ProblemPossible cause/consequenceSuggested solution
Voice Control System does not recognize a
station list entry.The voice entries for the station names
sound too similar.When you create your address book en-
tries, select names with the greatest
possible acoustic differences.
Speak the command “List station list”.
The system reads out the station list en-
try by entry.
Press ! when the desired station
name is being read out.
The station is selected (
page 311).
Should interference occur during the pro-
cess of storing a name, the Voice Control
System prompts you to repeat your voice
entry a third and fourth time. If the interfer-
ence continues, the dialog is stopped.Both voice entries differ.Pronounce the voice entries both times
in the same manner.

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
(
page 295).

330 Control systems
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 237).
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.

To prevent possible personal injury, always
keep hands and fingers away from the door
or trunk lid opening when closing a door or

SmartKey with KEYLESS-GO*
Vehicles equipped with KEYLESS-GO come
with two SmartKeys with KEYLESS-GO,
each with remote control and a removable
mechanical key.
The locking tabs for the mechanical key
portion of the two SmartKeys with
KEYLESS-GO are of different color to help
distinguish each SmartKey with
KEYLESS-GO unit.
The KEYLESS-GO function is integrated
into the SmartKey. On these vehicles, the
validity of the SmartKey with KEYLESS-GO
is checked every time you grasp an outside
door handle.
With the KEYLESS-GO function, you can
lock and unlock the vehicle without using
the remote control buttons on the
SmartKey and start the engine without in-
serting the SmartKey in the starter switch.The SmartKey with KEYLESS-GO centrally
locks and unlocks, when set to factory set-
tings (

SmartKey with KEYLESS-GO left in the vehi-
cle or with the KEYLESS-GO button on the
starter switch, or could release the electron-
ic parking brake, thereby putting them-
selves and others in danger. Switch off the
engine and take the SmartKey with
KEYLESS-GO with you even if you are only
leaving the vehicle for a short while.
