Blind Spot Assist Important safety notes
G
WARNING
Blind Spot Assist is only 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. G
WARNING
Blind Spot Assis tisn ot active at speeds below
30 km/h. The indicator lamps in the exterior
mirror sare yello w.Vehicle sinthe monitoring
range ar ethen not indicated.
Always pay attention to traf ficc ondition sand
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourself and othe rs.
Ge nera lnotes
Blind Spot Assist uses aradar senso rsystem
to monitor the areas on both side sofyour
vehicle. It supports you from speeds of
30 km /h.Aw arning display in the exterior
mirror sdraws your attentio ntovehicles
detected in the monitored area .Ifyou then

change lane, yo
uwilla lsor eceive an optical
and audible collisio nwarning. For monitoring,
Active Blin dSpot Assist uses sensors in the
rear bumper.
For Blin dSpot Assist to assist you when driv-
ing, the rada rsensor system must be activa-
ted (Y page 283) and operational.
The rada rsensor system is switched off auto-
maticall yinthe vicinit yofradio telescope
facilities (Y page 433).
Monitoring range of the sensors G
WARNING
Blind Spot Assist monitors certain 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. Blind Spot Assis
tmonitors the area up to
3. 0mb ehind your vehicle and direc tlyn extto
your vehicle, as shown in the diagram.
If the lanes are narrow, vehicles drivin gint he
lan ebeyond th elan en ext to your vehicle may
be indicated, especially if th evehicles are not
drivin gint he midd le of their lane. This may
be th ecase if there are vehicles at th eedge
of their lan eneares tyour vehicle.
Due to th enature of th esystem:
R warnings may be issued in error when driv-
ing close to crash barriers or similar solid
lane borders.
R warnings may be interrupted when driving
alongside long vehicles, for example lor-
ries, for aprolonged time.
Th et wo radar sensors for Blin dSpot Assist
are integrated int othe sides of the rear
bumper .Make sure that the bumper is free of
dirt, ice or slush in the vicinity of the sensors.
The sensor smust not be covered, for exam-
ple by cycle racks or overhanging loads .Fol-
lowin gasevereimpact or in th eevent of dam-
ag etot he bumpers, hav ethe function of the
sensor schecked at aqualified special ist
workshop. Blind Spot Assist may otherwise
not work properly.

If
av ehicle is detected within the monitoring
range of Blin dSpot Assist at speed sabove
30 km/h, warning lamp :on the corre-
sponding side lights up red. This warning
alway soccurs whe navehicle enter sthe blind
spot monitoring range from behind or from
the side. When you overtak eavehicle, the
warning only occurs if the difference in speed
is less than 12 km/h.
The yellow indicator lam pgoes out if reverse

WARNING
Active Blind Spo tAssist is only an aid and may

Active Blind Spot Assist may not detect nar-
row vehi cles, such as motorcycles 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.
The radar sensor syste misautomatically

For Active Blind Spot Assis ttoassist you
when driving, the radar sensor syste mmust

General notes
Active Blind Spot Assist use saradar 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 brakin gmay help you avoid acol-
lision. To suppor tthe course- correcting brake
application ,Active Blind Spo tAssist uses the
forward-facin gradar senso rsystem. The free
space in the direction of travel is then evalu-
ated.
Active Blind Spot Assist supports you from a
speed of approximatel y30km/h.
Monitorin grange G
WARNING
Active 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. No visual nor audi-
ble warnings are emitted and the system does
not brake the vehicle to correc tyour course.
If the lanes are ver ywide, 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 drivin ginastaggered formation.

recognise dangers in time, cause an accident
and injure yoursel fand others. Active Blind Spo
tAssist monitor sthe area up
to 3. 0mbehind your vehicle and directly next
to your vehicle, as shown in the diagram. For
this purpose, Active Blin dSpot Assist uses
rada rsensors in the rear bumper.
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 there are vehicles at the inner
edge of your lane.
Due to the nature of the system:
R warnings may be issued in error when driv-
ing close to crash barriers or similar solid
lane borders.
R warnings may be inter rupted when driving
alongside particularly long vehicles, for
example lorries, for aprolonged time.
Th eA ctive Blind Spo tAssist radar sensor sare

and behind acover in the radiator grille. Make
sure that the bumpers and the cover in the
radiator grille ar efree of dirt, ice or slush. The rea

Indicator and warning display G
WARNING
Active Blind Spot Assist is not active at speeds
below 30 km/h. The indicator lamps in the
exterior mirrors are yellow .Vehicles in the
moni toring range are then not indicated.
Always pay attention to traffic conditions and
