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

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.
