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 27). 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 (only vehicles
with Intelligent Light System). This prevents
oncoming traffic from being dazzled. Sym-
metrical lights do not illuminate as large an
area of the edge of the carriageway.
Vehicles with halogen or static LED
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 Intelligent Light System Before crossing the border, set the head-
lamps to symmetrical dipped beam and after
returning back to asymmetrical dipped beam
via the "Dipped-beam headlamps for driving
on the right/left" function in the on-board
computer (Y page 311).
If the headlamps are converted to symmetri-
cal dipped beam, the "motorway mode" and
"extended range foglamps" functions are not
available. Setting the exterior lighting
Setting options Exterior lighting can be set by:
R using the light switch
R using the combination switch
(Y page 137)
R adjusting the headlamp range (vehicles
with halogen headlamps only)
(Y page 136)
R using the on-board computer

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" function using the on-board
computer (Y page 311).
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
you are driving. This allows you to recognise
pedestrians, cyclists and animals.
Active: when the lights are switched on 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. It can only
be activated when the dipped-beam head-
lamps are switched on.
Active:
R if you are driving at speeds below 40 km/h
and switch on the turn signal or turn the
steering wheel
R if you are driving at speeds between
40 km/h and 70 km/h and turn the steer-
ing wheel
The cornering lamp may remain lit for a short
time, but is automatically switched off after
no more than three minutes.
Motorway mode Active:
if you are driving at a speed above
110 km/h and do not make any large steering
movements for at least 1,000 mor if you are
driving at a speed above 130 km/h 138
Exterior lightingLights and windscreen wipers

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, following activation, you are
driving 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 head-
lamps.
Partial main-beam illumination is a form of
illumination whereby the main beam is direc-
ted 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 head-
lamps.
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
traffic signs, the lights are automatically dim- med and glare for the driver caused by the
reflections is thus avoided.
The system's optical sensor is located behind
the windscreen near the overhead control
panel.
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. Exterior lighting

Adaptive Highbeam Assist Plus cannot take
into account road, weather or traffic condi-
tions. Adaptive Highbeam Assist Plus is only
an aid. You are responsible for adjusting the
vehicle's lighting to the prevailing light, visi-
bility 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 if the sensors are
obscured
