Important notes
WarningG
For safety reasons, you should only enter a
destination when the vehicle is stationary.
When the vehicle is in motion, a passenger
should enter the destination. Study manual
and select route before driving.
Do not watch display screen or operate but-
tons while the vehicle is in motion- let voice
instructions guide you. Stop at a safe loca-
tion before using buttons or making correc-
tions.
Traffic regulations always have priority over
any route recommendations given.
The route calculated by the MCS is a
recommendation on how to best reach your
selected destination.
During route guidance, you will not receive
any information on
Traffic lights
Stop and yield signs
Parking or stopping zones
One-way streets
Narrow bridges
Similar traffic regulation data
You should therefore always strictly observe
traffic regulations while driving. Drive care-
fully and always obey traffic laws and road
signs even if they contradict the MCS
instructions.
WarningG
The DVD reader contains a Class 1 laser
product. There is a danger of invisible laser
radiation if the cover is opened or damaged.
Do not remove the cover. The DVD reader
does not contain any parts which can be ser-
viced by the user. For safety reasons, have
any service work which may be necessary
performed only by qualified personnel.
!
MCS calculates the route with the help
of data stored on the navigation DVD.
Only use Mercedes-Benz navigation
DVDs. Using other navigation DVDs
might lead to malfunctions.
Because of changes in local traffic pat-
terns (e.g. road work) and/or incom-
plete data, errors in calculation may
occur.
As a result, the recommended route
may deviate from the ideal route. The
data stored on the DVD only reflects lo-
cal conditions at the time of produc-
tion. DVD maps do not cover all areas
nor all routes within an area.
