Voice Control System introduction
Safety notes
GWarning!
Only use the Voice Control System when road
and traffic conditions permit you to do so.
Otherwise you could be involved in an
accident in which you or others could be
injured.
GWarning!
Please devote your attention first and
foremost to the traffic situation you are in.
While the system permits hands-free phone
operation, attention to traffic may be diverted
not only by physical operation of a phone, but
also by the distraction of a phone
conversation 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
directional assistance, the driver must remain
focused 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
observance always remains in the driver’s
personal responsibility. 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 (approximately
14 m) every second.
GWarning!
Navigation announcements are intended to
direct you while driving without diverting your
attention from the road and driving.
Please always use navigation announcements
instead of consulting the map display for
directions. Consulting the symbols or map
display for directions may cause you to divert
your attention from driving and increase your
risk of an accident.
Voice Control System introduction237Control systems221_AKB; 6; 20, en-USd2ugruen,Version: 2.11.8.12009-09-24T13:28:17+02:00 - Seite 237Z

GWarning!
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.
General information
Depending on vehicle equipment, you can
operate the following systems via the Voice
Control System:
RTelephone (Y page 245)
RNavigation (Y page 240)
RAddress book (Y page 249)
RAudio (Y page 252) (AM/FM radio,
Satellite radio, CD/DVD changer, MP3
mode (SD card, USB, Music Register, Media
Interface), AUX)
RVideo
You control these systems using spoken
commands. Moreover, controls such as the
buttons on the multifunction steering wheel
(Y page 238) allow you to keep your hands
on the steering wheel.
The Voice Control System recognizes
commands and number sequences,
irrespective of the speaker. To optimize
speech recognition for your voice follow the
individualization process (Y page 271).
You can use the Voice Control System to call
up all of COMAND’s main menu items.
The commands can be spoken without
pausing between the individual words. If an
unavailable or incorrect command is used,
the Voice Control System will prompt you for
a new command by asking “Please repeat” or
“Please repeat your entry”.
The Voice Control System will confirm
important commands and inform you in case
of incorrect entries.
iTo support the user, the Voice Control
System contains an extensive help function
(Y page 267).
You can use the commands “Continue” or
“Back” to scroll up or down in lists.
The command “Correction” lets you repeat
the entry.

Important notes on using KEYLESS-GO
R You can also use the SmartKey with
KEYLESS-GO like a normal SmartKey
( Y page 274).
R You can combine KEYLESS-GO functions
with normal SmartKey functions (e.g.
unlocking with KEYLESS-GO and locking
with button &).
R Always carry the SmartKey with you.
R Never store the SmartKey together with
- electronic items such as a mobile phone
or another SmartKey
- metallic objects such as coins or metal
foil
Doing so could impair the function of the
KEYLESS-GO system.
R To lock or unlock the vehicle, the SmartKey
must be located outside the vehicle within
approximately 3 ft (1 m) of a door or the
trunk.
R When the vehicle has been parked for more
than 72 hours, the KEYLESS-GO function is
deactivated. Pull an outside door handle
and switch on the ignition once to activate
the KEYLESS-GO function.
R If the SmartKey is positioned farther away
from the vehicle, the system may no longer
recognize the SmartKey. The vehicle
cannot be locked or the engine started via
the KEYLESS-GO system.
R If the SmartKey is removed from the vehicle
(e.g. if a passenger exits the vehicle with
the SmartKey)
- when pressing the KEYLESS-GO start/
stop button or trying to lock the vehicle
with the outside door handle the
message Key Not Detected appears in
the multifunction display
- with the engine running, the red message

R If you have started the engine with the
KEYLESS-GO start/stop button, you can
turn it off again by
- pressing the KEYLESS-GO start/stop
button
- inserting the SmartKey into the starter
switch when the vehicle is at a standstill

of the vehicle and
- an outside door handle is splashed with
water
or
- you attempt to clean an outside door
handle
R Remember that the engine can be started
by anyone with a SmartKey that is left
inside the vehicle.
Possibility 1 (One SmartKey in the vehicle,
one SmartKey outside the vehicle):
If you leave the SmartKey behind when
exiting and locking the vehicle, no message
appears in the multifunction display.276Locking and unlockingControls in detail
