Important safety notes
United Kingdom only: G
WARNING
When the double locks are activated, the
doors can no longer be opened from the
inside. People in the vehicle can no longer get out, e.g. in hazardous situations. There is a
risk of injury.
Therefore, do not leave any people unsuper-
vised in the vehicle, particularly children, eld-
erly people or people in need of special assis-
tance. Do not activate the double lock when
people are in the vehicle.
If the vehicle has been locked from the out-
side, the double-lock function is activated as
standard. It is then not possible to open the
doors from inside the vehicle. You can deac-
tivate the double lock function by deactivat-
ing the interior motion sensor . The doors can
then be opened from the inside after the vehi- cle has been locked from the outside. The
anti-theft alarm system is triggered if the door
is opened from the inside. Switch off the
alarm (Y page 85).

WARNING
If you leave children unattended in the vehi-
cle, they may be able to set the vehicle in
motion if, for example, they:
R release the parking brake
R shift the automatic transmission out of park
position Por shift manual transmission into
neutral
R start the engine
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the key with you and lock the vehicle. Never leave
children unattended in the vehicle. G
WARNING
If you attach heavy or large objects to the key, the key could be unintentionally turned in the
ignition lock. This could cause the engine to
be switched off. There is a risk of an accident.
Do not attach any heavy or large objects to the
key. Remove any bulky keyrings before insert-
ing the key into the ignition lock.
! Keep the key away from strong magnetic
fields. Otherwise, the remote control func-
tion could be affected.
Strong magnetic fields can occur in the
vicinity of powerful electrical installations.
Do not keep the key: R with electronic devices, e.g. a mobile
phone or another key
R with metallic objects, e.g. coins or metal
film
R inside metallic objects, e.g. a metal case
This can affect the key's functionality.
Vehicles with KEYLESS-GO start function: do not keep the key on the parcel shelf or in
the boot. Otherwise, the key may not be
detected, e.g. when starting the engine using
the Start/Stop button. 90
KeyOpening and closing

Important safety notes
G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Exhaust
gases can enter the vehicle interior if the boot
lid is open when 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 boot lid. Never drive with the boot lid
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 boot lid swings upwards when
opened. Therefore, make sure that there is sufficient clearance above the boot lid. The opening dimensions on the boot lid can
be found in the "Vehicle data" section
(Y
page 476).
i You can limit the opening angle of the
boot lid in COMAND Online or Audio 20
(see the separate operating instructions).
Do not leave the key in the boot. You could
otherwise lock yourself out.
Stow luggage or loads preferably in the boot.
Observe the loading guidelines (Y page 368). Obstacle detection with boot lid
reversing feature
Vehicles with boot lid remote closing fea- ture: the boot lid is equipped with automatic
obstacle detection with reversing function. If
a solid object blocks or restricts the boot lid
when automatically opening, this procedure
is stopped. If a solid object blocks or restricts the boot lid when automatically closing, the
boot lid opens again automatically. The auto- matic obstacle recognition with reversing
function is only an aid. It is not a substitute for
your attentiveness when opening and closing the boot lid. 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 parts of the
body are in the closing area.
If someone is trapped:
R press the Fbutton on the key, or
R press the remote operating switch on the
driver's door, or
R press the closing or locking button on the
boot lid, or
R pull the boot lid handle Boot

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 situa-
tions, for example, could lead to the boot lid opening unintentionally:
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 boot lid or
stop the procedure without using your hands. This is useful 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 about your
person. The KEYLESS-GO key must be in
the rear detection range of the vehicle.
R When making the kicking movement, make
sure that you are standing firmly on the
ground and that there is sufficient clear-
ance 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
sensors :.
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. Oth- Boot

erwise, the sensors may not function cor-
rectly.
R HANDS-FREE ACCESS does not function
when the engine is started.
R If a KEYLESS-GO key is within the rear
detection range of KEYLESS-GO, HANDS-
FREE ACCESS could be triggered. The boot
lid could thus be opened or closed unin-
tentionally, for example, if you:
- set down or lift up an object behind the
vehicle
- polish the rear of the vehicle
Do not carry the KEYLESS-GO key about
your person in such situations. This will
prevent the unintentional opening/closing
of the boot.
R Dirt caused by road salt around sensors :
may restrict functionality.
R Using HANDS-FREE ACCESS with a pros-
thetic leg may restrict functionality.
Operation X
To open/close: kick into sensor detection
range :under the bumper with your leg.
You will hear a warning tone while the boot lid is opening or closing.
X If the boot lid does not open after sev-
eral attempts: wait at least ten seconds
then kick under the bumper once again.
If you hold your foot under the bumper for too
long, the boot lid does not open or close.
Repeat the kicking movement more quickly if this occurs. To stop the opening or closing procedure:
R move your foot in sensor detection
range :under the bumper, or
R pull the handle on the outside of the boot lid
or
R press the closing button in the boot lid or
R press the Fbutton on the key
