DIC Warnings and Messages These messages will appear if there is a problem in one of the vehicle's systems. They will override any other mode or screen the DIC may be in. Some messages allow you to erase them from the DIC screen. To do this you must acknowledge the message. To acknowledge or clear the message from the screen, press the set/reset button on the DIC. See DIC Controls and Displays on page 3-45 for DIC button descriptions. Other warning messages are not allowed to be erased until the problem indicated by the warning message is taken care of. When the problem indicated by the message is resolved, it can be acknowledged and the screen can be reset. Be sure to take any message that appears on the DIC screen seriously and remember that clearing the messages that are able to be acknowledged, will only make the message disappear, not the problem. A/C OFF FOR ENGINE PROTECTION This warning message appears when the engine coolant becomes hotter than the normal operating temperature. To avoid added strain on a hot engine, the air conditioning compressor is automatically turned off. When the coolant temperature returns to normal, the air conditioning compressor will turn back on. You can continue to drive your vehicle. This warning message will display while the ignition is in RUN. A chime will sound for two seconds when this message is displayed. Press the set/reset button to acknowledge this warning message and to clear it from the screen. This message will continue to display if it has not been acknowledged when the engine is turned off. It will also re-display for three seconds if the message has been acknowledged, but the condition still exists when the engine is turned off. The message will re-appear when the engine is turned on and the condition still exists. 3-65
