For 1990-2009 cars only

Your vehicle may have a Driver Information Center (DIC).

All messages will appear in the DIC display located in the instrument panel cluster, below the speedometer. The DIC buttons are located on the center of the instrument panel, below the center outlets.

The DIC comes on when the ignition is on. After a short delay, the uplevel DIC will display the WELCOME DRIVER (1 or 2) if a personalized key 1 or 2 is used, and then the information that was last displayed before the engine was turned off.

The base level DIC displays the odometer and trip odometers only.

The uplevel DIC displays the odometer, trip odometers, fuel economy, trip computer, vehicle system, and compass display information. It also displays warning messages if a system problem is detected. In addition, the uplevel DIC displays phone numbers that are called using the OnStar® system, if equipped. See OnStar® System .

The outside air temperature automatically appears in the bottom right corner of the uplevel DIC display when viewing the trip/odometer screens, fuel screens and some of the gages screens. If the outside air temperature is at or below 37°F (3°C), the temperature reading will toggle between displaying the outside temperature and the word ICE for two minutes. If there is a problem with the system that controls the temperature display, the letters OC (open circuit) or SC (short circuit) will appear on the display. If this occurs, have the vehicle serviced by your dealer/retailer.

The uplevel DIC also allows some features to be customized or personalized. See DIC Vehicle Personalization for more information.
