Motor vehicles are usually equipped with a fuel gauge indicating the amount of fuel available in the tank. However, problems can arise in steep upward slopes when the fuel runs backwardly in the tank so that it cannot be supplied to the motor. This invention provides a warning system that indicates to the driver of the vehicle when there is a potential risk for engine breakdown due to a steep upward slope. This is achieved by using information from an angle sensor together with information from a conventional fuel gauge sensor such that when the angle sensor indicates a large tilt angle and the fuel gauge sensor simultaneously indicates a small amount of fuel in the tank, the driver is alerted of this fact, e.g. by the lightning of a warning light on the instrument panel.
