For 1990-2009 cars

When the system has calculated that oil life has been diminished, it will indicate that an oil change is necessary. A CHANGE ENGINE OIL light 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.

### How to Reset the Engine Oil Life System

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.

1. Press the vehicle information button on the driver information center (DIC) until OIL LIFE REMAINING displays.
2. Press and hold the Set/Reset button on the DIC for more than 5 seconds. The oil life will change to 100 percent.

If the light or message comes back on and stays on when you start the vehicle, the Engine Oil Life System has not reset. Repeat the procedure.
