A vehicle includes a display device, a radar sensor having a detection region perpendicular to a vehicle longitudinal axis, a radar analyzer connected to the radar sensor, and a camera having a switchable field of view for covering an angular range behind the vehicle direction between a narrower angular range and a wider angular range. The display device is configured to display an image from the camera, at the narrower range, responsive to a sensor sensing vehicle movement in a direction included in a field of view of the camera, and the display device is configured to display an image from the camera at the wider range, responsive to the radar sensor detecting an object moving towards the vehicle. The vehicle may also be configured to automatically stop responsive to certain characteristics of objects detected by the radar sensor.
