A/T FLUID
Checking A/T Fluid INFOID:0000000004305295
1. Warm up engine.
2. Check for A/T fluid leakage.
3. Before driving, A/T fluid level can be checked at A/T fluid tem- peratures of 30 ° to 50 °C (86 ° to 122 °F) using the “COLD” range
on A/T fluid level gauge.
• A : Front side
• B : Reverse side
• C : Add
• D : OK
a. Park vehicle on level surface and set parking brake.
b. Start engine and move selector lever through each gear posi- tion. Leave selector lever in “P” position.
c. Check A/T fluid level with engine idling.
d. Remove A/T fluid level gauge and wipe clean with lint-free cloth. CAUTION:
When wiping the A/T fluid l evel gauge, always use lint-free
cloth.
e. Re-insert A/T fluid level gauge into A/T fluid charging pipe as far as it will go.
CAUTION:
Firmly fix the A/T fluid level ga uge to the A/T fluid charging
pipe using the stopper attached.
f. Remove A/T fluid level gauge and note reading. If reading is at low side of range, add A/T fluid to the A/T fluid charging pipe.
CAUTION:
Do not overfill.
4. Drive vehicle for approximately 5 minutes.
5. Re-check A/T fluid level at A/T fluid temperatures of 50° to 80 °C (122 ° to 176 °F) using “HOT” range on A/
T fluid level gauge.
CAUTION:
• When wiping the A/T fluid level gauge, always use lint-free cloth.
• Firmly fix the A/T fluid level ga uge to the A/T fluid charging pipe using the stopper attached.
6. Check A/T fluid condition and make any necessary repairs. Refer to AT-51, " Inspections Before Trouble
Diagnosis " . If the A/T fluid contains frictional material (clu
tches, bands, etc.), or if the A/T is repaired, over-
hauled, or replaced, inspect and clean the A/T fluid cooler mounted in the radiator. Refer to AT-18, " A/T
Fluid Cooler Cleaning " .
7. Install the removed A/T fluid level gauge into the A/T fluid charging pipe. CAUTION:
Firmly fix the A/T fluid level gaug e to the A/T fluid charging pipe using the stopper attached.
Changing A/T Fluid INFOID:0000000004305296
1. Warm up A/T fluid.
2. Stop engine.
3. Drain A/T fluid by removing the drain plug. Re install the drain plug to the specified torque.
CAUTION:
Do not reuse drain plug gasket.
4. Refill the transaxle with new specified A/T fluid th rough the A/T fluid charging pipe. Always refill the tran-
saxle with the same volume of A/T fluid that was drained out. B

Fluid Leakage and Fluid Level Check Check fluid leakage and check the fluid level. Refer to AT-17, " Checking A/T Fluid " .
Fluid Condition Check Check the A/T fluid condition.
STALL TEST
Stall Test Procedure 1. Check ATF and engine oil levels. If necessary, add ATF and engine oil.
2. Drive vehicle for approximately 10 minutes or until ATF and engine oil reach operating temperature.
3. Set parking brake and block wheels.
4. Install a tachometer where it can be seen by driver during test. •It is good practice to mark the point of specified engine
rpm on indicator.
5. Start engine, apply foot brake, and place selector lever in “D” position.Fluid status Conceivable Cause Required Operation

TROUBLE DIAGNOSIS
Location of line pressure test ports are shown in the figure.
• Always replace pressure plugs as they are self-sealing bolts.
Line Pressure Test Procedure
1. Check ATF and engine oil levels. If necessary, add ATF or engine oil.
2. Drive vehicle for approx. 10 minutes or until engine oil and ATF reach operating temperature.
3. Install oil pressure gauge to corresponding line pressure test port.
4. Set parking brake and block wheels.
5. Start engine and measure line pressure at idle and stall speed. CAUTION:
• Keep the brake pedal pressed all the way down during
measurement.
• When measuring the line pressure at the stall speed, refer to "STALL TEST". SCIA7187E

BRAKE FLUID
On Board Inspection INFOID:0000000004305892
CHECKING BRAKE FLUID LEVEL • Make sure the fluid level in the reservoir tank is within the standard (between MAX and MIN lines).
• Visually check around the reservoir tank for fluid leaks.
• If fluid level is excessively low, check brake system for fluid leaks.
• Release parking brake lever and see if brake warning lamp goes
off. If not, check brake system for fluid leaks.
Drain and Refill INFOID:0000000004305893
CAUTION:
• Refill using recommended brake fluid. Refer to MA-14, " Fluids and Lubricants " .
• Never reuse drained brake fluid.
• Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted areas, immediately wipe th em with cloth and wash it away with water.
• Before working, disconnect connect ors of ABS actuator and electric unit (control unit) or battery
negative terminal.
1. Connect a vinyl tube to bleed valve.
2. Depress the brake pedal, loosen the bleed valve, and gradually remove the brake fluid.
3. Clean inside of reservoir tank, and refill with new brake fluid.
4. Loosen bleed valve, depress brake pedal slowly to full stroke and then release it. Repeat the procedure every 2 or 3 seconds
until the new brake fluid comes out, then close the bleed valve
while depressing the brake pedal . Repeat the same procedure
for each wheel.
5. Bleed the air from the brake hydraulic system. Refer to BR-9," Bleeding Brake System " .
Bleeding Brake System INFOID:0000000004305894
CAUTION:
• While bleeding, pay attention to master cylinder fluid level.
• Before working, disconnect connectors of ABS actuator and electri c unit (control unit) or the battery
cable from the negative terminal.
1. Connect a vinyl tube to the rear right bleed valve.
2. Fully depress brake pedal 4 to 5 times.
