228Driving and operatingClearing of traffic signs
There are different scenarios that
lead to clearing the currently
displayed traffic signs. After clearing,
the “Default Sign” or a sign from
navigation map data 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
● If no navigation map data is available and speed drops below52 km/h (city entry detection)
● If navigation map data is available and a city entry/exit was
detected due to map data change
Traffic sign detection in
conjunction with navigation
system
If the vehicle is equipped with a
navigation system, the currently
displayed sign can either originate
from optical sign detection or from the
map data.If the currently displayed sign
originates from map data and the map
information changes, a new sign will
be displayed. This may lead to
detection of a new sign although no
sign on the road may have been
passed.
System limitations Traffic sign assistant may not operate properly when:
● Vehicle speed is faster than 200 km/h.
● Driving on winding or hilly roads. ● During nighttime driving.
● Weather limits visibility, such as fog, rain, or snow.
● The sensor in the windscreen is blocked by snow, ice, slush, mud,dirt, windscreen damage or
affected by foreign items, e.g.
stickers.
● The sun is shining directly into the camera lens.
● Traffic signs are completely or partially covered or difficult to
discern.● Traffic signs are incorrectly mounted or damaged.
● Traffic signs do not comply with the Vienna Convention on Road
Signs and Signals (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.

230Driving and operatingThe system is only operable when a
lane marking is detected.
If the system only detects lane
markings on one side of the road, it
will only assist for this side.

Driver Information Centre pops-up
and a chime sounds as long as lane
keep assist detects hands-free
driving.
Deactivation The system is deactivated by
pressing a; the LED in the button
extinguishes.
The system is deactivated
automatically when a trailer is
detected.
System limitations
The system performance may not
operate properly when:
● Vehicle speed is out of range from 60 to 180 km/h.
● Driving on winding or hilly roads.
● During nighttime driving.● Weather limits visibility, such as fog, rain, or snow.
● The sensor in the windscreen is blocked by snow, ice, slush, mud,dirt, windscreen damage or
affected by foreign items, e.g.
stickers.
● The sun is shining directly into the camera lens.
● Close vehicles ahead
● Banked roads
● Road edges
● Roads with poor lane markings
● Sudden lighting changes
● Vehicle modifications, e.g. tyres.
Switch off the system if the system is
disturbed by tar marks, shadows,
road cracks, temporary or
construction lane markings, or other
road imperfections.9 Warning
Always keep your attention on the
road and maintain proper vehicle
position within the lane, otherwise
vehicle damage, injury or death
could occur.
Lane keep assist does not
continuously steer the vehicle.
The system may not keep the
vehicle in the lane or give an alert,
even if a lane marking is detected.
The steering of the lane keep
assist may not be sufficient to
avoid a lane departure.
