Vehicle Care How to Reset the Engine Oil Life System Reset the system whenever the engine oil is changed so that the system can calculate the next engine oil change. To reset the system: 1. Turn the ignition to ON/RUN with the engine off. 2. Fully press and release the accelerator pedal three times within five seconds. If the "Change Engine Oil Soon" message is not on, the system is reset. The system is reset when the "Change Engine Oil Soon" message is off. 9-13 What to Do with Used Oil Used engine oil contains elements that can be unhealthy for your skin and could even cause cancer. Do not let used oil stay on your skin. Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly dispose of clothing or rags. See the manufacturer's warnings about the use and disposal of oil products. Used oil can be a threat to the environment. If you change your own oil, be sure to drain all the oil from the filter before disposal. Never dispose of oil by putting it in the trash, pouring it on the ground, into sewers, or into streams or bodies of water. Recycle it by taking it to a place that collects used oil. 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/retailer service department and have it repaired as soon as possible. There is a special procedure for checking and changing the transmission fluid. Because this procedure is difficult, it should be done at the dealer/retailer service department. Contact your dealer/ retailer for additional information or the procedure can be found in the service manual. To purchase a service manual, see Service Publications Ordering Information on page 12‑12.
