page 88. The speed is ad-
justed in steps of 5 km/h (3 mph) within a
range of between 0 km/h (mph) and 10 km/h
(6 mph) above the maximum permitted
speed.
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. It can be activated or deactivated in the
infotainment system using the function button

page 88.
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.
●
In the case of variable messages on over-
head or gantry signs (LED-based variable
traffic signs or other lighting units).
●
If the maps on the navigation system are
not up-to-date.
●
In the case of adhesives affixed to vehicles
that depict traffic signs, e.g. speed limits on
lorries.
WARNING
The technology in the traffic sign detection
syst
em cannot change the limits imposed
by the laws of physics and only works with-
in the system's limits. Do not let the extra
convenience afforded by the traffic sign
detection system tempt you into taking any
risks when driving. The system is not a re-
placement for driver awareness.
●
Adapt your speed and driving style to suit
visibility, weather, road and traffic condi-
tions.
●
Poor visibility, darkness, snow, rain and
fog may lead to the system failing to dis-
play traffic signs or not displaying them
correctly.
●
If the camera's field of vision is dirty, cov-
ered or damaged, system operation may
be impaired.
WARNING
The driving recommendations and traffic
indications sho
wn on the traffic sign detec-
tion system may differ from the actual cur-
rent traffic situation.
●
The system may not detect or correctly
show all the traffic signs.
●
Traffic signs and traffic regulations have
priority over the recommendations and dis-
plays provided by the system.
