## Automatic Transaxle Fluid (ATF) Level Inspection

  Caution

  • The ATF amount varies according to ATF temperature. Therefore, when inspecting 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. Place 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.

  • Inspect the ATF before warming up the engine if necessary using the cool range15-25 °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 the P position.

7. Verify that the ATF level is in the HOT range (65 °C {149 °F}) while the engine is idling.

  • Add ATF to the specification If necessary.
