Explanation of Maintenance Items
36
The following descriptions are provided to give you a better understanding of
the maintenance items that should be performed on your vehicle. The scheduled
maintenance log indicates at which mileage/time intervals each item should be
performed. Please note that many maintenance items should be performed only
by a qualified technician.
For further information on maintenance items you can perform yourself,
see the “Vehicle Maintenance and Care” and “DoItYourself Maintenance”
sections of your
Owner’s Manual.
Automatic Transmission Fluid or Manual Transmission Oil
Inspect or replace at specified intervals. When performing inspections, check each
component for signs of leakage. If you discover any leakage, have it repaired by a
qualified technician immediately.
Ball Joints and Dust Covers
Check the suspension and steering linkage ball joints for looseness and damage.
Check all dust covers for deterioration and damage. Replace any deteriorated ordamaged parts. Aqualified technician should perform these operations.
Brake Lines and Hoses
Visually inspect for proper installation. Check for chafing, cracks, deterioration
and signs of leakage. Replace any deteriorated or damaged parts. A qualified
technician should perform these operations.
Brake Linings/Drums and Brake Pads/Discs
Check the brake linings (shoes) and drums for scoring, burning, fluid leakage,
broken parts and excessive wear. Check the pads for excessive wear and the
discs for runout, excessive wear and fluid leakage. Replace any deteriorated ordamaged parts. A qualified technician should perform these operations.
Cabin Air Filter
Replace at specified intervals. Driving in heavy traffic, on dirt roads or in urban,
desert or dusty areas may shorten filter’s life. More frequent replacement may
be necessary.
Charcoal Canister (CA, MA and NY vehicles)
Check for internal damage and clogging. If necessary, clean with compressed air
or replace. A qualified technician should perform these operations.

Be extremely cautious when work-
ing on the battery. It contains poi-
sonous and corrosive sulfuric acid.
NOTICE

Remember that battery and ignition
cable carry high currents or volt-
ages. Be careful of accidentally
causing a short circuit.

Add only Toyota Super Long Life
Coolantº or similar high quality eth-
ylene glycol based non- silicate,
non- amine, non- nitrite, and non- bo-
rate coolant with long- life hybrid
organic acid technology to fill the
radiator. Toyota Super Long Life
Coolantº is a mixture of 50% cool-
ant and 50% deionized water (for
the U.S.A.) or 55% coolant and 45%
deionized water (for Canada).

If you spill some of the coolant, be
sure to wash it off with water to
prevent it from damaging the parts
or paint.

Do not allow dirt or anything else
to fall through the spark plug holes.

Use only spark plugs of the speci-
fied type. Using other types will
cause engine damage, loss of per-
formance or radio noise.

Do not reuse iridium- tipped spark
plugs by cleaning or regapping.

Do not overfill automatic transmis-
sion fluid and power steering fluid,
or the transmission and power
steering could be damaged.

Do not drive with the air cleaner
filter removed, or excessive engine
wear could result. Also backfiring
could cause a fire in the engine
compartment.

Be careful not to scratch the glass
surface with the wiper frame.

When closing the engine hood,
check to see that you have not for-
gotten any tools, rags, etc.

Close
Check the fluid level through the reser-
voir. If necessary, add automatic trans-
mission fluid DEXRONII or III.
If the vehicle has been driven around 80
km/h (50 mph) for 20 minutes (a little
more in frigid temperatures), the fluid is
hot (80C or 175F). You may also check
the level when the fluid is cold (about
room temperature, 10CÐ30C or
50FÐ85F) if the engine has not been
run for about five hours.Clean all dirt from the outside of the res-
ervoir tank and look at the fluid level. If
the fluid is cold, the level should be in the
COLDº range. Similarly, if it is hot, the
fluid level should be in the HOTº range.
If the level is at the low side of either
range, add automatic transmission fluid
DEXRONII or III to bring the level within
the range.
To remove the reservoir cap, turn it coun-
terclockwise and lift up. To reinstall it,
turn it clockwise. After replacing the reser-
voir cap, visually check the steering box
case, vane pump and hose connections
for leaks or damage.
CAUTION
The reservoir tank may be hot so be
careful not to burn yourself.
NOTICE
Avoid overfilling, or the power steer-
ing could be damaged.

HYDRAULIC TEST
1. PERFORM HYDRAULIC TEST
(a) Measure the line pressure.
NOTICE:

Perform the test at the normal operating ATF (Automatic Transmission Fluid) temperature 50
to 80°C (122 to 176°F).

The line pressure test should always be carried out in pairs. One technician should observe
the conditions of wheels or wheel stopper outside the vehicle while the other is doing the test.

Be careful to prevent SST's hose from interfering with the exhaust pipe.
(1) Warm up the ATF.
(2) Remove the test plug on the front side of the trans-
axle case and connect SST.
SST 09992-00095 (09992- 00231, 09992-00271)
(3) Fully apply the parking brake and chock the 4
wheels.
(4) Connect an OBD II scan tool or hand-held tester to
the DLC3.
(5) Start the engine and check idling speed.
(6) Keep your left foot pressing firmly on the brake ped-
al and shift into D position.
(7) Measure the line pressure when the engine is idling.
(8) Depress the accelerator pedal all the way down.
Quickly read the highest line pressure when engine
speed reaches stall speed.
(9) In the same way, do the test in R position.
Specified line pressure:
ConditionD position kPa (kgf / cm2, psi)R position kPa (kgf / cm2, psi)
Idling372 to 412 kPa
(3.8 to 4.2 kgf/cm2, 54 to 60 psi)

MECHANICAL SYSTEM TESTS
1. PERFORM MECHANICAL SYSTEM TESTS
(a) Measure the stall speed.
The object of this test is to check the overall performance of the transaxle and engine by measuring
the stall speeds in the D and R positions.
NOTICE:

Perform the test at the normal operating ATF (Automatic Transmission Fluid) temperature 50
to 80°C (122 to 176°F).

Do not continuously run this test for longer than 10 seconds.

To ensure safety, do this test in a wide, clear level area which provides good traction.

The stall test should always be carried out in pairs. One technician should observe the condi-
tions of wheels or wheel stoppers outside the vehicle while the other is doing the test.
(1) Chock the 4 wheels.
(2) Connect an OBD II scan tool or hand-held tester to the DLC3.
(3) Fully apply the parking brake.
(4) Keep your left foot pressed firmly on the brake pedal.
(5) Start the engine.
(6) Shift into the D position. Press all the way down on the accelerator pedal with your right foot.
(7) Quickly read the stall speed at this time.
Stall speed: 2,250
150 rpm
(8) Do the same test in the R position.
Stall speed: 2,250
150 rpm
Evaluation:
ProblemPossible cause
(a) Stall engine speed is low in D and R positions

Engine power output may be insufficient

Stator one-way clutch not operating properly
HINT: If the value is less than the specified value by 600 rpm or
more, the torque converter could be faulty.
(b) Stall engine speed is high in D position

Line pressure is too low

Forward clutch slipping

No. 2 one-way clutch not operating properly

U/D (Underdrive) clutch slipping
(c) Stall engine speed is high in R position

Line pressure is too low

U/D (Underdrive) clutch slipping
(d) Stall engine speed is high in D and R positions

Line pressure is too low

Improper fluid level
