ABSTRACT:
A customizable low fuel indicator system for a motor vehicle having an engine control unit storing the average fuel economy of the motor vehicle. A fuel tank sensor is in electronic communication with the engine control unit and is adapted to sense the amount of fuel remaining in a fuel tank of the motor vehicle. An indicator is in electronic communication with the engine control unit. An input device is in communication with the electronic control unit for selecting a threshold distance to empty. The engine control unit calculates a distance to empty value based on the average fuel economy and the amount of fuel sensed by the fuel tank sensor. The indicator is activated by the engine control unit when the distance to empty is less than the threshold distance to empty.
