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
