GM Service Manual Online
For 1990-2009 cars only

The speedometer lets you see your speed in either miles per hour (mph) or kilometers per hour (km/h). The odometer shows how far your vehicle has been driven, in either miles (used in the United States) or kilometers (used in Canada).

You may wonder what happens if a vehicle has to have a new odometer installed. The new one may read the correct mileage. This is because your vehicle's computer has stored the mileage in memory.

While the tap up/tap down feature is active, the odometer will change to show the gear range. See Automatic Transmission Operation for more information.

Trip Odometers

The trip odometer can record the number of miles or kilometers traveled for up to two trips.

The trip odometer is part of the Driver Information Center (DIC). To access the trip odometer, use one of the following procedures:

Using the Base audio system, do the following:

  1. Press the INFO (Information) button located to the right of the screen to access the DIC menu.
  2. Scroll through the menu using the up or down arrows on the INFO button until you reach Trip Odometer A or Trip Odometer B.
  3. The selected trip odometer (A or B) will be displayed at the top of the screen with the accumulated mileage.

  4. Repeat the steps to view the other trip odometer.

You can reset the selected trip odometer by pressing CLR (Clear) button located in the center of the INFO button to the right of the screen. The mileage for that trip odometer will return to zero. Each trip odometer must be reset individually.

Using the Navigation audio system, do the following:

  1. Press and hold the vehicle information button in the upper right corner of the screen for three seconds to access the Vehicle Information menu.
  2. Use the up and down arrows on the screen to bring TRIP A or TRIP B into view. Then press the button next to the trip you wish to be viewed.
  3. The selected trip odometer (A or B) will be displayed at the top of the screen with the accumulated mileage.

  4. Press the RETURN button to return to the previous page.
  5. Repeat the steps to view the other trip odometer.

You can reset the selected trip odometer by pressing RESET button on the Vehicle Information menu. The mileage for the selected trip odometer will return to zero. Each trip odometer must be reset individually.
