Voice Control* introduction
Voice Control* introduction
The Voice Control System gives you the ca-
pability to control the following systems on
your vehicle using spoken commands:

Telephone* (page 289)

Navigation (page 296)

Address book (page 306)

Audio (page 309) (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 287) 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 330).
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.

Voice Control* introduction
Spelling
You may not need to spell the entire name
(street, intersection, city or point of inter-
est) especially if the name is lengthy. Spell-
ing the first three to five characters of the
name should be sufficient for the system
to recognize the name provided it is avail-
able on the navigation DVD.
The selection appearing on the COMAND
display is sorted based on your recognized
voice input and a matching algorithm.
You can use the commands “Next page” or
“Previous page” to scroll up or down in the
list.
Use the command “Correction” to start
over by again spelling the name.
Speak each character as clearly as you
can, especially when they sound very simi-
lar (d or e).Command types
The Voice Control System commands can
be categorized as:

General Commands
These are commands always available
to you as soon as the Voice Control
System is activated (for example
“Help” commands).

Local Commands
These are commands specific to the
currently active system shown in the
COMAND display (for example com-
mands to control the CD/DVD chang-
er).
For a complete list of commands
(
page 315).
Active System
The active system is the system currently
shown in the COMAND display.
If, for example, you listen to the radio while
the telephone system is active on the
COMAND display, you have to switch to
the radio using the command “Radio” be-
fore you can operate the radio.

al help windows also appear in the COMAND dis-

Some jurisdictions prohibit the driver from
using a cellular telephone while driving.
Whether or not prohibited by law, for safety
reasons, the driver should not use the cellu-
lar telephone while the vehicle is in motion.
Stop the vehicle in a safe location before
placing or answering a call.
If you nonetheless choose to use the mobile
phone while driving, please use the hands-
free feature and be sure to pay attention to
the traffic situation at all times. Use the mo-
bile phone only when road, weather and traf-
fic conditions permit. Otherwise, you may
not be able to observe traffic conditions and
could endanger yourself and others.

tion of the vehicle’s electronic system, pos-
sibly resulting in an accident and/or
personal injury.
