Change Engine Oil Now
WARNING: This page is about a different car, the 2003 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
The IPC illuminates the CHANGE OIL NOW message in the driver information center (DIC) when the powertrain control module (PCM) determines that the engine oil needs to be changed now. The PCM sends a class 2 message to the IPC requesting illumination. After the oil is changed, reset the engine oil monitor. Refer to CHANGE ENGINE OIL LIGHT (PASSENGER CARS) .
