Blind Spot Assist
General notes
Blind Spot Assist monitors the areas on either
side of the vehicle that are not visible to the
driver with two lateral, rear-facing radar sen-
sors. A warning display in the exterior mirrors
draws your attention to vehicles detected in
the monitored area. If you then switch on the corresponding turn signal to change lanes,
you will also receive a visual and audible col-
lision warning.
Blind Spot Assist supports you from a speed
of approximately 30 km/h.
Important safety notes G
WARNING
Blind Spot Assist does not react to vehicles:
R overtaken too closely on the side, placing
them in the blind spot area
R when the difference in the speed of
approach and overtaking is too great
As a result, Blind Spot Assist cannot warn
drivers in these situations. There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and maintain a safe distance at the side
of the vehicle.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitute for
attentive driving. Always ensure that there is
sufficient distance to the side for other road
users and obstacles.
Radar sensors
The radar sensors for Blind Spot Assist are
integrated 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 spe-
cialist 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 a narrow vehicle travelling in front, e.g. a
motorcycle or a bicycle
R very wide lanes
R narrow lanes
R vehicles not driving in the middle of their
lane
R barriers or other road boundaries
Vehicles in the monitoring range are then not
indicated. Blind Spot Assist monitors the area up to
3.0 mbehind your vehicle and directly next to
your vehicle, as shown in the diagram. For this
purpose, Blind Spot Assist uses radar sensors in the rear bumper.
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 the vehicles are driving on the inner
side of their lane. Driving systems
