Radar sensors
The radar sensors for Blind Spot Assist are inte-
grated into the rear bumper. Make sure that the
bumpers are free from dirt, ice or slush. The
sensors must not be covered, for example by
cycle 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.
Blind Spot Assist may no longer work properly.
Monitoring range of the sensors
In particular, the detection of obstacles can be
impaired in the case of:
R
dirt on the sensors or obscured sensors
R
poor visibility, e.g. due to fog, heavy rain or
snow
R
narrow vehicles, e.g. motorcycles or bicycles
Vehicles in the monitoring range are then not
indicated.
Blind Spot Assist monitors the area up to 3.0 m
behind your vehicle and directly next to your
vehicle, as shown in the picture.
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.
On very wide lanes, vehicles in the lane next to
your vehicle may not be displayed if the vehicles
are too far away.
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 long vehicles, for example lorries,
for a prolonged time
Warning display
Blind Spot Assist is not active at speeds below
approximately 30 km/h. Vehicles in the moni-
toring range are then not indicated.
:
Yellow indicator lamp/red warning lamp
If Blind Spot Assist is activated, indicator
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 Blind
Spot Assist is operational.
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 always
occurs 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.
The yellow indicator lamp goes out if reverse
gear is engaged. Blind Spot Assist is then deac-
tivated.
The brightness of the indicator/warning lamps
is adjusted automatically according to the ambi-
ent light.
Collision warning
If a vehicle is detected in the monitoring range of
Blind Spot Assist and you switch on the corre-
sponding turn signal, a double warning tone
sounds. Red warning lamp
:
flashes. If the turn
signal remains on, detected vehicles are indica-
