Automatic Transmission Fluid
It is not necessary to check the transmission fluid level.
A transmission fluid leak is the only reason for fluid loss. If a leak occurs, take the vehicle to the dealer and have it repaired as soon as possible.
Change the fluid at the intervals listed in Maintenance Schedule on page 11‑3, and be sure to use the transmission fluid listed in Recommended Fluids and Lubricants on page 11‑12.
Notice: Use of the incorrect automatic transmission fluid may damage the vehicle, and the damages may not be covered by the vehicle warranty.
Always use the automatic transmission fluid listed in Recommended Fluids and Lubricants on page 11‑12.
The transmission fluid will not reach the end of the dipstick unless the transmission is at operating temperature. If you need to check the transmission fluid level, please take the vehicle to your dealer.
