GM Service Manual Online
For 1990-2009 cars only

The speedometer lets you see your speed in both miles per hour (mph) and kilometers per hour (km/h).

Your vehicle's odometer works together with the driver information center. You can set a Trip A and Trip B odometer. See "Trip Information" under DIC Operation and Displays .

The odometer mileage can be checked without the vehicle running. Simply press the trip stem on the instrument panel cluster.

If your vehicle ever needs a new odometer installed, the new one will be set to the correct mileage total of the old odometer.
