Engine Oil Life

The IPC displays the engine oil life remaining percent based on serial data messages from the ECM. The instrument panel cluster (IPC) displays the current percent of the GM Oil Life System in the trip odometer display. When the oil needs changing the change oil indicator in the message center turns on. When the engine oil is changed the oil life percent needs to be reset. Press and hold the set/reset button for 3 seconds until 100 percent is displayed in the trip odometer.
