Important safety notes
GWARNING
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.

HANDS-FREE ACCESS
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:
RCarry your KEYLESS-GO key about your per-
son. The SmartKey must be at the rear of the
82Trunk
Opening and closing

vehicle in the detection range of KEYLESS-
GO.
RWhen 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, for example on ice.
Important safety notes
GWARNING
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 make the kicking movement
only within the detection range of the 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 lid:
Rwhen using an automatic car wash
Rwhen using a power washer
Make sure that the SmartKey is at least 10 ft
(3 m) away from the vehicle.
RAlways ensure that you make the kicking
movement only within the detection range of
sensors :.
RStand at least 12 in (30 cm) away from the
rear area while doing so.
RDo not come into contact with the bumper
while making the kicking movement. Other-
wise, the sensors may not function correctly.
RHANDS-FREE ACCESS does not function dur-
ing engine start.
RDirt caused by road salt and snow build-up
around sensors :may restrict functionality.
RUsing the HANDS-FREE ACCESS with a pros-
thetic leg may restrict functionality.
RIf a KEYLESS-GO key is at the rear of the vehi-
cle in the detection range of KEYLESS-GO,
HANDS-FREE ACCESS could be triggered.
The trunk lid could thus be opened or closed
unintentionally, 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 lid.
Operation
XTo open/close: kick your foot into sensor
detection zone :below the bumper.
A warning tone will sound while the trunk lid is
opening or closing.
XIf the trunk lid does not open after several
attempts: wait at least ten seconds then
move your leg under the bumper once again.
If you hold your foot under the bumper for too
long, the trunk lid does not open or close.
Repeat the leg movement more quickly if this
occurs.
To stop the opening or closing procedure, you
have the following options:
Rkick with your foot into sensor detection
range :under the bumper
RPull the handle on the outside of the trunk lid.
RPress the closing button on the trunk lid.

GWARNING
If children operate the side windows they
could become trapped, particularly if they are left unsupervised. There is a risk of injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
Side window reversing feature
The front side windows are equipped with an
automatic reversing feature. If a solid object
blocks or restricts the upward movement of one
of the front side windows during the closing
process, the side window opens again automat-
ically. During the manual closing process, the
side window only opens again automatically
after the corresponding switch is released. How-
ever, the automatic reversing feature is only an
aid and does not relieve you of the responsibility
of paying attention when closing a side window.
GWARNING
The reversing feature does not react:
Rto soft, light and thin objects, e.g. small fin-
gers
Rover the last 1/6 in(4 mm) of the closing
movement
Rduring resetting
Rwhen closing the side window again man-
ually immediately after automatic reversing
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
someone becomes trapped, press the switch
to open the side window again.
