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).

field of vision.
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.

If the traffic signs are partially or totally
covered, e.g. by trees, snow, dirt or other ve-

In the case of traffic signs that do not fulfil
the regulations.
A sign valid only with restrictions, e.g. no
overtaking at certain times, may be dis-
played.
●
In the case of damaged or bent traffic
signs.
If the speed warning for the trailer is deacti-
vated, the system displays the speed limits as
if there were no trailer hitched.

In the case of variable messages on over-
head or gantry signs (LED-based variable
traffic signs or other lighting units).
Speed warning (depending on the instru-
ment panel)
No entry sign

The traffic sign recognition system warns
acoustically and visually in the instrument
panel when a no entry sign is crossed on a
one-way road or an entrance to a motorway
or highway.
If the maps on the navigation system are
not up-to-date.
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.
