For 1990-2009 cars only

It is not necessary to check the transaxle fluid level. If a leak occurs, take the vehicle to the dealership service department and have it repaired as soon as possible.

Have your dealer or service center change both the fluid and filter every 50,000 miles (83 000 km) if the vehicle is mainly driven under one or more of these conditions:

    • In heavy city traffic where the outside temperature regularly reaches 90°F (32°C) or higher.
    • In hilly or mountainous terrain.
    • Uses such as found in taxi, police or delivery service.

If you do not use your vehicle under any of these conditions, the fluid and filter do not require changing.

Notice: Use of automatic transaxle fluid labeled other than ESSO LT71141 or TOTAL ATF H50235 may damage your vehicle, and the damages may not be covered by your warranty. Always use ESSO LT71141 or TOTAL ATF H50235 labeled automatic transaxle fluid.
