Systems and methods for operating a driver assistance system of a motor vehicle are provided, wherein the motor vehicle has at least one radar sensor which captures the environment of the motor vehicle. The radar sensor data is evaluated to form an environmental model describing the environment of the motor vehicle. If at least one query criterion is satisfied, an environmental map derived from the environmental model, and illustrating a top view of regions which can and cannot be travelled on is displayed on the display device. During an interaction between the driver and the displayed environmental map, trajectory data describing a desired trajectory of the driver is determined, and the motor vehicle is at least partially automatically guided along a real trajectory derived from the trajectory data.
