Gauge Indication Systems: Odometer
WARNING: This page is about a different car, the 2002 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.
A million-mile tamper-resistant odometer is standard. New speedometers have a resettable odometer.
NOTE:
Some state laws require that the odometer in any new speedometer must register the same as on the removed odometer. New speedometers and odometer modules with the mileage preset are available through Ford electronic repair centers.
If the actual vehicle mileage cannot be determined, the repair centers are able to supply odometers set to "0" miles. An odometer mileage sticker is supplied with the new odometer. This sticker must display the estimated vehicle mileage and be affixed to the driver door jamb.
