Active Blind Spot Assist
General notes
Active Blind Spot Assist uses a radar sensor
system, pointed toward the rear of the vehi-
cle, to monitor the area to the sides of the
vehicle which the driver is unable to see. A
warning display in the exterior mirrors draws
your attention to vehicles detected in the
monitored area. If you then switch on the cor-
responding turn signal to change lanes, you
will also receive an optical and audible colli-
sion warning. If a risk of side impact is detec-
ted, corrective braking may help you avoid a
collision. Before a course-correcting brake
application, Active Blind Spot Assist evalu-
ates the space in the direction of travel and
at the sides of the vehicle. For this, Active
Blind Spot Assist uses radar sensors which
are pointed in the direction of travel.
Active Blind Spot Assist supports you from a
speed of approximately 30 km/h.
For Active Blind Spot Assist to assist you
when driving, the radar sensor system must
be:
R
activated(

Important safety notes
Active Blind Spot Assist is only an aid and is
not a substitute for attentive driving.

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 difference in the speed of approach
and overtaking is too great
As a result, Active Blind Spot Assist may nei-
ther give warnings nor intervene in such sit-
uations. There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and maintain a safe distance at the side
of the vehicle.
Radar sensors
The Active Blind Spot Assist radar sensors are
integrated into the front and rear bumpers
and behind a cover in the radiator grill. Make
sure that the bumpers and the cover in the
radiator grille are free of dirt, ice or slush. The
rear sensors must not be covered, e.g. by
bicycle racks or overhanging loads. Following
a severe impact or in the event of damage to
the bumpers, have the function of the radar
sensors checked at a qualified specialist
workshop. Active Blind Spot Assist may oth-
erwise no longer work properly.

WARNING
Active Blind Spot Assist does not detect all
traffic situations and road users. There is a
risk of an accident.
Always make sure that there is sufficient dis-
tance to the side for other traffic or obstacles.
