Engine Oil Low

The driver information center (DIC) displays ENGINE OIL LOW ADD OIL when the engine control module (ECM) detects a low engine oil level condition from the engine oil level sensor/switch. The instrument panel cluster (IPC) receives a GMLAN message indicating a low engine oil level condition. Refer to GM Oil Life System Resetting . Refer to the following before adding or changing engine oil:

• 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 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 staying ON after an oil change or engine oil addition, it is necessary for the engine to undergo a thermocycle process. The IPC may not be malfunctioning but only needs the Low Engine Oil Level/Change Engine Oil Soon to turned off. After the oil is changed, reset the engine oil monitor.
