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.
The opening dimensions of the trunk lid can be
found in the "Vehicle data" section
( Y
page 394).
You can limit the opening angle of the trunk lid in
COMAND or Audio 20 (see the Digital Opera-
tor's Manual).
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 308).
Obstruction recognition with trunk lid
reversing feature Vehicles with trunk lid remote closing fea-
ture:
The trunk lid is equipped with automatic
obstruction detection with a reversing feature. If
a solid object blocks or restricts the trunk lid
when automatically opening, this procedure is
stopped. If a solid object blocks or restricts the
trunk lid when automatically closing, the trunk
lid opens again automatically. The automatic
obstruction detection with reversing feature is
only an aid. It is not a substitute for your atten-
tiveness 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.
If somebody becomes trapped: R
press the T button on the SmartKey, or R
pull or press the remote operating switch
on the driver's door or R
press the closing or locking button on the
trunk lid, or R
pull on the trunk lid handle
Vehicles with HANDS-FREE ACCESS:
It is also possible to stop the closing process by
performing a kicking movement under the rear
bumper.

Vehicles with trunk lid remote closing fea-
ture and KEYLESS-GO: when the driver's door
is closed you can simultaneously close the trunk
lid and lock the vehicle. The KEYLESS-GO key
must be in the rear detection range of the vehi-
cle. X

If KEYLESS-GO detects a SmartKey in the trunk,
the trunk lid opens again after it is closed.
If KEYLESS-GO detects a second SmartKey out-
side the vehicle, the trunk lid remains closed.
If KEYLESS-GO detects a SmartKey in the trunk
before the closing procedure starts, the trunk lid
remains open.
HANDS-FREE ACCESS
Important safety notes
G WARNING
The vehicle's exhaust system may be very hot.
You could burn yourself by touching the
exhaust system if you use HANDS-FREE
ACCESS. There is a risk of injury. Always
ensure that you only make the kicking move-
ment within the detection range of sensors.
! If the SmartKey is within the rear detection
range of KEYLESS-GO, the following situa-
tions, for example, could lead to the uninten-
tional 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 use-
ful 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 per-
son. 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 clearance
to the rear of the vehicle. You could otherwise
lose your balance e.g. on ice.
R
Always ensure that you only make the kicking
movement within the detection range of sen-
sors C . 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. Other-
wise, the sensors may not function correctly. R
HANDS-FREE ACCESS does not function
when the engine is started. R
Dirt caused by road salt around sensors C
may restrict functionality.
Using the HANDS-FREE ACCESS with a pros-
thetic leg may restrict functionality. R
If a KEYLESS-GO key is within the rear detec-
tion range of KEYLESS-GO, HANDS-FREE
ACCESS could be triggered. The trunk lid
could thus be opened or closed unintention-
ally, for example, if you: -
sit on the edge of the trunk. -
set something down or lift something up
behind the vehicle. -
polish the rear of the vehicle.
Do not carry the KEYLESS-GO key about your
person in these situations or in situations sim-
ilar to these. This will prevent the uninten-
tional opening/closing of the trunk.92

Charging cable for electrical outlets
Important safety notes
! Only use the charging cable to charge the
high-voltage battery. Do not use the charging
cable for other purposes. It may otherwise be
damaged.
A charging cable for connection to the electrical
outlet 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 consider-
ably
Where possible, charge the high-voltage bat-
tery at a charging station ( Y
page 174). Only
then can certified electrical energy consump-
tion levels be reached.
i The charging process can vary depending on
the power supply. Therefore, always observe
the local information.
