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-

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.
