GM OIL LIFE SYSTEM RESETTING

The vehicle has a computer system that has a change engine oil message, indicating when to
change the engine oil and filter. This is based on engine revolutions and engine temperature and
not on mileage. Based on driving conditions, the kilometers or mileage at which an oil change
will be indicated can vary considerably. For the oil life system to work properly, the system must
be reset every time the oil is changed.

When the system has calculated that oil life has been diminished, it will indicate that an oil
change is necessary. The change engine oil message will come on. The oil must be changed as
soon as possible. It is possible that, if the vehicle is driven 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, the oil must be changed at 3,000 miles (5 000 km) since the last
oil change. Remember to reset the oil life system whenever the oil and filter is changed.

Resetting Procedure

1. Turn the ignition to RUN with the engine OFF.

2. Press and release the reset stem in the lower center of the instrument panel (I/P) cluster until

the OIL LIFE message is displayed.

3. Once the alternating OIL LIFE and RESET messages appears in the display, press and hold

the reset stem until several beeps sound. This confirms the OIL LIFE system has been reset.

2. Fully press the release the accelerator pedal 3 times within 5 seconds. Several beeps sound.

This confirms the oil life system has been reset.

3. If the CHANGE/OIL message comes back on when you start the engine, the engine oil life

system has not been reset. Repeat the procedure.
