Traffic Sign Assist
Function of Traffic Sign Assist
Traffic Sign Assist detects traffic signs with mul-
tifunction camera
:
and assists you by dis-
playing detected speed limits and overtaking
restrictions in the instrument cluster. The cam-
era also detects traffic signs with a restriction
indicated by an additional sign (e.g. in wet con-
ditions).
System limitations
Traffic Sign Assist is only an aid and is not always
able to correctly display speed limits and over-
taking restrictions. The actual traffic signs
always have priority over the Traffic Sign Assist
display.
The system may be impaired or may inoperative
in the following situations:
R
if there is poor visibility, e.g. due to insuffi-
cient illumination of the road, if there are
highly variable shade conditions or in rain,
snow, fog or spray
R
if there is glare, e.g. from oncoming traffic,
direct sunlight or reflections
R
if the windscreen in the area of the multifunc-
tion camera is dirty, or if the camera is misted
up, damaged or covered
R
if the traffic signs are hard to detect, e.g. due
to dirt or snow, or because they are covered
or because of insufficient lighting
R
if the information in the navigation system's
digital map is incorrect or out-of-date
R
if the signs are ambiguous, e.g. traffic signs on
construction sites or in adjacent lanes
