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 acknowledge messages and clear them from the display.

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.
