Cargo compartment
Important safety notes
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. If the tailgate is open when the engine is running, particu-
larly if the vehicle is moving, exhaust fumes
could enter the passenger compartment.
There is a risk of poisoning.
Turn off the engine before opening the tail-
gate. Never drive with the tailgate 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.
68Cargo compartment
Opening and closing

!The tailgate swings upwards and out when
opening. Therefore, make sure that there is
sufficient space above the tailgate.
The opening dimensions of the tailgate can be
found in the "Vehicle data" section
(
Ypage 286).
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 tailgate
(
Ypage 222).
You can switch the cargo compartment lamp on
and off manually on the overhead control panel
(
Ypage 89).
Do not leave the SmartKey in the cargo com-
partment. You could otherwise lock yourself
out.
You should preferably place luggage or loads in
the cargo compartment. Observe the loading
guidelines (
Ypage 209).
Opening/closing from outside
Opening

XLock the vehicle if necessary with the &
button on the SmartKey or with KEYLESS-GO
(
Ypage 61).
Unlocking with KEYLESS-GO
Important safety notes
GWARNING
The vehicle's exhaust system may be very hot. If you unlock the cargo compartment with
KEYLESS-GO, you could burn yourself by
touching the exhaust system. There is a risk of
injury. Always ensure that you only make the
kicking movement within the detection range
of 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 tailgate:
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
Vehicles with KEYLESS-GO without carbon
package: you can unlock the tailgate 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.
Cargo compartment69
Opening and closing
Z

Observe the following points:
RCarry your KEYLESS-GO key about your per-
son. 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 clearance
to the rear of the vehicle. You could otherwise
lose your balance e.g. 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 with KEYLESS-GO does not func-
tion when the engine is started.
RDirt caused by road salt around sensors :
may restrict functionality.
Using 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, the sensors could
be triggered. Therefore, the tailgate cannot be
unlocked unintentionally if, for example, you:
-sit on the edge of the cargo compartment.
-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 prevents the tailgate from
being unlocked unintentionally.
Operation
XTo unlock: kick into sensor detection
range :below the bumper with your foot.
The tailgate opens slightly.
XTo open: raise the tailgate.
XIf the tailgate does not unlock after sev-
eral attempts: wait at least ten seconds and
then kick under the bumper once again.
If you hold your foot under the bumper for too
long, the tailgate does not unlock. Repeat the
leg movement more quickly if this occurs.
Unlocking from inside the vehicle
