ATF condition





Transaxle Fluid (ATF) Level Inspection

CAUTION:
- If the ATF level is not within the specification, do not drive the vehicle. Otherwise, the transaxle could be damaged.
- If there is no ATF adhering to the dipstick after warming up the engine, there is insufficient ATF. Therefore do not drive the vehicle as it could damage the transaxle.
- If too much ATF is added, the ATF temperature will increase and oil could leak from the breather hose.

1. Park the vehicle on level ground, and then engage the parking brake and use wheel chocks at the front and rear of the wheels.

2. Verify visually that there is no ATF leakage from the oil hose or housing.

3. Connect the M-MDS to the DLC-2.

4. Start the engine and warm it up in the P position.

CAUTION:
- If the oil level decreases dramatically while warming-up the engine, do not shift the selector lever as it could damage the transaxle.

5. Verify that the ATF temperature is 60-70 °C {140-158 °F} using the M-MDS.

6. Shift the selector lever and pause momentarily in each position (P-1) while depressing the brake pedal.

7. Shift the selector lever to the P position.

8. Remove the dipstick and wipe it clean while the engine is idling.

9. Install the dipstick and remove it again.

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






- If the ATF level is out of the range, adjust the ATF to the specification.
