General notes The 360° camera is a system that consists of
four cameras.
The system evaluates images from the following
cameras:
R Reversing camera
R Front camera
R Two cameras in the exterior mirrors
The cameras cover the immediate surroundings
of the vehicle. The system assists you, for
instance when parking or at exits with reduced
visibility.
You can show pictures from the 360° camera in
full-screen mode or in seven different split-
screen views on the multimedia system 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 cam-
era).
The seven split-screen views are: Driving systems

side cameras (front wheel view)
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
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 boot 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 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)
Activation conditions The 360° camera image can be displayed if:
R your vehicle is equipped with a 360° camera
R the key is in position 2in the ignition lock

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.
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,

The two radar sensors for Blind Spot Assist are
integrated into the sides of the rear bumper.
Make sure that the bumper is free of dirt, ice or slush in the vicinity of the sensors. The sensorsmust not be covered, for example by cycle racks
or overhanging loads. Following a severe impact or in the event of damage to the bumpers, havethe function of the sensors checked at a quali-
fied specialist workshop. Blind Spot Assist may
otherwise not work properly. Indicator and warning display :
Indicator lamp (yellow)
Warning lamp (red)
Blind Spot Assist is not active at speeds below
approximately 30 km/h. Vehicles in the moni-
toring range are then not indicated.
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 or warning lampsis adjusted automatically according to the ambi-
ent light.

Lane Keeping Assist General notes
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 within 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 seconds.
Important 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 functionif:
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 Driving systems
195Driving and parking Z

As a result, Active Blind Spot Assist may nei-
ther give warnings nor intervene in such sit-
uations. There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and maintain a safe distance at the sideof the vehicle.
Radar sensors The Active Blind Spot Assist radar sensors are
integrated into the front and rear bumpers and
behind a cover in the radiator trim. Make sure
that the bumpers and the cover in the radiator
trim are free of dirt, ice or slush. The rear sen-
sors must not be covered, e.g. by bicycle 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. Active Blind Spot
Assist may otherwise no longer function prop-
erly.
Monitoring range G
WARNING
Active Blind Spot Assist does not detect all
traffic situations and road users. There is a
risk of an accident.
Always make sure that there is sufficient dis-
tance to the side for other traffic or obstacles. The detection of vehicles may be impaired in the
case of:
R dirt on the sensors or obscured sensors
R poor visibility, e.g. due to rain, snow or spray Vehicles in the monitoring range will then be
indicated late or not at all.
Active Blind Spot Assist may not detect narrow
vehicles, such as motorcycles or bicycles, or
may only detect them too late.
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.
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

The yellow indicator lamp goes out if reverse
gear is engaged. Active Blind Spot Assist is not
operational.
The brightness of the warning lamps is auto-
matically adapted to the brightness of the sur-
roundings.
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 then hear a double warning tone
and red warning lamp :flashes. If the turn sig-
nal remains on, detected vehicles are indicated
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 side
impact in the monitoring range, a course-cor-
recting brake application is carried out. This is
designed to help you avoid a collision. G
WARNING
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 if you steer slightly in the opposite
direction or accelerate. The course-correcting brake application is avail-
able in the speed range between 30 km/h and
200 km/h.
Either a course-correcting brake application
appropriate to the driving situation, or none at
all, may occur if:
R there are vehicles or obstacles, e.g. crash
barriers, on both sides of your vehicle
R a vehicle approaches too closely on the side
R you have adopted a sporty driving style with
high cornering speeds
R you clearly brake or accelerate
R a driving safety system intervenes, such as

Lane-correcting brake application
G
WARNING
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. G
WARNING
Active Lane Keeping Assist only detects traf-
fic conditions or road users to a limited
extent. In very rare cases, the system may
make an inappropriate brake application, e.g. after intentionally driving 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 to the side for
other traffic or obstacles. If you leave your lane under certain circumstan-
ces, the vehicle will brake briefly on one side.
This is intended to help you return the vehicle to
the original lane.
If a lane-correcting brake application occurs,
display :appears in the multifunction display.
A lane-correcting brake application can be made
after driving over a lane marking detected as
being solid or broken. Before this, a warning
must have been issued by means of intermittent
vibration through the steering wheel. In addi-
tion, a lane with lane markings on both sides
must be detected.
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.
i A further lane-correcting brake application
can only occur after your vehicle has returned
to the original lane.
No lane-correcting brake application occurs if: R you clearly and actively steer, brake or accel-
erate
R you cut the corner on a sharp bend
R you have adopted a sporty driving style with
high cornering speeds or high rates of accel-
eration
R you have switched on the turn signal
R a driving safety system intervenes, such as
ESP ®
, PRE-SAFE ®
Brake or Active Blind Spot

R the transmission is not in position D
R on vehicles with a trailer tow hitch, the elec-
trical connection to the trailer has been cor-
rectly established
R an obstacle has been detected in the lane in
which you are driving
R a loss of tyre pressure or a defective tyre has
been detected and displayed
There is a possibility that the Active Lane Keep-
ing Assist could misjudge the given traffic sit-
uation. An inappropriate brake application may
be interrupted at any time if:
R you steer slightly in the opposite direction
R you switch on the turn signal
R you clearly brake or accelerate
A lane-correcting brake application is interrup-
ted automatically if:
