GM Service Manual Online
For 1990-2009 cars only

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.

If a problem is detected, a warning message will appear on the display. Pressing the trip stem will acknowledge any warning or service messages. Pressing any of the DIC steering wheel buttons (Trip Information, Fuel Information, Personalization or Select button) will also acknowledge any warnings or service messages.

The DIC has different modes which can be accessed by pressing the four buttons on the DIC. These buttons are trip information, fuel information, personalization and select. The button functions are detailed following.

Trip Information

Use the trip information button to scroll through the odometer, TRIP A, TRIP B and TIMER.

Odometer

Press the trip information button until the odometer appears on the display. This shows the total distance the vehicle has been driven in either miles or kilometers. Pressing the reset stem located on the instrument cluster with the vehicle off will also display the odometer.

Trip A and Trip B

Press the trip information button until TRIP A or TRIP B is displayed. This shows the current distance traveled since the last reset for each trip odometer in either miles or kilometers. Both odometers can be used at the same time.

Each trip odometer can be reset to zero separately by pressing select while the desired trip odometer is displayed. You can also reset the trip odometers with the reset stem on the cluster. If you press and hold the reset stem for four seconds, the display will show the distance traveled since the last ignition cycle.

Timer

The DIC can be used as a stopwatch. Press the select button while TIMER is displayed to start the timer. The display will show the amount of time that has passed since the timer was last reset (not including time the ignition is off). Time will continue to be counted as long as the ignition is on, even if another display is being shown on the DIC. The timer will record up to 99 hours, 59 minutes and 59 seconds (99:59:59) after which the display will roll back to zero.

To stop the counting of time, press the select button briefly while TIMER is displayed.

Average Fuel Economy

Press the fuel information button until AVG appears in the display. Average fuel economy is how many miles per gallon your vehicle is getting based on current and past driving conditions.
