Monitoring range of the sensors
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. motorcycle sorbicy-
cles
R very widel anes
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 mbehind your vehicle and directly nextto
your vehicle, as shown in the diagram.
If the lanes are narrow, vehicles driving in the
lane beyond the lane nexttoy our vehicle may
be indicated, especially if the vehicles are not
driving in the middle of their lane. This may be the case if ther eare 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 aprolonged time
The two radar sensor sfor Blind Spot Assist
are integrated intot he 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 rack soroverhanging loads. Fol-
lowing asevere impact or in the event of dam-
age to the bumpers, have the function of the
sensor schecked at aqualified specialist
workshop. Blind Spot Assist may otherwise
not work properly.

Active Blind Spot Assist General notes
Active Blind Spot Assist monitors the areas
on either side of the vehicle that are not visi-
ble to the driver with two lateral, rear-facing
radar sensors. Awarning display in the exte-
rior mirrors draws your attention to vehicles
detected in the monitored area. If you then
switch on the corresponding turn signal to
change lanes, you will also receive avisual
and audibl ecollision warning. If arisk of side
impact is detected, corrective braking may
help you avoid acollision. Active Blind Spot
Assist evaluates the free space in the direc-
tion of travel and to the side before making a course-correcting brake application. For this,Active Blind Spot Assist uses the forward-
facing radar sensors.
Active Blind Spot Assist supports you from a
speed of approximately 30 km/h.
Important safety notes
Active Blind Spot Assist is only an aid and is
not asubstitute for attentive driving. G
WARNING
Active Blind Spot Assist does not react to
vehicles:
R overtaking too closely on the side, placing
them in the blind spot area
R if the differenc einthe speed of approach
and overtaking is too great As
aresult, Active Blind Spot Assist may nei-
ther give warnings nor intervene in such sit-
uations. There is arisk of an accident.
Always pay careful attention to the traffic sit- uation and maintain asafe distanc eatthe side
of the vehicle.
Radar sensors
The Active Blind Spot Assist radar sensors are integrated into the fronta nd rear bumpers
and behind acover in the radiator trim. Make
sure that the bumpers and the cover in the
radiator trim are free of dirt, ice or slush. The
rear sensors must not be covered, e.g. by
bicycle racks or overhangin gloads. Following
as evere impact or in the event of damage to
the bumpers, have the function of the radar
sensors checked at aqualified specialist
workshop. Active Blind Spot Assist may oth-
erwise no longer function properly.
