Displ
ay of tr
affic signs
When the tr
affic sign det
ection system is con-
nected, a camera located on the base of the
interior rear-view mirror records the traffic
signs in front of the vehicle. After checking
and evaluating the information from the cam-
era, the navigation system and the current
vehicle data, up to three valid road signs are
displayed,
›››
Fig. 74 with their additional
signs.
●
First: The sign that is currently valid for the
driver is shown in the left side of the screen
For example, a maximum speed limit of
130 km/h (100 mph)
›››
Fig. 74 .
●
Second: A sign valid only in certain circum-
stances, e.g. 100 km/h (60 mph) is shown sec-
ond, together with the additional rain sign.
●
Additional sign: If the windscreen wiper is
working while you are driving, the signal with
the additional rain sign will be shown first, on
the left, as it is the one that is applicable at
the time.
●
Third: A sign valid only with restrictions, e.g.
No overtaking at certain times, will be dis-
played in third place

Speed warning
If the system detects that the permitted
speed is exceeded, it may warn the driver
with a “gong” and visually with a message on
the dash panel display.
The speed warning can be adjusted or deac-
tivated completely in the infotainment system
using the > SETTINGS > Driver assis-
tance
›››
page 89 button. The speed is ad-
justed in steps of 5 km/h (3 mph) within a
range of between 0 km/h (mph) and 20 km/h
(12 mph) above the maximum speed permit-
ted.
Trailer mode
In vehicles equipped with a towing bracket
device from the factory and a trailer that is
electrically connected to the vehicle, it is
possible to activate or deactivate the display
of specific traffic signs for vehicles with trailer,
such as speed limits or overtaking prohibi-
tions. Activation or deactivation is performed
in the infotainment system using the >
SETTINGS > Driver assistance
›››
page 89 buttons.
For trailer mode, the display of speed limits
applicable to the type of trailer or to the legal
provisions can be adjusted. The speed is ad-
justed in steps of 10 km/h (5 mph) within a
range of between 60 km/h (40 mph) and
130 km/h (80 mph). If it is adjusted to a speed
greater than that which is permitted in the
country in question for driving with a trailer,
the system automatically displays the usual
speed limits, e.g. in Germany 80 km/h
(50 mph).
If the speed warning for the trailer is deacti-
vated, the system displays the speed limits as
if there were no trailer hitched.
Limited operation
The traffic sign detection system has certain
limitations. The following cases may lead the
system to operate with limitations or not at
all:
●
In the case of poor visibility, e.g. in snow,
rain, fog or intense mist.
●
In cases of dazzling, e.g. caused by head-
on traffic or by the sun.
●
When driving at high speeds.
●
If the camera is covered or dirty.
●
If the traffic signs are out of the camera's
field of vision.
●
If the traffic signs are partially or totally
covered, e.g. by trees, snow, dirt or other vehi-
cles.
●
In the case of traffic signs that do not fulfil
the regulations.
●
In the case of damaged or bent traffic
signs.
