= There is no longer a risk of collision.
= An obstacle is no longer detected in front of
your vehicle.
Evasive Steering Assist (only vehicles with Driving
Assistance Package)
Evasive Steering Assist has the following charac-
teristics:
= The ability to detect stationary or moving
pedestrians.
= Assistance through power-assisted steering if
it detects a swerving manoeuvre. =
A ctivation by an abrupt steering movement
during a swerving manoeuvre.
= Assistance during swerving and straightening
of the vehicle.
= Reaction from a speed of approximately
20 km/h up to a speed of approximately
70 km/h.
You can prevent the assistance at any time by
actively steering.
Cornering function (only vehicles with Driving
Assistance Package)
If the system detects a risk of a collision with an
oncoming vehicle when turning across an oncom-
ing lane, autonomous braking can be initiated at
speeds below 15 km/h before you have les the
lane in which you are driving. &

Speed Limit Assist
Function of Speed Limit Assist
%
Speed Limit Assist uses OpenStreetMap data,
whic h is made available under the conditions
of the Open Database License (OBbL). For
more information, see: https://
www.osmfoundation.org/wiki/licence.
Speed Limit Assist detects speed limits with a
multifunction camer
a and displays them in the
instrument cluster and optionally in the head-up
display. The camera also detects speed limits with
a restriction indicated by an additional sign (e.g.
when wet). The system detects stop signs,
thereby preventing the engine from being
switched oM by the ECO start/stop function.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognise
dangers (  page 231).
Warning when the maximum permissible speed is
exceeded
The system can warn you if you unintentionally
exceed the maximum permissible speed. To do
this, you can specify in the multimedia system by
how much the maximum permissible speed can be exceeded before a warning is issued. You can
specify whe
ther the warning is to be just a visual
warning or an acoustic one as well.

ted. Speed Limit Assist is not available in all coun-
tries.
System limits
The system may be impaired or may not function
in the following situations:
= If there is poor visibility, e.g. due to insuPcient
illumination of the road, highly variable shade
conditions, rain, snow, fog or heavy spray.
= If there is glare, e.g. from oncoming traPc,
direct sunlight or reOections.
= If there is dirt on the windscreen in the vicinity
of the multifunction camera or if the camera is
misted up, damaged or obscured.
= If the traPc signs are hard to detect, e.g. due
to dirt, snow or insuPcient lighting, or
because they are covered. 260

raPc Sign Assist
TraPc Sign Assist detects traPc signs with the
multifunction camera ( page 231). It assists
you by displaying detected speed limits and over-
taking restrictions in the Instrument Display.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognise
dangers (  page 231).
Since TraPc Sign Assist also uses the data stored
in the navigation system, it can update the display
in the following situations without detecting traPc
signs.
If the system detects that you are driving onto a
section of road in the wrong direction of travel, it
triggers a warning.
The camera also detects traPc signs with a
restriction indicated by an additional sign (e.g.
when wet). These are only displayed if a restric-
tion applies or if the system cannot clearly deter-
mine whether the restriction applies. Warning when the maximum permissible speed is

WARNING Risk of accident despit e Active
Blind Spot Assist
Active Blind Spot Assist does not react to the
f
ollowing:
= if you overtake a vehicle too closely so that
it is in the blind spot area
= if vehicles travelling at a much faster
speed approach and then overtake
Active Blind Spot Assist may not give warnings
or intervene in such situations. 
Always pay careful attention to the tr
aPc
situation and maintain a safe distance at
the side of the vehicle. Observe the notes on driving systems and your
r
esponsibility; you may otherwise fail to recognise
dangers ( page 231).
Exit warning
The exit warning is an additional function of Blind
Spot Assist and can warn vehicle occupants about
approaching vehicles when leaving the vehicle
when stationary. &
WARNING Risk of accident despit
e exit
warning
The exit warning neither reacts to stationary
objects nor t
o persons or road users
approaching you at a greatly diMering speed.
The exit warning cannot warn drivers in these
situations. 
Always pay particular attention to the
tr
aPc situation when opening the doors
and make sure there is suPcient clear-
ance. If there is a vehicle in the monitoring range, this is
indicat

