A method and apparatus for controlling a headlight system of a motor vehicle is disclosed. The headlight system can be actuated in at least two control modes, each having an associated, predetermined maximum main beam width. First, a current driving situation of the motor vehicle is captured on the basis of at least one operating, parameter of the motor vehicle. A current control mode is ascertained based on which control mode from at least two control modes matches a control mode assigned to the captured driving situation on the basis of the captured current driving situation and at least one-time or temporal parameter. The controller is shifted into the assigned control mode when the current control mode does not match the assigned control mode, wherein a maximum main beam width is set for the current driving situation.
