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. When the vehicle is station-
ary, moving objects can be detected and
marked.
To ensure that you can use the function, it must
be switched on in the multimedia system (see
the separate operating instructions).
360° camera (surround view)
General notes
The 360° camera is a system consisting of four
cameras.
The system processes images from the follow-
ing cameras:
RRear view camera
RFront camera
RTwo side cameras in the exterior mirrors
The cameras capture the immediate surround-
ings of the vehicle. The 360° camera assists
you, for instance when parking or at exits with
reduced visibility.
You can show images from the 360° camera in
full-screen mode or in six different split-screen
views on the multimedia system. 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:
Rtop view and picture from the rear view cam-
era (130° viewing angle)
Rtop view and image from the front camera
(130° viewing angle without displaying the
maximum steering wheel angle)
Rtop view and enlarged rear view
Rtop view and enlarged front view
Rtop view and images from the rear-facing side
cameras (rear wheel view)
Rtop view and images from the forward-facing
side cameras (front wheel view)
When the function is active and you shift the
transmission from Dor Rto N, the guide lines
are hidden in the multimedia system. When you change between transmission posi-
tions
Dand R, you see the previously selected
front or rear view.
Distances measured by PARKTRONIC will also
be optically displayed:
Rin split screen view as red or yellow brackets around the vehicle icon in the top view, or
Rat the bottom right as red or yellow brackets
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.
Ryellow brackets with thin lines: PARKTRONIC
is active
Ryellow brackets with normal lines: an object is present in close range of the vehicle
Rred line: an object is present in the immediate
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 incor-
rectly or not at all. The 360°camera is not a
substitute for attentive driving.
You are always responsible for safe maneuver-
ing and parking. When maneuvering or parking,
make sure that there are no persons, animals or
objects in the area in which you are maneuver-
ing.
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 oth-
ers.
The 360° camera will not function or will func-
tion in a limited manner:
Rif the doors are open
Rif the exterior mirrors are folded in
Rif the trunk lid is open
Rin heavy rain, snow or fog
Rat night or in very dark places
Rif the cameras are exposed to very bright light
Rif the area is lit by fluorescent bulbs or LED
lighting (the display may flicker)
Rif the camera lenses fog up, e.g. when driving
into a heated garage in winter, causing a rapid
change in temperature

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 increas-
ing 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:
Rif the length of the journey is less than approx-
imately 30 minutes
Rif the road condition is poor, e.g. if the surface
is uneven or if there are potholes
Rif there is a strong side wind
Rif you have adopted a sporty driving style with
high cornering speeds or high rates of accel-
eration
Rif you are predominantly driving slower than
37 mph (60 km/ h)or faster than 125 mph
(200 km/h)
Rif you are driving with the active Steer Assist
of DISTRONIC PLUS
Rif the time has been set incorrectly
Rin active driving situations, such as when you
change lanes or change your speed The ATTENTION ASSIST tiredness assessment
is deleted and restarted when continuing the
journey, if:
Ryou switch off the engine
Ryou take off your seat belt and open the driv-
er's door, e.g. for a change of drivers or to
take a break
Displaying the attention level
You can have current status information dis-
played in the assistance menu (Ypage 269) of
the on-board computer.
XSelect the Assistance display for ATTENTION
ASSIST using the on-board computer
(
Ypage 268).
The following information is displayed:
Rlength of the journey since the last break.
Rthe attention level determined by ATTENTION ASSIST (Attention Level), displayed in a
bar display in five levels from high to low
Rif ATTENTION ASSIST is unable to calculate
the attention level and cannot issue a warn-
ing, the 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).

Warning display
:Warning display
Active Blind Spot Assist is not operational at
speeds below approximately 20 mph (30 km/h).
Vehicles in the monitoring range are then not
indicated.
If a vehicle is detected within the blind spot
monitoring range at speeds above 20 mph
(30 km/h), warning lamp :on the correspond-
ing side lights up red. This warning is always
emitted when a vehicle enters the blind spot
monitoring range from behind or from the side.
When you overtake a vehicle, the warning only
occurs if the difference in speed is less than
7 mph (12 km/h).
If you select the reverse gear, Active Blind Spot
Assist is not operational.
The brightness of the warning lamps is auto-
matically adapted to the brightness of the sur-
roundings.
