A method for operating a vehicle, in which the method allows feedback about imminent risks. In this context, the vehicle moves on a predefined route at a current traveling velocity. A value characteristic of the vehicle movement along the predefined route is precalculated as a function of the current traveling velocity and the predefined route. A vehicle function is activated as a function of this value.
