GENERAL MAINTENANCE
1. GENERAL NOTES
Maintenance items may vary from country to country. Check the owner's manual supplement in which
the maintenance schedule is shown.
Every service item in the periodic maintenance schedule must be performed.
Periodic maintenance service must be performed according to whichever interval in the periodic main-
tenance schedule occurs first, the odometer reading (miles) or the time interval (months).
Maintenance service after the last period should be performed at the same interval as before unless
otherwise noted.
Failure to do even one item can cause the engine to run poorly and increase exhaust emissions.
2. WINDSHIELD WASHER FLUID
Check that there is sufficient fluid in the tank.
3. ENGINE COOLANT LEVEL
Check that the coolant level is between the FULL and LOW lines on the see±through reservoir.
4. RADIATOR AND HOSES
(a) Check that the front of the radiator is clean and not blocked with leaves, dirt or bugs.
(2UZ±FE engine: See page CO±14)
(b) Check the hoses for cracks, kinks, rot or loose connections.
5. BATTERY ELECTROLYTE LEVEL
Check that the electrolyte level of all battery cells is between the upper and lower level lines on the case.
6. BRAKE AND CLUTCH FLUID LEVELS
Check that the brake and clutch fluid levels are near the upper level line on the see±through reservoirs.
7. ENGINE DRIVE BELTS
Check all drive belts for fraying, cracks, wear or oiliness.
8. ENGINE OIL LEVEL
Check the level on the dipstick with the engine turned off.
9. POWER STEERING FLUID LEVEL
(a) Check the level on the dipstick.
(b) The level should be in the HOT or COLD range depending on the fluid temperature.
10. AUTOMATIC TRANSMISSION FLUID LEVEL
(a) Park the vehicle on a level surface.
(b) With the engine idling and the parking brake applied, shift the selector into all positions from the P to
L, and then shift into the P position.
(c) Pull out the dipstick and wipe off the fluid with a clean rag. Re±insert the dipstick and check that the
fluid level is in the HOT range.
(d) Do this check with the fluid at normal driving temperature (70 ± 80°C, 158 ± 176°F).
HINT:
Wait until the engine cools down (approx. 30 min.) before checking the fluid level after extended driving at
high speeds, in hot weather, in heavy traffic or pulling a trailer.
11. EXHAUST SYSTEM
(a) Visually inspect for cracks, holes or loose supports.
(b) If any change in the sound of the exhaust or smell of the exhaust fumes is noticed, find the cause and
correct.

INSPECTION
1. INSPECT STEERING LINKAGE
(a) Check the steering wheel free play (See page SR±9).
(b) Check the steering linkage for looseness or damage.
Check that:
Tie rod ends do not have excessive play.
Dust seals are not damaged.
Boot clamps are not loose.
2. INSPECT SRS AIRBAG (See page RS±3)
3. INSPECT STEERING GEAR HOUSING OIL
Check the steering gear housing for oil leaks.
If leakage is found, check the cause and repair.
4. 4WD:
INSPECT DRIVE SHAFT BOOTS
Inspect the drive shaft boots for clamp looseness, grease leak-
age or damage.
5. INSPECT BALL JOINTS AND DUST COVERS
(a) Inspect the ball joints for excessive looseness.
(b) Inspect the dust cover for damage.
6. 2WD:
CHECK OIL LEVEL IN AUTOMATIC TRANSMISSION
AND DIFFERENTIAL
(a) Automatic transmission:
Check that the fluid level is in the ºHOTº range at the nor-
mal operating temperature (70 ± 80°C or 158 ± 176°F)
and add as necessary.
NOTICE:
Do not overfill.

(b) Differential:
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 hole. If the level is low, add oil
until it reaches the bottom of the filler hole.
Differential oil: See page SA±129
7. 4WD:
CHECK OIL LEVEL IN AUTOMATIC TRANSMISSION,
TRANSFER AND DIFFERENTIAL
(a) Automatic transmission:
Check that the fluid level is in the ºHOTº range at the nor-
mal operating temperature (70 ± 80°C or 158 ± 176°F)
and add as necessary.
NOTICE:
Do not overfill.
Transmission fluid (A/T): See page DI±524
(b) Transfer:
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 hole. If the level is low, add oil
until it reaches the bottom of the filler hole.
Transfer oil: See page TR±4
(c) Differential:
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 hole. If the level is low, add oil
until it reaches the bottom of the filler hole.
