Driver information
27
Instrument panel
The speed warning can be set or deacti-
v
ated completely in the menu
Driver
assistance > Road sign detection
›››page36. The speed w
arning can be set
to a value of 0, 5 or 10km/h (0, 3 or 5mph)
above the permitted speed.
Trailer mode
In vehicles equipped with a towing bracket de-
vice from the factory and a trailer that is electri-
cally connected to the vehicle, it is possible to
activate or deactivate the display of specific
trac signs for vehicles with trailer, such as
speed limits or overtaking prohibitions.
It can be activated or deactivated in the info-
tainment system using the function button
Driver assistance > Trailer assist
›››page36.
F
or trailer mode, the display of speed limits ap-
plicable to the type of trailer or to the legal pro-
visions can be adjusted. The speed is adjusted
in steps of 10km/h (5 mph) within the range
between 60 and 130 km/h (40 and 80mph). 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 80km/h
(50mph).
If the speed warning for the trailer is deactiva-
ted, the system displays the speed limits as if
there were no trailer hitched.
Limited operation
The tr
ac 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
trac or by the sun.
●
When driving at high speeds.
●
If the camera is covered or dirty.
●
If the trac signs are partially or totally ob-
structed, e.g. by trees, snow, dirt or other vehi-
cles.
●
In the case of trac signs that do not fulfil the
regulations.
●
In the case of damaged or bent trac signs.
●
In the case of variable messages on over-
head or gantry signs (LED-based variable traf-
fic signs or other lighting units).
●
If the maps on the navigation system are not
up-to-date.
●
In the case of adhesives axed to vehicles
that depict trac signs, e.g. speed limits on lor-
ries.
WARNING
The technology in the tr
ac sign detection
system cannot change the limits imposed by
the laws of physics and only works within the
system's limits. Do not let the extra conven-
ience aorded by the trac sign detection
system tempt you into taking any risks when
driving. The system is not a replacement for
driver awareness.
●
Adapt your speed and driving style to
suit visibility, weather, road and trac condi-
tions.
●
Poor visibility, darkness, snow, rain and fog
may lead to the system failing to display
trac 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 tr
ac in-
dications shown on the trac sign detection
system may dier from the actual current
trac situation.
●
The system may not detect or correctly
show all the trac signs.
●
Trac signs and trac regulations have
priority over the recommendations and dis-
plays provided by the system.
