Change Engine Oil Soon

The driver information center displays the Change Engine Oil Soon message when the engine control module (ECM) determines that the engine oil life is below 5%. The ECM sends a serial data message to the instrument cluster requesting the Change Engine Oil Soon message. After the oil is changed, reset the engine oil monitor. 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 message displays in the driver information center 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. If ignored it 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 instrument cluster because of the Low Engine Oil Level/Change Engine Oil Soon message staying ON after an oil change or engine oil addition, it is necessary for the engine to undergo a thermodynamic cycle process. The instrument cluster may not be malfunctioning but only needs the Low Engine Oil Level/Change Engine Oil Soon to turn OFF. After the oil is changed, reset the engine oil monitor.
