Speed Limit Recognition  
and Recommendation  
Refer to the General recommendations on the  
use of driving and manoeuvring aids.  
The automatic reading of road signs is a  
driving aid 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 is designed to detect signs that  
conform to the Vienna Convention on road  
signs.  
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 when passing  
a speed limit sign intended for cars (light  
vehicles).

speed in the instrument panel, according to  
the speed limits in the country in which you are

mapping.
