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 or message staying on after the engine attains proper oil level.
• When the Low Engine Oil Level/Change Engine Oil Soon indicator displays in the IPC or DIC and the ignition is not turned OFF before adding or changing the engine oil, the Low Engine Oil Level/Change Engine Oil Soon indicator may stay ON even after the proper oil level is attained. For the Low Engine Oil Level/Change Engine Oil Soon to turn OFF, the engine has to undergo a thermocycle process, refer to Indicator/Warning Message Description and Operation . The description of the Low Engine Oil Level/Change Engine Oil Soon in this article will outline how to clear the indicator.
• 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 as stated above. The IPC may not be malfunctioning but only needs the Low Engine Oil Level/Change Engine Oil Soon turned off. Refer to Indicator/Warning Message Description and Operation  for an outline on how to clear the indicator.
