The units for the speed limits (mph or
km/h) depend on the country you are
driving in.
It should be taken into account so that
you observe the speed limit.
For the system to operate correctly
when you change country, the units for
speed in the instrument panel must be
those for the country you are driving in.
The automatic reading of road signs is a
driving assistance system and does not
always display speed limits correctly.
The speed limit signs present on the
road always take priority over the
display by the system.
The system cannot in any
circumstances replace the need for
vigilance on the part of the driver.
The driver must observe the driving
regulations and must adapt the speed
of the vehicle to suit the weather and
traffic.
It is possible for the system to not
display the speed limit if it does not
detect a speed limit sign within a preset
period.
The system is designed to detect signs
that conform to the Vienna Convention
on road signs.
To maintain correct operation of the
system: regularly clean the area in front
of the camera.
Speed limit recognition
This system allows the speed limit detected by
the camera to be displayed in the instrument
panel.
Specific speed limits, such as those for heavy
goods vehicles, are not displayed.
The display of the speed limit in the instrument
panel is updated as you pass a speed limit sign
intended for cars (light vehicles).
Principles
Using a camera at the top of the windscreen,
this system detects and reads speed limit and
end of speed limit signs.
The system also takes account of information
on speed limits from the navigation system
mapping.
It is necessary to update your
navigation mapping regularly in order to
receive accurate information on speed
limits from the system.
