A system for calculating the distance to empty available from the remaining fuel in a motor vehicle, wherein an average value of the distance traveled per unit of fuel consumed is multiplied by the quantity of fuel remaining, thereby producing an intermediate distance-to-empty value. Responsive to a first type signal being in a first state, a displayed value of DTE is allowed only to decrement. When the first type signal is in a second state, the displayed value of DTE is allowed to both increment and decrement. When the first type signal is in the first state, the updating of the calculation of the DTE value is recalculated as a function of the distance traveled by the vehicle and as a function of the fuel consumed by the vehicle. If the first type signal is in a second state, then the recalculation is controlled as a function of time.
