Your vehicle has a Driver Information Center (DIC).
The DIC displays information about your vehicle. It also displays warning messages if a system problem is detected.
All messages will appear in the DIC display located below the tachometer in the instrument panel cluster.
The DIC comes on when the ignition is on. After a short delay, the DIC will display the information that was last displayed before the engine was turned off.
If your vehicle has DIC buttons, see "DIC Operation and Displays (With DIC Buttons)" later in this section and DIC Vehicle Customization for the displays available.
If your vehicle does not have DIC buttons, see "DIC Operation and Displays (Without DIC Buttons)" later in this section for the displays available.
Tahoe Police Package and Special Service Package
The Tahoe Police Package and Special Service Packages do not have DIC buttons. You can turn off or acknowledge the available DIC messages by using the trip odometer reset stem located on the instrument panel cluster. See your owner's manual for additional information on the DIC.

If there is a problem with the battery charging system, the DIC will display a message. See DIC Warnings and Messages.
