on the SmartKey.
You can release the button as soon as the
trunk lid starts to close.
XTo stop the closing process:
RPress the 0054button on the SmartKey.
RPress the top of the star on the trunk lid.
RPress closing button 0043or locking but-
ton 0044on the trunk lid.

the bumper with your foot.
iIf the 0054 button on the SmartKey is
pressed or HANDS-FREE ACCESS is initiated
after the closing process is stopped, the trunk
lid opens.
Vehicles with trunk lid remote closing fea-
ture and KEYLESS-GO: when all the doors are

lid and lock the vehicle. The SmartKey must be
located to the rear of the vehicle.
XPress and release locking button 0044on the
trunk lid.
If a KEYLESS-GO key is detected outside the
vehicle, the trunk lid closes and the vehicle
locks.
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,
the trunk lid opens again after it is 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 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, for example on ice.
82Trunk
Opening and closing
RAlways ensure that you only make the kicking
movement within the detection range of sen-
sors0043.
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 0043
may restrict functionality.
RUsing 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 unintentional
opening or closing of the trunk lid.
Operation
XTo open or close: kick into sensor detection
range 0043under the bumper with your foot.
A warning tone will sound while the trunk lid is
opening or closing.
XIf the trunk lid does not open or close 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 in sensor detection
range
0043under the bumper.
RPress the closing button on the trunk lid.
RPress the top of the star on the trunk lid.
RPress the 0054button on the SmartKey
If the trunk lid closing procedure has been stop-
ped:
Rmove your foot under the bumper again and
the trunk lid will open
If the trunk lid opening procedure has been
stopped:
Rmove your foot under the bumper again and
the trunk lid will close

If the reflected light from the high-beam head-
lamps or partial high-beam headlamps from traf-
fic signs is too strong, the lights are automati-

reflections is thus avoided.
The system's optical sensor is located behind
the windshield near the overhead control panel.
Important safety notes
GWARNING
Adaptive Highbeam Assist Plus does not react
to road users:
Rwho have no lights, e.g. pedestrians
Rwho have poor lighting, e.g. cyclists
Rwhose lighting is blocked, e.g. by a barrier
In very rare cases, Adaptive Highbeam Assist
Plus may not react to road users who do have
lights, or may recognize them too late. In this,
or in similar situations, the automatic high-
beam headlamps will not be deactivated or
will be activated regardless. There is a risk of
an accident.
Always carefully observe the traffic conditions
and switch off the high-beam headlamps in
good time.
Adaptive Highbeam Assist Plus cannot take into
account road, weather or traffic conditions.
Adaptive Highbeam Assist Plus is only an aid.
You are responsible for adjusting the vehicle's
lighting to the prevailing light, visibility and traf-
fic conditions.
In particular, the detection of obstacles can be
impaired if:
Rthere is poor visibility, e.g. due to fog, heavy
rain or snow
Rthere is dirt on the sensors or anything else
covering the sensors

high-beam headlamps are automatically
switched on.
If you are driving at speeds below approx-
imately 16 mph (25 km/h) or the roads are
adequately illuminated:
The partial high-beam or high-beam head-
lamps are switched off automatically. The
0057 indicator lamp on the instrument cluster
goes out. The 00CEindicator lamp on the
