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 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

To reset the Engine Oil Life System, do the following:

1. Turn the ignition to RUN, with the engine OFF.
2. Fully press and release the accelerator pedal 3 times within 5 seconds.

If the Change Oil light flashes, the system has been reset. The light will flash for up to 30 seconds or until the ignition is turned OFF.

If the light comes on again and stays on for 30 seconds at the next ignition cycle, the system did not reset. Reset the system again.
