lever 34 the carriage 40 is restrained against rotation relative to the housing 36 and axially displaceable when being rotated by a user the actuating lever 34 is moved by means of the meshing threads 35 37 and the pin running in the guideway 38 axially away from the vehicle body 4 upwards a tie rod which is mounted on the lower end of the carriage 40 is pulled upwards to thereby disable the parking mode arranged between the housing 36 and the carriage 40 is a spring element 41 which generates a recoiling force when the actuating lever 34 is released to thereby move the actuating lever 34 back into the starting position fig1 shows the area of the guideway 38 of the housing 36 on an enlarged scale in fig1 the pin 39 is in its initial position i e in the non actuated state in which the parking mode is activated upon unlocking by a user the pin 39 is moved by the rotation of the actuating lever 34 along the guideway 38 as indicated by the double arrow fig1 shows together with fig1 the end position after the pin 39 has reached the upper end of the guideway 38 at the upper end of the guideway 38 the latter has a projecting detent portion 42 behind which the pin 39 locks into place this engagement is perceived by the user who can then recognize that the actuating lever 34 is in the locked position when applying a force the user is able to guide the pin 39 over the detent portion 42 the pin 39 is guided along the guideway 38 under the action of the spring element 41 while the carriage 40 is lowered until reaching again the initial position.
