Traffic sign detection
Fig. 196: Windshield camera A
Traffic sign detection uses the camera A to detect
speed limits as well as the start and end points of
no-overtaking zones and bend ahead signs. Traffic
signs are evaluated together with the navigation
system’s map data and shown on the instrument
cluster.
If a speed limit is restricted to wet conditions, a
turn-off lane or a particular time, the additional sign
recognized will be compared with the information
provided by the vehicle (e.g. rain sensor, naviga-
tion 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.
WARNING
Lack of attention
The driver remains responsible when driving, e.g.
driving at an appropriate speed, regardless of
traffic sign detection. The system does not replace
the driver's attentiveness.
Traffic sign detection provides no warning when
speeds are exceeded, nor does it adjust the
vehicle speed to preset speed limits.
e
Particular attentiveness is required while
driving.
e
Always pay attention to the traffic conditions
and the vehicle surroundings.
e
Adjust the 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 water
spray and backlight). Sometimes the camera can-
not detect traffic signs or cannot detect them cor-
rectly. When this happens, no speed limit or bend
ahead warning or an incorrect speed limit or bend
ahead warning is displayed. Mounted traffic signs
always take priority over the traffic sign detection
in the instrument cluster.
e
Always pay attention to the road signs.
e
Particular attentiveness is required while
driving.
e
Always keep your eyes on the road ahead.
Information
Traffic sign detection is available in limited form in
the following situations for example:
– Camera heavily soiled, iced-up or covered (e.g.
stickers)
– In 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 at the interior
mirror (Fig. 196) with objects (e.g. stickers).
– The camera must always be kept free of dirt,
ice and snow.

Please see chapter "Car Care" on page 72.
Information
If the camera does not detect a traffic sign, the
speed limit stored in the navigation system will be
automatically displayed.
