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.

BASIC INSPECTION
1. CHECK FLUID LEVEL
(a) Using SST, create a short±circuit between terminals TC
and CG of the DLC3.
SST 09843±18040
(b) Start the engine and run at idle.

The A/C switch must be turned off.

On models with active height control suspension &
adaptive variable suspension, turn the height con-
trol switch off.
(c) Slowly move the shift lever through all positions from P to
L, and move it back to the P position.
(d) Switch to the fluid temperature detection mode.
Move the shift lever from the N to the D position, or from
D to N, within 1.5 seconds. (Repeat this operation for 6 se-
conds or more.)
OK: The A/T OIL TEMP warning light comes on for 2
seconds and then goes off.
(e) Return the shift lever to the P position and disconnect ter-
minals TC and CG.
(f) Idle the engine to raise oil temperature.
(g) Lift up the vehicle immediately after the meter indicator
light (ATF temperature warning light) comes on.

The A/T OIL TEMP warning light indicates the ATF
temperature according to the following table.

(h) Remove the overflow plug and check the fluid level.
Standard:
When ATF overflowsATF level is higher than specification
(Go to step (k))
When ATF does not overflow
ATF level is equal to or lower than
specification
(Go to step (i))
HINT:

ºOverflowº indicates the condition under which ATF
drains out from the overflow tube.

The capacity of the overflow tube is approximately 3 cc.
If the amount of drained ATF is little, only the fluid remain-
ing in the tube has drained out. This condition is not con-
sidered as ºoverflowº.
(i) Remove the refill plug.
(j) Add ATF through the refill hole until it flows out from the
overflow hole.
Fluid type: Toyota genuine ATF WS
(k) When the draining ATF has become a trickle, install the
overflow plug with a new gasket.
(l) Install the refill plug if removed.
(m) Lower the vehicle.
(n) Turn the ignition switch off to stop the engine.
2. CHECK FLUID CONDITION
If the fluid smells burnt or is black, replace it (see step 6).
3. INSPECT AND ADJUST SHIFT LEVER POSITION
(a) When shifting the shift lever from the N position to other
positions, check that the lever can be shifted smoothly
and accurately to each position and that the position indi-
cator comes on in accordance with the shift lever position.
If the indicator and shift lever position do not match, carry out
the following adjustment procedures.
(1) Remove the nut and disconnect the shift control
cable from the control shaft lever.
(2) Move the control shaft fully rearward.
(3) Return the control shaft lever 2 notches to the N
position.
(4) Set the shift lever to the N position.
(5) Connect the shift control cable and temporarily
install the control shaft lever nut.
(6) While holding the shift lever lightly toward the R
position side, tighten the control shaft lever nut.
