 Important notesIn chapter “Telephone”, you will find de-
tailed information regarding the telepho-
ne*, including emergency call.
1 Observe all legal requirementsWarning
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 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.

71 Telephone*
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
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. 
iIn 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 
phone book.
