Monitoring range of the sensors
In particular, the detection of obstacles can
be impaired if: R
there is dirt on the sensors or anything else
covering the sensors R
there is poor visibility, e.g. due to fog, heavy
rain or snow R
a narrow vehicle traveling in front, e.g. a
motorbike or bicycle R
the road has very wide lanes R
the road has narrow lanes R
you are not driving in the middle of the lane R
there are barriers or similar lane borders
Vehicles in the monitoring range are then not
indicated.
Blind Spot Assist monitors the area up to 10 ft
(3 m) behind your vehicle and directly next to
your vehicle, as shown in the diagram.
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 issued in error when driv-
ing close to crash barriers or similar solid
lane borders. R
warnings may be interrupted when driving
alongside particularly long vehicles, e.g.
trucks, for a prolonged time.

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.
When Blind Spot Assist is activated, indicator
lamp C in the exterior mirrors lights up yel-
low at speeds of up to 20 mph (30 km/h). At
speeds above 20 mph (30 km/h), the indica-
tor lamp goes out and Blind Spot Assist is
operational.
If a vehicle is detected within the blind spot
monitoring range at speeds above 20 mph
(30 km/h), warning lamp C on the corre-
sponding side lights up red. This warning is
always emitted when a vehicle enters the
blind spot monitoring range from behind or
from the side. When you overtake a vehicle,
the warning only occurs if the difference in
speed is less than 7 mph (12 km/h).
The yellow indicator lamp goes out if reverse
gear is engaged. In this event, Blind Spot
Assist is no longer active.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the ambient light.214
