An actuation mechanism for a top and a top receptacle cover of a motor vehicle for moving from a driver's seat position, the top receptacle cover between a closed position and an open position and the top between a second operating position and a third operating position, comprising a pivotable actuating lever and a displacement device operatively associated therewith, wherein the actuating lever and displacement device are configured and so operatively connected so that, by pivoting the actuating lever in a first direction, the top receptacle cover is moved from a closed position into an open position by the displacement device cooperating therewith, a first coupling element operatively connected with the displacement device takes up a receiving position in which a second coupling element provided on the top engages the first coupling element when the top is in the second operating position, such that, by repeated pivoting of the actuating lever into a second, reverse direction, an engaged coupling moves the top receptacle cover and the top together downwardly into the closed position and the third operating position, respectively.
