System for calculating oil's service life, resetting
When the system has calculated that oil life has been diminished, it will indicate that an oil change is necessary. A CHANGE message will come on. Change the engine oil as soon as possible within the next 600 miles (1000 km). It is possible that, if driving under the best conditions, the oil life may not indicate that an oil change is necessary for over a year. However, the engine oil and filter must be changed at least once a year and at this time the system must be reset.
If the system is ever reset accidentally, change the engine oil at 3000 miles (5000 km) since last oil change.
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
- Using the Driver Information Center (DIC) MENU button and thumbwheel on the turn signal lever, display REMAINING OIL LIFE on the DIC.
- Press the SET/CLR button to 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.
The oil life system can also be reset as follows
- Turn the ignition to ON with the engine OFF.
- Fully press and release the accelerator pedal 3 times within 5 seconds.
If the CHANGE ENGINE OIL SOON message is not on, the system is reset.
If the CHANGE ENGINE OIL SOON message comes back on when the vehicle is started, the engine oil life system has not been reset. Repeat the procedure.
