89 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

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.

Please read the chapter “Telephone”
first before attempting to operate your
telephone.

Please also read the important notes in
the telephone and Voice control sys-
tem* operating manuals.

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 bar of all menus):
Wait until reception improves before
making a call.

Close the windows and reduce all out-
side noise as much as possible when
you use hands-free operation.

Also make sure that the air vents are
not pointed in the direction of the
microphones located in the overhead
control panel near the rear view mirror.
Adjust air vents and/or reduce blower
speed if necessary.

can occur when the network switches
areas. The phone will automatically try
to sign on to a network again.
