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 cor-
responding turn signal to change lanes, you will
also receive a visual and audible collision warn-
ing.
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:
overtaken too closely on the side, placing
R
them in the blind spot area
when the difference in the speed of
R
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 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
In particular, the detection of obstacles can be
impaired in the case of:
dirt on the sensors or obscured sensors
R
poor visibility, e.g. due to fog, heavy rain,
R
snow or spray
narrow vehicles, e.g. motorcycles or bicycles
R
very wide lanes
R
narrow lanes
R
vehicles not driving in the middle of their lane
R
barriers or other road boundaries
R
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 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 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.
Due to the nature of the system:
warnings may be issued in error when driving
R
close to crash barriers or similar solid lane
borders
warnings may be interrupted when driving
R
alongside long vehicles, for example lorries,
for a prolonged time
