Operation Manual

Driving and operating 143
Traffic sign detection in
conjunction with navigation
system
If the vehicle is equipped with
a navigation system, the following
features can be available:
■ recognition of city limits
■ constant indication of actual speed
limits
■ immediate indication of speed limits
after leaving main route
Fault
The traffic sign assistant system may
not operate correctly when:
■ the area of the windscreen, where
the front camera is located, is not
clean
■ traffic signs are completely or
partially covered or difficult to
discern
■ there are adverse environmental
conditions like heavy rain, snow,
direct sunlight or shadows. In this
case No Traffic Sign Detection due
to Weather is indicated on the
display
■ traffic signs are incorrectly mounted
or damaged
■ traffic signs do not comply with the
Vienna Convention on traffic signs
(Wiener Übereinkommen über
Straßenverkehrszeichen)
Caution
The system is intended to help the
driver within a defined speed
range to discern certain traffic
signs. Do not ignore traffic signs
which are not displayed by the
system.
The system does not discern any
other than the conventional traffic
signs that might give or end
a speed limit.
Do not let this special feature
tempt you into taking risks when
driving.
Always adapt speed to the road
conditions.
The driver assistance systems do
not relieve the driver from full
responsibility for vehicle
operation.
Lane departure warning
The lane departure warning system
observes the lane markings between
which the vehicle is driving via a front
camera. The system detects lane
changes and warns the driver in the
event of an unintended lane change
via visual and acoustic signals.
Criteria for the detection of an
unintended lane change are:
■ no operation of turn signals
■ no brake pedal operation
■ no active accelerator operation or
speeding-up
■ no active steering
If the driver is active, no warning will
be issued.
