Warning
• When performing a road test, be aware of other vehicles, people, impediments, etc. to avoid an
accident.
Note
• When the legal speed limit must be exceeded, use a chassis dynamomenter instead of performing a road
test.
Road Test Preparation
1. Inspect the engine coolant levels. (See
E–3 ENGINE COOLANT LEVEL INSPECTION
2. Inspect the engine oil levels. (See
.)
3. Inspect the ATF levels. (See
K–12 AUTOMATIC TRANSAXLE FLUID (ATF) INSPECTION
4. Inspect the idle speed and ignition timing in P position. (See
.)(See
5. Bring up the engine and transaxle to normal operating temperature.

P Position Test
1. Shift into P position on a gentle slope. Release the brake and verify that the vehicle does not roll.

AUTOMATIC TRANSAXLE FLUID (ATF) INSPECTION
A6E561401030W03
Automatic Transaxle Fluid (ATF) Condition Inspection
1. One way of determining whether the transaxle should be disassembled is by noting:
• If the ATF is muddy or varnished.
• If the ATF smells strange or unusual.
ATF Condition
Automatic Transaxle Fluid (ATF) Level Inspection
Caution
• The ATF amount varies according to ATF's temperature. Therefore, when checking the ATF level or
replacing the ATF, use a thermometer to measure the temperature then adjust the ATF amount to
the specified level according to the specified temperature.
1. Park the vehicle on level ground.
2. Apply the parking brake and position wheel chocks securely to prevent the vehicle from rolling.
3. Adjust the length or thermistor probe to measure
the same depth as the depth gauge and hold the
probe with a paper holder. Insert into the filler
tube and measure the temperature.
• If necessary, inspect the ATF before warming
up the engine. In this case, use the cool
range.15—25
°C {59—77 °F}
4. Warm up the engine until the ATF reaches 60—70
°C {140—158 °F}.
5. Shift the selector lever and pause momentarily in
each range (D—L) while depressing the brake
pedal.
6. Shift the selector lever to P position.
7. Verify that the ATF level is in the HOT range (65
°C{149 °F}) while the engine is idling.
• If necessary, add ATF to the specification.

Light red: pink
Contaminated
with water
• Broken oil cooler inside of radiator
• Poor filler tube installation:
Problem could be occurring to parts inside the transaxle by
water contamination. It is necessary to overhaul transaxle and
detect defected parts. If necessary, exchange transaxle.

Has burnt smell and metal
specks are found
Deteriorated
ATF
Defect powertrain components inside of transaxle: Specks
cause wide range of problems by plugging up in oil pipe, control
valve body and oil cooler in radiator.
• When large amount of metal specks are found, overhaul
transaxle and detect defected parts. If necessary, exchange
transaxle.
• Implement flushing operation as there is a possibility to have
specks plugging up oil pipe and/or oil cooler inside of
radiator.
Has no burnt smell

• Discoloration by oxidation
