Arrangement for controlling the movement of a rearward-side air guiding system on motor vehicles, the rearward-side air guiding system having a rear spoiler provided on a rearward-side hood and a rear wing connected therewith, and the rear wing being movable by means of the arrangement from a retracted inoperative position into an extended operative position and vice versa. The arrangement for controlling the movement of the rear wing includes at least two telescopic tilt-out devices and one connection respectively between a driving device and the telescopic tilt-out device. The driving device contains a motor and at least one hydraulic cylinder, so that, when the motor ( ) is triggered, a pressure is built up in the at least one hydraulic cylinder ( &prime;) which can be transmitted to the telescopic tilt-out devices ( &prime;) and has the effect that the rear wing ( ) is moved against a spring force into its operative position.
