Object detection
The rear view camera helps detect moving and
stationary objects. If an object (person, vehicle
or other obstacle) is detected, this object is
marked with abar. Objects located some dis-
tance from the vehicle awaya re marked with a
yellow bar. If the distance to the object is very
small, the bar is displayed in red.
Object detection only works in wide-angle view.
To ensure that you can use the function, it must
be switched on in the multimedia system (see
the separate operating instructions).
360° camera
General notes
The 360° camera is asystem 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 system supports you, for
example when parking or if vision is restricted at
an exit.
You can show images from the 360° camera in
full-screen mode or in six different split-screen
views on the multimedia system.
Asplit-screen
view also includes atop 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,t he guide lines
are hidden in the multimedia system.
When you change between transmission posi-
tions Dand R,you see the previouslys elected
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,
Driving systems185

make sure that there are no persons, animals or
objects in the area in which you are maneuver-
ing.
You are alwaysresponsible for safety ,and must
alwaysp ay attention to you rsurroundings when
parking and maneuvering. This applie stothe
area sbehind, in front of and beside the vehicle.
You could otherwise endange ryourself and oth-
ers.
The 360° camera wil lnot function or wil lfunc-
tion in alimited manner:
Rif the doors are open
Rif the exterior mirrors are foldedi n
Rif the trunk lid is open
Rin heavy rain, snow or fog
Rat night or in very dark places
Rif the camerasare exposed to very brigh tlight
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 aheated garage in winter, causing arapid
change in temperature
Rif the camera lenses are dirty or covered
Rif the vehiclec omponents in which the cam-
eras are installed are damaged. In this event,
have the camera position and setting checked
at aq ualified specialist workshop
Do not use the 360° camera in this case. You
can otherwise injure others or cause damage to
objects or the vehicle.
The guide lines in the multimedia system display
show the distances to you rvehicle. The distan-
ces only apply to road level.
The camera in the rear area is protected by
means of aflap .This flap opens when the 360°
camera is activated .Observe the notes on
cleaning (
Ypage 296) .For technical reasons,
the flap may remai nopen briefl yafter the 360°
camera has been deactivated.
The fiel dofvisiona nd other functions of the
camera system may be restricted due to addi-
tional accessories on the rear of the vehicle( e.g.
license plate holder, bicycle rack).
On vehicles with height-adjustable chassis,
depending on technica
l conditions, leaving the
standard height can resul tin:
Rinaccuracies in the guide lines
Rinaccuracies in the display of generated
images (top view)

Lane Keeping Assist
General notes
Lane Keeping Assist monitor sthe area in front of
your vehicle by means of multifunction cam-
era :which is attached behind the top of the
windshield. Active Lane Keeping Assist detects
lane markings on the road and can warn you
before you leave your lane unintentionally. This function is available in the range between
40 mph and 120 mph (60 km/h and 200 km/h).
Aw
arning may be given if afront wheel passes
over alane marking. It will warn you by means of
intermittent vibration in the steering wheel for
up to 1.5 seconds.
Important safety notes
GWARNING
Lane Keeping Assist may not always clearly
recognizel ane markings.
In this case, Lane Keeping Assist may:
Rgive an unnecessary warning
Rnot give awarning
There is arisk of an accident.
Always pay particular attention to the traffic
situation and stay in lane, in particular if
warned by Lane Keeping Assist.
GWARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There is
ar isk of an accident.
You should always steer, brake or accelerate
yourself, in particular if warned by Lane Keep-
ing Assist.
If you fail to adapt your driving style, Lane Keep-
ing Assist can neither reduce the risk of an acci-
dent nor override the laws of physics. Lane
Keeping Assist cannot take into account the
road, traffic and weather conditions. Lane Keep- ing Assist is merely an aid. You are responsible
for the distance to the vehicle in front,f or vehi-
cle speed, for braking in good time and for stay-
ing in your lane.
The Lane Keeping Assist does not keep the vehi-
cle in the lane.
The system may be impaired or may not function
if:
Rthere is poor visibility, e.g. due to insufficient
illumination of the road, or due to snow, rain,
fog or spray
Rthere is glare, e.g. from oncomingt raffic, the
