gases such as carbon monoxide. Exhaust
gases can enter the vehicle interior if the
trunk lid/tailgate is open when the engine is
running, especially if the vehicle is in motion.
There is a risk of poisoning.
Always switch off the engine before opening
the trunk lid/tailgate. Never drive with the
trunk lid/tailgate open.
!The trunk lid/tailgate swings upwards
and to the rear when opened. Therefore,
make sure that there is sufficient clearance
above and behind the trunk lid/tailgate.

Trunk lid/tailgate reversing feature
The trunk lid/tailgate is equipped with an
automatic reversing feature. It reacts if a solid
object obstructs or restricts the trunk lid/
tailgate during the closing procedure. The trunk lid/tailgate opens again automatically.
The automatic reversing feature is only an aid
and is not a substitute for your attentiveness to the trunk lid/tailgate while it is closing.
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

Sedan: on vehicles with the trunk lid remote
closing feature, you can close the trunk lid
automatically. For vehicles with trunk lid
remote closing feature and KEYLESS-GO: you
can simultaneously close the trunk lid and
lock the vehicle.
Wagon: for vehicles with KEYLESS-GO, you

The trunk lid/tailgate closes.
If all the doors are closed, the vehicle locks.
iIf KEYLESS-GO detects a SmartKey in the
trunk/cargo compartment, the trunk lid/
tailgate opens again after it is closed.
If KEYLESS-GO detects a second SmartKey
outside the vehicle, the trunk lid/tailgate
remains closed.
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 key is within the rear detection
range of KEYLESS-GO, situations such as
the following could lead to the uninten-
tional opening of the trunk lid/tailgate:
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
Sedan: with KEYLESS-GO and HANDS-FREE
ACCESS, you can open or close the trunk lid
or stop the closing procedure without using
your hands.
Wagon: with KEYLESS-GO and HANDS-FREE
ACCESS, you can open or close the tailgate 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:
RCarry your KEYLESS-GO key about your
person. 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 clear-
ance to the rear of the vehicle. You could
otherwise lose your balance e.g. on ice.
Trunk/cargo compartment99

Z
Page 102 of 350

(Example: Sedan)
RAlways ensure that you only make the kick-ing movement 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. Oth-
erwise, the sensors may not function cor-
rectly.
RHANDS-FREE ACCESS does not function
when the engine is started.
RIf a KEYLESS-GO key is within the rear
detection range of KEYLESS-GO, HAND-
FREE ACCESS could be triggered. For this
reason, the trunk lid/tailgate could open or
close unintentionally, e.g. if you:
-sit down on the edge of the trunk/edge
of the cargo compartment.
-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 situa-
tions similar to these. You can thus avoid
unintentionally opening or closing the trunk
lid/tailgate.
RDirt caused by road salt around sensors :
may restrict functionality.
RUsing the HANDS-FREE ACCESS with a
prosthetic leg may restrict functionality.
