GM Service Manual Online
For 1990-2009 cars only

The speedometer shows the vehicle speed in both miles per hour (mph) and kilometers per hour (km/h).

The odometer shows how far the vehicle has been driven, in either miles (used in the United States) or kilometers (used in Canada).

This vehicle has a tamper resistant odometer. The digital odometer will read 999,999 if it is turned back.

If the vehicle needs a new odometer installed, it must be set to the mileage total of the old odometer. If that is not possible, then it must be set at zero and a label must be put on the driver door to show the old mileage reading when the new odometer was installed.
