1 Observe all legal requirements
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.
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.
WarningG
Radio transmitters, such as a portable tele-
phone or a citizens band unit should only be
used inside the vehicle if they are connected
to a separate exterior antenna that has been
approved by Mercedes-Benz.

inserted in the cradle, the telephone
functions can be used as follows:

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 is
described in separate operating guides.
Refer to the vehicle Operator’s Manual
for operation of the telephone using the
multifunction steering wheel.

In certain menus, the COMAND can
display date and time of the calls.
The 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
