Active Parking Assist
General notes
Active Parking Assist is an electronic parking
aid with ultrasound. It measures the road on
both sides of the vehicle. A parking symbol
indicates a suitable parking space. Active
steering intervention and brake application
can assist you during parking and when exit-
ing a parking space. You may also use
PARKTRONIC (
Ypage 199).
Important safety notes
Active Parking Assist is merely an aid. It is not
a replacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering, parking
and exiting a parking space. Make sure that
no persons, animals or objects are in the
maneuvering range.
When PARKTRONIC is switched off, Active
Parking Assist is also unavailable.
GWARNING
While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
result in a collision with another road user.
There is a risk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Active Park- ing Assist parking procedure.
!If unavoidable, you should drive over
obstacles such as curbs slowly and not at a
sharp angle. Otherwise, you may damage
the wheels or tires.
Active Parking Assist may possibly indicate
parking spaces which are not suitable for
parking, for example:
Rwhere parking or stopping is prohibited
Rin front of driveways or entrances and exits
Ron unsuitable surfaces

tion.
XDrive forwards and back up as prompted by
the PARKTRONIC warning displays, several
times if necessary.
Once you have exited the parking space com-
pletely, the steering wheel is moved to the
straight-ahead position. You hear a tone and
the Park Assist Finished
message
appears in the multifunction display. You will
then have to steer and merge into traffic on
your own. PARKTRONIC is still available. You
can take over the steering, before the vehicle
has exited the parking space completely. This
is useful, for example when you recognize
that it is already possible to pull out of the
parking space.

Rear view camera :is an optical parking and
maneuvering aid. It shows the area behind
your vehicle with guide lines in the COMAND
display.
The area behind the vehicle is displayed as a
mirror image, as in the rear view mirror.
iThe text of messages shown in the
COMAND display depends on the language
setting. The following are examples of rear
view camera messages in the COMAND
display.
Important safety notes
The rear view camera is only an aid. It is not a
replacement for your attention to your imme-
diate surroundings. You are always responsi-
ble for safe maneuvering and parking. When
maneuvering or parking, make sure that there
are no persons, animals or objects in the area in which you are maneuvering. Under the following circumstances, the rear
view camera will not function, or will function
in a limited manner:
Rif the trunk lid is open
Rin heavy rain, snow or fog
Rat night or in very dark places
Rif the camera is exposed to very bright light
Rif the area is lit by fluorescent bulbs or LED
lighting (the display may flicker)

Night View Assist Plus
General notes
In addition to the illumination provided by the
normal headlamps, Night View Assist Plus
uses infrared light to illuminate the road.
Night View Assist Plus camera ;picks up the
infrared light and displays a monochrome
image in the multifunction display. The image
shown in the display corresponds to a road lit
up by high-beam headlamps. This enables you to see the road's course and any obstacles in
good time. When pedestrian recognition is
active, pedestrians recognized by the system are visually highlighted in color in the Night
View Assist Plus display with small frame cor-
ners.
In addition, an infrared camera is integrated
into the radiator trim :. The camera helps
detect pedestrians and animals. Observe the
notes on cleaning the infrared camera
(
Ypage 337).
iInfrared light is not visible to the human
eye and therefore does not glare. Night
View Assist Plus can therefore remain
switched on even if there is oncoming traf-
fic.
Important safety notes
Night View Assist Plus is only an aid and is not
a substitute for attentive driving. Do not rely
on the Night View Assist Plus display. You are
responsible for the distance to the vehicle in
front, for vehicle speed and for braking in
good time. Drive carefully and always adapt your driving style to suit the prevailing road
and traffic conditions.
The system may be impaired or may not func-
tion if:
Rif there is poor visibility, e.g. due to snow,
rain, fog or spray
Rif the windshield is dirty, fogged up or cov-
ered, for instance by a sticker, in the vicinity
of the camera
Rif the thermal imaging camera in the radia-
tor grill is dirty, fogged up or covered
Ron bends, hilltops or downhill gradients
Rat high outside temperatures
Night View Assist Plus cannot display objects
directly in front of or beside the vehicle.
It may be the case that other objects are
marked or highlighted as well as pedestrians
and animals.
Pedestrian and animal recognition
General notes
Pedestrian or animal recognition may be
impaired or inoperative if:
Rpedestrians or animals are partially or
entirely obscured by other objects, e.g.
parked vehicles
Rthe silhouette of the pedestrian or of the
animal in the Night View Assist Plus display
is incomplete or interrupted, e.g. by pow-
erful light reflections
Rpedestrians or animals do not contrast with
the surroundings
Rthe camera system no longer recognizes
pedestrians as persons due to special
clothing or other objects
Rpedestrians are not in an upright position,
e.g. sitting, squatting or lying
Ranimals are not recognized by the system,
e.g. because of their size or shape
Pedestrian and animal recognition is deacti-
vated at temperatures above 90 ‡ (32 †).
The spotlight function and automatic delayed
switch-off are then no longer active.

actual distance to objects and pedestrians
cannot be gaged accurately by looking at a
screen.
Animal recognition
Animals can be recognized in the following
situations:
Rdarkness
Routside built-up areas
Rbelow an outside temperature of 90 ‡
(32 †) Night View Assist Plus can recognize larger
animals such as deer, cows or horses using
typical characteristics.
The system does not detect:
Rsmaller animals, e.g. dogs and cats
Ranimals whose silhouette is not clearly rec-
ognizable
When detected, animals are marked with
small color frame corners. In contrast to
pedestrian recognition, there is no separate
readiness symbol in the multifunction dis-
play.
