Trunk
Important safety notes
GWARNING
If objects, luggage or loads are not secured or
not secured sufficiently, they could slip, tip
over or be flung around and thereby hit vehicle
occupants. There is a risk of injury, particu-
larly in the event of sudden braking or a sud-
den change in direction.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey.
!The trunk lid swings upwards when
opened. Therefore, make sure that there is
sufficient clearance above the trunk lid.
iYou can limit the opening angle of the
trunk lid in COMAND; see the separate
operating instructions.
iThe opening dimensions of the trunk lid
can be found in the "Vehicle data" section
(
Ypage 406).
Do not leave the SmartKey in the trunk. You
could otherwise lock yourself out.
You should preferably place luggage or loads
in the trunk. Observe the loading guidelines
(
Ypage 300).
Obstacle recognition with trunk lid
reversing feature
On vehicles with trunk lid remote closing fea- ture, the trunk lid is equipped with automatic
obstacle recognition with reversing feature. If
a solid object blocks or restricts the trunk lid
when automatically opening or closing, this
procedure is stopped. If the trunk lid is stop-
ped during the closing procedure, it will open again automatically. The automatic obstacle
recognition with reversing feature is only an
aid. It is not a substitute for your attentive-
ness when opening and closing the trunk lid.
GWARNING
The reversing feature does not react:
Rto soft, light and thin objects, e.g. small fin-
gers
Rover the last 1/3 in (8 mm) of the closing
movement
This means that the reversing feature cannot
prevent someone being trapped in these sit-
uations. There is a risk of injury.
Make sure that no body parts are in close
proximity during the closing procedure.
If somebody becomes trapped:
Rpress the Fbutton on the SmartKey, or
Rpull or press the remote operating switch
on the driver's door or
Rpress the closing or locking button on the
trunk lid
Opening/closing automatically from

Important safety notes
GWARNING
Parts of the body could become trapped dur-
ing automatic closing of the trunk lid. More-
over, people, e.g. children, may be standing in the closing area or may enter the closing area
during the closing process. There is a risk of
injury.

Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Exhaust
gases can enter the vehicle interior if the
trunk lid is open when the engine is running,
especially if the vehicle is in motion. There is a
risk of poisoning.
Always switch off the engine before opening
the trunk lid. Never drive with the trunk lid
open.
!The trunk lid swings upwards when
opened. Therefore, make sure that there is
sufficient clearance above the trunk lid.
iThe opening dimensions of the trunk lid
can be found in the "Vehicle data" section
(
Ypage 406).

Vehicles with trunk lid remote closing
feature and KEYLESS-GO:when all the
doors are closed, you can simultaneously
close the trunk lid and lock the vehicle. The
SmartKey must be located to the rear of the
vehicle.
XPress and release locking button ;on the
trunk lid.
If a KEYLESS-GO key is detected outside
the vehicle, the trunk lid closes and the
vehicle locks.
iIf KEYLESS-GO detects a SmartKey in the
trunk, the trunk lid opens again after it is
closed.
If KEYLESS-GO detects a second SmartKey
outside the vehicle, the trunk lid remains
closed.
HANDS-FREE ACCESS
Important safety notes
GWARNING
The vehicle's exhaust system may be very hot. You could burn yourself by touching the
exhaust system if you use HANDS-FREE
ACCESS. There is a risk of injury. Always
ensure that you only make the kicking move-
ment within the detection range of sensors.
!If the SmartKey is within the rear detec-
tion range of KEYLESS-GO, the following
situations, for example, could lead to the
unintentional opening of the trunk:
Rusing a car wash
Rusing a power washer
Make sure that the SmartKey is at least
10 ft (3 m) awayfrom the vehicle.
General notes
With KEYLESS-GO and HANDS-FREE
ACCESS, you can open or close the trunk lid
or stop the procedure without using your
hands. This is useful if you have your hands full. To do this, make a kicking movement
under the bumper with your foot.
Observe the following points:
RCarry your KEYLESS-GO key about your
person. The KEYLESS-GO key must be in
the rear detection range of the vehicle.
RWhen making the kicking movement, make
sure that you are standing firmly on the
ground and that there is sufficient clear-
ance to the rear of the vehicle. You could
otherwise lose your balance, e.g. on ice.
RAlways ensure that you only make the kick-
ing movement within the detection range of
sensors :.
RStand at least 12 in (30 cm) away from the
rear area while doing so.
RDo not come into contact with the bumper
while making the kicking movement. Oth-
erwise, the sensors may not function cor-
rectly.
RHANDS-FREE ACCESS does not function
when the engine is started.
RIf a KEYLESS-GO key is within the rear
detection range of KEYLESS-GO, HAND-
FREE ACCESS could be triggered. The trunk
lid could thus be opened or closed unin-
tentionally, for example, if you:
-sit on the edge of the trunk.
-set something down or lift something up
behind the vehicle.
-polish the rear of the vehicle.
Do not carry the KEYLESS-GO key about
your person in these situations or in situa-

tions similar to these. This will prevent the
unintentional opening/closing of the trunk.
RDirt caused by road salt around sensors:
may restrict functionality.
RUsing the HANDS-FREE ACCESS with a
prosthetic leg may restrict functionality.
Operation
XTo open/close: kick into sensor detection
range :under the bumper with your foot.
You will hear a warning tone while the trunk
lid is opening or closing.
XIf the trunk lid does not open after sev-
eral attempts: wait at least ten seconds
then move your leg under the bumper once
again.
iIf you hold your foot under the bumper for
too long, the trunk lid does not open or
close. Repeat the leg movement more
quickly if this occurs.
To stop the opening or closing procedure:
Rkick with your leg in the sensor detection
range :under the bumper or
Rpress the closing button in the trunk lid or
Rpress the Fbutton on the SmartKey
If the trunk lid closing procedure has been
stopped:
Rmove your foot under the bumper again and
the trunk lid will open.
If the trunk lid opening procedure has been
stopped:
Rmove your foot under the bumper again and
the trunk lid will close.

dows from traveling upwards during the auto-
matic closing process, the side window opens
again automatically. During the manual clos-
ing process, the side window only opens
again automatically after the corresponding
switch is released. However, the automatic
reversing feature is only an aid and does not
relieve you of the responsibility of paying
attention when closing a side window.
GWARNING
The reversing feature does not react:
Rto soft, light and thin objects, e.g. small fin-
gers
Rwhile resetting
