WARNING
Active Blind Spot Assist does not react to
vehicles:
overtaking too closely on the side, placing
R
them in the blind spot area
if the difference in the speed of approach
R
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 grille. 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 function properly.
Monitoring range
G 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.
Active 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.
The detection of vehicles may be impaired in
the case of:
dirt on the sensors or obscured sensors
R
poor visibility, e.g. due to rain, snow or
R
spray
Vehicles in the monitoring range are then not
indicated.
Active Blind Spot Assist may not detect nar-
row vehicles, such as motorcycles or bicy-
cles, or may only detect them too late.
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:
warnings may be issued in error when driv-
R
ing close to crash barriers or similar solid
lane borders.
warnings may be interrupted when driving
R
alongside particularly long vehicles, for
example lorries, for a prolonged time.
