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
Setting options Exterior lighting can be set by:
R using the light switch

General notes The Intelligent Light System is a system that
adjusts the headlamps automatically to suit the
prevailing driving and weather conditions. It
offers advanced functions for improved illumi-
nation of the road surface, e.g. depending on the vehicle speed or weather conditions. The sys-
tem includes the active light function, corneringlight function, motorway mode and extended
range foglamps. The system is only active when it is dark.
You can activate or deactivate the "Intelligent
Light System" function using the on-board com-
puter (Y page 209). Exterior lighting
115Lights and windscreen wipers Z

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

Important safety notes
G
WARNING
Adaptive Highbeam Assist Plus does not rec-
ognise 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
In very rare cases, Adaptive Highbeam Assist
Plus may not recognise road users who do
have lights, or may recognise them too late. In this, or in similar situations, the automatic
main-beam headlamps will not be deactivated
or will be activated despite the presence of
other road users. There is a risk of an acci-
dent.
Always carefully observe the traffic conditions and switch off the main-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
restricted if there is:
R poor visibility, e.g. due to fog, heavy rain or
snow
R dirt on the sensors or if the sensors are
obscured

Interior lighting control
General notes In order to prevent the vehicle's battery from
discharging, the interior lighting functions are
automatically deactivated after some time,
unless the key is in position 2in the ignition lock.
The colour and brightness of the ambient light-
ing are set using the multimedia system
(Y page 210).
Automatic interior lighting control X
To switch on: set the switch to centre posi-
tion A.
X To switch off: set the switch to the |
position.
The interior lighting automatically switches on if you:
R unlock the vehicle
R open a door
R remove the key from the ignition lock
The interior lighting is activated for a short time
when the key is removed from the ignition lock.
You can activate this delayed switch-off using
the on-board computer (Y page 211).Replacing bulbs
The front and rear lamps of your vehicle are
equipped with LED bulbs. Do not replace the
bulbs yourself. Contact a qualified specialist
workshop, which has the necessary specialist
knowledge and tools to carry out the work
required.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times. Have
the headlamp setting checked regularly. Windscreen wipers
Switching the windscreen wipers on/
off
! Do not operate the windscreen wipers when
the windscreen is dry, as this could damage
the wiper blades. Moreover, dust that has col- lected on the windscreen can scratch the glass if wiping takes place when the wind-
screen is dry.
If it is necessary to switch on the windscreen
wipers in dry weather conditions, always
operate them using washer fluid.
! If the windscreen wipers leave smears on
the windscreen after the vehicle has been
washed in an automatic car wash, this may be
due to wax or other residue. Clean the wind-
screen with washer fluid after an automatic
car wash.
! Intermittent wiping with rain sensor: due to
optical influences and the windscreen becom- ing dirty in dry weather conditions, the wind-
screen wipers may be activated inadvertently.
This could damage the windscreen wiper
blades or scratch the windscreen.
For this reason, you should always switch off
the windscreen wipers in dry weather. Combination switch
