What to do if ...
Problem Possible cause/consequence Suggested solution
The Voice
Control
System does
not
recognize
commands. You have not operated the system
from the driver’s seat. X
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. X
Speak the commands in a
continuous manner

using a normal
tone. The blower could be set to the
highest setting, vents could be
pointing at microphones or wind
noise could be created due to open
windows. X
Avoid loud disturbances. An address
book entry
without
voice
name is not
recognized. The address book fields for first and
last name are completed. However,
you only spoke the last name or the
first name. X
Say both the first name and the
last name of the address book
entry. Pronunciation of names in the
address book does not differ
sufficiently or the spelling differs
from the pronunciation. X
Make sure the address book
entries are reasonable.
Check the

address book entries for
the following:
R Name entries such as first and
last name are in the correct field.
R Do not use abbreviations or
short forms, e.g. acronyms.
R Avoid unnecessary blanks
within the name
R Do not use special characters.
or
X Create a voice name
(Y page 227).
or
X Speak the command “Read out

Problem Possible cause/consequence Suggested solution
An address
book entry
with voice
name is not
recognized. The voice names do not differ from
each other sufficiently. X
Make voice names that differ as
much as possible. For example,
make the
names Wight and Wright
unique by entering them as “Mr
Wight office” and “Mr Wright
John”.
or
X Speak the command “Read out
address book”.
The Voice Control System reads
the address book aloud.
X Press button ? on the
multifunction steering

wheel when
the desired name is read. A station list
entry is not
recognized. The voice names of the station
names do not differ from each other
sufficiently. X
Create a voice name for the station
(Y page 233).
or
X Speak the command “Read out
station list”.
The Voice Control System reads
the station list aloud.
X Press button ? on the
multifunction steering

wheel when
the desired station name is read.
The station is selected
(Y page 233). The Voice
Control
System
prompts you
to repeat a
voice name
repeatedly
when saving. The way you have spoken the voice
name is different. X
Pronounce the voice name in the
same way during the entire
process. Voice Control System troubleshooting

Problem Possible cause/consequence Suggested solution
You want to
enter a city,
street or city
center but
you have to
spell the
entry. Entering part of an address has failed
after several attempts, e.g. due to
background noise, or you have tried
to enter an address in Puerto Rico
(Y page 220). X
Spell the entry. You have
entered a
phone
number as a
string
but
the
Voice
Control
System does
not
understand
you. X
Speak the phone number in groups
of digits, e.g. three to five digits
each. Voice Control System
individualization
i The individualization can only be
performed when the vehicle is stationary.
If you

drive off, the individualization will be
canceled.
After starting the session, the system will
guide you through the individualization by
means of acoustic instructions.
The individualization is used to adapt the
Voice Control System to your own voice and
to therefore improve speech recognition. This
does not affect the speech recognition of
other users.
Individualization consists of two stages:
R Digits
R Commands
You can activate individualization in the
COMAND system settings (Y page 80). A
dialog and screen displays will guide you
through the individualization process. The system can be reset to the factory
settings at any time.
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. 250
