20. INSPECT BALL JOINTS AND DUST COVERS
(a) Inspect the ball joints for excessive looseness.wJack up the front of the vehicle and support it with
stands.
w Make sure the front wheels are in a straight±ahead
position, and depress the brake pedal.
w Jack up the lower suspension arm until there is about
half a load on the front coil spring.
w Move the front wheel up and down and check that the
ball joint has no excessive play.
Maximum lower ball joint vertical play.
0.3 mm (0.012 in.)
If the play is greater than maximum, replace the ball joint.
(b) Visually check the dust covers for damage
21. C H E C K A U TO M AT I C T RANSMISSION AND
DIFFERENTIAL OIL (FLUID)
A. Inspect automatic transmission fluid
(a) Visually check the differential for fluid and leakage.
If leakage is found, check for the cause and repair.
(b) Check the fluid level with the engine idling and shift lever at ªPº.
If the level is low, add fluid.
Transmission fluid:
See item 22 (A)
B. Inspect differential oil
(a) Visually check the transmission for oil and leakage.If leakage is found, check for the cause and repair.
(b) Remove the filler plug, and feel inside the hole with your finger. Check that the oil comes to within 5 mm (0.20 in) of the
bottom edge of the filler hole.
If the level is low, add oil until it begins to run out of the filler
hole.

22. R E P L A C E A U TO M AT I C T RANSMISSION AND
DIFFERENTIAL OIL (FLUID)
A. Replace automatic transmission fluid
(a) Remove the drain plug, and drain the fluid.
(b) Clean the drain plug.
(c) Reinstall the drain plug securely.
(d) With the engine ªOFFº, add new fluid through the dipstick
tube.
Fluid type:
ATF Type T±II or equivalent
Drain and refill capacity: 1.9 liters (2.0 US qts. 1.7 lmp. qts)
(e) Start the engine and shift the selector into all positions fromªPº through ªLº, and then shift into ªPº position.
(f) With the engine idling, check the fluid level. Add fluid up the ªCOOLº level on the dipstick.
(g) Check that the fluid level is in the ªHOTº range at the normal
operating temperature (70 ± 80
C (158 ± 176
F)) and add
as necessary.
NOTICE: Do not overfill.
B. Replace differential oil
(a) Remove the filler and drain plugs, and drain the oil.
(b) Clean the drain plug.
(c) Reinstall the drain plug securely.
(d) Add new oil until it begins to run out of the filler hole.

19. BRAKE PEDAL
(a) Check that pedal for smooth operation.
(b) Check that the pedal has the proper reservedistance and freeplay.
(c) Check the brake booster function.
20. BRAKES At a safe place, check that the brakes do not
pull to one side when applied.
21. PARKING BRAKE
(a) Check that the pedal has the proper travel.
(b) On a safe incline, check that the vehicle is held securely with only the parking brake applied.
22. A U TO M AT I C T RANSMISSION PARK
MECHANISM
(a) Check the lock release button of the selector lever for proper and smooth operation.
(b) On a safe incline, check that the vehicle is held securely with the selector lever in the ªPº
position and all brakes released.

23. WINDSHIELD WASHER FLUIDCheck that there is sufficient fluid in the tank.
24. ENGINE COOLANT LEVEL
Check that the coolant level is between the
LEVEL lines on the see±through reservoir at
normal temperature (20 5C (68 5F)).
25. RADIATOR AND HOSES
(a) Check that the front of the radiator is clean and not blocked with leaves, dirt or bugs.
(b) Check the hoses for cracks, kinks, rot or loose connections.
26. BATTERY ELECTROLYTE LEVEL
Check the indicator.
When the indicator color is blue, the condition
is satisfactory. A red color indicates that dis-
tilled water must be added, and white indicates
that charging is necessary. 27. BRAKE FLUID LEVEL
Check that the brake fluid level is near the up-
per level line on the see±through reservoir.
28. ENGINE DRIVE BELT Check drive belt for fraying, cracks, wear or oili-
ness.
29. ENGINE OIL LEVEL
Check that level on the dipstick with the engine
turned off.
30. POWER STEERING FLUID LEVEL Check the level on the dipstick.
The level should be in the ªHOTº or ªCOLDº
range depending on the fluid temperature.
31. AUTOMATIC TRANSMISSION FLUID LEVEL
(a) Park the vehicle on a level surface.
(b) With the engine idling and the parking and foot brake applied, shift the selector into all
positions from ªPº to ªLº, and then shift into ªPº.
(c) Turn and pull out the dipstick and wipe off the fluid with a clean rag.
Re±insert the dipstick fully and check that the
fluid level is in the ªHOTº range.
(d) Perform this check with the fluid at normal driving temperature (70 ± 80
C (158 ± 176
F)).
If the level is at the low side, add fluid.
NOTICE: Do not overfill.
HINT: Wait about 30 minutes before checking
the fluid level after extended driving at high
speeds in hot weather, driving in heavy traffic
or with a trailer.
32. EXHAUST SYSTEM Visually inspect for cracks, holes or loose sup-
ports.
If any change in the sound of the exhaust or
smell of the exhaust fumes is noticed, have the
cause located and corrected.
