No entry (wrong-way warning)
A warning message : is displayed in the
instrument cluster if Traffic Sign Assist
detects that you are passing a "no entry" sign
and you are driving in the wrong direction.
You will then also hear a warning tone. You
should immediately check your direction of
travel in order to avoid danger to yourself and
other road users.
Lane Tracking package
General notes
The Lane Tracking package consists of Blind
Spot Assist ( page 226) and Lane Keeping
Y
Assist ( page 228).
Y
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:
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
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:
dirt on the sensors or obscured sensors
R
poor visibility, e.g. due to fog, heavy rain or
R
snow
a narrow vehicle travelling in front, e.g. a
R
motorcycle or a bicycle
very wide lanes
R
narrow lanes
R
vehicles not driving in the middle of their
R
lane
barriers or other road boundaries
