GM Service Manual Online
For 1990-2009 cars only

The Driver Information Center (DIC) gives you the status of many of your vehicle's systems. The DIC is also used to display warning/status messages. All messages will appear in the DIC display located at the bottom of the instrument panel cluster, below the tachometer and speedometer. The DIC buttons are located on the instrument panel, to the left of the steering wheel.

The DIC comes on when the ignition is on. After a short delay, the DIC will display the current driver and the information that was last displayed before the engine was turned off.

The top line of the DIC display shows the vehicle system information and the warning/status messages. The bottom line of the DIC display shows either the odometer, the trip odometer A or the trip odometer B information on the left side. Only one odometer can appear at a time. See "Trip Information" under DIC Operation and Displays for information on changing the display to show the odometer or trip odometer information. The bottom line of the DIC display also shows the outside temperature on the right side and the shift lever position indicator in the center. See Automatic Transmission Operation for more information on the shift lever positions.

When the sport mode is active, an S will appear next to the shift position indicator on the center of the DIC display. When the manual mode is active, an M will appear on the DIC display. When the normal mode is active, only the shift position indicator will appear. While the Driver Shift Control (DSC) feature is active, the DIC will change to show the selected gear. See "Driver Shift Control (DSC)" under Automatic Transmission Operation for more information.

If a problem is detected, a warning message will appear on the display. Be sure to take any message that appears on the display seriously and remember that clearing the message will only make the message disappear, not correct the problem.
