CHANGE ENGINE OIL SOON	The driver information center (DIC) displays the CHANGE ENGINE OIL message when the engine control module (ECM) determines that the engine oil life drops below 5 percent. The ECM sends a GMLAN message to the instrument panel cluster (IPC) requesting the CHANGE ENGINE OIL display. After the oil is changed, reset the engine oil monitor. Refer to GM Oil Life System Resetting . When the Low Engine Oil Level/Change Engine Oil Soon indicator displays in the IPC or DIC due to a low engine oil level condition, make sure that the ignition is turned OFF before adding or changing the oil in the vehicle. Failure to do so may result in the Low Engine Oil Level/Change Engine Oil Soon indicator or message staying on after the engine attains proper oil level. Before replacing the IPC because of the Low Engine Oil Level/Change Engine Oil Soon indicator staying ON after an oil change or engine oil addition, it is necessary for the engine to undergo a thermo cycle process. The IPC may not be malfunctioning but only needs the Low Engine Oil Level/Change Engine Oil Soon indicator to turn OFF after an engine thermo cycle process. Refer to GM Oil Life System Resetting .
