Important safety notes
G
DANGER
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Exhaust
gases can enter the vehicle interior if the
trunk lid is open while 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. G
WARNING
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.
The opening dimensions of the trunk lid can be
found in the "Vehicle data" section
(Y page 293).
If the rear spoiler has been extended manually,
the height when opened is higher by this
amount. If in doubt, retract the rear spoiler again manually before opening the trunk lid
(Y page 229).
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
(Y page 218). Opening/closing from outside
Opening X

The trunk lid opens slightly.
X Lift the trunk lid.
Closing X
Pull the trunk lid down using recess 0043and let

button on the SmartKey or with KEYLESS-GO
(Y page 67). Unlocking with KEYLESS-GO
Important safety notes G
WARNING
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. 74
TrunkOpening and closing

!
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:
R when using an automatic car wash
R when 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.
Observe the following points:
R Carry 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.
R When 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. R
Always ensure that you only make the kicking
movement within the detection range of sen- sors 0043.
R Stand at least 12 in (30 cm) away from the
rear area while doing so.
R Do not come into contact with the bumper
while making the kicking movement. Other-
wise, the sensors may not function correctly.
R Unlocking the trunk via the sensor does not
function while the engine is being started.
R Dirt caused by road salt or snow around sen-
sors 0043may restrict functionality. Using the trunk unlocking function via the
sensor with a prosthetic leg may restrict func-
tionality.
R If 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 X
To unlock: kick into sensor detection
range 0043below the bumper with your foot.
The trunk lid opens slightly.
X To open: lift the trunk lid.
X If 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

dow during the opening procedure. If some-
body becomes trapped, release the switch or pull the switch to close the side window again. G

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 to pay attention
when closing a side window. G
WARNING
The reversing feature does not react:
R to soft, light and thin objects, e.g. small fin-
gers
R while adjusting
This means that the reversing feature cannot
prevent someone being trapped in these sit-
uations. There is a risk of injury.

proximity during the closing procedure. If someone becomes trapped, press the
0062
