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.
If there is more than one message that needs to
be displayed, they will appear one after another. Some
messages may not require immediate action, but
you should press any of the four DIC buttons on the
steering wheel, if equipped, to acknowledge that
you received the messages and clear them from the
display. If your vehicle is not equipped with DIC buttons
on the steering wheel, press the trip odometer reset
stem located on the instrument panel cluster to

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

the display seriously and remember that clearing the
messages will only make the messages disappear, not
correct the problem. The following are the possible
