5-30 Instruments and Controls Cruise Control Light Information Displays Driver Information Center (DIC) The vehicle has a Driver Information Center (DIC). The DIC displays information about this 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. The DIC has different displays which can be accessed by pressing the DIC buttons located on the instrument panel, next to the steering wheel. If the vehicle does not have DIC buttons, the trip odometer reset stem can be used to access some of the menu items. The DIC displays trip, fuel, and vehicle system information, and warning messages if a system problem is detected. The DIC also allows some features to be customized. See Vehicle Personalization (With DIC Buttons) on page 5‑48 for more information. If the vehicle has a diesel engine, see the Duramax® diesel supplement for more information. For vehicles equipped with cruise control, this light comes on whenever the cruise control is set. The light goes out when the cruise control is turned off. See Cruise Control on page 9‑58 for more information.
