Tra c 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 freeway access or exit road for example, or a er
you turn at an intersection, the display in the driv-
er's display can thus be updated without a tra c
sign having been detected.
Depending on vehicle equipment and country, the
system can also display speed restrictions up to
550 yds (500 m) ahead in the driver's display and
in the head-up display. The driver's display can
also show the distance to an upcoming lower limit
speed. For this purpose, information from the digi-
tal road map of the navigation system is used. The
Assistance
menu can also display a dynamic visu-
alization of the speed limits ahead.
If Tra c 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:
Tra c Sign Assist is not available in all countries.

If the vehicle is in a country where Tra c Sign
Assist is not supported, this is displayed continu-
ously.

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 tra c sign
ashes three times in the driver's display) or vis-
ual and acoustic, including a warning tone.
