DIC Warnings and Messages
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
ve 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.
SeeEngine Coolant Temperature Gage on page 3-41.

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.

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.
