ters at a time.
Speak each individual letter clearly.

Voice Control troubleshooting
ProblemPossible cause/consequenceSuggested solution
Voice Control System does not recognize
commands.You have not operated the system from the
driver’s seat.Operate the Voice Control System only
by the driver as the microphone is
geared to the driver side.
You have spoken unclearly, too loudly or
too quietly.Speak the commands in a continuous
manner using a normal tone.
A blower is set to the highest setting, vents
are pointed at microphones or wind noise is
being created through open windows.Avoid loud disturbances.
Voice Control System does not recognize a
address book entry.The voice entries in the address book sound
too similar.When you create your address book en-
tries, select names with the greatest
possible acoustic differences: If for ex-
ample you have the names Smith and
Schmidt, choose for example “Smith
work” or “Schmidt John”.
Speak the command “List phone book”.
The system reads out the address book
entry by entry.
Press! when the desired entry is
being read out.
The entry is selected and the corre-
sponding number is dialed
(

Voice Control individualization
The individualization is used to adapt the
Voice Control System to your own voice
and to therefore improve speech recogni-
tion. This does not affect the speech rec-
ognition of other users.Individualization consists of two stages:
Digits
Commands
You can activate individualization in the
COMAND system settings (
page 229).
A dialog and screen displays will guide you
through the individualization process.
The system can be reset to the factory set-
tings at any time.
iThe individualization can only be performed
when the vehicle is stationary.
If you drive off, the individualization will be can-
celed.
After starting the session, the system will guide
you through the individualization by means of
acoustic instructions.iYou may wish to complete only a portion of
the individualization process.
Completing the digits portion alone may result in
an improved recognition rate.
Individualization can be exited at any time. The
data trained, however, will only be retained if a
given individualization portion is completed and
the data is stored when prompted to do so by the
system.
