NOTE: Tire size, wear and incorrect inflation can affect speedometer reading and odometer measurement. Allowable variance between actual vehicle speed and indicated speed is about 1/2 MPH for every 10 MPH of vehicle speed.

If speedometer is not functioning properly, remove and inspect speedometer cable. If cable is functional with no signs of wear or damage, replace speedometer.
