WARNING
When the double locks are activated, the
doors can no longer be opened from the
inside. People in the vehicle can no longer get out, e.g. in hazardous situations. There is a
risk of injury.
Therefore, do not leave any people unsuper-
vised in the vehicle, particularly children, eld-
erly people or people in need of special assis-
tance. Do not activate the double lock when
people are in the vehicle.
If the vehicle has been locked from the outside, the double lock function is activated as stand-
ard. It is then not possible to open the doors
from inside the vehicle. You can deactivate the
double lock function by deactivating the interior
motion sensor (Y page 62). The doors can then
be opened from the inside after the vehicle has
been locked from the outside. The anti-theft
alarm system is triggered if the door is opened
from the inside. Switch off the alarm
(Y page 60).

Important safety notes G
WARNING
The vehicle exhaust system can become very
hot. If you unlock the luggage compartment
with KEYLESS-GO, you could burn yourself by touching the exhaust system. There is a risk of
injury. Always ensure that you only make the required kicking movement within the detec-
tion range of the sensors.
! If the key is within the rear detection range
of KEYLESS-GO, the following situations, for
example, could lead to the unintentional
opening of the tailgate:
R using a car wash
R using a high-pressure cleaner
Make sure that the key is at least 3 m away
from the vehicle.
General notes Vehicles with KEYLESS-GO without carbon
package:
you can unlock the tailgate without
using your hands. This is useful if you have your hands full. To do this, make a kicking movement
under the rear 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 a kicking
movement within the detection range of sen- sors :.
R Stand at least 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 Unlocking with KEYLESS-GO does not func-
tion when the engine is started. 72

R
Dirt caused by road salt around sensors :
may restrict functionality.
Using 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, the sensors could be triggered. Therefore, the tailgate cannot beunlocked unintentionally if, for example, you:
- sit on the edge of the luggage compartment
- set down or lift up an object behind the
vehicle
- polish the rear of the vehicle
Do not carry the KEYLESS-GO key about your
person in such situations. This prevents the
tailgate from being unlocked unintentionally.
Operation X
To unlock: kick into sensor detection
range :below the bumper with your foot.
The tailgate opens slightly.
X To open: raise the tailgate.
X If the tailgate does not unlock after sev-
eral attempts: wait at least ten seconds and
then kick under the bumper once again.
If you hold your foot under the bumper for too
long, the tailgate does not unlock. Repeat the
kicking movement more quickly if this occurs. Unlocking from inside the vehicle

gases such as carbon monoxide. If the tailgate is open when the engine is running, particu-
larly if the vehicle is moving, exhaust fumes could enter the passenger compartment.

General notes
For reasons of safety, Mercedes-Benz recom-
mends that you drive with the lights switched on even during the daytime. In some countries,
operation of the headlamps varies due to legal
requirements and self-imposed obligations. Driving abroad
It is not necessary to switch your headlamps to symmetrical dipped beam when driving in coun-
tries where vehicles are driven on the opposite
side of the road to the country in which the vehi- cle is registered. Legal requirements are fulfilled
without switching the headlamps to symmetri-
cal dipped beam. Setting the exterior lighting

cally if the vehicle reaches a speed of above
10 km/h again after a full brake application. i
The hazard warning lamps continue to oper-
ate even if the ignition is switched off. Adaptive Highbeam Assist
General notes You can use this function to set the headlamps
to switch automatically between dipped beam
and main beam. The system recognises vehicles
with their lights on, either approaching from the opposite direction or travelling in front of your
vehicle, and consequently switches the head-
lamps from main beam to dipped beam.
The system automatically adapts the dipped-
beam headlamp range depending on the dis-
tance to the other vehicle. Once the system no
longer detects any other vehicles, it switches on the main-beam headlamps again.
The system's optical sensor is located behind
the windscreen near the overhead control
panel.
Important safety notes G
WARNING
Adaptive Highbeam Assist does not recognise road users:
R who have no lights, e.g. pedestrians
R who have poor lighting, e.g. cyclists
R whose lighting is blocked, e.g. by a barrier
On very rare occasions, Adaptive Highbeam
Assist may fail to recognise other road users
that have lights, or may recognise them too
late. In this, or in similar situations, the auto-
matic main-beam headlamps will not be deac-
tivated or will be activated despite the pres-
ence of other road users. There is a risk of an accident.
Always carefully observe the traffic conditions and switch off the main-beam headlamps in
good time.
Adaptive Highbeam Assist cannot take into
account road, weather or traffic conditions.
Adaptive Highbeam Assist is only an aid. You are
responsible for adjusting the vehicle's lighting
to the prevailing light, visibility and traffic con-
ditions. 90
