• With the ignition off, press and hold the CAL/TRIP button. Turn the ignition on, then release the CAL/TRIP button.
• The odometer/trip display will indicate CAL to verify that calibration mode has been accessed. The pointer will move to 50% scale.
• Drive the vehicle EXACTLY one (1) measured mile then stop.
• Press the CAL/TRIP button again to complete the calibration.
• If the number of pulses is between 4,000 to 200,000 the odometer/trip display will indicate the actual pulses counted by the speedometer for five (5) seconds. This indicates a successful calibration. The speedometer will return to normal operation automatically.

If the number of pulses is below 4,000 at the end of one mile, the odometer/trip display will show zeros for five (5) seconds after the button is pressed. The calibration will not be updated, and the original calibration will be maintained. If this occurs you most likely have a problem with your sender and/or wiring. Correct the problem and recalibrate the speedometer.
