Learning Control InitializationS6RW0D5106001
1) Connect san tool to DLC (1) with ignition switch OFF.
Special tool

2) Start engine and shift select lever to “P” range.
3) Select “Misc Test” mode on scan tool.
4) Perform “AT learned initialize” on scan tool.
A/T Fluid Level CheckS6RW0D5106002
CAUTION!
Do not use any fluid other than the specified
ATF. Use of any fluid other than the specified
ATF may cause juddering or some other
faulty condition to occur.

Level Check at Normal Operating (Hot) Temperature
– Hot Check
1) Stop vehicle and place it level.
2) Apply parking brake and place chocks against
wheels.
3) With select lever at “P” position, start engine.
4) Warm up engine till fluid temperature reaches
normal operating temperature (70 – 80 °C / 158 –
176 °F). As a guide to check fluid temperature, warm
up engine to normal operating.
5) Keep engine idling and shift select lever slowly to “L”
and back to “P” position.
6) With engine idling, pull out fluid level gauge, wipe it
off with a clean cloth and put it back into place.

7) Pull out fluid level gauge (1) again and check fluid
level indicated on it. The lowest fluid level should be
between FULL HOT (2) and LOW HOT (3). If it is
below LOW HOT, add SUZUKI ATF 3317 or Mobil
ATF 3309 up to FULL HOT.
Automatic transaxle fluid
SUZUKI ATF 3317 or Mobil ATF 3309
NOTE
• Do not race engine while checking fluid
level, even after the engine start.
• Do not overfill. Overfilling can cause
foaming and loss of fluid through breather.
Then slippage and transaxle failure can
result.
• Bringing the level from LOW HOT to FULL
HOT requires 0.4 liters (0.85 / 0.70 US/Imp.
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 (Cold) Temperature – Cold
Check
Fluid level can be checked temporarily at room (cold)
temperature which correspond to 20 – 30 °C (68 – 86
°F). This level check is considered to be preparation
before performing level check under normal operating
(hot) temperature. Checking procedure itself is the same
as that described in “Level Check at Normal Operating
(Hot) Temperature – Hot Check: ”. If fluid level is
between “FULL COLD” (4) and “LOW COLD” (5),
proceed to test drive. And when fluid temperature has
reached normal operating temperature, check fluid level
again and adjust it as necessary.
CAUTION!
Fluid level check at room (cold) temperature
is recommended only for preparation of level
check under normal (hot) operating
condition.
Failure to perform fluid level check under
normal (hot) operating temperature may
result in damage to transaxle.

A/T Fluid ChangeS6RW0D5106003
CAUTION!
Do not use any fluid other than the specified
ATF. Use of any fluid other than the specified
ATF may cause juddering or some other
faulty condition to occur.

1) Lift up vehicle.
2) Remove left side engine under cover.
3) When engine is cool, remove drain plug (1) from oil
pan (2) and drain A/T fluid.
4) Install drain plug (1).

Clutch Pedal InspectionS6RW0D5306001
Cylinder Push Rod Play “a”
1) Press clutch pedal (1) gradually with finger, stop
when slight increase of resistance is felt and
measure how much pedal has moved (push rod
play) as represented by “a” as shown.
Push rod play
“a”: Max. 3 mm (0.12 in.)
2) If “a” is not within specification, replace master
cylinder (3) or pedal arm (2).
Clutch Pedal Free Travel “b”
1) Depress clutch pedal (1), stop the moment clutch
resistance is felt, and measure how much pedal has
moved (clutch pedal free travel) as represented by
“b” in the figure.
Clutch pedal free travel
“b”
: 2 – 8 mm (0.08 – 0.31 in.)
2) If “b” is not within specification, check pedal arm (2)
and master cylinder (3) and replace defective part.
Clutch Release Margin “c”
1) Pull up parking brake fully and block wheels.
2) Start engine and keep engine at idle with neutral
gear position.
3) Without clutch pedal (1) depressed, slightly push the
shift lever to reverse position until transaxle emits
gear contact noise. Do not shift the lever to reverse
position.
4) With emitting gear contact noise, be slow to depress
clutch pedal (1), and at gear contact noise died
position (release point) stop depressing.
5) Measure distance between release point (4) and full
stroke point (5) on clutch pedal (1) which is shown by
“c” in the figure.
Clutch release margin
“c”: 25 – 55 mm (0.98 – 2.17 in.)6) If “c” is not within specification, it is possible that air
is trapped in this system. If suspected so, bleed air
referring to “Air Bleeding of Clutch System”.Upon
completion of above inspection, start engine and
check clutch for proper operation.
Clutch Fluid Level InspectionS6RW0D5306002
Refer to “Brake Fluid Level Inspection in Section 4A”.
Clutch fluid specification
: Refer to the reservoir cap of the brake master
cylinder.
Air Bleeding of Clutch SystemS6RW0D5306003
CAUTION!
When operating the pedal stroke for air
bleeding of clutch system, after releasing the
clutch pedal, be sure to wait 1 second or
more before depressing it again. Otherwise,
the oil seal of operating cylinder will be
damaged, resulting in oil leakage.

Bleed air from clutch system.
Refer to “Air Bleeding of Brake System in Section 4A”.

EPS Diagnosis General DescriptionS6RW0D6301002
The P/S system in this vehicle is controlled by the P/S control module. The P/S control module has an on-board
diagnostic system which detects a malfunction in this system. When diagnosing troubles, be sure to have full
understanding of the outline of “On-Board Diagnostic System Description” and each item in “Precautions in
Diagnosing Troubles”, and then execute diagnosis according to “EPS System Check”.
On-Board Diagnostic System DescriptionS6RW0D6301003
The P/S control module performs the on-board diagnosis (self-diagnosis) on the system and operates the “EPS”
warning light (1) as follows.
• The “EPS” warning light lights when the ignition switch is turned to ON position (but the engine at stop) regardless
of the condition of the P/S control system. This is only to check if the “EPS” warning light is operated properly.
• If the areas monitored by the P/S control module is free from any trouble after the engine start (while engine is
running), the “EPS” warning light turns OFF.
• When the P/S control module detects a trouble which has occurred in the monitored areas the “EPS” warning light
comes ON while the engine is running to warn the driver of such occurrence of the trouble and at the same time it
stores the exact trouble area in memory inside of the P/S control module.
Driving Cycle
A “Driving Cycle” consists of engine startup and engine shutoff.
3 Driving Cycles Detection Logic
The malfunction detected in the first and second driving cycle is stored in P/S control module memory (in the form of
pending DTC) but the “EPS” warning light does not light at these time. It lights up at the third detection of same
malfunction also in the next driving cycle.
