GM Service Manual Online
For 1990-2009 cars only

Turn on the system by turning the ignition to ON. When you turn on the ignition, the DIC will be in the mode last displayed when the engine was turned off. Each DIC button allows you to scroll through a menu. A blank page ends each menu.

If a problem is detected, a diagnostic message will appear on the display. Press RESET to acknowledge any current warning or service messages. The following pages will show the messages you can see on the Driver Information Center (DIC) display by pressing the DIC buttons.

1 FUEL

The FUEL button displays average fuel economy and instantaneous fuel economy calculated for your specific driving conditions and range.


Object Number: 806298  Size: B3

Press the FUEL button to display average fuel economy, such as:

    • AVERAGE 20.1 MPG or
    • AVERAGE 5.3 L/100 km

The average fuel economy is viewed as a long-term approximation of your overall driving conditions. If you press RESET in this mode while you're driving, the system will begin figuring fuel economy from that point in time.

Press FUEL again to display instantaneous fuel economy, such as:

    • INST. 20.1 MPG or
    • INST. 5.3 L/100 km

Press FUEL again to display the range, such as:

    • RANGE 20 MI or
    • RANGE 32 km

The range calculates the remaining distance you can drive without refueling. It's based on fuel economy and the fuel remaining in the tank.

If the range is lower than 30 miles (48 km), the display will read RANGE LOW.

The fuel economy data used to determine fuel range is an average of recent driving conditions. As your driving conditions change, this data is gradually updated. Resetting the fuel range causes the fuel economy data to be updated immediately. Press RESET to reset the fuel range.

2 GAGES

The GAGES button allows you to scroll through the functions listed below when you press it.

Odometer

The odometer shows how far your vehicle has been driven in either miles or kilometers. Press the TRIP button to display odometer readings such as:

    • ODOMETER 12345 MI or
    • ODOMETER 20008 km

Without the keys in the ignition, you can also display the odometer by turning on the parking lamps.

Trip Odometers

There are two trip odometers. Press the TRIP button and TRIP A will be displayed. Press it again and TRIP B will be displayed. TRIP A could be used to track the distance to a destination. TRIP B could be used to track maintenance periods.

  2. TRIP A 209.9 km
  3. TRIP B 300.5 MI or
  4. TRIP B 483.5 km

The trip odometers can be reset by pressing the RESET button on the DIC. Both of the trip odometers can be used simultaneously.

Miles Since Last Ignition Feature

You can also display number of miles (kilometers) driven since you last started the vehicle if you press and hold the RESET button for two seconds, then release. The miles (or kilometers) since the last ignition cycle will be set into the trip odometer.

Elapsed Time

Press the TRIP button until ELAP. TIME is displayed, such as ELAP. TIME 00:00:00.00.

When the ignition is in ON, the Driver Information Center (DIC) can be used as a stopwatch. The display can show hours, minutes, seconds and hundredths of a second. The elapsed time indicator will record up to 99 hours, 59 minutes and 59 seconds, then it will reset to zero and continue counting. (Hundredths are shown up to 59 minutes, 59 seconds and 99 hundredths). The display appears as ELAP. TIME 00:00:00.00 in the elapsed time function.

You can start or stop the elapsed time by pressing RESET. To reset the elapsed time to zero, stop the timer by pressing RESET. Then press and hold RESET until ELAP. TIME 00:00:00.00 appears in the DIC.

Average Speed

Press the TRIP button until the average speed is displayed, such as:

    • AVERAGE SPEED 62 MPH or

Press reset in this mode to start calculating the average speed. Press and hold RESET to clear.

Engine Oil Life

Press the TRIP button until the engine oil life is displayed, such as OIL LIFE REMAIN 89%.

This is an estimate of the engine oil's remaining useful life. It will show 100% when the system is reset after an oil change. It will alert you to change your oil on a schedule consistent with your driving conditions.

When the remaining oil life is low, the system will alert you with the message CHANGE OIL SOON.

When the oil life is down to zero, you will receive the message CHANGE OIL NOW.

Remember, you must reset the OIL LIFE yourself after each oil change. It will not reset itself. Also, be careful not to reset the OIL LIFE accidentally at any time other than when the oil has just been changed. It can't be reset accurately until the next oil change.

To reset the system, see "How to Reset the Change Oil Soon Message" under Engine Oil .

Also, see Engine Oil and Scheduled Maintenance .

Blank Page

There is a blank page at the end of the OPTIONS menu. When the blank page is displayed, you can access the following items:

FOB TRAINING: This option allows you to match the RKE transmitter(s) to your vehicle. You can access this option by pressing and holding RESET for three seconds while you are on the blank page at the end of the OPTIONS menu. The message FOB TRAINING will be displayed. See "Matching Transmitter(s) To Your Vehicle" under Remote Keyless Entry (RKE) System Operation

TIRE TRAINING (Except Z06): The Tire Pressure Monitor (TPM) operates with battery-powered sensors that are located inside the valve stems on each tire. Each sensor has a unique ID code so the vehicle knows the tire location of the sensor. When the vehicle reaches a speed of greater than 15 mph (24 km/h), the sensors begin to send the tire pressure readings to a receiver inside the vehicle. These readings are displayed when using the GAGES button on the DIC. If you are unable to display your tire pressures while the vehicle speed is greater than 15 mph (24 km/h), you may need to have your sensor ID codes learned by the vehicle. See your dealer.
