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 501).
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 263).
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
Make sure the trunk is closed when the en-
gine is running and while driving. Among
other dangers, deadly carbon monoxide
(CO) gases may enter the vehicle interior re-
sulting in unconsciousness and death.
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

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 belt would apply force at the ab-
domen or neck. That could cause serious or
fatal injuries. The seat backrest and seat
belts provide the best restraint when the
wearer is in a nearly upright position and
belts are properly positioned on the body.
Warning!
G
Your seat must be adjusted so that you can
correctly fasten your seat belt
(page 388).
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 an accident
and/or serious personal injury.
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. Therefore, do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. A child’s un-
supervised access to a vehicle could result
in an accident and/or serious personal inju-
ry.

make sure the seat, if occupied, is as far
from the passenger front air bag as possi-
ble.
Otherwise, the passenger could be seriously
or even fatally injured in the event of an ac-
cident or braking maneuver.
Make sure no one is caught or injured while
the seat is being adjusted.

supervised access to a vehicle could result
in an accident and/or serious personal inju-
ry.

Warning!
G
The seat belts provide protection only with
the backrest locked in place. Therefore, the
backrest must be locked in place with the
vehicle in motion. Do not drive the vehicle
when the backrest is not locked in place.
If the warning message:
Lock Seat Backrest
Front Right
or
Lock Seat Backrest
Front Left
is displayed in the multifunction display,
then the respective backrest is not engaged
in its lock. Carefully slow down, and drive
with caution to an area which is in a safe dis-
tance from the roadway. Always provide suf-
ficient room behind the backrest and fold
the backrest all the way back until it locks in
place.
The warning message is no longer displayed
as soon as the backrest is locked in place. If
both backrests are locked in place and the
warning message is still displayed, have the
system checked at an authorized
Mercedes-Benz Center immediately.
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.
The power seats can also be operated with
the driver’s or passenger door open. Do not
leave children unattended in the vehicle or
with access to an unlocked vehicle. A child’s
unsupervised access to a vehicle could re-
sult in an accident and/or serious personal
injury.
Never place hands under seat or near any
moving parts during a seat adjustment pro-
cedure.
!
The automatic seat slide is provided with a
safety feature.
The automatic process is interrupted if the back-
rest of the sliding seat is pushed against an oc-
cupant or object. The seat will slide forward and
stop.
Investigate and correct the cause of interruption.
Now use memory button (
page 386) or seat
adjustment switch (
page 369) to bring the
seat into the desired position.
When folding the backrest forward from a re-
clined position, and then folding it back, the
backrest stops in a more upright position for the
safety of any rear-seat passenger. Adjust the
backrest until your arms are slightly angled when
holding the steering wheel (
page 369).
