An electronic monitor displays a tire position for each of a plurality of tires on a motor vehicle and provides a warning if a pressure reading received from any of the tires is outside a selected range of the baseline tire pressure value established for that tire position. The tire position and baseline tire pressure value are established by using navigation keys and a pair of control keys on the monitor. In an earlier method of establishing one or more baseline tire pressure values, the baseline value was entered on a tire-by-tire basis. The present improvement enables the operator to enter a baseline value globally for all tire positions. First a tire selection mode is entered, and a tire position is selected. Next, a baseline tire pressure selection mode is entered and a baseline tire pressure value is selected. The baseline tire pressure value is then assigned and saved to all of the tire positions by simultaneously engaging the pair of control keys.
