DoorsOpening and closing

If a key with KEYLESS-GO is detected in the
boot, the boot lid opens again after it is closed.
It does not lock. HANDS-FREE ACCESS
Important safety notes G
WARNING
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 only make a leg movement
within the detection range of sensors.
! If the key is within the rear detection range
of KEYLESS-GO, the following situations, for
example, could lead to the boot lid opening
unintentionally:
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 With KEYLESS-GO and HANDS-FREE ACCESS,
you can open or close the boot 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:
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 HANDS-FREE ACCESS does not function
when the engine is started.
R Dirt caused by road salt around sensors :
may restrict functionality.
R 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, HANDS-FREE
ACCESS could be triggered. The boot lid could thus be opened or closed unintentionally, for
example, if you:
- sit on the edge of the boot
- 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 will prevent the
unintentional opening/closing of the boot. Boot

Exterior lighting
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
Symmetrical dipped-beam headlamps If your journey takes you to countries where
vehicles are driven on the opposite side of the
road to the country in which the vehicle is reg-
istered, your headlamps must be switched to
symmetrical dipped beam. This prevents
oncoming traffic from being dazzled. Symmetri-
cal lights do not illuminate as large an area of the edge of the carriageway.
Convert the headlamps as close to the border aspossible before driving in these countries
(Y page 210).
Asymmetrical dipped-beam headlamps Convert the headlamps back to asymmetrical
dipped beam as soon as possible after crossing
the border (Y page 210).
If the headlamps are converted to symmetrical
dipped beam, the "motorway mode" and "exten-
ded range foglamps" functions (Intelligent Light
System) are not available. Setting the exterior lighting

Active light function
The active light function is a system that moves
the headlamps according to the steering move-
ments of the front wheels. In this way, relevant
areas remain illuminated while you are driving.
This allows you to recognise pedestrians,
cyclists and animals.
Active: when the lights are switched on.
Vehicles with Lane Keeping Assist: the active
light function evaluates the course of the lane in which you are driving and adjusts the light in
advance.
Cornering light function The cornering light function improves the illu-
mination of the road over a wide angle in the
direction you are turning, enabling better visi-
bility in tight bends, for example. The cornering
light function can only be activated when the
dipped-beam headlamps are switched on.
Active:
R if you are driving at speeds below 40 km/h
and switch on the turn signal or turn the steer-
ing wheel
R if you are driving at speeds between 40 km/h
and 70 km/h and turn the steering wheel
The cornering light function may remain lit for a short time, but is automatically switched off
after no more than three minutes.
Cornering light function with roundabout
function:
The cornering light function is activated on both
sides before entering a roundabout through an
evaluation of the current GPS position of the
vehicle. It remains active until after the vehicle
has left the roundabout. In this way, pedestrians crossing the road, for example, are illuminated
by your vehicle in good time.
Motorway mode Motorway mode increases the range of the
beam.
Active:
R
if you are driving at speeds above 110 km/h
and do not make any large steering move-
ments for at least 1,000 m
R if you are driving at speeds above 130 km/h
Not active: if you are driving at speeds below
80 km/h following activation. Extended range foglamps The extended range foglamps reduce the glare
experienced by the driver and improve the illu-
mination of the edge of the carriageway.
Active: if you are driving at speeds below
70 km/h and you switch on the rear foglamp.
Not active: if, following activation, you are driv-
ing at speeds above 100 km/h or if you switch
off the rear foglamp. Adaptive Highbeam Assist Plus
General notes With Adaptive Highbeam Assist Plus, you can
automatically switch between dipped-beam,
partial main-beam and main-beam headlamps.
Partial main-beam illumination is a form of illu-
mination whereby the main beam is directed
past other road users. Other road users are kept
out of the main-beam. This prevents glare. If
there is a vehicle in front, for example, the main- beam headlamps illuminate the areas to its right
and left, and the vehicle in front is illuminated by
the dipped-beam headlamps.
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.
If the main-beam or partial main-beam head-
lamps are causing too much reflection from traf- fic signs, the lights are automatically dimmed
and glare for the driver caused by the reflectionsis thus avoided.
The system's optical sensor is located behind
the windscreen near the overhead control
panel.
Vehicles with drive program S+(Sport Plus): the
speed at which Adaptive Highbeam Assist Plus
switches between full beam and dipped beam is
increased when the drive program is switched
on. 116
