G
Some jurisdictions prohibit the driver from
using a mobile phone while driving a vehicle.
Whether or not prohibited by law, for safety
reasons, the driver should not use the mobi-
le phone while the vehicle is in motion. Stop
the vehicle in a safe location before answe-
ring or placing a call.
If you nonetheless choose to use the mobile
phone while driving, please use the hands-
free device and be sure to pay attention to
the traffic situation at all times. Use the mo-
bile 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 being 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.

Important notes
iIf you have a Mercedes-Benz specified
integrated mobile telephone (TDMA/
CDMA or GSM) and the telephone is
inserted in the cradle, the telephone
functions can be used as follows: 
at the COMAND

at the multifunction steering wheel

with the Voice control system*
This instruction manual describes the
operation at the COMAND. Unless
otherwise indicated, the descriptions
and illustrations refer to the COMAND.
Operation at the mobile phone and
operation with the Voice control
system* are described in separate
operating guides. Refer to the vehicle
Operator’s Manual for operation of the
telephone using the multifunction
steering wheel.
Which soft key functions are available
depends on the mobile phone variant.
iThe COMAND can display phone
number and name of the other party
(e.g. if the COMAND detects an
incoming call, but also in other menus).
For the number to be displayed, the
number information must be
transmitted with the incoming call. The
same goes for the name display which
additionally requires that the caller’s
number and name are saved in the
phone book.
iNo ring or DTMF tones will be heard
when a phone set to silent mode is in-
serted into the cradle.
For ringtone settings, refer to the sepa-
rate operating instructions for the
mobile phone.
