Federal law requires that the
odometer in any replacement
speedometer/odometer must r egister the same mileage as that registered on
the removed speedometer/odometer. Service replacement
speedometer/odometers and odometer modul es with the mileage preset to
actual vehicle mileage are available through the dealer. In nearly all cases, the
mileage continues to accumu late in the odometer memory even if the odometer
does not display mileage. Th is mileage can usually be verified by the dealer.
Contact the dealer for instructi ons to receive a replacement
speedometer/odometer with pres et mileage. If the actual vehicle mileage cannot
be verified, the dealer will supply a spe edometer/odometer with a display set to
zero miles. In addition, an odometer mileage sticker is supplied with the
replacement odometer. The sticker must display the estimated vehicle mileage
and is to be affixed to the driver's door.
