Cadillac 2009 owner manual Change Engine OIL Soon, Engine HOT A/C Air Conditioning

Some messages cannot be cleared from the DIC display because they are more urgent. These messages require action before they can be cleared. You should take any messages that appear on the display seriously and remember that clearing the messages will only make the messages disappear, not correct the problem.

The following are the possible messages that can be displayed and some information about them.

CHANGE ENGINE OIL SOON

This message displays when the engine oil needs to be changed. When you change the engine oil, be sure

to reset the CHANGE ENGINE OIL SOON message. See Engine Oil Life System on page 6-18for information on how to reset the message. See Engine Oil on page 6-15and Scheduled Maintenance on page 7-4for more information.

CHECK TIRE PRESSURE

On vehicles with the Tire Pressure Monitor System (TPMS), this message displays when the pressure in one or more of the vehicle’s tires needs to be checked. This message also displays LEFT FRONT, RIGHT FRONT, LEFT REAR, or RIGHT REAR to indicate which tire needs to be checked. You can receive more than one tire pressure message at a time. To read the other messages that may have been sent at the same

time, press the set/reset button. If a tire pressure message appears on the DIC, stop as soon as you can.

Have the tire pressures checked and set to those shown on the Tire Loading Information label. See Tires on page 6-54, Loading the Vehicle on page 5-31, and Inflation - Tire Pressure on page 6-60. The DIC also shows the tire pressure values. See DIC Operation and Displays on page 3-42. If the tire pressure is low, the low tire pressure warning light comes on. See Tire Pressure Light on page 3-35.

DRIVER DOOR OPEN

This message displays and a chime sounds if the driver door is not fully closed and the vehicle is shifted out

of P (Park). Stop and turn off the vehicle, check the door for obstructions, and close the door again. Check to see if the message still appears on the DIC.

ENGINE HOT A/C (Air Conditioning)

TURNED OFF

This message displays when the engine coolant becomes hotter than the normal operating temperature. See Engine Coolant Temperature Gage on page 3-35. To avoid added strain on a hot engine, the air conditioning compressor automatically turns off. When the coolant temperature returns to normal, the air conditioning compressor turns back on. You can continue to drive your vehicle.

If this message continues to appear, have the system repaired by your dealer/retailer as soon as possible to avoid damage to the engine.
