Important safety notes
G
WARNING
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. 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, especially when braking or abruptly changing directions.
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 381).
Stow luggage or loads preferably in the luggage
compartment. Observe the loading guidelines
(Y page 299).
Do not leave the key in the luggage compart-
ment. 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 function
The tailgate is equipped with automatic obstacle
detection with reversing feature. If a solid object blocks 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 detection with reversing
function is only an aid. It is not a substitute for
your attentiveness when opening and closing
the tailgate. G
WARNING
The reversing function does not react:
R to soft, light and thin objects, e.g. small fin-
gers
R over the last 8 mm of the closing path
This means that the reversing feature cannot
prevent someone being trapped in these sit-
uations. There is a risk of injury.
When closing make sure that no body parts
are in the closing area.
If someone is trapped:
R press the Fbutton on the key 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 88
