Calibration

To calibrate your electronic speedometer:

1. With the power off, push and hold the calibration button (trip/reset button when equipped). While holding

the button, start the vehicle and continue to hold the button until the pointer sweeps to full scale and stays at

full scale. You may now release the button.

2. Drive to the beginning of a pre marked two mile stretch of road (ie: a toll road with accurate mile markers)

and come to a stop. It doesn’t matter how far away the stretch of road is. DO NOT shut off the engine. Push

the release button. The pointer will drop to half scale.

3. Drive the 2 mile distance. The pointer will remain at the half scale mark no matter what speed you choose to

drive the two mile stretch. If the speedometer has an LCD display odometer, it will be normal to see it count-

ing rapidly as it is receiving a speed signal. If you have to stop during the calibration that is ok. The speedom-

eter is simply counting pulses during this time.

4. At the end of the two mile distance, come to a complete stop, push and release the button. The pointer will

drop to 0 and the calibration will be stored.
