Monitoring range of the sensors
Blind Spot Assist monitors the area up to
three metres behind yourv ehicle and directly
nextt o your vehicle, as shown in the diagram. G
WARNING
Blind Spot Assist monitors certain areas in the
immediate vicinity of your vehicle. Vehicles
that approach and drive past at high speeds
are not detected. There is no display and no
warning.
If the lanes are very wide, it may not be pos-
sible to monitor the complete width of the
neighbouring lane. For this reason, vehicles in
the next lane may not be detected, especially
if they are driving in a staggered formation in
different lanes. This may be the case if vehi-
cles are driving at the edge of their lane that
is furthest 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 yourself and others.
If the lanes are narrow, the system may be
unable to distinguish the neighbouring lane
from the one beyond it. For this reason, vehi-
cles in the farther lane may be indicated,
especially if the vehicles are driving in a stag-
gered formation in different lanes. In particu-
lar, this may be the case if the vehicles are driving at the edge of their lane nearest your
vehicle.
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 interrupted when driving
alongside particularly long vehicles, for
example lorries, for a prolonged time.
The two sensors for Blind Spot Assist are
integrated into the sides of the rear bumper.
Make sure that the bumper is free of dirt, ice
or slush around the sensors. For example, the
radar sensors must not be covered 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, e.g. a Mercedes-Benz Service
Centre. Blind Spot Assist may otherwise not
work properly.
Indicator and warning display :
Yellow indicator lamp/red warning lamp
If Blind Spot Assist is switched on, indicator
lamp :in the exterior mirrors lights up yel-
low 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 corre-
sponding side lights up in red. This warning is
always emitted when a vehicle enters the
blind spot monitoring range from behind or Driving systems

Active Blind Spot Assist Important safety notes
Active Blind Spot Assist uses a radar sensor
system to monitor the side areas of your vehi-
cle that are behind the driver. Awarning dis-
play in the exterior mirrors draws your atten-
tio nt o detected vehicles in the monitored
area. If you then switch on the corresponding
turn signal to change lane, you will also
receive a visual and acoustic collision warn-
ing. If a risk of lateral collision is detected,
corrective braking may help you avoid a col-
lision. To support the course-correcting brake
application, Active Blind Spot Assist also uses
the forward-facing radar sensor system.
Active Blind Spot Assist provides assistance
at speeds higher than about 30 km/h. G
WARNING
Active Blind Spot Assist is only an aid and may
detect vehicles/obstacles incorrectly or not
at all.
The system may be impaired or may not func-
tion if:
R there is poor visibility, e.g. due to snow,
rain, fog or spray.
R the rear and/or front sensors are dirty.
Active Blind Spot Assist may not detect nar-
row vehicles, such as motorcycles or bicycles,
or only detect them too late. It cannot detect
vehicles which are overtaken at a small dis-
tance and then enter the blind spot area.
Active Blind Spot Assist cannot detect road
and traffic conditions. It is not a substitute for
attentive driving. You are responsible for the
vehicle's speed, braking in good time, and
steering correctly. Always adapt your driving style to suit the prevailing road and weather
conditions. Always pay attention to traffic
conditions and your surroundings. Otherwise,
you may fail to recognise dangers in time,
cause an accident and injure yourself and oth-
ers.
The radar sensor system is automatically
deactivated near radio telescope facilities
(Y page 363).
For Active Blind Spot Assist to assist you
when driving, the radar sensor system must
be activated (Y page 226) and operational.
Monitoring range
Active Blind Spot Assist monitors the area up
to three metres behind your vehicle and
directly next to your vehicle, as shown in the
diagram. For this purpose, Active Blind Spot
Assist uses radar sensors in the rear bumper. G
WARNING
Active Blind Spot Assist monitors certain
areas in the immediate vicinity of your vehicle.
Vehicles that approach and drive past at high
speeds are not detected. No visual nor audi-
ble warnings are emitted and the system does
not brake the vehicle to correct your course.
If the lanes are very wide, it may not be pos-
sible to monitor the complete width of the
neighbouring lane. For this reason, vehicles in 194
