Line Pressure Test
Purpose of this test is to check operating conditions of each part
by measuring fluid pressure in fluid pressure line. Line pressure
test requires following conditions.
•Automatic fluid is at normal operating temperature (70 to 80
°
C/158 – 176 °F).
•Fluid is filled to proper level (between FULL HOT and LOW
HOT on dipstick).
1) Apply parking brake securely and place checks against
wheels.
2) Attach oil pressure gauge to fluid pressure check hole (1) in
transmission case.
Special tool
(A) : 09925-37811-001
3) Depress foot brake fully, run engine at idle and stall.
4) Check fluid pressure in “D” or “R” range within the following
specification.
Line pressure :
5) If check result is OK, disconnect special tool, then tighten
transmission case plug to specified torque.
Tightening torque
Transmission case plug : 17 N·m (1.7 kg-m, 12.0 lb-ft) CAUTION:
After attaching oil pressure gauge, check that not fluid
leakage exists.
CAUTION:

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).
Tightening torque
A/T fluid drain plug (a) :
23 N·m (2.3 kg-m, 17.0 lb-ft)
4) Lower vehicle and fill proper amount of an equivalent of
DEXRON
®-III.
5) Check fluid level referring to “LEVEL CHECK NORMAL
OPERATING TEMPERATURE” of “FLUID LEVEL” in this
section.
Fluid specification :
An equivalent of DEXRON
®-III
Fluid capacity
When draining from drain plug hole:
2.5 liters (5.28/4.40 US/lmp.pt.)
When overhauling:

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
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.
Technical service work must be started at least 90 seconds after the ignition switch is turned to the
“LOCK” 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:
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.

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.
