Buick 2006 manual DIC Warnings and Messages, OFF for Engine Protection

DIC Warnings and Messages

Messages are displayed on the DIC to notify the driver that the status of the vehicle has changed and that some action may be needed by the driver to correct the condition. Multiple messages may appear one after another.

Some messages may not require immediate action, but you can press any of the DIC buttons to acknowledge that you received the message and clear it from the DIC display.

Some messages cannot be cleared from the DIC display because they are more urgent. These messages require action before they can be cleared.

If there are any active warning messages when the vehicle is turned off, two chimes will sound and the DIC will go into a reminder mode. The reminder mode displays any active message. If there are multiple messages, the DIC will display each message for

five seconds. After each active message is displayed once, the reminder mode will turn off.

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.

A/C OFF FOR ENGINE PROTECTION

This message will display when the engine coolant becomes hotter than the normal operating temperature. See Engine Coolant Temperature Gage on page 3-43. 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 message will come on while the ignition is in RUN. Press any of the DIC buttons to acknowledge this warning message and to clear it from the screen.

This message will continue to display for two seconds if it has not been acknowledged when the engine is turned off. It will also re-display for two seconds if the message has been acknowledged, but the condition still exists when the engine is turned off.

If the condition still exists, the message will re-appear when the engine is turned on. If this message continues to appear, have the system repaired by your GM dealer as soon as possible to avoid damage to your engine.
