XMake sure that the doors and the tailgate
are locked.
XCarefully press the protective cap onto the
lock cylinder until it engages and is seated
firmly. Do not pull the door handle when
doing so.
If you lock the vehicle as described above, the
fuel filler flap is not locked. The anti-theft
alarm system is not armed.
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

Vehicle occupants could be struck in the
event of sudden braking or an accident, for
instance, if you:
Rtransport other heavy or sharp-edged
objects in the skibag
Rdo not secure the skibag with the lashing
straps
There is a risk of accident and injury.
Store only skis in the skibag. Always secure
the skibag with the lashing straps so that it
cannot move around.
A maximum of four pairs of skis or two snow-
boards can be transported in the ski and
snowboard bag.
Securing the ski/snowboard bag in the
cargo compartment
XFold the middle rear seat backrest forwards
(
Ypage 309).
XSlide the ski and snowboard bag between
the two outside rear seat backrests. Ensure
that the wheels of the ski/snowboard bag
are in the cargo compartment.
XOpen the ski/snowboard bag with zip :
and place the skis or snowboards inside it.
XClose the ski and snowboard bag.

Important safety notes
GWARNING
If the rear bench seat/rear seat and seat
backrest are not engaged they could fold for-
wards, e.g. when braking suddenly or in the
event of an accident.
RThe vehicle occupant would thereby be
pushed into the seat belt by the rear bench
seat/rear seat or by the seat backrest. The
seat belt can no longer offer the intended
level of protection and could even cause
injuries.
RObjects or loads in the trunk/cargo com-
partment cannot be restrained by the seat
backrest.
There is an increased risk of injury.
Before every trip, make sure that the seat
backrests and the rear bench seat/rear seat
are engaged.
