DIC Warnings and Messages
Warning messages are displayed on the Driver
Information Center (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.
More than one message may appear at one time. They
will appear one after the other. The messages are
displayed for four seconds each. Some messages may
not require immediate action but you should press and
release the trip odometer reset stem to acknowledge that
you received the message and clear it from the display.
Each message must be acknowledged individually. Some
messages cannot be cleared from the display because
they are more urgent. These messages require action
before they can be removed from the DIC display. 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.
AC (Air Conditioning) OFF
This message will be displayed when the engine coolant
temperature is too high and the air conditioning in
your vehicle needs to be turned off. See Engine
Overheating on page 5-27 and Climate Control System
on page 3-21 for more information. This message
will be displayed along with the ENG HOT message.
