Important safety notes
GWARNING
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.
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.
You can limit the opening angle of the trunk lid in
the multimedia system; see the Digital Opera-
tor's Manual.
The opening dimensions of the trunk lid can be
found in the "Vehicle data" section
(
Ypage 334).
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 254).
Obstruction detection with reversing
feature for the trunk lid
Vehicles with trunk lid remote closing fea-
ture:
The trunk lid is equipped with automatic
obstruction detection with a reversing feature. If
a solid object blocks or restricts the trunk lid
when automatically opening or closing, this pro-
cedure is stopped. If the trunk lid is stopped
during the closing procedure, it will open again
automatically. The automatic obstruction detec-
tion with reversing feature is only an aid. It is not a substitute for your attentiveness when open-
ing and closing the trunk lid.
GWARNING
The reversing feature does not respond:
Rto soft, light and thin objects, e.g. fingers
Rover the last 1/3 in (8 mm) of the closing
movement
The reversing feature cannot prevent some-
one from becoming trapped in these situa-
tions in particular. 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, or
Rpress the top of the star on the trunk lid

Opening and closing

RAlways ensure that you only make the kicking
movement within the detection range of sen-
sors:.
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. Other-
wise, the sensors may not function correctly.
RHANDS-FREE ACCESS does not function
when the engine is started.
RDirt caused by road salt around sensors :
may restrict functionality.
RUsing the HANDS-FREE ACCESS with a pros-
thetic leg may restrict functionality.
RIf a KEYLESS-GO key is within the rear detec-
tion range of KEYLESS-GO, HANDS-FREE
ACCESS could be triggered. The trunk lid
could thus be opened or closed unintention-
ally, 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 situations sim-
ilar to these. This will prevent unintentional
opening or closing of the trunk lid.
Operation
XTo open or close: kick into sensor detection
range :under the bumper with your foot.
A warning tone will sound while the trunk lid is
opening or closing.
XIf the trunk lid does not open or close after
several attempts: wait at least ten seconds
then move your leg under the bumper once
again.
If 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, you
have the following options:
RKick with your foot in sensor detection
range
:under the bumper.
RPress the closing button on the trunk lid.
RPress the top of the star on the trunk lid.
RPress the Fbutton on the SmartKey
If the trunk lid closing procedure has been stop-
ped:
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

Side windows
Important safety notes
GWARNING
While opening the side windows, body parts
could become trapped between the side win-
dow and the door frame as the side window
moves. There is a risk of injury.
Make sure that nobody touches the side win-
dow during the opening procedure. If some-
body becomes trapped, release the switch or
pull the switch to close the side window again.
GWARNING
While closing the side windows, body parts in
the closing area could become trapped. There is a risk of injury.
When closing make sure that no parts of the
body are in the closing area. If somebody

the switch to open the side window again.
Side window reversing feature
The front side windows are equipped with an
automatic reversing feature. If a solid object
blocks or restricts the upward movement of one
of the front side windows during the automatic
closing process, the side window opens again
automatically.
During the manual closing process, the side win- dows in the doors or in the rear open automat-
ically after the corresponding button is released.
However, the automatic reversing feature is only
an aid and does not relieve you of the responsi-
bility of paying attention when closing a side
window.

SmartKey in the ignition and you press or pull a
button while the engine is switched off. This is
carried out by means of a brief radio connection

closes with increased or maximum force. The reversing feature is then not active. Parts of the
body could be trapped in the closing area in the process. This poses an increased risk of injury or
even fatal injury.
Make sure that no parts of the body are in the closing area. To stop the closing process, release
the switch or push the switch again to reopen the side window.

Soft top
Important safety notes
GWARNING
If you do not fully open/close the soft top, the
soft-top hydraulics depressurize after a short
time. This causes the soft top to lower unex-
pectedly and may cause you or others to be
trapped. There is a risk of injury.
Always open or close the soft top completely.
!Never sit on the soft-top compartment
cover or stow heavy objects there. You will
otherwise damage the soft top and soft-top
compartment cover of the vehicle.
!When opening and closing the soft top,
make sure that:
Rthere is sufficient clearance above it, as the soft top swings upwards.
Rthe trunk is only loaded to below the trunk
partition.
Rthe trunk partition is not pushed up by the
load.
Rthe trunk lid is closed.
Rthere are no objects on the soft-top com-
partment cover
Rthe fabric is not dirty, wet or frozen. You could otherwise damage the soft top,
trunk and other parts of the vehicle.
Take the height of the vehicle into account when
opening and closing the soft top (
Ypage 334).
Make sure that the soft top is dry and clean
before opening it. Otherwise, water or dirt could
enter the vehicle interior or trunk.
You can open or close the soft top:
Rwhen the vehicle is stationary or
Rwhen you do not exceed a speed of 31 mph
(50 km/h) (Max. 35 mph (60 km/h), to avoid
interrupting the closing process while slightly
exceeding the speed limit).
If there is a strong head wind, it may not be pos-
sible to close the soft top fully. In this case,
reduce speed or stop in order to close the soft
top fully.
For safety reasons, Mercedes-Benz recom-
mends that you only open or close the soft top
when the vehicle is stationary.
If the soft top does not open or close fully, the
soft-top hydraulics are depressurized and the
soft top is lowered:
Rafter approximately 7 minutes when the igni-
tion is switched on
Rafter about 20 seconds if the ignition is
switched off
