fied specialist workshop. Blind Spot Assist may
no longer work properly in such cases.
Monitoring range
In particular, the detection of obstacles can be
impaired in the case of:
R
dirt on the sensors or obscured sensors
R
poor visibility, e.g. due to fog, heavy rain,
snow or spray
R
narrow vehicles, e.g. motorcycles or bicycles
R
very wide lanes
R
narrow lanes
R
vehicles not driving in the middle of their lane
R
crash barriers or other road boundaries
Vehicles in the monitoring range are then not
indicated.
At a distance of around 0.5 m ; from the vehi-
cle, Blind Spot Assist monitors the area up to
3.0 m next to = and behind : your vehicle, as
shown in the picture.
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 driv-
ing 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 driving
close to crash barriers or similar solid boun-
daries
R
warnings may be interrupted when driving
alongside long vehicles, e.g. lorries, for a pro-
longed time
Warning lamp
: Warning lamp
Blind Spot Assist is not active at speeds below
approximately 30 km/h. Vehicles in the moni-
toring range are then not indicated.
If a vehicle is detected within the blind spot
monitoring range at speeds above approx-
imately 30 km/h, warning lamp : on the cor-
responding side lights up red. This warning lamp
always lights up when a vehicle enters the blind
spot monitoring range from behind or from the
side. When you overtake a vehicle, the warning
occurs only if the difference in speed is less than
12 km/h.
If you select reverse gear, Blind Spot Assist is
not operational.
The brightness of the warning lamps is auto-
matically adapted to the brightness of the sur-
roundings.
Collision warning
If a vehicle is detected in the blind spot moni-
toring range and you switch on the correspond-
ing turn signal, a double warning tone sounds.
The red warning lamp flashes on the relevant
exterior mirror. If the turn signal remains on,
detected vehicles are indicated by the flashing
of the red warning lamp on the exterior mirror.
There are no further warning tones.
