  1. Start the engine and allow the engine to idle for approximately 5 minutes. If possible drive the vehicle for a few kilometers (miles) to warm the transaxle fluid.
  2. Inspect the fluid level when the transaxle temperature is greater than 30°C (86°F).

  3. Object Number: 1290873  Size: SH

  7. Raise and suitably support the vehicle.
  8. Place a fluid container below the fluid level plug.
  9. Warning: When the transmission is at operating temperatures, take necessary precautions when removing the check/fill plug, to avoid being burned by draining fluid.

  10. Using DT 46475  (1) remove the fluid level plug. Because the transaxle operates correctly over a range of levels, fluid may not drain out of the plug hole when the plug is removed.

  11. Object Number: 1255913  Size: SH
  12. Inspect the oil fluid level.
  13. If fluid does not drain through the plug hole after adding a total of 4 liters, then either the transaxle was underfilled or the transaxle is leaking fluid. Inspect the transaxle for fluid leaks. Fix any leaks before setting the transaxle fluid level. Refer to Fluid Level Set After Service.
  14. Caution: Refer to Fastener Caution in the Preface section.


    Object Number: 1255914  Size: SH
  15. Using DT 46475  (1) install the fluid level plug and tighten to 45 N·m (33 lb ft).
  16. When the procedure is completed, wipe any fluid from the transaxle case with a rag or a shop towel. Verify that the fluid fill cap and the vent tube are properly installed.

Fluid Level Set After Service

  1. Add transaxle fluid through the fill cap hole prior to adjusting the fluid level. The amount of fluid to add should be based on the type of service done. For the proper fluid level, refer to Fluid Capacity Specifications.
  2. Inspect the transaxle fluid level using the procedure above.
  3. Add additional fluid through the fill cap hole in 0.5L (0.5 qt) increments until the fluid comes out through the plug hole.
  4. Allow the fluid to finish draining out through the plug hole. Install the fluid level plug.
  5. When the procedure is completed, wipe any fluid from the transaxle case with a rag or a shop towel. Verify that the fluid fill cap and the vent tube are properly installed.
