DANGER
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Exhaust
gases can enter the vehicle interior if the tail- gate is open while the engine is running, espe-cially if the vehicle is in motion. There is a risk of poisoning.
Always switch off the engine before opening
the tailgate. Never drive with the tailgate
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 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
(Y page 364).
You should preferably place luggage or loads in the cargo compartment. Observe the loading
guidelines (Y page 272).
Do not leave the SmartKey in the cargo com-
partment. You could otherwise lock yourself
out.
You can:
R close the tailgate manually from outside
R open and close the tailgate automatically
from outside
R open and close the tailgate automatically
from inside
R limit the opening angle of the tailgate
R unlock the tailgate from inside with the emer-
gency release Tailgate reversing feature
The tailgate is equipped with automatic obstacle detection with reversing feature. If a solid objectblocks or restricts the tailgate when automati-
cally opening or closing, this procedure is stop-
ped. If the tailgate is stopped during the closing procedure, it will open again automatically. The
automatic obstacle recognition with reversing
feature is only an aid. It is not a substitute for
your attentiveness when opening and closing
the tailgate. G
WARNING
The reversing feature does not respond:
R to soft, light and thin objects, e.g. fingers
R over the last 00C2in (8 mm) of the closing
movement
The reversing feature cannot prevent some-
one from becoming trapped in these situa-
tions in particular. There is a risk of injury.
Make sure that no body parts are in close
proximity during the closing procedure.
If somebody becomes trapped:
R press the 0054button on the SmartKey, or
R pull or press the remote operating switch
on the driver's door or
R press the closing or locking button on the
tailgate or
R pull the handle on the tailgate Opening and closing manually from

Important safety notes
G
WARNING
Installing an unsuitable ball coupling may
overload the trailer tow hitch and the rear
axle. This is particularly likely in the case of
longer or differently angled ball couplings.
Consequently, the driving characteristics may
be significantly impaired and the trailer may
detach. This presents the risk of an accident
or even fatal injuries!
Install only a ball coupling that adheres to the permissible dimensions and is designed for
your intended purpose for towing a trailer. Do
not make any changes to the ball coupling or the trailer tow hitch.
You will find the values approved by the manu-
facturer on the vehicle identification plates and
those for the towing vehicle under "Technical
data" (Y page 367). G
WARNING
If the ball coupling is not installed correctly or not secured with the bolt provided and the
corresponding spring cotter, the trailer may
come loose. There is a risk of an accident.
Always install and secure the ball coupling as
described. Before every journey, ensure that
the ball coupling is secured with the bolt and
the corresponding spring cotter. G
WARNING
When the vehicle/trailer combination begins
to lurch, you could lose control of it. The vehi- cle/trailer combination could even rollover.
There is a risk of an accident.
On no account should you attempt to
straighten up the vehicle/trailer combination
by increasing the speed. Reduce vehicle Towing a trailer
