mation on telephone functions, emergency
call, and service numbers.
1 Observe all legal requirements.

Please read the “Telephone” chapter
before attempting to operate your tele-
phone.

Always drive with extreme caution
when you operate the hands-free tele-
phone.

For safety reasons, you should not use
the mobile telephone handset to make
a call while driving the vehicle.

If the signal strength is very weak (dis-
play in the symbol field of all menus),
wait until reception improves before
making a call.
WarningG
Some jurisdictions prohibit the driver from
using a cellular telephone while driving a ve-
hicle. Whether or not prohibited by law, for
safety reasons, the driver should not use the
cellular telephone while the vehicle is in mo-
tion. Stop the vehicle in a safe location be-
fore answering or placing a call.
If you nonetheless choose to use the cellular
phone while driving, please use the hands-
free device and be sure to pay attention to
the traffic situation at all times. Use the cel-
lular phone
1 only when road, weather and
traffic conditions permit.
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)
from inside the vehicle while the engine is
running. Doing so could lead to malfunction
of the vehicle’s electronic systems, possibly
resulting in an accident and/or personal in-
jury.
!
Radio transmitters, such as a portable
telephone or a citizens band unit,
should be used inside the vehicle only
if they are connected to a separate ex-
terior antenna that has been approved
by Mercedes-Benz.

Important notes
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.
