Driving and operating175In some cases, traffic sign assistant is
cleared up automatically by the
system.
Clearing of traffic signs
There are different scenarios that
lead to clearing the currently
displayed traffic signs. After clearing,
the “Default Sign” is displayed in the
Driver Information Centre.
Reasons for signs being cleared: ● A predefined distance was driven
or time has elapsed (differs for
each sign type)
● Vehicle drives through a turn
● The speed becomes slower than 32 mph (city entry detection)
Fault
The traffic sign assistant system may
not operate correctly if:
● The area of the windscreen, where the front camera is
located, is not clean or affected
by foreign items, e.g. stickers.
● Traffic signs are completely or partially covered or difficult to
discern.● There are adverse environmental
conditions, e.g. heavy rain, snow, direct sunlight or shadows.
● Traffic signs are incorrectly mounted or damaged.
● Traffic signs do not comply with the Vienna Convention on trafficsigns (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 performing these
actions, no warning will be issued.
