Unlocking with KEYLESS-GO
Important safety notes
GWARNING
The vehicle exhaust system can become very
hot. If you use HANDS-FREE ACCESS, you
could burn yourself by touching the exhaust
system. There is a risk of injury. Always
ensure that you make the kicking movement
only within the detection range of the sensors.
!If the SmartKey is within the rear detection
range of KEYLESS-GO, the following situa-
tions, for example, could lead to the uninten-
tional opening of the trunk lid:
Rwhen using an automatic car wash
Rwhen using a power washer
Make sure that the SmartKey is at least 10 ft
(3 m) away from the vehicle.
General notes
Vehicles with KEYLESS-GO without carbon
package: you can unlock the trunk lid without
using your hands. This is useful if you have your
hands full. To do this, make a kicking movement
under the rear bumper with your foot.
74Trunk
Opening and closing

Observe the following points:
RCarry your KEYLESS-GO key about your per-
son. The SmartKey must be at the rear of the
vehicle in the detection range of KEYLESS-
GO.
RWhen making the kicking movement, make
sure that you are standing firmly on the
ground and that there is sufficient clearance
to the rear of the vehicle. You could otherwise
lose your balance, for example on ice.
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.
RUnlocking the trunk via the sensor does not
function while the engine is being started.
RDirt caused by road salt or snow around sen-
sors :may restrict functionality.
Using the trunk unlocking function via the
sensor with a prosthetic leg may restrict func- tionality.
RIf a KEYLESS-GO SmartKey is within the rear
detection range of KEYLESS-GO, the sensors
could be triggered. As a result, the trunk lid
could be opened unintentionally under the
following conditions:
-if you set something down or lift something
behind the vehicle
-if you 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 the trunk lid
from being unlocked unintentionally.
Operation
XTo unlock: kick into sensor detection
range :below the bumper with your foot.
The trunk lid opens slightly.
XTo open: lift the trunk lid.
XIf the trunk lid does not unlock after sev-
eral attempts: wait at least ten seconds then
kick under the bumper once again.
If you hold your foot under the bumper for too
long, the trunk lid does not unlock. Repeat the
leg movement more quickly if this occurs.
Unlocking from inside the vehicle
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.

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.

Opening and closing

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
becomes trapped, release the switch or press
the switch to open the side window again.
GWARNING
If children operate the side windows they
could become trapped, particularly if they are left unsupervised. There is a risk of injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
Side window reversing feature
The side windows are equipped with an auto-
matic reversing feature. If a solid object blocks
or restricts a side window from traveling
upwards during the automatic closing process,
the side window opens again automatically. Dur-
ing the manual closing process, the side window only opens again automatically after the corre-
sponding switch is released. The automatic
reversing feature is only an aid and does not
relieve you of the responsibility of paying atten-
tion 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
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
someone becomes trapped, press the switch
to open the side window again.
Opening and closing the side win-
dows
The switches for all side windows are located on
the driver's door. There is also a switch on the
front-passenger door for the corresponding side window.
The switch on the driver's door has priority.

steps above.
Problems with the side windows
GWARNING
If you close a side window again immediately after it has been blocked or reset, the side window
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 (Roadster)
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 or store heavy
objects on it. You will otherwise damage the
vehicle soft top and soft-top covers.
!When opening and closing the soft top,
make sure that:
Rthere is sufficient clearance above it, as the
soft top swings upwards
Rthere are no objects on the soft top or the
soft-top covers to the side
Rthe fabric is not dirty, wet or frozen
Rthe outside temperature is above -10 †
You could otherwise damage the soft top as
well as other parts of the vehicle.
Take the height of the vehicle into account when
opening and closing the soft top (
Ypage 291).
Make sure that the soft top is dry and clean
before opening or closing 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. 37 mph (60 km/h), to avoid
interrupting the closing process while slightly
exceeding this speed)
If there is a strong head wind, it may not be pos-
sible to close the soft top fully. In order to close
the soft top fully, reduce your speed or stop the
vehicle in accordance with the traffic condi-
tions.
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

Important safety notes
GWARNING
When opening or closing the soft top, there is a risk that parts of the body could become
trapped by moving parts such as the roof
mechanism, the trunk lid, or the side win-
dows. There is a risk of injury.
When opening or closing the roof, make sure
that no parts of the body are in the vicinity of
moving parts. Release the switch if somebody
becomes trapped.
GWARNING
If the vehicle speed exceeds 35 mph
(60 km/h), the soft top stops during the open- ing or closing process. This impairs your view