When Active Blind Spot Assist is activated, gray
radar waves propagating backwards appear
next to the vehicle in the assistance display in
the multifunction display. Above a speed of
20 mph (30 km/h), the color of the radar waves
in the assistance display changes to green ;.
Active Blind Spot Assist is then ready for use.
Visual and acoustic collision warning
If you switch on the turn signals to change lanes and a vehicle is detected in the side monitoring
range, you receive a visual and acoustic collision warning. You will then hear a double warning tone and red warning lamp
:flashes. If the turn
signal remains on, detected vehicles are indica-
ted by the flashing of red warning lamp :.
There are no further warning tones.
Course-correcting brake application
If Active Blind Spot Assist detects a risk of a lat-
eral collision in the monitoring range, a course-
correcting brake application is carried out. This
is meant to assist you in avoiding a collision.
GWARNING
A course-correcting brake application cannot always prevent a collision. There is a risk of an
accident.
Always steer, brake or accelerate yourself,
especially if Active Blind Spot Assist warns
you or makes a course-correcting brake appli-
cation. Always maintain a safe distance at the
sides.
If a course-correcting brake application occurs,
red warning lamp :flashes in the exterior mir-
ror and a dual warning tone sounds. In addition,
display ;underlining the danger of a side col-
lision appears in the multifunction display.
In very rare cases, the system may make an
inappropriate brake application. A course-cor-
recting brake application may be interrupted at
any time by countersteering slightly or acceler-
ating.
The course-correcting brake application is avail-
able in the speed range between 20 mph
(30 km/h) and 120 mph (200 km/h).
236Driving systems
Driving and parking
Rthe radar sensors in the front or rear bumpers
or the radiator trim are dirty, e.g. obscured by
snow
Rthere are no, several or unclear lane markings
for a lane, e.g. in areas with road construction
work
Rthe lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow
Rthe distance to the vehicle in front is too small
and the lane markings thus cannot be detec-
ted
Rthe lane markings change quickly, e.g. lanes
branch off, cross one another or merge
Rthe road is narrow and winding
Rthere are strong shadows cast on the road
If no vehicle is detected in the adjacent lane and
broken lane markings are detected, no lane-cor-
recting brake application is made.
Warning vibration in the steering wheel
A warning may be given if a front wheel passes
over a lane marking. It will warn you by means of
intermittent vibration in the steering wheel for
up to 1.5 second s.
In orde r that you are warned only when neces-
sary and in good time if you cross the lane mark-
ing, the system recognizes certain conditions
and warns you accordingly.
The warning vibration occurs earlier if:
Ryou approach the outer lane marking on a
bend.
Rthe road has very wide lanes, e.g. a highway.
Rthe system recognizes solid lane markings.
The warning vibration occurs later if:
Rthe road has narrow lanes
Ryou cut the corner on a bend
Lane-correcting brake application
If you leave your lane, under certain circumstan-
ces the vehicle will brake briefly on one side.
This is meant to assist you in bringing the vehicle
back to the original lane.
GWARNING
A lane-correcting brake application cannot
always bring the vehicle back into the original lane. There is a risk of an accident.
Always steer, brake or accelerate yourself,
especially if Active Lane Keeping Assist warns
you or makes a lane-correcting brake appli-
cation.
GWARNING
Active Lane Keeping Assist does not detect
traffic conditions or road users. In very rare
cases, the system may make an inappropriate brake application, e.g. after intentionally driv-
ing over a solid lane marking. There is a risk of
an accident.
An inappropriate brake application may be
interrupted at any time if you steer slightly in
the opposite direction. Always make sure that
there is sufficient distance on the side for
other traffic or obstacles.
If a lane-correcting brake application occurs,
display :appears in the multifunction display.
The brake application also slightly reduces vehi-
cle speed.
A lane-correcting brake application can be made
after driving over a lane marking recognized as
being solid or broken. Before this, a warning
must be given by means of intermittent vibration
in the steering wheel. In addition, a lane with
lane markings on both sides must be recog-
nized.
In the case of a broken lane marking being
detected, a lane-correcting brake application
can only be made if a vehicle has been detected
in the adjacent lane. The following vehicles can
have an influence on brake application: oncom-
ing traffic, vehicles that are overtaking and vehi-
cles that are driving parallel to your vehicle.
iA further lane-correcting brake application
can only occur after your vehicle has returned
to the original lane.
