"This electronic speedometer displays speed and includes an odometer, trip meter, high speed recall, 0 - 60 time, and quarter-mile elapsed time. It can be calibrated with the push-button to adjust the speedometer for different tire sizes, wheel sizes, and gear ratios. The single push-button is used by a quick tap to toggle between odometer and trip meter."
