traffic situation. DVD maps do not cover all
areas nor all routes within an area. For
example, if the traffic routing has been
changed or the direction of a one-way road
has been reversed.
For this reason, you must always observe
applicable road and traffic rules and
regulations during your journey. Road and
traffic rules and regulations always have
priority over the navigation commands
generated by the system.

Warning!
Navigation announcements are intended to
direct you while driving without diverting
your attention from the road and driving.
Please always use this feature instead of
consulting the map display for directions.
Consulting the symbols or map display for
directions may cause you to divert your
attention from driving and increase your
risk of an accident.
Map software
The digital maps generated by the map
software become outdated in the same way
as conventional road maps. Optimum route
guidance can only be provided by the
navigation system in conjunction with the
most up-to-date map software. Information
about new map software versions can be
obtained from an authorized Mercedes-Benz
Center.
Updating the map software
You can update the map software yourself
using a DVD.

The updating process can take between
10 and 60 minutes, depending on the size
of the map software. If the radio was
switched on before you started the
updating process, you can still adjust the
volume. You can also use COMAND to
operate the automatic air conditioning and

not operational. If possible, carry out the
update when the vehicle is stationary.

switched off and the vehicle battery has
insufficient power, COMAND may

in order to protect the battery. If this
