Important notes

Please read chapter “Telephone*” be-

phone.

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

For safety reasons, the mobile tele-
phone handset should not be used to
place or receive a call while driving.

If the signal is very weak (display in the
status bar):
Wait until reception improves before
placing a call.

Close the windows and reduce all ex-
ternal noise as much as possible when
using hands-free operation.

eration of the telephone using the
COMAND control unit and the multi-

wise specified, the descriptions and
the illustrated displays refer to the
COMAND control unit.

should only be used inside the vehicle if
they are connected to a separate exte-
rior antenna approved by Mercedes-
