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:
R
dirt on the sensors or obscured sensors
R
poor visibility, e.g. due to rain, snow or spray
Vehicles in the monitoring range are then not
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
nearest your vehicle.
Due to the nature of the system:
R
warnings may be issued in error when driving
close to crash barriers or similar solid lane
borders
R
warnings may be interrupted when driving
alongside particularly long vehicles, for exam-
ple lorries, for a prolonged time
Warning display

Warning display
Active Blind Spot Assist is not operational at
speeds below approximately 30 km/h. Vehicles
in the monitoring range are then not indicated.
If a vehicle is detected within the monitoring
range of Blind Spot Assist at speeds above
30 km/h, warning lamp
:
on the correspond-
ing side lights up red. This warning lamp always
lights up when a vehicle enters the blind spot
monitoring range from behind or from the side.
When you overtake a vehicle, the warning only
occurs if the difference in speed is less than
12 km/h.
If you select the reverse gear, Active Blind Spot
Assist is not operational.
The brightness of the warning lamps is auto-
matically adapted to the brightness of the sur-
roundings.
When Active Blind Spot Assist is activated, grey
radar waves propagating rearwards appear next
to the vehicle in the assistance display in the
multifunction display. Above a speed of
30 km/h, the colour of the radar waves in the
assistance display changes to green
;
. Active
Blind Spot Assist is then ready for use.
