1. A method for warning a driver of a motor vehicle against cross traffic when leaving a parking space, the motor vehicle having, at least in a region of rear vehicle corners, long-range sensors for detecting possible cross traffic and lateral short-range sensors for detecting a nearby vehicle environment, the method comprising:

  • measuring a nearby lateral environment of the motor vehicle using the short-range sensors to generate a short range-detection when the motor vehicle is leaving the parking space;

    entering measurements of the nearby lateral environment into an environment map;

    detecting possible cross traffic using the long-range sensors; and

    generating a warning in response to at least one of the long-range sensors detecting cross traffic,using the environmental map to determine whether the long-range sensors have a clear view of the cross traffic, and generating an indication for the driver in response to one or both long-range sensor(s) not having the clear view of the cross traffic.
