▷ When towing a trailer.
▷ In angled parking spaces.
Functional limitations
The system may have limited functionality in the
following situations, for example:
▷ On uneven road surfaces, for example gravel
roads.
▷ On slippery surfaces.
▷ On steep upward or downward gradients.
▷ If leaves have collected or snow has drifted or
been piled up in the parking space.
▷ If the emergency wheel has been fitted.
▷ If there is a change in a measured parking
space.
▷ If there are ditches or sudden drops, for ex‐
ample a quayside.
Limits of ultrasound measurement
Certain conditions and objects may push ultra‐
sound measurement to its physical limits, includ‐
ing the following:
▷ Small children and animals.
▷ Persons wearing certain types of clothing, for
example a coat.
▷ External interference with the ultrasound, for
example by passing vehicles or loud ma‐
chines.
▷ Sensors which are dirty, iced up, damaged or
incorrectly adjusted.
▷ Certain weather conditions; for example, high
humidity, wet conditions, snowfall, cold, ex‐
treme heat or strong wind.
▷ Trailer drawbars and tow hitches of other ve‐
hicles.
▷ Thin or wedge-shaped objects.
▷ Moving objects.
▷ Higher protruding objects, for example pro‐
jecting walls.
▷ Objects with corners, edges and smooth sur‐
faces.
▷ Objects with fine surfaces or structures, for
example fences.
▷ Objects with porous surfaces.
▷ Small and low objects such as boxes.
▷ Obstacles and people at the edge of the lane.
▷ Soft obstacles or obstacles covered in foam.
▷ Plants or shrubs.
▷ Low objects already indicated, for example
kerbs, may enter the sensors' blind areas be‐
fore or after a continuous tone is given.
▷ The system does not take into account loads
projecting beyond the outline of the vehicle.
In some cases, parking spaces may be detected
that are not suitable or suitable parking spaces
may not be detected.
Malfunction
A Check Control message is shown.
Park Assistant has failed. Have the system
checked by a Service Partner of the manufac‐
turer or another qualified Service Partner or a
specialist workshop.
Crossing traffic warning
Principle
At blind exits or when leaving perpendicular park‐
ing spaces, the system detects other road users
approaching from the side earlier than is possible
from the driver's seat.
