With rear luggage rack or when the
trailer power socket is in use

Limits of ultrasonic measurement
The detection of objects with ultrasonic
measurements can run into physical limits,
for instance under the following conditions:
– For small children and animals.
– For persons with certain clothing, for in-
stance coats.
– With external interference of the ultra-
sound, for instance from passing vehi-
cles or loud machines.
– When sensors are dirty, iced over, dam-
aged or out of position.
– If cargo protrudes.
– Under certain weather conditions such
as high relative humidity, wet condi-
tions, snowfall, extreme heat, or strong
wind.
– With tow bars and trailer couplings 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 struc-
ture such as fences.
– For objects with porous surfaces.
– Low objects already displayed, for in-
stance curbs, can move into the blind
area of the sensors before or after a con-
tinuous tone sounds.
False warnings
The system 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
with 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, for instance in under-
ground garages.
– In automatic vehicle washes.
– Due to heavy exhaust.
– Due to other ultrasound sources, for in-
stance sweeping machines, high pres-
sure steam cleaners or neon lights.
The malfunction is signaled by a contin-
uous tone alternating between the front
and rear speakers. As soon as the mal-
function due to other ultrasound sources
is no longer present, the system is again
fully functional.
