GM Service Manual Online
For 1990-2009 cars only

The Driver Information Center (DIC) has different modes which can be accessed by pressing the reset stem on the instrument panel cluster. These modes are explained in the following section. To scroll through the available functions, press and release the reset stem.

Odometer

Press and release the reset stem until the odometer appears on the DIC. The odometer shows the total distance the vehicle has been driven in either miles for the United States or kilometers for Canada.

Trip Odometer

Press and release the reset stem until TRIP A or TRIP B appears on the DIC. The trip odometer shows the current distance traveled since the last reset of the trip odometer in either miles for the United States or kilometers for Canada.

To reset the trip odometer, press and hold the reset stem until the display returns to zero.

The DIC has different displays which can be accessed by pressing the reset stem located on the instrument panel cluster. These displays are explained in the following section. To scroll through the available functions, press and release the reset stem.

ODOMETER

Press and release the reset stem until ODOMETER displays. This display shows the distance the vehicle has been driven in either miles (mi) or kilometers (km).

TRIP

Press and release the reset stem until TRIP displays. This display shows the current distance traveled in either miles (mi) or kilometers (km) since the last reset for the trip odometer.

To reset the trip odometer to zero, press and hold the reset stem while the trip odometer is displayed.

RANGE

Press and release the reset stem until RANGE is displayed. The RANGE display will only be available when the vehicle is not in P (Park).

This display shows the approximate number of remaining miles (mi) or kilometers (km) the vehicle can be driven without refueling.

The fuel range estimate is based on an average of the vehicle's fuel economy over recent driving history and the amount of fuel remaining in the fuel tank. This estimate will change if driving conditions change. For example, if driving in traffic and making frequent stops, this display may read one number, but if the vehicle is driven on a freeway, the number may change even though the same amount of fuel is in the fuel tank. This is because different driving conditions produce different fuel economies. Generally, freeway driving produces better fuel economy than city driving.

If your vehicle is low on fuel, the FUEL LEVEL LOW message displays. See "FUEL LEVEL LOW" under DIC Warnings and Messages for more information.

INSTANT (Instantaneous) FUEL ECONOMY

Press and release the reset stem INSTANT FUEL ECONOMY displays.

This display shows the current fuel economy at a particular moment and will change frequently as driving conditions change. This display shows the instantaneous fuel economy in miles per gallon (mpg) or liters per 100 kilometers (L/100 km). This display cannot be reset.

AVERAGE FUEL ECONOMY

Press and release the reset stem AVERAGE FUEL ECONOMY displays.

This display shows the approximate average miles per gallon (mpg) or liters per 100 kilometers (L/100 km). This number is calculated based on the number of mpg (L/100 km) recorded since the last time this display was reset. To reset this display to zero, press and hold the reset stem.

OIL LIFE

Press and release the reset stem until OIL LIFE REMAINING displays. The OIL LIFE display will only be available when the vehicle is in P (Park). This display shows an estimate of the oil's remaining useful life. If OIL LIFE REMAINING 99% appears on the display, that means 99% of the current oil life remains. The engine oil life system will alert you to change the oil on a schedule consistent with your driving conditions.

When the remaining oil life is low, the CHANGE ENGINE OIL SOON message will appear on the display. See "CHANGE ENGINE OIL SOON" under DIC Warnings and Messages . Change the oil as soon as possible. See Engine Oil . In addition to the engine oil life system monitoring the oil life, additional maintenance is recommended in the Maintenance Schedule in this manual. See Scheduled Maintenance for more information.

Remember, reset the OIL LIFE 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 cannot be reset accurately until the next oil change. To reset the engine oil life system, see Engine Oil Life System .

UNITS

Press and release the reset stem until UNITS displays. This display selects the units of measurement. Once in this display, press the reset stem to select ENGLISH (default) or METRIC.

HOLD STEM TO SET LANGUAGE

Press and release the reset stem until HOLD STEM TO SET LANGUAGE displays. The HOLD STEM TO SET LANGUAGE display will only be available when the vehicle is in P (Park). This display selects the language in which the DIC messages will appear. Once in this display, press the reset stem to select ENGLISH (default), SPANISH, or FRENCH.

Tire Pressure

The pressure for each tire can be viewed in the DIC. The tire pressure will be shown in either pounds per square inch (psi) or kilopascals (kPa). Press and release the reset stem until the DIC displays FRONT TIRES LEFT ## PSI (kPa) RIGHT ## PSI (kPa). Press and release the reset stem again until the DIC displays REAR TIRES LEFT ## PSI (kPa) RIGHT ## PSI (kPa).

If a low or high tire pressure condition is detected by the system while driving, a message advising you to check the pressure in a specific tire will appear in the display. See Inflation - Tire Pressure and DIC Warnings and Messages for more information.

If the tire pressure display shows dashes instead of a value, there may be a problem with your vehicle. If this consistently occurs, see your dealer/retailer for service.

HOLD STEM TO RELEARN REMOTE KEY

This display matches Remote Keyless Entry (RKE) transmitters to your vehicle. To match a transmitter:

  1. Put the vehicle in P (Park).
  2. Press and release the reset stem until HOLD STEM TO RELEARN REMOTE KEY displays.
  3. Press and hold the reset stem until REMOTE KEY LEARNING ACTIVE is displayed.
  4. Press and hold the lock and unlock buttons on the first transmitter at the same time for about 15 seconds.
  5. A chime will sound indicating that the transmitter is matched and REMOTE KEY LEARNING COMPLETE will be displayed.

  6. To match additional transmitters at this time, repeat Step 4.
  7. Each vehicle can have a maximum of eight transmitters matched to it.

  8. To exit the programming mode, cycle the key to LOCK/OFF.

HOLD STEM TO SET ECO (Economy)

Press and release the reset stem until HOLD STEM TO SET ECO (Economy) displays. The HOLD STEM TO SET ECO display will only be available when the vehicle is in P (Park). This display turns the fuel economy light on or off. Once in this display, press the reset stem to select ON (default) or OFF. See Fuel Economy Light for more information.
