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
exiting a parking space. You may also use
PARKTRONIC (Y page 218).
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. G
WARNING
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
Parking 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:
R where parking or stopping is prohibited
R in front of driveways or entrances and exits
R on unsuitable surfaces Driving systems

Object detection
The rear view camera can detect moving and
stationary objects. If, for example, a
pedestrian or another vehicle is detected,
these objects are marked with bars. The
system is only able to detect and mark
stationary objects when your vehicle is
moving. By contrast, stationary objects will
always be detected and marked.
To ensure that you can use the function, it
must be switched on in COMAND (see the
separate operating instructions). 360° camera (surround view)
General notes The 360° camera is a system consisting of
four cameras.
The system analyzes images from the
following cameras:
R Rear view camera
R Front camera
R Two cameras in the exterior rear view
mirrors
The cameras capture the immediate
surroundings of the vehicle. The system
supports you, e.g. when parking or if vision is
restricted at an exit.
The 360° camera images can be shown in full
screen mode or in seven different split-screen
views on the COMAND display. A split-screen
view also includes a top view of the vehicle.
This view is calculated from the data supplied
by the installed cameras (virtual camera).
The six split-screen views are:
R top view and picture from the rear view
camera (130° viewing angle)
R top view and image from the front camera
(130° viewing angle without displaying the
maximum steering wheel angle)
R top view and enlarged rear view
R top view and enlarged front view R
top view and pictures from the rearward
facing mirror cameras (rear wheel view)
R top view and pictures from the forward
facing mirror cameras (front wheel view)
When the function is active and you shift the
transmission from position Dor Rto N, you
see the view which was active before the
360° view in the COMAND display. The
dynamic guidelines are hidden.
When you change between transmission
positions Dand R, you see the previously
selected front or rear view.
Important safety notes The 360°camera is only an aid and may show
a distorted view of obstacles, show them
incorrectly or not at all. The 360°camera is
not a substitute for attentive driving.
You are always responsible 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.
You are always responsible for safety, and
must always pay attention to your
surroundings when parking and
maneuvering. This applies to the areas
behind, in front of and beside the vehicle. You
could otherwise endanger yourself and
others.
The 360° camera will not function or will
function in a limited manner:
R
if the doors are open
R if the exterior mirrors are folded in
R if the trunk lid is open
R in heavy rain, snow or fog
R at night or in very dark places
R if the cameras are exposed to very bright
light
R if the area is lit by fluorescent light or LED
lighting (the display may flicker)
R if the camera lenses fog up, e.g. when
driving into a heated garage in winter,
causing a rapid change in temperature 230

If the vehicle is equipped with PARKTRONIC
and the function is active ( Ypage 220),
warning displays 0044in the COMAND display
are also active or light up accordingly. PARKTRONIC appears:
R
in split screen view as red or yellow
brackets around the vehicle icon in the top
view, or
R in the full screen view, on the right-hand
side at the bottom as red or yellow brackets
around the vehicle icon
i The full screen display can also be

Select this view when you are driving out of
an exit and the view of crossing traffic is
restricted, for example.
i To select split-screen view, select the
0038 symbol in the display then confirm
with the COMAND controller.
Exiting 360° camera display mode As soon as your vehicle exceeds a speed of
19 mph (30 km/h) with the function
activated, the function switches off. The view
which was active before the 360° camera
was displayed appears in the COMAND
display. You can also stop the 360° camera
display from split-screen view by selecting
the 0038 symbol in the display and then
confirming with the COMAND controller.
The 360° camera display is also ended if you
select transmission position P. ATTENTION ASSIST
General notes ATTENTION ASSIST helps you during long,
monotonous journeys, such as on highways.
It is active in the 37 mph (60 km/h) to
125 mph (200 km/h) range. If
ATTENTION ASSIST detects typical indicators
of fatigue or increasing lapses in
concentration on the part of the driver, it
suggests taking a break.234
Driving systemsDriving an
d parking
When ATTENTION ASSIST is deactivated, the
00AD symbol and OFF appear in the
multifunction display in the assistance
display when the engine is running.
When ATTENTION ASSIST has been
deactivated, it is automatically reactivated
after the engine has been stopped. The
sensitivity selected corresponds to the last
selection activated (standard/sensitive).
Warning in the multifunction display If fatigue or increasing lapses in
concentration are detected, a warning
appears in the multifunction display:
Attention Assist: Take a Break! Attention Assist: Take a Break!
In addition to the message shown in the
multifunction display, you will then hear a
warning tone.
X If necessary, take a break.
X Confirm the message by pressing the
0076 button on the steering wheel.
On long journeys, take regular breaks in good
time to allow yourself to rest properly. If you
do not take a break and ATTENTION ASSIST
continues to detect increasing lapses in
concentration, you will be warned again after
15 minutes at the earliest. This will only
happen if ATTENTION ASSIST still detects
typical indicators of fatigue or increasing
lapses in concentration.
If a warning is output in the multifunction
display, a service station search is performed
in COMAND. You can select a service station
and navigation to this service station will then
begin. This function can be activated and
deactivated in COMAND. 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 0044picks 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
corners.
i Infrared 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
traffic.
In addition, thermal imaging camera 0043is
integrated in the radiator grill. The camera
helps detect pedestrians and animals.
Observe the notes on cleaning the thermal
imaging camera (Y page 359).
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 adapt236
