GMC savana 2002 Manuale Utente

Your speedometer lets you see your speed in both 
miles per hour (mph) and kilometers per hour (km/h).
Your 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 your vehicle needs a
new odometer installed. Laws vary as to the procedure
that must be followed, so check with your state or
provincial vehicle registration office. But generally, if
the new odometer can be set to the mileage total of the
old odometer, then it must be. But if it can’t, then it’s 
set at zero, and a label must be put on the driver’s door
to show the old mileage reading when the new odometer
was installed.
