Claim:
1. A remaining energy supply warning system comprising: a remaining energy supply meter determining a remaining energy supply amount of a vehicle energy supply; a position detector detecting a position of a vehicle; a warning provider (i) setting an area-specific warning amount level for each of at least two areas, the area-specific warning amount level being different for each of the at least two areas, and (ii) providing an area-specific warning for each of the at least two areas based on the area-specific warning amount level for each of the at least two areas when a current position of the vehicle corresponds to one of the at least two areas and the remaining energy supply amount of the vehicle energy supply is equal to the area-specific warning amount level; and a reminder provider (i) setting an area-specific reminder amount level to the at least two areas, and (ii) providing an area-specific reminder based on the reminder amount level that is higher than a lowest warning amount level when the current position of the vehicle corresponds to an area having the lowest warning amount level and the remaining energy supply amount of the vehicle energy supply is equal to the reminder amount level, wherein the area-specific reminder from the reminder provider has a lower notification intensity than the area-specific warning from the warning provider.
