Traffic sign recognition assists you when driving
by displaying detected speed limits or signs pro­
hibiting passing in the instrument cluster display
¢ fig. 104. Within the limits of the system, the
legal speed limits in schoo l zones are detected
and displayed .
General information
Traffic sign recognition can detect standard
speed limit signs that are within the camera's vis­
u al field. With assistance from navigation data,
detected speed limits are evaluated and shown in
the d isplay. The traffic s ign for the current de­
tected speed lim it will blink in the display if you
exceed the warning threshold set in the Infota in­
ment system
¢ page 1 OS.
Th e traffic sign recognition is subject to certa in
system limitat ions and may be unava ilable or on­
l y part ially ava ilab le in the follow ing s ituations:
- when visibility is poor, such as in snow, rain,
fog or heavy spray
- when there is glare, for example from oncom­
ing traffic or the sun
- at high speeds
- if the camera's visual
field¢ fig. 105 is covered,
for examp le by dirt or stickers. For information
on cleaning,
see¢ page 354
- if the traffic signs are completely or partially
covered, for examp le by trees, snow, dirt or
other vehicles
- if speed traffic signs do not conform to the
standards
- if traffic signs are damaged or bent
- if traffic signs are displayed on sign holders
with electronic signs
- if the traffic signs o r the config uration of the
road have changed (navigation data is no lon­
ger up-to-date)
_& WARNING
Pay attention to traffic and the area around
your vehicle when traff ic sign recogn ition is
turned on . The traffic s igns installed on the
