Monitoring range of the sensors
In particular, the detection of obstacles can
be impaired in the case of:
R
dirt on the sensors or the sensors are
obscured
R
poor visibility, e.g. due to fog, heavy rain,
snow or spray
R
narrow vehicles, e.g. motorcycles or bicy-
cles
R
very wide lanes
R
narrow lanes
R
vehicles not driving in the middle of their
lane
R
barriers or other road boundaries
Vehicles in the monitoring range are then not
indicated.
Example: Saloon
Blind Spot Assist monitors the area up to
3.0 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 there are vehicles at the edge
of their lane nearest your vehicle.
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 long vehicles, for example lor-
ries, for a prolonged time.
The two radar sensors for Blind Spot Assist
are integrated into the sides of the rear
bumper. Make sure that the bumper is free of
dirt, ice or slush in the vicinity of the sensors.
The sensors must not be covered, for exam-
ple by cycle racks or overhanging loads. Fol-
lowing a severe impact or in the event of dam-
age to the bumpers, have the function of the
sensors checked at a qualified specialist
workshop. Blind Spot Assist may otherwise
not work properly.
Indicator and warning display
:
Yellow indicator lamp/red warning lamp
Blind Spot Assist is not active at speeds below
approximately 30 km/h. Vehicles in the mon-
itoring range are then not indicated.
If Blind Spot Assist is activated, indicator

in the exterior mirrors lights up yel-
low up to a speed of 30 km/h. At speeds
above 30 km/h, the indicator lamp goes out
and Blind Spot Assist is operational.
If a vehicle is detected within the monitoring
range of Blind Spot Assist at speeds above
30 km/h, warning lamp

on the corre-
sponding side lights up red. This warning
always occurs when a vehicle enters the blind
spot monitoring range from behind or from
