sists of DISTRONIC PLUS (Y page 171), Active
Blind Spot Assist (Y page 199) and Active
Lane Keeping Assist (Y page 202).
Active Blind Spot Assist Important safety notes
Active Blind Spot Assist uses
aradar sensor
system to monitor the side areas of your vehi- cle that are behind the driver.
Awarning dis-
play in th eexteri or mirror sdraws your atten-
tio ntod etected vehicles in the monitored
area. If you then switch on the corresponding
turn signal to change lane, you will also
receive avisual and acoustic collision 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 also uses
the forward-facin gradar sensor system.
Active Blind Spot Assist provides assistance
at speeds higher than about 30 km/h. G
WARNING
Active Blind Spot Assist is only an aid and may
detect vehicles/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 front sensors are 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-
tancea nd then enter the blind spot area.
Active Blind Spot Assist cannot detect road
and traffic conditions. It is not asubstitute for
attentive driving. You are responsible for the
vehicle's speed, braking in good time, and
steering correctly. Always adapt your 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.
The radar sensor system is automatically
deactivated near radio telescope facilities
(Y page 345).
For Active Blind Spot Assist to assist you
when driving, the radar sensor system must
be activated (Y page 229) and operational. Driving systems

Warning vibration in th esteering wheel
Aw arnin gmay be given if afront wheel
passes over alane marking. You will be
warned by way of intermitten tvibrations in
the steerin gwheel for up to 1. 5seconds.
In order that you are warned only when nec-
essary and in good time if you cross the lane
marking, the system recognises certain con-
ditions and warns you accordingly.
The warning vibration occur searlier if:
R you approach the outer lane markin gona

R the road has very wide lanes, e.g. amotor-
way.
R the system recognises solid lane markings.
The warning vibration occur slater if:
R the road has narrow lanes.

No warning vibration occur sif:
R you clearly and actively steer ,brake, or
accelerate.
R you cut the corner on asharp bend.

eapplication
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 intot he original lane.
This function is available in the range between
60 km/ha nd 200 km/h.
Al ane-correctingb rake application can only
be made after driving over asolid, recognis-
able lane marking. Befor ethis, 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.
If al ane-correcting brake application occurs,
the following message appears in the multi-
function display: Example: vehicles with automatic transmission
i
Afurther lane-correcting brake applica-
tion can only occur after your vehicle has
returned to the original lane. 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 always be sufficient to return 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- Driving systems
