304 Control systemsVoice Control introductionThe Voice Control System gives you the ca-
pability to control the following systems on
your vehicle using spoken commands:
Telephone* (
page 308)
Navigation (
page 315)
Address book (
page 325)
Audio (
page 329) (AM/FM radio,
CD/DVD changer, MP3 player)You control these systems using spoken
commands. Moreover, controls such as
the buttons on the multifunction steering
wheel (
page 306) allow you to keep your
hands on the steering wheel.
The command vocabulary consists of
approximately 300 ready to use phrases.
The Voice Control System recognizes com-
mands and number sequences, irrespec-
tive of the speaker. To optimize speech
recognition for your voice follow the indi-
vidualization process (
page 350).
You can use the Voice Control System to
call up all of COMAND’s main menu items,
with the exception of the main menus for
“Vehicle” and “Navi”.The commands and digit sequences can be
spoken without pausing between the indi-
vidual words. If an unavailable or incorrect
command is used, the Voice Control Sys-
tem will prompt you for a new command by
asking “Please repeat” or “Please repeat
your entry”.
In order to provide for a safe and comfort-
able dialog, the Voice Control System ac-
knowledges important commands.
310 Control systemsVoice Control telephone“Dial number”
You can dial a phone number using the
command “Dial number”.
Digits from “Zero” to “Nine” may be used.
The phone number must be spoken
as a continuously spoken string of
digits, or
in digit blocks (three to five digits in
each block).
After each digit block (separate the digit
blocks by using an approximately
0.5 second pause), the Voice Control Sys-
tem repeats the recognized digits and
waits until you continue speaking.
When dialing 1800 numbers, you may pro-
nounce the first four digits as “One eight
hundred” and the system will recognize the
spoken entries as “One eight zero zero”.
All other numeric entries must be spoken
as individual numbers.Sample dialog:

peating the digits, the system will prompt
you to continue your input.

G
For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint so that it is as
close to the head as possible and the center
of the head restraint supports the back of
the head at eye level. This will reduce the po-
tential for injury to the head and neck in the
event of an accident or similar situation.
Do not drive the vehicle without the seat
head restraints. Head restraints are intend-
ed to help reduce injuries during an acci-
dent.
