  15. With the transaxle in PARK, the vehicle on a level surface, the engine at idle (680-780 rpm) and foot pressed on the brake, move the selector lever through each gear and allow engagement of each gear. Place the selector lever back in the PARK position.
  16. Wipe the transmission fluid level indicator cap and remove the transmission fluid level indicator.
  17. Wipe the transmission fluid level indicator with a clean cloth.
    18. NOTE: In order to get an accurate transmission fluid level reading, the vehicle should be on a level surface. Idle the engine to reach the normal operating temperature. Using the scan tool, verify that the transaxle is at normal operating temperature 60°C-70°C (140°F-158°F), prior to adjusting the transmission fluid level.
  18. If transmission fluid needs to be added, add transmission fluid in 0.25L (1/2 pt) increments through the transmission fluid fill plug located on the top of the transaxle near the transmission fluid level indicator. Do not overfill the transmission fluid. Install the transmission fluid level indicator back in the transmission fluid filler tube until it is fully seated, then remove the transmission fluid level indicator. The transmission fluid level should be at the upper most mark on the transmission fluid level indicator. Only fill to the upper most mark on the transmission fluid level indicator. Do not overfill. Damage to the transaxle will occur.

    NOTE: The correct transmission fluid level at normal operating temperature of 60°C-70°C (140°F-158°F) is between the top 2 marks on the transmission fluid level indicator.
  19. Fill the transaxle to the correct transmission fluid level.

    NOTE: The correct transmission fluid level at cool operating temperature of 15°C-25°C (59°F-77°F), is at the bottom mark on the transmission fluid level indicator.
  20. If the TFT is low, fill the transaxle with transmission fluid to the cold range on the transmission fluid level indicator. Recheck the transmission fluid level when the transaxle has reached the normal operating temperature.
