Detection range
The detection capacity of the system and the
automatic braking capacity are limited.
Two-wheeled vehicles for instance might not
be detected.
WARNING
The system does not relieve from the
personal responsibility to correctly assess the
traffic situation. Based on the limits of the sys‐
tem, it cannot independently react to all traffic
situations. There is risk of an accident. Adjust
the driving style to the traffic conditions. Watch
traffic closely and actively interfere in the re‐
spective situations.◀
Deceleration
The system also does not decelerate in the fol‐
lowing situations:
▷In case of pedestrians, cyclists or similar
slow road users.▷For red traffic lights.▷For cross traffic.▷For oncoming traffic.▷Unlit vehicles or vehicles with nonworking
lighting at night.Swerving vehicles
A vehicle driving in front of you is not detected
until it is completely within the same lane as
your vehicle.
If a vehicle driving ahead of you suddenly
swerves into your lane, the system may not be
able to automatically restore the selected dis‐
tance. This also applies to major speed differ‐
ences to vehicles driving ahead of you, e.g.,
when rapidly approaching a truck. When a ve‐
hicle driving ahead of you is reliably detected,
the system requests that the driver intervene
by braking and carrying out evasive maneu‐
vers, if needed.

Cornering
If the desired speed is too high for a curve, the
speed is reduced slightly, although curves can‐
not be anticipated in advance. Therefore, drive
into a curve at an appropriate speed.
In tight curves the system offers only restricted
detection where a vehicle ahead of you might
be detected late or not at all.
When you approach a curve the system may
briefly report vehicles in the next lane due to
the bend of the curve. If the system deceler‐
ates you may compensate it by briefly acceler‐
ating. After releasing the gas pedal the system
is reactivated and controls speed independ‐
ently.
Driving away
In some situations, the vehicle cannot drive off
automatically; for example:
▷On steep inclines.▷From behind bumps in the road.
In these cases, press on the accelerator pedal.
Weather
In the event of unfavorable weather and light conditions, e. g. if there is rain, snowfall, slush,
fog or glare, this may result in poorer recogni‐
tion of vehicles as well as short-term interrup‐
tions for vehicles that are already detected. Drive attentively, and react to the current trafficsituation. If necessary, intervene actively, e.g.
by braking, steering or evading.
Malfunction
A Check Control message is displayed if the
system fails or was automatically deactivated.
The system may not be fully functional in the
following situations:▷When an object was not correctly de‐
tected.▷In heavy fog, rain, sprayed water or snow‐
fall.▷In tight curves.▷If the field of view of the camera or the front
windshield are dirty or covered.▷When driving toward bright lights.▷Up to 20 seconds after the start of the en‐
gine, via the Start/Stop button.▷During calibration of the camera immedi‐
ately after vehicle delivery.
Cruise control
The concept The system maintains a preset speed via the
buttons on the steering wheel. The system
brakes on downhill gradients if engine braking
is insufficient.
General information
Depending on the driving settings, the features
of the cruise control can change in certain
areas.

System limits
Limits of ultrasonic measurement
Ultrasonic measuring might not function under
the following circumstances:▷For small children and animals.▷For persons with certain clothing, e.g.
coats.▷With external interference of the ultra‐
sound, e.g. from passing vehicles or loud
machines.▷When sensors are dirty, iced over, dam‐
aged or out of position.▷Under certain weather conditions such as
high relative humidity, rain, snowfall, ex‐
treme 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 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
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, e.g., in underground ga‐
rages.▷In automatic car washes.▷Through heavy pollution.▷Due to other ultrasound sources, e.g.,
sweeping machines, high pressure steam
cleaners or neon lights.
The malfunction is signaled by a continu‐
ous tone alternating between the front and
rear speakers. As soon as the malfunction
due to other ultrasound sources is no lon‐
ger present, the system is again fully func‐
tional.
