Blind Spot Assist Important safety notes
Blin dSpot Assist uses aradar senso rsystem
to monitor the areas on both side sofyour
vehicle. It supports you from speeds of
30 km/h. Awarning displ ay inthee xterior
mirrors draws your attention to vehicles
detected in the monitored area. If you then
switch on the corresponding turn signal to
chang elane, you will also receive an optical
and audible collisio nwarning. For monitoring,
Active Blind Spot Assis tuses sensor sinthe
rea rbumper. G
WARNING
Blind Spot Assis tiso nly an aid designe dto
assis tdriving. It may fail to detec tsome vehi-
cles and is no substitute for attentive driving.
Blin dSpot Assist cannot detect road and traf-
fic conditions. It may fail to detect narrow
vehicles, such as motor cycles or bicycles ,or
only detec tthem too late.
Monitorin gmay be affected by dirty sensors,
stron gspray or poor visibility caused by snow,
rain or mist, for example. In this case, vehicles
are detected late or not at all.
Alway spay attention to traffic conditions and
your surroundings. Otherwise ,you may fai lto
recognise dangers in time ,cause an accident
and injure yourself and others.
The radar senso rsystem is automatically
deactivated near radio telescope facilities
(Y page 380).
For Blind Spot Assist to assist you when driv-
ing, the radar sensor syste mmust be activa-
ted (Y page 249 )and operational. 208

Mon
itoring range of the sensors
Blind Spot Assist monitors the area up to
three metres behind you rvehicle and direc tly
next to you rvehicle, as shown in the diagram. G
WARNING
Blin dSpot Assist monitors cer tain areas in the
immediate vicinit yofyour vehicle. Vehicles
that approach and driv epast at high speeds
are not detected. There is no display and no
warning.
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 in
different lanes .This ma ybethe case if vehi-
cles ar edriving at th eedge of their lane that
is furthest away from your vehicle.
Alway spay attention to traffic conditions and
your surroundings. Otherwise ,you may fai lto
recognis edangers in time, cause an accident
and injure yourself and others.
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
driving in the middle of their lane. This may
be the case if the vehicles are driving on the
inner side of their lane. Due to the nature of the system:
R
warnings may be issue dine rror when driv-
ing close to cras hbarriers or similar solid
lane borders.
R warnings may be interrupted when driving
alongside long vehicles, such as lorries, for
ap rolonged time.
Th et wo 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 vicinit yofthe sensors. The
radar sensor smust not be covered, for exam-
ple by cycle racks or overhanging loads .Fol-

ag etot he bumpers, hav ethe func tion of the
radar sensor schecked at aqualified special-
ist workshop, e.g. aMercedes-Ben zService

Active Blind Spot Assist Important safety notes
Active Blin dSpot Assist uses aradar sensor
system to monitor the side areas of your vehi-
cle which are in back of the driver. Awarning
display in the exter iormirror sdraws your
attention to vehicles detected in the moni-
tored area. If you then switch on the corre-
sponding turn signal to change lane, you will
also receive an optical and audible collision
warning. If arisk of lateral collision is detec-
ted, corrective brakin gmay help you avoid a
collision. To support the course-correcting
brake application, Active Blind Spot Assist
also uses the forward-facin gradar senso rsys-
tem. Active Blind Spot Assist supports you
from aspeed of approximately 30 km/h. G
WARNING
Active Blin dSpot Assist is only an aid and may
detect vehicles/obstacles incor rectly or not
at all. Th
es ystem may be impaired or may not func-
tion if:
R there is poo rvisibility, e.g. due to snow,
rain, fog or spray.
R the rear and/or fron tsensors are dirty.
Active Blin dSpot Assist may not detect nar-
row vehicles, such as motor cycles or bicycles,
or only detect the mtoo late. It can notd etect
vehicles which are overtaken at asmall dis-
tance and then enter th eblind 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.

WARNING
Active Blind Spo tAssist monitor scertain
areas in the immediate vicinity of your vehicle.
Vehicles that approach and drive past at high
speeds are not detected. No visual nor audi-
ble warnings are emitted and the syste mdoes
not brake the vehicle to cor rect your course.
If the lane sare very wide, it may not be pos-
sibl etom onitor the complet ewidth of the
neighbourin glane. For this reason, vehicles in
the nex tlane may not be detected, especially
if they are driving in astaggered formation.
Thi sm ay 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.
If the lanes are narrow, vehicles driving in the
lane beyond the lane nex ttoyour vehicle may
be indicated, especially if the vehicles ar enot
drivin ginthe middle of their lane. This may
be the case if ther eare vehicles at th eedge
of their lane nearest your vehicle. Due to the nature of the system:
R
warnings may be issued in error when driv-

Activ eBlindS pot 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 sufficien ttoavoid

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 betwee nyou and other road
users or obstacles. You can ,for example,
