Explanation of Maintenance Items
37
Differential Oil
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.
Drive Belts
Inspect for cracks, excessive wear and oiliness. Check the belt tension and
adjust if necessary. Replace the belts if they are damaged.
Drive Shaft Boots
Check the drive shaft boots and clamps for cracks, deterioration and damage.
Replace any deteriorated or damaged parts and, if necessary, repack the grease.
Selected models also require periodic inspection of the drive shaft bolt for proper
torque. A qualified technician should perform these operations.
Engine Air Filter
Replace at specified intervals. When performing inspections, check for damage,
excessive wear and oiliness, and replace if necessary.
Engine Coolant
Drain and flush the cooling system and refill with an ethyleneglycol type
coolant. Inspect the radiator, condenser and/or intercooler for leaves, dirt and
insects and clean if necessary. Inspect hoses and connections for corrosion and
leaks. Tighten connections and replace parts as necessary. A qualified technician
should perform these operations. (For further details, refer to “Radiator,
Condenser and Hoses” in the “Vehicle Maintenance and Care” section of the
Owner’s Manual.)
Note:YourToyota is equipped with Genuine Toyota Super LongLife Coolant. The
replacementintervals for engine coolant recommended in this booklet are based
on replacement with Genuine Toyota Super LongLife Coolant or similar high
quality nonsilicate, nonamine, nonborate ethyleneglycol coolant with
longlife hybrid organic acid technology (i.e., a combination of low phosphates
and organic acids). If another type of ethyleneglycol coolant is used, replacementintervals may be different.
Engine Oil and Oil Filter
Replace the oil filter and drain and refill the engine oil at specified intervals.
For recommended oil grade and viscosity, refer to the
Owner’s Manual.

ROAD TEST
1. PROBLEM SYMPTOM CONFIRMATION
(a) Based on the result of the customer problem analysis, try to reproduce the symptoms. If the problem
is that the transaxle does not shift up, shift down, or the shift point is too high or too low, conduct the
following road test referring to the automatic shift schedule and simulate the problem symptoms.
2. ROAD TEST
NOTICE:
Perform the test at the ATF (Automatic Transmission Fluid) temperature 50 to 80°C (122 to 176°F) in
the normal operation.
(a) D position test:
Shift into the D position and fully depress the accelerator pedal and check the following points.
(1) Check up-shift operation.
Check that 1 " 2, 2 " 3 and 3 " O/D up-shifts take place, and that the shift points conform to
the automatic shift schedule (see page 03-51).
HINT:
O/D Gear Up-shift Prohibition Control
Engine coolant temperature is 60 °C (140 °F) or less and vehicle speed is at 70 km/h (43 mph) or less.
ATF temperature is 10 °C (50 °F) or less.
O/D Gear Lock-up Prohibition Control
Brake pedal is depressed.
Accelerator pedal is released.
Engine coolant temperature is 60 °C (140 °F) or less.
(2) Check for shift shock and slip.
Check for shock and slip at the 1 " 2, 2 " 3 and 3 " O/D up-shifts.
(3) Check for abnormal noise and vibration.
Check for abnormal noise and vibration when up-shifting from 1 " 2, 2 " 3 and 3 " O/D while
driving with the shift lever in the D position, and check while driving in the lock-up condition.
HINT:
The check for the cause of abnormal noise and vibration must be done thoroughly as it could also be due
to loss of balance in the differential, torque converter clutch, etc.
(4) Check kick-down operation.
Check vehicle speeds when the 2nd to 1st, 3rd to 2nd and O/D to 3rd kick-downs take place
while driving with the shift lever in the D position. Confirm that each speed is within the applicable
vehicle speed range indicated in the automatic shift schedule (see page 03-51).
(5) Check abnormal shock and slip at kick-down.
(6) Check the lock-up mechanism.
Drive in D position (O/D gear), at a steady speed (lock-up ON).
Lightly depress the accelerator pedal and check that the engine speed does not change
abruptly.
HINT:
There is no lock-up function in the 1st and 2nd gear.
If there is a big jump in engine speed, there is no lock-up.
