GM Service Manual Online
For 1990-2009 cars only

Messages are displayed on the uplevel 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 on the uplevel vehicle 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.

This message will display when the engine coolant becomes hotter than the normal operating temperature. See Engine Coolant Temperature Gage .
