Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos-
sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.

ist workshops: ( Y page 24).
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 coun-
tries, operation of the headlamps varies due
to legal requirements and self-imposed obli-
gations.
Driving abroad
General notes
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
registered, your headlamps must be switched
to symmetrical dipped beam as soon as pos-
sible after crossing the border (exception:
vehicles with halogen headlamps). This pre-
vents oncoming traffic from being dazzled.
Symmetrical lights do not illuminate as large
an area of the edge of the carriageway.
Vehicles with halogen headlamps
It is not necessary to switch your headlamps
to symmetrical dipped beam when driving in
countries where vehicles are driven on the
opposite side of the road to the country in
which the vehicle is registered. Legal require-
ments are fulfilled without switching the
headlamps to symmetrical dipped beam.
Vehicles with bi-xenon headlampsXTurn protective cap : anti-clockwise and
remove it.XPush switchover lever ; down.XInsert protective cap : and turn it clock-
wise.
Convert the headlamps back to asymmetrical
dipped beam as soon as possible after return-
ing across the border.
Vehicles with Intelligent Light System
XBefore crossing the border, set the head-
lamps to symmetrical dipped beam and
after returning back to asymmetrical
dipped beam via the "Dipped-beam head-
lamps for driving on the right/left" function
in the on-board computer ( Y page 221).
If the headlamps are converted to symmetri-
cal dipped beam, the "motorway mode" and
"extended range foglamps" functions are not
available.

headlamp cleaning system is reset and count-
ing is resumed from 0.
Intelligent Light System
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 illu-
mination of the road surface, e.g. depending
on the vehicle speed or weather conditions.
The system includes the active light function,
cornering light 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" using the on-board computer
( Y page 221).
Active light function
The active light function is a system that
moves the headlamps according to the steer-
ing movements of the front wheels. In this
way, relevant areas remain illuminated while
driving. This allows you to recognise pedes-
trians, cyclists and animals.
Active: when the lights are switched on.
110Exterior lightingLights and windscreen wipers
ProCarManuals.com

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 vis-
ibility in tight bends, for example. The corner-
ing 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 the turn signal is activated or
the steering wheel is turned.
R if you are driving at speeds between
40 km/h and 70 km/h and turn the steer-
ing wheel.
Not active: if you are driving at speeds above
40 km/h or switch off the turn signal or turn
the steering wheel to the straight-ahead posi-
tion.
The cornering lamp may remain lit for a short
time, but is automatically switched off after
no more than three minutes.
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 steer-
ing movements for 1000 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 illumination of the edge of the carriage-
way.
Active: if you are driving at speeds below
70 km/h and you switch on the rear foglamp.
Not active: if you are driving at speeds above
100 km/h or if you switch off the rear foglamp
following activation.
Adaptive Highbeam Assist
Important safety notes
GWARNING
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
Exterior lighting111Lights and windscreen wipersZProCarManuals.com

In very rare cases, Adaptive Highbeam Assist
recognises road users too late or not at all. In
this, or in similar situations, the automatic
main-beam headlamps will not be deactivated
or activated regardless. 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 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 the sensors are
obscured
General notes
You can use this function to set the head-
lamps to change between dipped beam and
main beam automatically. The system recog-
nises vehicles with their lights on, either
approaching from the opposite direction or
travelling in front of your vehicle, and conse-
quently switches the headlamps 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 reac-
tivates the main-beam headlamps.
The system's optical sensor is located behind
the windscreen near the overhead control
panel.
