especially if the vehicle is in motion. There is a
risk of poisoning.
Always switch off the engine before opening
the trunk lid. Never drive with the trunk lid
open.
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.
!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
(
Ypage 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

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.
GWARNING
The reversing feature does not react:
Rto soft, light and thin objects, e.g. small fin-
gers
Rover 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:
Rpress the Fbutton on the SmartKey, or
Rpull or press the remote operating switch
on the driver's door or
Rpress the closing or locking button on the
trunk lid, or
Rpull on the trunk lid handle

Always switch off the engine before opening
the trunk lid. Never drive with the trunk lid
open.

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.

remains open.
HANDS-FREE ACCESS
Important safety notes
GWARNING
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:
Rusing a car wash
Rusing 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:
RCarry your KEYLESS-GO key about your per-
son. The KEYLESS-GO key must be in the rear
detection range of the vehicle.
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 e.g. on ice.
RAlways ensure that you only make the kicking
movement within the detection range of sen-
sors
:.
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
when the engine is started.
RDirt caused by road salt around sensors :
may restrict functionality.
Using the HANDS-FREE ACCESS with a pros-
thetic leg may restrict functionality.
RIf 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.
