Traffic sign detection system*
1)
Intr
oduction
The traffic sign detection system records the
stand
ard traffic signs in front of the vehicle
with a camera located on the base of the in-
terior mirror and provides information about
speed limits and overtaking prohibitions.
Within its limitations, the system also dis-
plays additional signals, such as time-specif-
ic prohibitions, signs for vehicles towing trail-
ers
›››
page 273 or limitations that only apply
in the event of rain. Even on journeys without
signs, the system may display any applicable
speed limits.
In Germany, on motorways and vehicle roads,
besides speed limits and overtaking provi-
sions the system also displays the end of
prohibition signs. The valid speed limit at the
time in other countries is always shown.
WARNING
The technology in the traffic sign detection
syst
em cannot change the limits imposed by
the laws of physics and only works within the
system's limits. Do not let the extra conven-
ience afforded by the traffic sign detection
system tempt you into taking any risks when
driving. The system is not a replacement for
driver awareness.
●
Adapt
your speed and driving style to suit
visibility, weather, road and traffic condi-
tions.
●
Poor visibility, darkness, snow, rain and fog
may lead to the system failing to display traf-
fic signs or not displaying them correctly.
●
If the camera's field of vision is dirty, cov-
ered or damaged, system operation may be
impaired.
WARNING
The driving recommendations and traffic indi-
c
ations
shown on the traffic sign detection
system may differ from the actual current
traffic situation.
●
The system may not detect or correctly
show all the traffic signs.
●
Traffic signs and traffic regulations have
priority over the recommendations and dis-
plays provided by the system.
Note
In order not to compromise the system's op-
eration, pl
ease take the following points into
account:
●
Regularly clean the area of vision of the
camera and keep it in a clean state, without
snow or ice.
●
Do not co
ver the field of vision of the cam-
era.
●
Always replace damaged or worn blades
when required to avoid lines on the camera's
field of vision.
●
Check that the windscreen is not damaged
in the area of the camera's field of vision.
Note
●
The u
se of out
dated maps on the naviga-
tion system may cause the system to show
traffic signs incorrectly.
●
In the waypoints mode of the navigation
system, the traffic sign detection system is
only partly available.
