Audio 20 or COMAND display in yellow or red
respectively. 360° camera
General notes The 360° camera is a system consisting of
four cameras.
The system analyzes images from the follow- ing cameras:
R Rear view camera
R Front camera
R Two cameras in the exterior rear view mir-
rors
The cameras capture the immediate sur-
roundings of the vehicle. The system sup-
ports you, e.g. when parking or if vision is
restricted at an exit.
You can show pictures from the 360° camera in full-screen mode or in six different split-
screen views on the COMAND/Audio 20 dis-
play. A split-screen view also includes a top
view of the vehicle. This view is calculated
from the data supplied by the installed cam-
eras (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 images from the side mirror
cameras (rear wheel view)
R top view and images from the side mirror
cameras (front wheel view)
When the function is active and you shift the
transmission from Dor Rto N, the dynamic
guidelines are hidden.
When you change between transmission
positions Dand R, you see the previously
selected front or rear view. Distances measured by PARKTRONIC will
also be optically displayed:
R in split screen view as red or yellow brack-
ets around the vehicle icon in the top view, or
R at the bottom right as red or yellow brack-
ets around the vehicle symbol in full-screen mode
The line thickness and color of the brackets
show how far the vehicle is from an object. R yellow brackets with thin lines:
PARKTRONIC is active
R yellow brackets with normal lines: an
object is present in close range of the vehi-
cle
R red line: an object is present in the imme-
diate close range of the vehicle
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 maneu-
vering 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 surround-
ings 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/tailgate 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 Driving systems

R
if the area is lit by fluorescent bulbs or LED
lighting (the display may flicker)
R if there is a sudden change in temperature,
e.g. when driving into a heated garage in
winter
R if the camera lenses are dirty or covered
R if the vehicle components in which the
cameras are installed are damaged. In this
event, have the camera position and setting checked at a qualified specialist workshop.
Do not use the 360° camera in this case. You can otherwise injure others or cause damage
to objects or the vehicle.
Guide lines are always shown at road level.
On vehicles with height-adjustable chassis,
depending on technical conditions, leaving
the standard height can result in:
R inaccuracies in the guide lines
R inaccuracies in the display of generated
images (top view)

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 ATTEN-
TION ASSIST detects typical indicators of fati-
gue or increasing lapses in concentration on
the part of the driver, it suggests taking a
break. Important safety notes ATTENTION ASSIST is only an aid to the
driver. It might not always recognize fatigue
or increasing inattentiveness in time or fail to
recognize them at all. The system is not a
substitute for a well-rested and attentive
driver.
The functionality of ATTENTION ASSIST is
restricted and warnings may be delayed or
not occur at all:
R if the length of the journey is less than
approximately 30 minutes
R if the road condition is poor, e.g. if the sur-
face is uneven or if there are potholes
R if there is a strong side wind
R if you have adopted a sporty driving style
with high cornering speeds or high rates of
acceleration
R if you are predominantly driving at a speed
below 37 mph (60 km/h) or above 124 mph
(200 km/h)
R if you are driving with the DISTRONIC PLUS
Steering Assist activated
R if the time has been set incorrectly
R in active driving situations, such as when
you change lanes or change your speed
ATTENTION ASSIST is reset when you con-
tinue your journey and starts assessing your
tiredness again if:
R you switch off the engine
R you take off your seat belt and open the
driver's door, e.g. for a change of drivers or to take a break
Displaying the attention level Driving systems

You can have current status information dis-
played in the assistance menu (Y page 235)
of the on-board computer.
X Select the Assistance display for ATTEN-
TION ASSIST using the on-board computer
(Y page 235).
The following information is displayed:
R length of the journey since the last break.
R the attention level determined by ATTEN-
TION ASSIST, displayed in a bar display in
five levels from high to low.
R if ATTENTION ASSIST is unable to calculate
the attention level and cannot output a
warning, the System Suspended System Suspended message
appears. The bar display then changes the
display, e.g. if you are driving at a speed
below 37 mph (60 km/h) or above 124 mph
(200 km/h).
Activating ATTENTION ASSIST X
Activate ATTENTION ASSIST using the on-
board computer (Y page 236).
The system determines the attention level
of the driver depending on the setting
selected:
Standard selected: the sensitivity with
which the system determines the attention
level is set to normal.
Sensitive selected: the sensitivity is set
higher. The attention level detected by Atten- tion Assist is adapted accordingly and the
driver is warned earlier.
When ATTENTION ASSIST is deactivated, the À symbol and OFF appear in the multi-
function display in the assistance display
when the engine is running.
When ATTENTION ASSIST has been deactiva- ted, 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 concentra-
tion are detected, a warning appears in the
multifunction display: Attention Assist:
Attention Assist:
Take a Break! Take a Break!
In addition to the message shown in the mul-
tifunction display, you will then hear a warn-
ing tone.
X If necessary, take a break.
X Confirm the message by pressing the a
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, 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 lap-
ses in concentration.
Vehicles with COMAND: if a warning is
issued 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 func- tion can be activated and deactivated in
COMAND. Lane Tracking package
General notes The Lane Tracking package consists of Blind
Spot Assist (Y
page 214) and Lane Keeping
Assist (Y page 216).
Blind Spot Assist General notes
Blind Spot Assist uses a radar sensor system
to monitor the areas on both sides of your
vehicle. It supports you from a speed of
approximately 20 mph (30 km/h). A warning
display in the exterior mirrors draws your
attention to vehicles detected in the moni-
tored area. If you then switch on the corre-
sponding turn signal to change lanes, you will also receive an optical and audible collision 214
