13、 R56.Park distance controlThe park distance control (PDC) is a distance warning system that provides both visual and audible information on the distance to the nearest obstacle when parking and driving out of spaces.The distance to the nearest obstacle is measured by means of four sensors fitted in
14、the rear bumper.Depending on the equipment configuration, the signal tones are produced and output by means of the existing audio system or by means of a separate piezospeaker specifically installed for the PDC.The frequency of the signal increases as the distance to the obstacle decreases. A perman
15、ent tone signal is output in close proximity to obstacles.When the vehicle is equipped with the corresponding option, the graphic distance signalling is shown on the central information display.PDC is optionally available in the R56 as variant SA507 PDC, rear.The following changes/new features have
