Traffic Sign Assist also uses data from the digital
street map in the navigation system. When you
leave or enter a municipality or change roads, on
a motorway exit or slip road forexample, or after
you turn at a junction, the display in the driver's
display can thus be updated without a traffic sign
having been detected.
If Traffic Sign Assist cannot determine the cur-
rently applicable maximum permissible speed
(e.g. due to missing signs), the following display
appears in the driver's display:
Traffic Sign Assist is not available in all countries.
If the vehicle is in a country where Traffic Sign
Assist is not supported, this is displayed continu-
ously.

Warning when the maximum permissible speed is
exceeded
The system can warn you if you unintentionally
exceed the maximum permissible speed. To do
this, you can specify in the multimedia system by
how much the maximum permissible speed can
be exceeded before a warning is issued. You can
set the warning to visual only (the traffic sign
flashes three times in the driver's display) or vis-
ual and acoustic, including a warning tone.
Additional functions of Traffic Sign Assist (coun-
try-specific)
Warning for no-entry signs: Traffic Sign Assist can
warn you if you drive the wrong way down a sec-
tion of road, forexample on motorway slip roads
or one-way streets.
Warning at pedestrian crossings: if you approach
pedestrian crossings, provided that pedestrians
are in the danger zone or are moving towards it,
Traffic Sign Assist can warn you up to a speed of
approximately 70 km/h.
Warning at stop signs: Traffic Sign Assist can warn
you up to a speed of approximately 70 km/h if
page 388).

you are about to drive past a stop sign uninten-
tionally. For this to be possible, the signs must be
clear, forexample if the system detects more than
one stop sign, or a stop sign can be confirmed
using the digital navigation map. No warning can
be issued if several different signs are detected.
Warning at red lights: Traffic Sign Assist can warn
you up to a speed of approximately 70 km/h if
you are about to drive through a red light uninten-
tionally.
The following conditions must be fulfilled:
Several traffic lights have been detected.
