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.

three to five digits.

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

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).

recognition of other users. Switch off individual-
ization if it makes recognition of other users
worse.

Phone operation
“Phone”
Use the “Phone” command to select the
phone application. Use this command if
you wish the digits entered to be shown on
the display.
“Help Phone”
Voice control has an extensive help func-
tion. Using the “Help Phone” command,
you can have all the essential commands
for the phone read out (
page 201).
“Enter PIN”
Use the “Enter PIN” command to input the
PIN code (Personal Identification Number)
for your phone. To do this, the phone must
be connected via Bluetooth. When you
have given the command, voice control
prompts you to enter the PIN code.
Say the PIN code in the form of a continu-
ous string of digits or as blocks of digits,
e.g. three to five digits.
Digits 0 to 9 are permitted. Voice control
repeats the digits it recognizes after each
block of digits (with a pause of approxi-mately half a second between each block
of digits) and waits for you to continue
speaking.

sEnter PIN
tPlease say the PIN code
sZero one three three
tZero one three three

code three times in a row. Use the PUK (personal
unblocking key) to unblock the card.

the phone keypad – see the phone operat-
ing instructions.

mitted.
“Plus” replaces the international dialing
code, e.g. “00”.

tinuous string of digits or as blocks of dig-
its, e.g. three to five digits.Voice control repeats the digits it recogniz-
es after each block of digits (with a pause
of about half a second between each block
of digits) and waits for you to continue
speaking.
Example of dialog:
sDial number
tPlease say the number
sZero one three zero
tZero one three three

G Warning
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’ 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
During route guidance, you will not receive
information on:

traffic lights

stop and yield signs

parking or stopping zones

one-way streets

narrow bridges, or

other traffic regulation data.
You should therefore always strictly observe
traffic regulations while driving. Drive care-
fully and always obey traffic laws and road
signs, even if they contradict navigation sys-
tem instructions.
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.
