Monitoring range of the sensors
In particular, the detection of obstacles can
be impaired in the case of:
dirt on the sensors or anything else cover-
R
ing the sensors
poor visibility, e.g. due to fog, heavy rain or
R
snow
narrow and short vehicles, e.g. motorcy-
R
cles or bicycles
very wide lanes
R
narrow lanes
R
vehicles not driving in the middle of their
R
lane
barriers or other road boundaries
R
Vehicles in the monitoring range are then not
indicated.
Blind Spot Assist monitors the area approx-
imately 10 ft (3.0 m) behind your vehicle and
approximately 1.6 ft (0.5 m) to 11.5 ft (3.5 m)
each side of it. For this purpose, Blind Spot
Assist uses radar sensors in the rear bumper
and behind the protective strips of the B-pil-
lars.
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:
a clear warning situation may not occur.
R
The yellow indicator lamp on the relevant
side of the vehicle will then light up.
warnings may be issued in error when driv-
R
ing close to crash barriers or similar solid
lane borders.
warnings may be interrupted when driving
R
alongside particularly long vehicles, for
example trucks, for a prolonged time.
The four sensors of Blind Spot Assist are inte-
grated into the rear bumper and behind the
protective strips of the B-pillars. Make sure
that the bumper and protective stripping are
free of dirt, ice or slush in the vicinity of the
sensors. The radar sensors must not be cov-
ered, for example by cycle racks or overhang-
ing loads.
Have the function of the radar sensors
checked at a qualified specialist workshop:
after a severe impact
R
after damage to the bumper
R
after damage to the protective strips of the
R
B-pillars
Blind Spot Assist may otherwise not work
properly.
Indicator and warning display
Blind Spot Assist is not active at speeds below
approximately 20 mph (30 km/h). Vehicles in
the monitoring range are then not indicated.
