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.
!Only close the trunk once the roof is low-
ered completely. Otherwise, you could
damage the roof. If you close the trunk lid before the roof is
lowered completely, the loading aid switch
lights up and a warning tone sounds.
iOpening dimensions of the trunk lid
(
Ypage 608).
iWith the roof open, you can use the load-
ing aid (

in the trunk to make loading easier. For this
purpose, you can also open the trunk par-
tition.
The trunk partition must be closed again
after loading. It will otherwise not be pos-
sible to close the roof.

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) away from 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
Trunk93

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, HANDS-
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: move your foot in sensor
detection range :using your leg.
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:
Rmove your foot in sensor detection
range :under the bumper, or
Rpull the handle on the outside of the trunk
lid or
Rpress the closing button on the trunk lid, or
Rpull or press the remote operating switch
on the driver's door or
