Vehicle Messages
Messages are displayed on the 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 instrument panel or the trip odometer reset stem on the instrument panel cluster to acknowledge that you received the messages and to clear them from the display.
Some messages cannot be cleared from the DIC display because they are more urgent.
These messages require action before they can be cleared.
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.
