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. More than one message may appear at one time. They will appear one after the other. Some messages may not require immediate action, but you should press the trip stem on the instrument panel cluster to acknowledge that you received the message and to clear it from the display. Pressing any of the DIC steering wheel buttons -- trip information, fuel information, customization, or select button -- will also acknowledge any warnings or service messages. 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. The following are the possible messages that can be displayed and some information about them.

See If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow . To turn the StabiliTrak® system back on, press the StabiliTrak® button again.

There are several conditions that can cause this message to appear.
