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 OIL LOW ADD OIL If your vehicle has an oil level sensor, this message displays if the oil level in the vehicle is low. Check the oil level and correct it as necessary. You may need to let the vehicle cool or warm up and cycle the ignition to be sure this message clears. This message clears itself after 10 seconds, until the next ignition cycle. See Engine Oil on page 459 for additional information. 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 252. To avoid added strain on a hot engine, the air conditioning compressor automatically turns off.

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