R dirt on the sensors or anything else
covering the sensors
R poor visibility, e.g. due to fog, heavy rain,
snow or spray
R narrow vehicles, e.g. motorcycles or
bicycles
R the road has very wide lanes
R the road has narrow lanes
R you are not driving in the middle of the lane
R there are barriers or similarl ane borders
Vehicle sinthemonitorin grang eare then not
indicated. Blin
dSpotA ssist monitors the area up to
10 ft (3 m) behind your vehicle and directly
next to your vehicle, as shown in the diagram. 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
driving 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:
R
warnings may be issued in error when
driving close to crash barriers or similar
solid lane borders.
R the warning is canceled when driving for an
extended period next to long vehicles, such
as trucks.
The two radar 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 in the vicinity of the sensors.
The sensors must not be covered, for
example by cycle racks or overhanging loads.
Following asevere impact or in the event of
damage to the bumpers, have the function of
the sensors checked at aqualified specialist

Active Blind Spot Assist Genera
lnotes
Active Blind Spot Assis tuses aradar 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 displayint he exterior mirrors 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 arisk of lateral collision is
detected, corrective braking may help you
avoid acollision. Before acourse-correcting
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 radar sensors which
are pointed in the direction of travel.
Active Blind Spot Assist supports you from a
speed of approximately 20 mph (30 km/h).
For Active Blind Spot Assist to assist you
when driving, the radar sensor system must
be:
R activated(Y page 232)
R operational
Important safety notes
Active Blind Spot Assist is only an aid and is
not asubstitute for attentive driving. G
WARNING

R vehicles overtaken too closely on the side,
placing them in the blind spot area
R vehicles which approach with alarge speed
differential and overtak eyour vehicle As
aresult, Active Blind Spot Assist may
neither give warnings nor intervene in such
situations. There is arisk of an accident.
Always observe the traffic conditions
carefully, and maintain asafe lateral distance.

Monitoring area 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
distance on the side for other traffic or
obstacles. Active Blind Spot Assist monitors the area up
to 10 ft (3.0 m) behind your vehicle and
directly next to your vehicle, as shown in the
diagram.
The detection of obstacles can be impaired in
the case of:
R dirt on the sensors or anything else
covering the sensors
R poor visibility, e.g. due to rain, snow or
spray
Vehicles in the monitoring range are then not
indicated or indicated with adelay.
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 driving 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:
R warnings may be issued in error when
