When the system has calculated that oil life has been diminished, it will indicate that an oil change is necessary. A CHANGE ENGINE OIL SOON message will come on. Change the engine oil as soon as possible within the next 1 000 km (600 miles). It is possible that, if driving under the best conditions, the oil life system 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 5 000 km (3,000 miles) since last oil change.

The Engine Oil Life System calculates when to change the engine oil and filter based on vehicle use. Anytime the oil is changed, reset the system so it can calculate when the next oil change is required. If a situation occurs where the oil is changed prior to a CHANGE ENGINE OIL SOON message being turned on, reset the system.

If the vehicle does not have a Driver Information Center (DIC), do the following:

1. Turn the ignition to ON, with the engine OFF.
2. Fully press and release the accelerator pedal slowly three times within five seconds.
3. Turn the key to OFF. If the CHANGE ENGINE OIL SOON message comes back on when you start the vehicle, the engine oil life system has not reset. Repeat the procedure.

If the vehicle has a DIC, do the following:

1. Turn the ignition to ON, with the engine OFF.
2. Press the MODE button until the DIC reads OIL LIFE LEFT/HOLD SET TO RESET.
3. Press and hold the SET button until 100 percent is displayed. You will hear three chimes and the CHANGE ENGINE OIL SOON message will go off.
4. Turn the key to OFF.

If the CHANGE ENGINE OIL SOON message comes back on when you start the vehicle, the engine oil life system has not reset. Repeat the procedure.
