Tips  
Situation symbols  
The functions depend on the navigation da-  
ta* being up-to-date and correct identifica-  
tion by the traffic sign recognition*.  
The system only detects traffic signs that  
specify a speed limit.  
Depending on the equipment version, efficiency  
assist can use the following symbols to indicate  
the situation to which the system is responding.  
Depending on the equipment version, some of  
the symbols can only be displayed in the Driver  
assistance display to clarify to which situation  
the system is responding.  
The display in the instrument cluster is  
based on the units of measurement used for  
speed in the country where the vehicle is be-  
ing operated. As a result, a display of 50 in  
the instrument cluster can mean either mph  
or km/h, depending on the country.  
Aside from the road network, which is re-  
corded in the navigation system’s map infor-  
mation, certain functions may not be availa-  
ble.  
Some symbols only appear if Predictive messag-  
es are turned on, and some symbols only appear  
if Predictive control is turned on and Audi adap-  
tive cruise control* is actively regulating the vehi-  
cle.
