Important safety notes
GWARNING
Blin dSpo t Assist does not react to:
Rvehicles overtaken too closely on the side,
plac ing them inthe blind spot area
Rvehicleswhic happr oach with a large speed
diff erential and overtake your veh icle
As a result, BlindSpo t Assist may not give
warnings insuch situations. There isa risk of
an acc ident.
Always observe the traff icconditions care-
fully, and maintain a safe lateral distance.
Blin dSpo t Assist isonly anaid. It may fail to
detect some vehicles and isno substitute for
attentive driving. Always ensure that there is
suff icientdist ance to the sidefor other road
users and obstacles.
iUSA only:
This device has been approved bythe FCC as
a "Vehicular Radar System". The radar sensor
is intended for use inan automotive radar
system only. Removing, tampering with, or
altering the device willvoid any warranties,
and isnot permitted bythe FCC. Do not tam-
per with, alter, or use inany non- approved
way.
Any unauthorized mod ification to th isdevice
could void the user’s authority to operate the
equipm ent.
Radar sensors
The radar sensors for BlindSpo t Assist are inte-
grated into the rear bumper. Make sure that the bumpers are free from dirt, ice or slush. The
sensors must not becovered, for example by
cyc le
r
acks or overhanging loads. Fol lowing a
severe impact or inthe event of damage to the
bumpers, have the function of the radar sensors
checked at a qualified specialist workshop.
Blin dSpo t Assist may no longer work properly.
Monitoring area
Inparticular, the detection of obstacles can be
impaired if:
Rthere is dirt on the sensors or anything else
covering the sensors
Rthere ispoor vis ibility, e.g. due to fog, heavy
rain, snow or spray
Rthere are narrow vehicles, e.g. motorcycles or
bic ycles
Rthe road has very widelanes
Rthe road has narrow lanes
Ryou are not driving inthe middle of the lane
Rthere are barriers or other road boundaries
Vehicles inthe monitoring range are then not
indicated.
At a distance of around 1.6 ft (0.5m); from the
vehicle, Blind Spot Assist monitors the area up
to 10 ft (3 m)next to =and behind :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 driving at the inner
edge of their lanes.
Due to the nature of the system:
Rwarnings may be issued in error when driving
close to crash barriers or similar solid lane
borders
Rwarnings may be interrupted when driving
alongside long vehicles, such as trucks, for a
prolonged time

WhenStandardis selected, no warning vibra-
tion occurs if:
Ryou switch on the turn signals. In this event,
the warnings are suppressed for a certain
period of time.
Ra driving safety system intervenes, e.g. ABS,
BAS or ESP®.
Adaptive
When Adaptive
is selected, no warning vibra-
tion occurs if:
Ryou switch on the turn signals. In this event,
the warnings are suppressed for a certain
period of time.
Ra driving safety system intervenes, e.g. ABS,
BAS or ESP®.
Ryou accelerate hard, e.g. kickdown.
Ryou brake hard.
Ryou steer actively, e.g. swerve to avoid an
obstacle or change lanes quickly.
Ryou cut the corner on a sharp bend.
In order that you are warned only when neces-
sary and in good time if you cross the lane mark-
ing, the system recognizes certain conditions
and warns you accordingly.
The warning vibration occurs earlier if:
Ryou approach the outer lane marking on a
bend.
Rthe road has very wide lanes, e.g. a highway.
Rthe system detects solid lane markings.
The warning vibration occurs later if:
Rthe road has narrow lanes.
Ryou cut the corner on a bend.
Driving Assistance PLUS package
General notes
The Driving Assistance PLUS package consists
of DISTRONIC PLUS (Ypage 164), Active Blind
Spot Assist (Ypage 197) and Active Lane Keep-
ing Assist (Ypage 200).
Active Blind Spot Assist
General notes
Active Blind Spot Assist uses a radar sensor
system, pointed toward the rear of the vehicle,
to monitor the area to the sides of the vehicle
which the driver is unable to see. A warning lamp lights up in the exterior mirrors and draws your
attention to vehicles detected in the monitored
area. If you then switch on the corresponding
turn signal to change lane, you will also receive
an optical and audible warning. If a risk of lateral
collision is detected, corrective braking may
help you avoid a collision. Before a course-cor-
recting brake application, Active Blind Spot
Assist evaluates the space in the direction of
travel and at the sides of the vehicle. For this,
Active Blind Spot Assist uses the forward-facing
radar sensors.
Active Blind Spot Assist supports you from a
speed of approximately 20 mph (30 km/h).
Important safety notes
Active Blind Spot Assist is only an aid and is not
a substitute for attentive driving.
GWARNING
Active Blind Spot Assist does not react to:
Rvehicles overtaken too closely on the side,
placing them in the blind spot area
Rvehicles which approach with a large speed
differential and overtake your vehicle
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 observe the traffic conditions care-
fully, and maintain a safe lateral distance.

Monitoring area
GWARNIN G
Active Blind Spot Assist does no tdetec tall
traffic situation sand road users. There is a
ris kof an accident.
Always mak esur ethat there is sufficien tdis-
tance on th eside for other traffic or obstacles.
At adistanc eof approximately 1. 6ft (0. 5m) ;
from the vehicle, Active Blind Spot Assist mon-
itors the area up to 10 ft (3 m) next to =and
behind :your vehicle, as shown in the picture. The detection of obstacles can be impaired in
the case of:
Rthere is dirt on the sensors or anything else
covering the sensors
Rpoor 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 inner edge of
your lane.
Due to the nature of the system:
Rwarnings may be issued in error when driving
close to crash barriers or similar solid lane
borders.
Rwarnings may be interrupted when you are
driving alongside particularly long vehicles,
such as trucks, for a prolonged time.
Warning lamp
:Warning lamp
Active Blind Spot Assist is not operational at
speeds below approximately 20 mph (30 km/h).
Vehicles in the monitoring range are then not
indicated.
If a vehicle is detected within the blind spot
monitoring range at speeds above 20 mph
(30 km/h), warning lamp :on the correspond-
ing side lights up red. This warning is always
emitted 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
7 mph (12 km/h).
