Press the Set/Reset button and hold for two seconds to clear the CHANGE ENGINE OIL SOON message and reset the oil life at 100%. Be careful not to reset the oil life display accidentally at any time other than after the oil is changed. It cannot be reset accurately until the next oil change. Automatic Transmission Fluid How to Check 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. The vehicle is not equipped with a transmission fluid level dipstick. There is a special procedure for checking and changing the transmission fluid. Because this procedure is difficult, it should be done at the dealer. Contact your dealer for additional information or refer to the procedure in the service manual. To purchase a service manual, see Service Publications Ordering Information on page 13￿18.
