When the function is active and you shift the
transmission from Dor Rto N, the dynamic
guide lines are hidden.
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:
R as red or yellow brackets around the vehicle
symbol in top view in split-screen mode or
R at the bottom right as red or yellow brackets
around the vehicle symbol in full-screen mode
The line thickness and colour 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 vehicle
R red line: an object is present in the immediate
close range of the vehicle
i The camera in the rear area is protected
from raindrops and dust by means of a flap.
When the camera is activated, this flap opens.
The flap closes again when:
R you have finished the manoeuvring process
R you switch off the engine
R you open the luggage compartment
See the notes on cleaning (Y page 383).
For technical reasons, the flap may remain
open briefly after the camera has been deac-
tivated. 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.
The responsibility for safe manoeuvring and
parking remains with you. Make sure that there
are no persons, animals or objects in range
while manoeuvring and parking.
You are always responsible for safety, and must always pay attention to your surroundings when
parking and manoeuvring. 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 only in a limited manner:
R if the doors are open
R if the exterior mirrors are folded in
R if the 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
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 win-
ter
R if the camera lenses are dirty or covered
R if the vehicle components in which the cam-
eras are fitted are damaged. In this event,
have the camera position and setting checked
at a qualified specialist workshop.
Do not use the 360° camera under such cir-
cumstances. You could otherwise injure others
or damage objects when parking the vehicle.
Guide lines are always shown at road level. In
trailer mode, the guide lines are shown at the
level of the trailer coupling.
The field of vision and other functions of the
camera system may be restricted due to addi-
tional accessories on the rear of the vehicle (e.g.
licence plate holder, bicycle rack).
On vehicles with height-adjustable suspension,
due to the 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) Driving systems

Radar sensors
The radar sensors for Blind Spot Assist are inte-
grated into the rear bumper. Make sure that the
bumpers are free from dirt, ice or slush. The
sensors must not be covered, for example by
cycle racks or overhanging loads. Following a
severe impact or in the event of damage to the
bumpers, have the function of the radar sensors
checked at a qualified specialist workshop.
Blind Spot Assist may no longer work properly.
Monitoring range of the sensors
In particular, the detection of obstacles can be
impaired in the case of:
R dirt on the sensors or obscured sensors
R poor visibility, e.g. due to fog, heavy rain or
snow
R narrow vehicles, e.g. motorcycles or bicycles
Vehicles in the monitoring range are then not
indicated. Blind Spot Assist monitors the area up to 3.0 m
behind your vehicle and directly next to your
vehicle, as shown in the picture.
If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may be
indicated, especially if the vehicles are not driv-
ing in the middle of their lane. This may be the
case if there are vehicles at the edge of their lane nearest your vehicle.
On very wide lanes, vehicles in the lane next to
your vehicle may not be displayed if the vehicles
are too far away. Due to the nature of the system:
R warnings may be issued in error when driving
close to crash barriers or similar solid lane
borders
R warnings may be interrupted when driving
alongside long vehicles, for example lorries,
for a prolonged time
Warning display Blind Spot Assist is not active at speeds below
approximately 30 km/h. Vehicles in the moni-
toring range are then not indicated. :
Yellow indicator lamp/red warning lamp
If Blind Spot Assist is activated, indicator
lamp :in the exterior mirrors lights up yellow
up to a speed of 30 km/h. At speeds above
30 km/h, the indicator lamp goes out and Blind
Spot Assist is operational.
If a vehicle is detected within the monitoring
range of Blind Spot Assist at speeds above
30 km/h, warning lamp :on the correspond-
ing side lights up red. This warning always
occurs 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
12 km/h.
The yellow indicator lamp goes out if reverse
gear is engaged. Blind Spot Assist is then deac- tivated.
The brightness of the indicator/warning lamps
is adjusted automatically according to the ambi-
ent light.
Collision warning
If a vehicle is detected in the monitoring range of
Blind Spot Assist and you switch on the corre-
sponding turn signal, a double warning tone
sounds. Red warning lamp :flashes. If the turn
signal remains on, detected vehicles are indica- Driving systems

There are no further warning tones.
Activating Blind Spot Assist X Make sure that Blind Spot Assist is activated
in the on-board computer (Y page 291).
X Turn the key to position 2in the ignition lock.
Warning lamps :in the exterior mirrors light
up red for approximately 1.5 second s and
then turn yellow.
Towing a trailer
If you couple up a trailer, make sure that you
have correctly established the electrical con-
nection. This can be accomplished by checking
the trailer lighting. Blind Spot Assist is then
deactivated. The indicator lamp lights up yellow
in the exterior mirrors and the Blind Spot Blind Spot

i You can deactivate the indicator lamps in
the exterior mirrors.
To do so, you will need to deactivate Blind
Spot Assist if:
R the key is in position 2in the ignition lock
R the engine is not running
Lane Keeping Assist General notes
:
Lane Keeping Assist camera
Lane Keeping Assist monitors the area in front of
your vehicle by means of camera :at the top of
the windscreen. Lane Keeping Assist detects
lane markings on the road and can warn you
before you leave your lane unintentionally.
This function is available in a speed range
between 60 km/h and 200 km/h. A warning may be given if a front wheel passes
over a lane marking. It will warn you by means of
intermittent vibration through the steering
wheel for up to 1.5 second s.
Im portant safety notes G
WARNING
Lane Keeping Assist cannot always clearly
identify lane markings.
In these cases, Lane Keeping Assist may:
R give an unnecessary warning
R not give a warning
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep in lane, especially if Lane
Keeping Assist alerts you. G
WARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There is a risk of an accident.
Always steer, apply the brakes or accelerate
the vehicle yourself, especially if Lane Keep-
ing Assist alerts you.
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 road,
weather or traffic conditions. Lane Keeping
Assist is only an aid. You are responsible for the distance to the vehicle in front, for vehicle
speed, for braking in good time and for staying in
lane.
Lane Keeping Assist does not keep your vehicle
in its lane.
The system may be impaired or may not function if:
R there is poor visibility, e.g. due to insufficient
illumination of the road, or due to snow, rain,fog or spray
R there is glare, e.g. from oncoming traffic, the
sun or reflection from other vehicles (e.g. if
the road surface is wet)
R the windscreen is dirty, misted up, damaged
or covered, for instance by a sticker, in the
vicinity of the camera
R no or several, unclear lane markings are pres-
ent for one lane, e.g. in a construction area 246
