Important notesIn chapter “Telephone”, you will find de-
tailed information regarding the telephone,
including emergency call, SMS function
and service numbers.
1 Observe all legal requirements
Please read the chapter “Telephone”
first before attempting to operate your
telephone.

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

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)
you should not make telephone calls.
Wait until reception improves.
Warning
G
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.
without beeing connected to an external an-
tenna) from inside the vehicle while the en-
gine is running. Doing so could lead to
malfunction of the vehicle’s electronic sys-
tems, possibly resulting in an accident and
personal injury.
!Radio transmitters, such as a portable
telephone or a citizens band unit
should only be used inside the vehicle
if they are connected to a separate ex-
terior antenna that has been approved
by Mercedes-Benz.

is not or not yet registered in the net-
work.

The above message also appears 
if the network is no longer available
due to weak signals

appears for 8 seconds)

vated. Please wait.” appears.
