Park Distance Control
Introduction
This chapter contains information on the followingsubjects:
⇒ Switching on and off
⇒ Display representation
⇒ Settings
⇒ Troubleshooting
The Park Distance Control system
assists the driver when manoeuvring
and parking.
Park Distance Control detects the distance from an obstacle by means of sensors in the front and
rear bumpers ⇒ Vehicle overviews. If there is an obstacle in the detection range of the sensors, the
system indicates this on the Infotainment system and by means of signal tones.
System limits
The sensors may not always be able to detect objects such as trailer drawbars, thin rails, fences,
posts, trees, very low or high obstacles and open or opening boot lids.
In some cases, dirt and ice on the sensors could be registered as an obstacle.
Switching on and off
Fig. 153 In the centre console: button for switching Park Distance Control on and off (depending on
equipmentyf.
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Switching on Park Distance Control
•Select reverse gear.
•OR: press the button or .
The intelligent technology used in the parking systems cannot overcome the laws of
physics, and functions only within the limits of the system. Never let the extra
convenience afforded by the parking systems tempt you into taking any risks when
driving. The parking systems cannot replace the full concentration of the driver.
•Always adapt your speed and driving style to suit visibility, weather, road and traffic
conditions.
•Unintentional vehicle movements can cause serious injury.
•Keep looking in the direction in which you are parking and at the relevant area
surrounding the vehicle.
•Do not allow the displays in the instrument cluster and the images shown in the
Infotainment system to distract you from the traffic.
•Always monitor the area around the vehicle as the parking systems will not always
detect infants, animals and objects.
•The parking systems have blind spots in which obstacles and people are not
registered.
•External sources of sound and certain surfaces on objects and clothing may influence
the sensors' signals. In certain circumstances, the systems will be unable to detect or
properly detect people and objects.
•Certain objects, for example narrow posts or railings, may be difficult or impossible to
see on the screen because of its low resolution or poor light conditions.
•When approaching objects at high speeds, the parking systems' signals and displays
may not respond quickly enough to emit a warning.
