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.
!The tailgate swings upwards and to the
rear when opened. Therefore, make sure
that there is sufficient clearance above and
behind the tailgate.
The opening dimensions of the tailgate can be
found in the "Vehicle data" section
(
Ypage 415).
You can limit the opening angle of the tailgate
(
Ypage 97). 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 load-
ing guidelines (
Ypage 306).
Tailgate obstruction detection with
reversing feature
Vehicles with remote tailgate closing fea-
ture: the tailgate is equipped with automatic
obstacle recognition with reversing feature. If
a solid object blocks or restricts the tailgate
when automatically opening, this procedure
is stopped. If a solid object blocks or restricts
the tailgate when automatically closing, the
trunk lid automatically opens again slightly.
The automatic obstacle recognition with
reversing feature is only an aid. It is not a
substitute for your attentiveness when open-
ing and closing the tailgate.
GWARNING
The reversing feature does not react:
Rto soft, light and thin objects, e.g. small fin-
gers
Rover the last 1/3 in (8 mm) of the closing
movement
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 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
tailgate or
Rpull the handle on the tailgate
Vehicles with HANDS-FREE ACCESS: it is
also possible to stop the closing process by

Important safety notes
GWARNING
Parts of the body could become trapped dur-
ing automatic closing of the tailgate. More-
over, people, e.g. children, may be standing in the closing area or may enter the closing area
during the closing process. There is a risk of
injury.
Make sure that nobody is in the vicinity of the
closing area during the closing process.
Use one of the following options to stop the
closing process:
Rpress the Fbutton on the SmartKey.
Rpull or press the remote operating switch
on the driver's door.
Rpress the closing or locking button on the
tailgate.
Rpull the handle on the tailgate

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
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 tail- gate could thus be opened or closed unin-
tentionally, for example, if you:
-install or remove the ball coupling.
-couple or uncouple a trailer.
-install or remove a rear-mounted bicycle
rack.
-load/unload bicycles on/from a rear-
mounted bicycle rack.
-sit on the edge of the cargo compart-
ment.
-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 tail-
gate.
RDirt caused by road salt around sensors :
may restrict functionality.
RUsing the HANDS-FREE AC CESS with a
prosthetic leg may restrict functionality.
Operation
XTo open/close: kick into sensor detection
range :under the bumper with your foot.
Two warning tones sound while the tailgate
is opening or closing.
XIf the tailgate does not open/close after
several attempts: wait at least ten sec-
onds, using your foot kick under the
bumper again.

Important safety notes
GWARNING
Children could become trapped if they adjust
the seats, particularly when unattended.
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.
The seats can still be adjusted when there is
no SmartKey in the ignition lock.
GWARNING
When you adjust a seat, you or other vehicle
occupants could become trapped, e.g. on the seat guide rail. There is a risk of injury.
Make sure when adjusting a seat that no one
has any body parts in the sweep of the seat.
Observe the safety notes on "Air bags"
(
Ypage 48) and "Children in the Vehicle"
(
Ypage 60).
GWARNING
If the driver's seat is not engaged, it could
move unexpectedly while the vehicle is in
motion. This could cause you to lose control of the vehicle. There is a risk of an accident.
Always make sure that the driver's seat is
engaged before starting the vehicle.
GWARNING
