176 Voice Control
Overview
The following symbols indicate:
sthat you have to say something
tthat there is a voice output from the
voice control
uthat the system shows information
on the display.
You can use the voice control system to
operate the following systems depending
on the equipment in your vehicle:

Phone

Navigation

Address book

Audio (radio, satellite radio*,
DVD changer, memory card,

a new command with “Please repeat” or
“Please repeat your entry!”.
Overview
Operating Safety
G Warning
Please devote your attention first and fore-
most to the traffic situation you are in. While
the system permits hands-free phone oper-
ation, attention to traffic may be diverted
not only by physical operation of a phone,
but also by the distraction of a phone con-
versation while driving. As such, for safety
reasons, we encourage the driver to stop the
vehicle in a safe place before answering or
placing a phone call.
For safety reasons, you should only select a
destination when the vehicle is stationary.
While the navigation system provides direc-
tional assistance, the driver must remain fo-
cused on safe driving behavior, especially
attention to traffic and street signs, and
should utilize the system’s audio cues while
driving.
The navigation system does not supply any
information on stop signs, yield signs, traffic
regulations or traffic safety rules. Their ob-
servance always remains in the driver’s per-
sonal responsibility. DVD maps do not cover
all areas nor all routes within an area.
Traffic regulations always have priority over
any route recommendations given.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximate-
ly 13.5 m) every second.
G Warning
Navigation announcements are intended to
direct you while driving without diverting
your attention from the road and driving.
Please always use this feature instead of
consulting the map display for directions.
Consulting the symbols or map display for
directions may cause you to divert your at-
tention from driving and increase your risk
of an accident.
G Warning
Please do not use the Voice Control System
in an emergency, as the tone of your voice
may change in a stressful situation. This
could cause a delay in completing your
phone call in a timely manner. This could
distract you in an emergency situation and
cause you to be involved in an accident.

Usage

177 Voice Control
Overview
The voice control confirms important com-
mands to you and gives you instructions in
the event of incorrect entries.
Command types
Voice control distinguishes between the
following types of command:

Global commands:
These are commands which can be
called up at any time (e.g. help or
phone commands).

Local commands:
These are commands which are only
available for the active application (e.g.
“Enter destination” during navigation).
Active application
The local commands refer to the applica-
tion currently shown on the display and to
the audio source you are currently listen-
ing to.
For example, if you are listening to the ra-
dio while the navigation application is ac-
tive on the display, you can operate both
applications using voice control.To operate a different function using voice
control, you must first switch to that appli-
cation using the corresponding command.
Operation using the multi-function
steering wheel
i You can cancel the dialog with voice control
at any time.
Voice control is operational around half a
minute after COMAND is switched on.
Starting the dialog
Switch on the ignition (see the vehicle
Owner's Manual).
Press the ! button.
An acoustic signal confirms that the di-
alog has been started.
Give a command.
Interrupting the dialog
If a list appears on the display, you can use
the “Pause” command to interrupt the dia-
log. You can then select an entry using the
COMAND controller.
To resume the dialog with voice control,
press the ! button on the multifunction
steering wheel.

tem, a selection list is shown in the display
if voice control requires additional informa-

1Display
Entering numbers

Digits from “zero” to “nine” are permit-
ted.

Say the phone number in groups of
three to five digits.
Spell

The letters of the alphabet and the
numbers 0 - 9 are permitted.

Say the letters in groups of five to sev-
en letters.

i Using individualization, you can fine-tune
voice control to your own voice and thus improve
voice recognition. The process of individualiza-
tion is described in chapter “System Settings”
(
page 167).
i If you use individualization, it may impair
recognition of other users. Switch off individual-
ization if it makes recognition of other users
worse.
