Important notesWarning
G
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 locati-
on before using buttons or making correc-
tions.
Traffic regulations always have priority over
any route recommendations given.
The route calculated by COMAND is a re-
commendation on how the 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 COMAND in-
structions.

Warning
G
The CD reader contains a Class 1 laser pro-
duct. There is a danger of invisible laser ra-
diation if the cover is opened or damaged.
Do not remove the cover. The CD 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 an authorized
Mercedes-Benz Center.
!COMAND calculates the route with the
help of data that is stored on the navi-
gation CD.
Only use Mercedes-Benz navigation
CDs. Using other navigation CDs might
lead to malfunctions.
Because of changes in local traffic pat-
terns (e.g. road works) 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 CD only reflects lo-
cal conditions at the time of CD pro-
duction.
iThe CD drive can read navigation CDs
and playback audio CDs.
If an audio CD is in the CD drive and
b is pressed, the message “No CD
available. Insert NAVI-CD type DX only”
will be displayed.

Remove the audio CD and insert a
navigation CD (
page 119).

114 NavigationImportant notes
Travelling abroad
If you intend to travel through different re-
gions or abroad, you will need the respec-
tive navigation CD.
Contact your Mercedes-Benz Center or
the Client Assistance Center at
1-800-FOR-MERCedes (1-800-367-6372)
for available CDs.
Change the navigation CD
(page 119).
!GPS (G
lobal P
ositioning S
ystem) sig-
nals received make it possible to de-
termine the current vehicle position.
Deviations from the actual position
may occur


if the reception of GPS signals is
disturbed e.g. in parking garages
and tunnels


if road conditions are bad


depending on the vehicle’s conditi-
on
If the reception of the GPS signal is un-
available, you will have to manually en-
ter the current vehicle position
(page 180).
If your vehicle has been transported by
a car, train or ferry, COMAND needs
some time to find its exact position.
Moving the vehicle a few yards is typi-
cally enough to remedy this situation.
