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 379).
You can limit the opening angle of the tailgate
(Y page 94).
Do not leave the key in the luggage compart-
ment. If you do so, you could lock yourself out.
Stow luggage or loads preferably in the luggage
compartment. Observe the loading guidelines

Tailgate obstruction detection with
reversing function
Vehicles with remote tailgate closing:
The tailgate is equipped with automatic obstacle detection with reversing function. If a solid
object blocks or restricts the tailgate when auto-
matically opening, this process is stopped. If a
solid object blocks or restricts the tailgate when
automatically closing, the tailgate automatically opens again slightly. The automatic obstacle
detection with reversing function is only an aid.
It is not a substitute for your attention when
opening and closing the tailgate. G
WARNING
The reversing function does not react:
R to soft, light and thin objects, e.g. fingers
R over the last 8 mm of the closing path
In these situations in particular, the reversing
function cannot prevent someone being trap-
ped. 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 push the remote operating switch on
the driver's door or
R press the closing or locking button on the

Important safety notes G
WARNING
The vehicle exhaust system can become very
hot. If you use HANDS-FREE ACCESS, you
could burn yourself by touching the exhaust
system. There is a risk of injury. Always
ensure that you only make a leg movement
within the detection range of sensors.
! If the key is within the rear detection range
of KEYLESS-GO, the following situations, for
example, could lead to the unintentional
opening of the tailgate:
R using a car wash
R using a high-pressure cleaner
Make sure that the key is at least 3 m away
from the vehicle.
General notes With KEYLESS-GO and HANDS-FREE ACCESS,
you can open or close the tailgate or stop the
process without using your hands. This is useful92

if you have your hands full. To do this, make a
kicking movement under the bumper with your
foot.
Observe the following points:
R Carry your KEYLESS-GO key with you. The key
must be in the KEYLESS-GO detection range
to the rear of the vehicle.
R When making the kicking movement, make
sure that you are standing firmly on the
ground and that there is sufficient clearance
to the rear of the vehicle. You could otherwise lose your balance, e.g. on ice. R
Always ensure that you only make a kicking
movement within the detection range of sen- sors :.
R Stand at least 30 cm away from the rear area
while doing so.
R Do not come into contact with the bumper
while making the kicking movement. Other-
wise, the sensors may not function correctly.
R HANDS-FREE ACCESS does not function dur-
ing engine start.
R Dirt caused by road salt around sensors :
may restrict functionality.
Using HANDS-FREE ACCESS with a pros-
thetic leg may restrict functionality.
R If a KEYLESS-GO key is in the KEYLESS-GO
detection range to the rear of the vehicle,
HANDS-FREE ACCESS could be triggered. The tailgate could thus be opened or closed
unintentionally, for example, if you:
- fold the ball coupling in or out
- couple or uncouple a trailer
- fit or remove a rear-mounted bicycle rack
- load/unload bicycles on/from a rear-
mounted bicycle rack
- sit on the edge of the luggage compartment
- set down or lift up an object behind the
vehicle
- polish the rear of the vehicle
Do not carry the KEYLESS-GO key with you in such situations. This will prevent uninten-
tional opening or closing of the tailgate.

i The text shown in the multimedia system
depends on the language setting. The follow- ing are examples of reversing camera displays
in the multimedia system.
Important safety notes The reversing camera is only an aid. It is not a
substitute for your attention to the immediate
surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that there are no persons, animals or
objects in range while manoeuvring and parking.
The reversing camera will not function or will
function only in a limited manner:
R if the tailgate is open
