This innovative driver-assistance system uses four cameras whose live images are automatically combined into a single "overhead" view that's displayed on the in-dash screen during low-speed maneuvers. To help you better negotiate tight spaces, the system shows an area approximately 3 feet in all four directions around your GL-Class, with the image automatically adapted to the selected gear. Active parking guidelines on the screen help you back into a parking space, while a special rear view zoom mode helps you line up the optional trailer hitch of your GL-Class with your trailer. You can also select the images of each camera individually through the COMAND system controller.
