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 488).
You can limit the opening angle of the tailgate
(Y page 108).
Do not leave the key in the luggage compart- ment. You could otherwise lock yourself out.
Stow luggage or loads preferably in the lug-
gage compartment. Observe the loading
guidelines (Y page 390). Tailgate obstruction detection with
reversing function
Vehicles with remote tailgate closing fea- ture: the tailgate is equipped with automatic
obstacle recognition with a 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
tailgate automatically opens again slightly.
The automatic obstacle recognition with
reversing function is only an aid. It is not a
substitute for your attentiveness when open- ing and closing the tailgate. 104

Fluctuations in capacity will thus be avoi-

of overfilling, which can cause damage to

ponents.
! Surfaces which have come into contact
with AdBlue ®
while refilling should be
rinsed immediately with water, or remove
AdBlue ®
with a moist cloth and cold water.
If AdBlue ®
has already crystallised, use a
sponge and cold water to clean the area.
AdBlue ®
residue crystallises after a certain
amount of time and soils the affected sur-
faces.
! AdBlue ®
is not a fuel additive and must
not be added to the fuel tank. If AdBlue ®
is
added to the fuel tank, this can lead to
engine damage.
Have the AdBlue ®
tank refilled at a qualified
specialist workshop. However, you can also
top up the AdBlue ®
tank:
R at a filling station with an AdBlue ®
filling
pump
R with AdBlue ®
refill bottles
R with an AdBlue ®
refill canister
When the pump nozzle switches off automat- ically during filling at a filling pump, the
AdBlue ®
tank has been completely filled. Do
not fill the AdBlue ®
tank any further. AdBlue ®
may leak out.
To avoid transporting already opened refill
containers in the vehicle, completely empty
refill bottles or canisters when filling the
AdBlue ®
tank, if possible.
