Parking assistance systems
The following parking assist systems provide assistance with parking and maneuvering:
PDC Park Distance Control
The concept
PDC support when parking. Slowly approaching an object behind or, with the appropriate PDC equipment, also in front of your vehicle is signaled by:
Signal tones.
Visual display.
General information
Measurements are made by ultrasound sensors in the bumpers.
The range, depending on the obstacle and environmental conditions, is approx. 6 ft/2 m .
An acoustic warning is first given:
By the front sensors and the two rear corner sensors at approx. 24 in/60 cm .
By the rear middle sensors at approx. 5 ft/1.50 m .
To ensure full operability:
Do not cover sensors, e.g., by stickers, bicycle racks and the like.
Keep the sensors clean and free of ice.
When using high-pressure washers, do not spray the sensors for long periods and maintain a distance of at least 12 in/30 cm .

Signal tones
When approaching an object, an intermittent tone is sounded that indicates the position of the object. For example, if an object is detected to the left rear of the vehicle, a signal tone sounds from the left rear speaker.
The shorter the distance to the object becomes, the shorter the intervals.
If the distance to a detected object is less than approx. 10 in/25 cm , a continuous tone is sounded.
With front PDC: if objects are located both in front of and behind the vehicle, an alternating continuous signal is sounded.
The signal tone is switched off:
When the vehicle moves away from an object by more than approx. 4 in/10 cm .
Volume
The volume of the PDC signal tone can be adjusted similar to the tone and volume settings of the radio.
The setting is stored for the remote control currently in use.
Visual warning
The approach of the vehicle to an object can be shown on the Control Display. Objects that are farther away are displayed on the Control Display before a signal tone sounds.
A display appears as soon as Park Distance Control (PDC) is activated.
The range of the sensors is represented in the colors red, green and yellow.
When the image of the rearview camera is displayed, the switch can be made to PDC:
"Rear view camera"
System limits
Limits of ultrasonic measurement
The detection of objects can reach the physical limits of ultrasonic measurement, e.g., in the following circumstances:
For small children and animals.
For persons with certain clothing, e.g. coats.
If there is an external disturbance of the ultrasound, e.g. from passing vehicles or loud machines.
When sensors are dirty, iced over, damaged or out of position.
Under certain weather conditions, such as high relative humidity, rain, snowfall extreme heat or strong wind.
With tow bars and trailer hitches of other vehicles.
With thin or wedge-shaped objects.
With moving objects.
With elevated, protruding objects such as ledges or cargo.
With objects with corners and sharp edges.
With objects with a fine surface structure, such as fences.
For objects with porous surfaces.
Low objects already displayed, e.g., curbs, can move into the blind area of the sensors before or after a continuous tone sounds.
False warnings
PDC may issue a warning under the following conditions even though there is no obstacle within the detection range:
In heavy rain.
When sensors are very dirty or covered in ice.
When sensors are covered in snow.
On rough road surfaces.
On uneven surfaces, such as speed bumps.
In large buildings with right angles and smooth walls, e.g., in underground garages.
In heavy exhaust.
Due to other ultrasound sources, e.g., sweeping machines, high pressure steam cleaners or neon lights.
The malfunction is signaled by a continuous tone alternating between the front and rear speakers. As soon as the malfunction due to other ultrasound sources is no longer present, the system is again fully functional.
Malfunction
A Check Control message is displayed.
The range of the sensors is shown as a shaded area on the Control Display.
PDC has failed. Have the system checked.
To ensure full operability:
Keep the sensors clean and free of ice.
Do not adhere any stickers to the sensors.
When using high-pressure washers, do not spray the sensors for long periods and maintain a distance of at least 12 in/30 cm .
