Traffic sign recognition
1
WARNING
Lack of attention
Responsibility while driving, e.g. choosing an appro-
priate speed, remains with the driver even when us-
ing traffic sign recognition. The system does not
replace the driver's attentiveness.
Traffic sign recognition does not adjust the speed of
the vehicle to specified speed limits.
e
Drive with extreme care.
e
Always check the traffic situation and the area
around the vehicle.
e
Adjust driving speed to road conditions.
WARNING
Failure of camera to de-
tect traffic signs
The camera’s view can be reduced by different in-
fluencing factors (e.g. rain, snow, ice, heavy spray
and oncoming headlights). In some circumstances,
the camera may not detect traffic signs or may de-
tect them incorrectly, which will result in a speed
limit or bend ahead warning not being displayed or
being displayed incorrectly. Traffic signs always take
precedence.
e Always pay attention to traffic signs.
e Drive with extreme care.
e Always keep your eyes on the road ahead.
Traffic sign detection detects speed restrictions, the
start and end of no overtaking zones and bend ahead
signs using camera A . The traffic signs are evaluated
in combination with the map data stored in the nav-
igation system and appear in the instrument cluster.
If a speed limit is restricted to a wet road, fog or a
certain time, the detected additional sign is com-
pared with the information provided by the vehicle
(e.g. rain sensor, navigation data and time).
The bend ahead warning is issued approx. 500 ft.
(150 m) before a bend that is significant for the
driver and continues until the relevant bend has been
passed.
Traffic sign detection is country-dependent and is
not available for all countries.
When driving in a country in which traffic sign de-
tection is not available, the driver is alerted to this
fact by a message on the instrument cluster.

Information
Traffic sign detection is available in restricted form
in the following situations, for example:
– Camera heavily soiled, iced-up or covered (e.g.
stickers).
– Unfavorable weather conditions (e.g. heavy rain)
– Traffic signs covered or damaged.
Information
To avoid impairing the detection performance of the
camera:
– Do not cover the camera area on the rearview
mirror A with objects (e.g. stickers).
– The camera must always be kept free of dirt, ice
and snow.
Information
If the camera does not detect a traffic sign, the
speed limit stored in the navigation system will be
automatically displayed.
