Important safety notes
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 trunk lid swings upwards when
opened. Therefore, make sure that there is
sufficient clearance above the trunk lid.
i You can limit the opening angle of the
trunk lid in COMAND; see the separate
operating instructions.
i The opening dimensions of the trunk lid
can be found in the "Vehicle data" section
(Y page 495).
Do not leave the SmartKey in the trunk. You
could otherwise lock yourself out.
You should preferably place luggage or loads
in the trunk. Observe the loading guidelines
(Y page 372). Obstacle recognition with trunk lid
reversing feature
On vehicles with trunk lid remote closing fea-
ture, the trunk lid is equipped with automatic obstacle recognition with reversing feature. If a solid object blocks or restricts the trunk lid
when automatically opening or closing, this
procedure is stopped. If the trunk lid is stop-
ped 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 attentive-
ness when opening and closing the trunk lid. G
WARNING
The reversing feature does not react:
R to soft, light and thin objects, e.g. small fin-
gers
R over the last 1/3 in (8 mm) of the closing
movement
This means that the reversing feature cannot
prevent someone being trapped in these sit-
uations. There is a risk of injury.
Make sure that no body parts are in close
proximity during the closing procedure. 100

TrunkOpening and closing

!
If the SmartKey is within the rear detec-
tion range of KEYLESS-GO, the following
situations, for example, could lead to the
unintentional opening of the trunk:
R using a car wash
R using a power washer
Make sure that the SmartKey is at least
10 ft (3 m) away from the vehicle.
General notes With KEYLESS-GO and HANDS-FREE
ACCESS, you can open or close the trunk 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 the kick-
ing movement within the detection range of
sensors :.
R Stand at least 12 in (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-
erwise, the sensors may not function cor-
rectly. R

behind the vehicle.
- move the charging cable through the
detection range of the sensors.
- polish the rear of the vehicle.
Do not carry the KEYLESS-GO key about
your person in these situations or in situa-
tions similar to these. This will prevent the
unintentional opening/closing of the trunk.

The charging cable and connector will only
heat up within the permissible limiting values,
provided that:
R the power supply and the charging cable
are not damaged
R the instructions for handling the charging
cable and controls on the charging cable
are observed
If the charging cable or plug get too hot, have the mains power supply checked.
Protection device against overvoltage !
Overvoltage in the mains supply may
damage the vehicle. For this reason, the
vehicle is equipped with a protection device
against overvoltage in the mains supply.
This device may be triggered during severe thunderstorms, for example, and may lead
to the building's fuse being tripped and an
interruption in the power supply. These
functions protect the vehicle. After the
building fuse is switched on again, the
charging process resumes automatically.
Following an interruption in the power sup-
ply or tripping of the building's fuse, it may take up to 10 minutes for charging to
resume automatically.
Switch on the building's fuse again after it has
been triggered. Otherwise, the charging proc-
ess cannot be continued.
General information about the charging
procedure Pay attention to the important safety notes
(Y
page 209).
If you unlock/lock the vehicle from the out-
side, the charge socket flap also unlocks/
locks.
The charge socket flap is behind the bumper
on the right-hand side below the rear lamp
cluster. Charging the high-voltage battery via
the electrical outlet
Charging cable for mains sockets Important safety notes
! Only use the charging cable to charge the
high-voltage battery. Do not use the charg-
ing cable for other purposes. It may other-
wise be damaged.
A charging cable for connection to the mains
socket is included with the vehicle. Only use
the charging cable included with the vehicle
or charging cables that have been approved
for the vehicle.
i If you use the supplied 12 A charging
cable to charge a high-voltage battery:
R the charge time increases considerably
R electrical consumption increases consid-
erably
Where possible, charge the high-voltage
battery at a charging station (Y page 216).
Only then can certified electrical energy
consumption levels be reached.
i The charging process can vary depending
on the power supply. Therefore, always
observe the local information.
i For short charge times (charging with
16A), connect the fast-charging cable to
the wallbox/charging station. You can also
use the optionally available charging cable
with the CE plug.
Information about charging from a wallbox
can be found at (Y page 215).
Information about charging at a charging sta-
tion can be found at (Y page 216).
