OIL PRESSURE LOW If low oil pressure levels occur, this message will be displayed on the DIC and a chime will sound. Stop the vehicle as soon as safely possible and do not operate it until the cause of the low oil pressure has been corrected. Check your oil as soon as possible and have your vehicle serviced by your GM dealer. On the SUT, if the midgate is open or one or both of the midgate latches are not fully closed, this message will appear on the DIC. Turn off the vehicle and check that the midgate and the latches are closed. Restart the vehicle and check for the message on the DIC display. Pressing any of the four DIC buttons or the trip odometer reset stem will clear the message from the DIC display. PASSENGER DOOR AJAR If the passenger's door is not fully closed and the vehicle is in a drive gear, this message will appear on the display and you will hear a chime.

Pressing any of the four DIC buttons or the trip odometer reset stem will clear the message from the DIC display. REDUCED ENGINE POWER This message is displayed when the cooling system temperature gets too hot and the engine further enters the engine coolant protection mode.
