the edge of their lane tha
tisfurthest away
from your vehicle.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yoursel fand others. Active Blind Spo
tAssist monitor sthe area up
to 3. 0mbehind your vehicle and directly next
to your vehicle, as shown in the diagram. For
this purpose, Active Blin dSpot Assist uses
rada rsensors in the rear bumper.
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 inner
edge of your 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 inter rupted when driving
alongside particularly long vehicles, for
example lorries, for aprolonged time.
Th eA ctive Blind Spo tAssist radar sensor sare
integ rated into the front and rear bumpers
and behind acover in the radiator grille. Make
sure that the bumpers and the cover in the
radiator grille ar efree of dirt, ice or slush. The rea
rsensors must not be covered, e.g. by
bicycle racks or overhanging loads. Following
as ever eimpact or in th eevent of damag eto
the bumpers, have the function of the radar
sensors checked at aqualified specialist
workshop. Active Blind Spot Assis tmay oth-
erwise no longer work properly.

In very rare cases, the system may detect a
risk of collision where there is none and brake
in error near crash barriers or similar road
boundaries .Active Blind Spot Assist cannot
detect all traffic situations and road users.
