driver
and passenger) from initiator circuit to avoid an accidental deployment.
•Do not apply power to the air bag system unless all components are connected or a diagnostic chart
requests it, as this will set a diagnostic trouble code (DTC).
•The “AIR BAG DIAGNOSTIC SYSTEM CHECK” must be the starting point of any air bag diagnostics. The
“AIR BAG DIAGNOSTIC SYSTEM CHECK” will verify proper “AIR BAG” warning lamp operation and will
lead you to the correct table to diagnose any air bag malfunctions. Bypassing these procedures may result in
extended diagnostic time, incorrect diagnosis, and incorrect parts replacements.
•Never use air bag component parts from another vehicle.
•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 beforehand to avoid component damage or unintended sys-
tem activation.
•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
(e.g., SDM is dropped, air bag (inflator) module is dropped from a height of 90 cm (3 ft) or more, seat belt
pretensioner (retractor assembly) is dropped from a height of 30 cm (1 ft) or more), never attempt disassem-
bly or repair but replace it with a new one.
•When using electric welding, be sure to disconnect air bag (inflator) module connectors (driver and passen-
ger) and seat belt pretensioner connectors (driver and passenger) respectively.
•When applying paint around the air bag system related parts, use care so that the harness or connector will
not be exposed to the paint mist.
•Never expose air bag system component parts directly to hot air (drying or baking the vehicle after painting)
or flames. WARNING:
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 on or around air bag system compo-
nents. Modifications can adversely affect air bag system performance and lead to injury.
Failure to follow procedures could result in possible air bag system activation, personal injury or
unneeded air bag system repairs.
WARNING:
When performing service on or around air bag system components or air bag wiring, follow the proce-
dures listed in the following pages to temporarily disable the air bag system.
Failure to follow procedures could result in possible air bag system activation, personal injury or
unneeded air bag system repairs.

10B-52 AIR BAG SYSTEM
LIVE (UNDEPLOYED) AIR BAG (INFLATOR) MODULES
Special care is necessary when handling and storing a live (unde-
ployed) air bag (inflator) modules.
The rapid gas generation produced during deployment of the air
bag could cause the air bag (inflator) module, or an object in front
of the air bag (inflator) module, to be thrown through the air in the
unlikely event of an accidental deployment.
•Never attempt disassembly of the air bag (inflator) modules.
•If any abnormality is found, be sure to replace it with new
one as an assembly.
•When an abnormality is noted as existing in the live (unde-
ployed) air bag (inflator) module, be sure to deploy it before
discarding it.
•When grease, cleaning agent, oil, water, etc., got on the air
bag (inflator) modules (driver and passenger), wipe it off
immediately with a dry cloth.
•If air bag (inflator) module was dropped from a height of 90
cm (3 ft) or more, it should be replaced with a new one as an
assembly. WARNING:
Never attempt to measure the resistance of the air bag
(inflator) modules (driver and passenger). It is very dan-
gerous as the electric current from the tester may deploy
the air bag.
WARNING:
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.
Otherwise, personal injury may result.

10B-54 AIR BAG SYSTEM
DEPLOYED AIR BAG (INFLATOR) MODULE AND ACTI-
VATED SEAT BELT PRETENSIONER
Refer to the procedure described under “DEPLOYED AIR BAG
(INFLATOR) MODULE AND ACTIVATED SEAT BELT PRETEN-
SIONER DISPOSAL” in this section for disposal. WARNING:
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 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.
WARNING:
The air bag (inflator) module and seat belt pretensioner
immediately after deployment/activation is very hot.
Wait for at least 30 minutes to cool it off before pro-
ceeding the work.
Do not apply water, oil, etc. to deployed air bag (infla-
tor) module and to activate seat belt pretensioner.
After an air bag (inflator) module has been deployed,
the surface of the air bag may contain a powdery resi-
due. This powder consists primarily of cornstarch
(used to lubricate the bag as it inflates) and by-prod-
ucts of the chemical reaction. As with many service
procedures, gloves and safety glasses should be
worn.
Wash your hands with mild soap and water after com-
pleting the work.

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.
