GM Service Manual Online
For 1990-2009 cars only

Your vehicle has a Driver Information Center (DIC).

All information appears in the DIC display located in the instrument panel cluster.

The DIC comes on when the ignition is on. After a short delay, the DIC displays the information that was last displayed before the engine was turned off.

The DIC displays trip, fuel, and vehicle system information, and warning messages if a system problem is detected.

The DIC also displays the compass direction, outside air temperature, and shift position indicator at the top of the DIC display. If there is a problem with the system that controls the temperature display, the numbers will be replaced with dashes. If this occurs, have the vehicle serviced by your dealer/retailer. If an abnormal temperature reading is displayed for an extended period of time, consult your dealer/retailer. Under certain circumstances, especially when the engine is idling, a delay updating the temperature display is normal.

See DIC Compass and Automatic Transmission Operation for more information.
