GM Service Manual Online
For 1990-2009 cars only

This vehicle has the GM Oil Life System ™. The system will show when to change the engine oil and oil filter. This will usually occur between 5 000 km (3,000 mi) and 12 500 km (7,500 mi) since the last oil change. Under severe conditions, the indicator may come on before 5 000 km (3,000 mi).

Vehicle should not be driven more than 12 500 km (7,500 mi) or 12 months without an oil and oil filter change. The system won't detect dust in the oil. So if the vehicle is driven in a dusty area, be sure to change the oil and oil filter every 5 000 km (3,000 mi) or sooner if the CHANGE OIL SOON indicator comes on. Reset the monitor when the oil has been changed.

  2. Fully press and release the accelerator pedal three times within 10 seconds.
  3. If the CHNGE OIL light flashes for five seconds, the system is reset.
