G
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.i
If Russian or Chinese is set as the system
language, the navigation announcements are in
English. You will find how to set the system lan-
guage on (
page 262).
Navigation announcements are muted during
telephone calls. You can, however, call up a cur-
rent announcement at any time. You can also
call up a current announcement at any time if
you have missed an announcement.

ton.
If you switch COMAND off by removing the
SmartKey from the starter switch and then
switch the ignition back on after more than
3 minutes, the announcements are automatical-
ly switched back on.

368 Controls in detailLocking and unlockingPower 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 512).
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 267).
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.
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 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
