Voice command
Voice command system
The concept
The voice command system allows you to
control operation of various vehicle sys-
tems without ever removing your hands
from the steering wheel. The system oper-
ates on the basis of voice commands that
you will learn easily after using them a few
times. In many cases, the voice command
system supports you with announcements
or questions while you are making your
entries.
The voice command system transforms
your oral commands and dialog answers
into control signals for the selected sys-
tems.
Please take the time to acquaint your-
self with how a particular system
operates before proceeding to control it
using the voice command system.<
Symbols used
{...} Verbal instructions to use with the
voice command system.
{{...}} Identifies the answers generated by
the voice command system.

Speaking commands
Activating voice command system
Briefly press the button on the steering
wheel.
A signal tone and "SVS active" in the Info
Display, refer to page 26, indicate that the

off" appears in the Info Display, refer to
page 26.<
Voice commands
The voice command system operates on
the basis of specific, predefined com-
mands; these commands should be spo-
ken precisely as indicated. You can have
the possible commands read back at any
stage. To do so, say the command
{Options}.
In addition to the commands described,
there are often other commands that run
the same function. Instead of {Options},
you can, for example, also say
{What now}.
*
These sections contain information on
using the voice command system.
{Cancel}.

Voice command
26 More detailed commands such as {Change
scale} instead of {Scale} are also often
possible.
Short commands
With the {Main menu} level, you can run
certain functions directly with short com-
mands, refer to page 28, without having to
open an equipment level.
For example, if you want to dial a phone
number, you do not have to say
rather you can say directly
Special commands
Special commands are available for spe-
cific systems. In this Owner's Manual you will find these commands in the sections
describing the individual systems.
Displays in the Info Display
The Info Display shows you what the voice
command system has understood in line 2,
while also indicating which voice command
or question is currently active in line 1.
In addition, any error messages are also
displayed.
Selecting the navigation scale Ð an example
Start the dialog:
Briefly press the button on the steering

Notes
Do not use the voice command sys-
tem to make emergency calls. Your
voice and habitual tone could be affected
by stressful situations, as a result of which
the process of establishing the telephone
connection could be unnecessarily
delayed. Instead, use the emergency call
button near the interior rearview mirror,
refer to page 177.<
Environmental conditions
The voice command system uses a special
hands-free microphone located in the front
of your vehicle's headliner. Although the
system is designed to filter out ambient
noise, you can help ensure that your com-
mands will be understood by observing the
following instructions:
>Speak smoothly and clearly, at a normal
volume. Do not place any unusual
stress on individual syllables, and avoid
pauses
>Do not speak while the voice command
system is talking
>Keep the doors, windows and glass
roof closed to prevent interference from
ambient noise
>Avoid other sources of noise in the
vehicle while speaking, and ask other
vehicle occupants to refrain from talk-
ing while you are using the system
>The hands-free microphone is aimed
toward the driver. This means that the
system might be unable to register the
voices of other vehicle occupants prop-
erly.
The notebook
Recording a note
You can store approx. ten minutes of
spoken text Ð either as a single entry or

To terminate recording:
Press the button for a long period.
When recording notes, the voice
command system does not respond
to the {Cancel} command. The text check-
ing function for command words is deacti-
vated in this case so that you can speak
any desired text for your notes. This feature
saves you from having to concentrate on
avoiding any command words.<
