Display of traic signs
After checking and evaluating the information
from the camera, the infotainment system and
actual vehicle data, the system displays up to
two current road signs, and a generic addi-
tional sign
›››
Fig. 29:
•
First
: The sign that is currently valid for the
driver is displayed on the left hand side of the
screen, e.g. a prohibition of driving at over 130
km/h (80 mph).
•
Second: Another traic sign, such as a warn-
ing sign, can be displayed in second place.
•
Additional sign: If an additional sign is de-
tected, e.g. for temporary limits, it is shown be-
low the valid road sign. For system reasons, a
generic sign is displayed instead of the actual
detected sign. The valid road sign is displayed
on the Head-up-Display by the generic addi-
tional sign.
The warning sign display is not available in all
countries and the system may not be able to
detect all existing warning signs.
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 set or deactivated
completely in the menu
> Assistants >
Driver alerts > Road sign detection
››› page 36. The speed warning can be set to
a value of 0 km/h (0 mph), 5 km/h (3 mph) or
10 km/h (5 mph) above the permitted speed.
No entry sign
The traic 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.
Limited operation
The traic 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
traic or by the sun.
•
When driving at high speeds.
•
If the camera is covered or dirty.
•
If the traic signs are partially or totally ob-
structed, e.g. by trees, snow, dirt or other vehi-
cles.
•
In the case of traic signs that do not full
the regulations.
•
In the case of damaged or bent traic signs.
•
In the case of variable messages on over-
head or gantry signs (LED-based variable traic
signs or other lighting units).
•
If the maps on the navigation system are not
up-to-date.
•
In the case of adhesives aixed to vehicles
that depict traic signs, e.g. speed limits on
lorries.