ed in the outside mirror. If a vehicle occu-
pant opens the door on the side with the warning,
a warning tone sounds and the warning lamp in
the outside mirror starts to Oash.
This additional function is only available when
Blind Spot Assist is active. When the exit warning
is activated, it can warn vehicle occupants for up
to three minutes aser switching the vehicle oM.
The exit warning is no longer available once the
warning lamp in the outside mirror Oashes three
times. The exit warning is only an aid and not a substi-
tut

e for the attention of vehicle occupants. The
responsibility for opening and closing the doors
and for leaving the vehicle remains with the vehi-
cle occupants.
System limits
Blind Spot Assist and Active Blind Spot Assist may
be limited in the following situations, in particular:
= if there is dirt on the sensors or the sensors
are obscured
= in poor visibility, e.g. due to fog, heavy rain or
snow
= if there are narrow vehicles, e.g. bicycles or
motorbikes
= if the road has very wide or narrow lanes
= if vehicles are not driving in the middle of their
lane
Warnings may be issued in error when driving
close to crash barriers or similar continuous lane
borders. Always make sure that there is suPcient
distance to the side for other traPc or obstacles. 264
Driving and parking

Warnings may be interrupted when driving along-
side long v
ehicles, for example lorries, for a pro-
longed time.
Blind Spot Assist is not operational when reverse
gear is engaged.
Blind Spot Assist and the exit warning are not
operational when a trailer is coupled to the vehi-
cle and the electrical connection has been cor-
rectly established.
The exit warning may be limited in the following
situations:
= when the sensors are covered by adjacent
vehicles in narrow parking spaces
= when people approach the vehicle
= in the event of stationary or slowly moving
objects
Function of brake application (Active Blind Spot
Assist)
If Active Blind Spot Assist detects a risk of a side
impact in the monitoring range, a course-correct-
ing brake application is carried out. This is
designed to help you avoid a collision. The course-correcting brake application is availa-
ble in t he speed range between approximately
30 km/h and 200 km/h. &
WARNING Risk of accident despit
e brake
application of Active Blind Spot Assist
A course-correcting brake application cannot
alw
ays prevent a collision. 
Always steer, brake or accelerate your-
self, especiall
y if Active Blind Spot Assist
warns you or makes a course-correcting
brake application. 
Always maintain a safe distance at the
sides. If a course-correcting brake application occurs,
t
he red warning lamp Oashes in the outside mirror
and a warning tone sounds. In addition, display
1 indicating the danger of a side collision
appears in the Instrument Display.
In rare cases, the system may make an inappro-
priate brake application. This brake application
may be interrupted at any time if you steer slightly
in the opposite direction or accelerate.
System limits
Note the system limitations of Active Blind Spot
Assist; you may otherwise not recognise the dan-
gers (  page 263).
Either a course-correcting brake application
appropriate to the driving situation, or none at all,
may occur in the following situations:
= Vehicles or obstacles, e.g. crash barriers, are
located on both sides of your vehicle.
= A vehicle approaches too closely on the side.
= You have adopted a sporty driving style with
high cornering speeds.
= You brake or accelerate signiNcantly. Driving and parking

Function of Active Lane Keeping Assist
A

ctive Lane Keeping Assist monitors the area in
front of your vehicle by means of the multifunction
camera (  page 231). It serves to protect you
against unintentionally leaving your lane. You will be warned by vibration pulses in the steering
wheel and guided b

y a course-correcting brake
application back into your lane.
Active Lane Keeping Assist is available in the
speed range between 60 km/h and 200 km/h.
Active Lane Keeping Assist can neither reduce the
risk of an accident if you fail to adapt your driving
style nor override the laws of physics. It cannot
take into account road, weather or traPc condi-
tions. Active Lane Keeping Assist is only an aid.
You are responsible for maintaining a safe dis-
tance to the vehicle in front, for vehicle speed, for
braking in good time and for staying in lane.
