Change Engine Oil Soon

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2007 GMC Yukon XL, 2007 GMC Yukon, 2007 Chevrolet Tahoe, 2007 Chevrolet Suburban, and 2007 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

The instrument panel cluster (IPC) illuminates the CHANGE ENGINE OIL SOON message when the engine control module (ECM) determines that the engine oil should be changed. The IPC receives a class 2 message from the ECM requesting illumination. Once the oil is changed, perform the engine oil monitor reset procedure in order to clear the Change Engine Oil indicator. Refer to GM Oil Life System Resetting .
