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* telephone
“Dial number”
You can dial a phone number using the
command “Dial number”.
Digits from “Zero” to “Nine” may be used.
The phone number must be spoken

as a continuously spoken string of
digits, or

in digit blocks (three to five digits in
each block).
After each digit block (separate the digit
blocks by using an approximately 0.5 sec-
ond pause), the Voice Control System re-
peats the recognized digits and waits until
you continue speaking.
When dialing 1800 numbers, you may pro-
nounce the first four digits as “One eight
hundred” and the system will recognize the
spoken entries as “One eight zero zero”.
All other numeric entries must be spoken
as individual numbers.Sample dialog:
sDial number
tPlease say the number
sOne two three
tOne two three
sFour five six seven
tFour five six seven

tDialing“Confirm”
Using the command “Confirm” will repeat
all digits spoken up to that point. Upon re-
peating the digits, the system will prompt
you to continue your input.

Locking and unlocking
Power closing assist for doors and
trunk lid
It is not necessary to slam the door or
trunk lid closed. An electrical power-assist-
ed mechanism draws doors and trunk lid
closed quietly and automatically once door
and trunk lid has been latched. When the
electrical power-assisted mechanism has
stopped, doors and/or trunk can be
re-opened.
Power closing assist for doors: Press
the doors gently past the initial engage
position into the lock.
The doors close automatically.
Power closing assist for trunk lid:
Press the trunk lid gently into its lock.
The trunk closes automatically.For more information on closing the trunk
lid, see “Closing trunk” (
page 480).
Automatic central locking
The doors and the trunk automatically lock
when the ignition is switched on and the
wheels are turning at vehicle speeds of ap-
proximately 9 mph (15 km/h) or more. The
locking knobs in the doors move down.
You can open a locked door from the in-
side. Open door only when conditions are
safe to do so.
You can deactivate the automatic locking
using the COMAND system (
page 245).
Warning!G
To prevent possible personal injury, always
keep hands and fingers away from the door
or trunk lid opening when closing a door or
the trunk. Be especially careful when small
children are around.
In case of danger, pull the inside or outside
door handle, or pull the trunk lid handle.
To prevent personal injury, never actuate
the closing assist mechanism by tampering
with the door or trunk lid latch.
Warning!G
Only drive with the doors closed. Otherwise,
one or more of the doors could open while
the vehicle is in motion, putting you and/or
others at risk.
Warning!G
Only drive with the trunk closed as, among
other dangers such as blocked visibility, ex-
haust fumes may enter the vehicle interior.
These fumes may be damaging to your
health.
iThe doors are designed to unlock automati-
cally after an accident if the force of the impact
exceeds a preset threshold.
The vehicle locks automatically when the ignition
is switched on and the wheels are turning at ve-
hicle speeds of approximately 9 mph (15 km/h)
or more. You could therefore lock yourself out
when the vehicle

is pushed or towed

is on a test stand

Seats
Seat adjustment
Warning!G
All seat, head restraint adjustments, as well
as fastening of seat belts, must be done be-
fore the vehicle is put into motion.
Warning!G
Do not adjust the driver’s seat while driving.
Adjusting the seat while driving could cause
the driver to lose control of the vehicle.
Never ride in a moving vehicle with the seat
back in an excessively reclined position as
this can be dangerous. You could slide un-
der the seat belt in a collision. If you slide
under it, the seat belt would apply force at
the abdomen or neck. That could cause se-
rious or fatal injuries. The seat backrest and
seat belts provide the best restraint when
the wearer is in a nearly upright position and
seat belts are properly positioned on the
body.
Warning!G
Your seat must be adjusted so that you can
correctly fasten your seat belt
(
page 368).
Observe the following points:

Adjust the backrest until your arms are
slightly angled when holding the steer-
ing wheel.

Adjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely. The po-
sition should be as far back as possible
with the driver still able to operate the
controls properly.

Adjust the head restraint so that it is as
close to the head as possible and the
center of the head restraint supports
the back of the head at eye level.

Never place hands under the seat or
near any moving parts while a seat is be-
ing adjusted.
Failure to do so could result in injury to per-
sons.
Warning!G
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle.
Even with the SmartKey or SmartKey with
KEYLESS-GO* removed from the starter
switch or the SmartKey with KEYLESS-GO*
removed from the vehicle, the power seats
can be operated when the respective door is
open. Therefore, do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. A child’s unsupervised ac-
cess to a vehicle could result in an accident
and/or serious personal injury.
