A system for providing contactless movement of a vehicle door relative to a vehicle body including an electric-motor movement device for moving the vehicle door, a radar sensor system for detecting, in the region of the vehicle door, a gesture to be performed by a user, and a control device for controlling the movement device according to a detection by the radar sensor system. The radar sensor system is configured to detect, in a first operating mode, a movement in a detection region in an environment of the vehicle door and to detect, in a second operating mode, a gesture for moving the vehicle door, the radar sensor system being configured to switch to the second operating mode when a movement is detected in the first operating mode.
