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
