ynotes G
WARNING
Active Blind Spot Assist is only an aid and may
detec tvehicles/obstacles incorrectly or not
at all.
The system may be impaired or may not func-
tion if:
R there is poor visibility, e.g. due to snow,
rain, fog or spray.
R the rear and/or fron tsensor sare dirty.
Active Blind Spot Assist may not detect nar-
row vehicles, such as motorcycles or bicycles,
or only detect them too late. It cannot detect
vehicles which are overtaken at asmall dis-
tanc eand then enter the blind spot area.
Active Blind Spot Assist cannot detect road
and traffic conditions .Itisnotas ubstitute for
attentive driving. You are responsible for the
vehicle's speed, braking in good time, and
steering correctly. Always adapty our driving
style to suit the prevailing road and weather
conditions. Always pay attention to traffic
conditions and your surroundings. Otherwise,
you may fail to recognise dangers in time,
cause an accident and injure yourself and oth-
ers.
General notes
Active Blind Spot Assist uses aradar sensor
system to monitor the area to the sides of
your vehicle which are behind the driver. A
warning display in the exterior mirrors draws
your attention to vehicles detected in the
monitored area. If you then switch on the cor-
responding turn signal to change lane, you
will also receive an optical and audible warn- ing. If
arisk of lateral collision is detected,
corrective braking may help you avoid acol-
lision. To support the course-correcting brake
application, Active Blind Spot Assist uses the
forward-facin gradar sensor system. The free
space in the direction of travel is then evalu-
ated.
Active Blind Spot Assist supports you from a
speed of approximately 30 km/h.
The radar sensor system is switched off auto-
matically in the vicinit yofradio telescope
facilities (Y page 368).
For Active Blind Spot Assist to assist you
when driving, the radar sensor system must
be activated (Y page 225) and operational.
Monitoring range G
WARNING
Active Blind Spot Assist monitors certain
areas in the immediate vicinit yofyour vehicle.
Vehicles that approach and drive past at high
speeds are not detected. No visual nor audi-
ble warnings are emitted and the system does
not brake the vehicle to correc tyour course.
If the lanes are very wide, it may not be pos-
sible to monitor the complete width of the
neighbouring lane. For this reason, vehicles in
the next lane may not be detected, especially
if they are driving in astaggered formation.
This may be the case if vehicles are driving at
the edge of their lane that is furthest away
from your vehicle.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourself and others. Driving systems

If yo uswitch on the turn signals to change
lanes and avehicl eisd etected in the side
monitoring range, yo ureceive avisua land
acoustic collision warning .You then hear a
double warning tonea nd red warning
lamp :flashes. If the turn signal remains on,
detected vehicles are indicated by the flash-
ing of red warning lamp :.There are no fur-
ther warning tones.
Course-correcting brake application G
WARNING
Active Blind Spot Assist is only an aid
designed to assist driving. It is not asubstitute
for attentive driving. Automatic braking by the
system may not always be sufficient to avoid
ac ollision. In such cases, you need to steer,
brake or accelerate yourself.
In very rare cases, the system may detect a
risk of collision where there is none and brake
in error near crash barriers or similar road
boundaries. Active Blind Spot Assist cannot
detect all traffic situations and road users.
Ensure at all times that there is sufficient lat-
eral distance between you and other road
users or obstacles. You can, for example,
countersteer gently or depress the accelera-
tor pedal at any time to cancel inappropriate
braking action.
You are responsible for the vehicle's speed,
correct steering and for braking in good time.
Always adapt your driving style to suit the
prevailing road and weather conditions.
Always pay attention to traffic conditionsa nd
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourself and others. If Active Blind Spot Assist detectsar
isk of a
lateral collision in the monitoringr ange, a
course-correcting brake application is carried
out. This is designed to help you avoid acol-
lision.
If ac ourse-correcting brake application
occurs, red warning lamp :flashes in the
exterior mirror and adual warning tone
sounds. In addition, the message shown in
the illustration appears in the multifunction
display.
The course-correctingb rake application is
available in the speed range between
30 km/h and 200 km/h.
Either no braking application, or acourse-
correcting brake application adapted to the
driving situation occurs if
R there are vehicles or obstacles, e.g. crash
barriers, on both sides of your vehicle.
R av ehicle approaches too closely on the
side.
R you have adopted asporty driving style with
high cornering speeds.
R you brake or accelerate decisively.

Lane-correcting brak eapplication G
WARNING
Active Lane Keeping Assist does not keep
your vehicle in its lane. It is only an aid
designed to assist driving. It is not asubstitute
for attentive driving. Corrective braking may
not alway sbesufficien ttoreturn your vehicle
to its original lane. In such cases, you must
steer the vehicle yourself to ensure that it
does not leave the lane.
Active Lane Keeping Assist cannot detect the
current traffic situation or other road users.
Ensure at all times that there is sufficient lat-
eral distance between you and other road
users or obstacles. In rare cases, broken lines
or certain structures on the road surface may
be detected by the system as solid lane mark-
ings. You can, for example, countersteer gen-
tly at any time to cancel inappropriate braking
action, e.g. if you intentionally drive across a
solid lane marking.
Active Lane Keeping Assist cannot take
weather conditions into account.
You are responsible for the vehicle's speed,

Alway sadapt your drivin gstyle to suit the prevailing road and weather conditions.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourself and others. The message shown in the illustration
appears in the multifunction display when a
lane-correcting brake application occurs.
If you leave your lane under certain circum-
stances, the vehicle will brake briefly on one
side. This is designed to help you bring the
vehicle back into the original lane.
This function is available in the range between
60 km/ha nd 200 km/h.
Al ane-correcting brake application can only
be made after driving over asolid, recognis-
able lane marking. Before this, awarning
must be emitted by means of intermittent
vibration in the steering wheel. In addition, a
lane with lane markings on both sides must
be recognised. The brake application also
slightly reduces driving speed.
i Afurther lane-correcting brake applica-
tion can only occur after your vehicle has
returned to the original lane.
No lane-correcting brake application occurs
