Possible cause/consequence
Suggested 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 284).
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
Problem
Possible cause/consequence
Suggested 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 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 268).

302 Control systemsVoice Control* individualizationThe 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 215).
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.
i
The 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.
i
You 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.

portion of the two SmartKeys are of differ-
ent color to help distinguish each
SmartKey unit.
The SmartKey provides an extended oper-
ating range. To prevent theft, however, it is
advisable to only unlock the vehicle when
you are in close proximity to it.

When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. It is possible

To prevent possible personal injury, always
keep hands and fingers away from the door
or trunk lid opening when closing a door or
the trunk. Be especially careful when small
children are around.
Before closing doors, make sure there is no

Warning!
G
When leaving the vehicle, always take the
SmartKey with KEYLESS-GO* with you and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. It is possible for children
to open a locked door from the inside, which
could result in an accident and/or serious
personal injury.
They could start the vehicle with a valid
SmartKey with KEYLESS-GO left in the vehi-
cle or with the KEYLESS-GO button on the
starter switch, or they could release the
electric parking brake, thereby putting
themselves 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.

Page 309 of 705
308 Controls in detailLocking and unlockingImportant notes on using KEYLESS-GO
You can also use the SmartKey with
KEYLESS-GO like a normal SmartKey
(page 304).
The starter switch is under the
KEYLESS-GO button. Pull the
KEYLESS-GO button out in order to ac-
cess the starter switch.
You can combine KEYLESS-GO func-
tions with normal SmartKey functions
(e.g. unlocking with KEYLESS-GO and
locking with button ‹).
Always carry the SmartKey with
KEYLESS-GO with you.
Never store the SmartKey with
KEYLESS-GO together with:
Electronic items such as a mobile
phone or another SmartKey with
KEYLESS-GO
Metallic objects such as coins or
metal foil
Doing so could impair the function of
the KEYLESS-GO system.
To lock or unlock the vehicle, the
SmartKey with KEYLESS-GO must be
located outside the vehicle within ap-
proximately 3 ft. (1 m) of a door or the
trunk lid.
In order to start the engine with the
SmartKey with KEYLESS-GO:
The SmartKey with KEYLESS-GO
must be located in the vehicle.
The brake pedal must be firmly de-
pressed. Do not depress the accel-
erator.
If the SmartKey with KEYLESS-GO is
positioned farther away from the vehi-
cle, the system may no longer recog-
nize the SmartKey with KEYLESS-GO.
The vehicle then cannot be locked or
the engine started via the KEYLESS-GO
system.
If the SmartKey with KEYLESS-GO is re-
moved from the vehicle (e.g. if passen-
ger exits the vehicle with the SmartKey
with KEYLESS-GO)
when pressing the KEYLESS-GO
start/stop button or trying to lock
the vehicle with the outside door
handle the message “Key not recog-
nized” appears in the multifunction
display
with the engine running, the mes-
sage “Key not recognized” appears
in the multifunction display while
driving off.
Find the SmartKey or change its
present location immediately
(e.g. place it on the front passenger
seat or insert it in shirt pocket).
If you have started the engine with the
KEYLESS-GO start/stop button
(page 317), you can turn it off again
with:
the KEYLESS-GO start/stop button
the SmartKey inserted in the starter
switch, when the automatic trans-
mission is in positionP
