Change Oil Soon
WARNING: This page is about a different car, the 2004 Pontiac Grand Prix. However, it is still accessible from the selected car via links, so may be relevant.
The DIC illuminates the CHANGE OIL SOON message in the driver information center (DIC) when the PCM determines that the engine oil life is less than 5 percent. The PCM sends a class 2 message to the DIC requesting illumination. After the oil is changed, reset the engine oil monitor. Refer to Driver Information Center (DIC) Description and Operation in Instrument Panel, Gages, and Console.
