302 Control systemsVoice Control* individualizationThe individualization is used to adapt the
Voice Control System to your own voice
and to therefore improve speech recogni-
tion. This does not affect the speech rec-
ognition of other users.
Individualization consists of two stages:

Digits


Commands
You can activate individualization in the
COMAND system settings (
page 215).
A dialog and screen displays will guide you
through the individualization process.
The system can be reset to the factory set-
tings at any time.
i
The individualization can only be performed
when the vehicle is stationary.
If you drive off, the individualization will be can-
celed.
After starting the session, the system will guide
you through the individualization by means of
acoustic instructions.
i
You may wish to complete only a portion of
the individualization process.
Completing the digits portion alone may result in
an improved recognition rate.
Individualization can be exited at any time. The
data trained, however, will only be retained if a
given individualization portion is completed and
the data is stored when prompted to do so by the
system.

313 Controls in detail
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.
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 223).
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.
i
The doors are designed to unlock automati-
cally after an accident if the force of the impact
exceeds a preset threshold. The vehicle locks au-
tomatically when the ignition is switched on and
the wheels are turning at vehicle speeds of ap-
proximately 9 mph (15 km/h) or more. You
could therefore lock yourself out when the vehi-
cle


is pushed or towed


is on a test stand

mination of the area in the direction into
which you are turning.
Corner-illuminating lamps will operate
with:

the engine running


during darkness


the headlamps switched on
Switching on corner-illuminating lamps

Depending on whether you are turning
left or right, switch on the left or right
turn signal (
page 342).The respective corner-illuminating
lamp comes on and illuminates the
area in the direction into which you are
turning.Switching off the corner-illuminating
lamps
The combination switch for the turn signal
resets automatically after major steering
wheel movements. This will switch off the
corner-illuminating lamps if they were acti-
vated by switching on the left or right turn
signal.
If the turn signal should stay on after mak-
ing the turn, the turn signal and corner-illu-
minating lamp can be switched off by
returning the combination switch to its
original position.
i
The corner-illuminating lamps function is not
available at a vehicle speed above 25 mph
(40 km/h).
i
The corner-illuminating lamps will come on
automatically up to a speed of approximately
25 mph (40 km/h) depending on the steering
angle, even if you did not switch on either turn
signal. If the corner-illuminating lamps came on
automatically, they will also go out automatically
depending on the steering angle.
i
If you have switched on the turn signal for
one side but turn the steering wheel in the other
direction, the corner-illuminating lamp lights up
on the side of the turn signal.
i
The corner-illuminating lamps temporarily
light up on both sides of the vehicle if you turn
the steering wheel in one direction and then in
the other direction shortly thereafter.
i
When you shift the automatic transmission
in reverse gearR, the inverse corner-illuminating
lamp comes on automatically depending on the
steering direction and steering angle.
The turn signal has no influence on the corner-il-
luminating lamp on the outside of the curve.
i
If you are driving faster than 25 mph
(40 km/h) when activating the turn signal indica-
tor, the corner-illuminating lamp function is
switched off.
i
The corner-illuminating lamp may remain lit
for a short time. The corner-illuminating lamp
lights up for no more than 20 seconds with the
vehicle standing still. It is then switched off even
if the turn signal is still switched on or you have
turned the steering wheel to full lock.
