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 trim. Make sure
that the bumpers and the cover in the radiator
trim are free of dirt, ice or slush. The sensors
must not be covered, for example by cycle racks
or overhanging loads. Following an accident or
in the event of damage to the bumpers, have the
function of the radar sensors checked at a quali-
fied specialist workshop. Active Blind Spot
Assist may otherwise no longer function prop-
erly.
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.
In particular, the detection of obstacles can be
impaired in the case of:
dirt on the sensors or obscured sensors
R
poor visibility, e.g. due to rain, snow or spray
R
Vehicles in the monitoring range are then not
reliably indicated.
Active Blind Spot Assist may not detect narrow
vehicles, such as motorcycles or bicycles, 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 driv-
ing in the middle of their lane. This may be the
case if there are vehicles at the edge of their
lane.
Due to the nature of the system:
warnings may be issued in error when driving
R
close to crash barriers or similar solid lane
borders
warnings may be interrupted when driving
R
alongside particularly long vehicles, for exam-
ple lorries, for a prolonged time
Indicator and warning display
Yellow indicator lamp/red warning lamp
:
Active Blind Spot Assist is not operational at
speeds below approximately 30 km/h. Vehicles
in the monitoring range are then not indicated.
If Active Blind Spot Assist is switched on, indi-
cator lamp : in the exterior mirrors lights up
yellow up to a speed of 30 km/h. At speeds
above 30 km/h, the indicator lamp goes out and
Active Blind Spot Assist is operational.
If a vehicle is detected within the monitoring
range at speeds above 30 km/h, warning
lamp : on the corresponding side lights up red.
This warning lamp always lights up when a vehi-
cle enters the blind spot monitoring range from
behind or from the side. When you overtake a
