Exterior lighting
General notes
For reasons of safety, Mercedes-Benz recom-
mends that you drive with the lights switched on even during the daytime. Therefore, your vehicle
is equipped with special daytime driving lamps.
In some countries, operation of the headlamps
varies due to legal requirements and self-
imposed obligations. 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 reg-
istered, your headlamps must be switched to
symmetrical dipped beam as soon as possible
after crossing the border (exception: vehicles
with static LED headlamps). This prevents
oncoming traffic from being dazzled. Symmetri-
cal lights do not illuminate as large an area of the edge of the carriageway.
Vehicles with static LED headlamps 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.
Vehicles with Intelligent Light System X
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 224).
If the headlamps are converted to symmetrical
dipped beam, the "motorway mode" and "exten- ded range foglamps" functions are not available. Setting the exterior lighting

Exterior lightingLights and windscreen wipers

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.
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. It 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.
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 1000 m or if you are
driving at a speed 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 thus
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 illu-
minated 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 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

Overview of climate control systems
General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise
mist up.
To prevent the windows from misting up:
R switch off climate control only briefly
R activate air-recirculation mode only briefly
R switch on "Cooling with air dehumidification"
R activate the windscreen demisting function
briefly, if required
Climate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances out of the air.
Climate control is only operational when the
engine is running. Optimum operation is only
achieved when the side windows and the roof
are closed.
The "Residual heat" function can only be activa- ted or deactivated with the ignition switched off
(Y page 132).
i Ventilate the vehicle for a brief period during
warm weather. This will speed up the cooling process and the desired interior temperaturewill be reached more quickly.
i The integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants
and odours. A clogged filter reduces the
amount of air supplied to the vehicle interior.
For this reason, you should always observe
the interval for replacing the filter, which is
specified in the Service Booklet. As this
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet.
i It is possible that the residual heat function
may be activated automatically an hour after
the key has been removed. The vehicle is then ventilated for 30 minutes to dry the automaticclimate control. Overview of climate control systems

optimally.
R Activate climate control using the Ãand
¿ buttons. The indicator lamps above the
à and¿ buttons light up.
R Vehicles with THERMOTRONIC: in automatic
mode, you can also set the climate mode
(FOCUS, MEDIUM or DIFFUSE). The MEDIUM
level is recommended.
R Set the temperature to 22 †.
R Only use the "Windscreen demisting" function
briefly until the windscreen is clear again.
R Only use air-recirculation mode briefly, e.g. if
there are unpleasant outside odours or when
in a tunnel. The windows could otherwise mist
up as no fresh air is drawn into the vehicle in air-recirculation mode.
R Use the ZONE function to adopt the temper-
ature settings on the driver's side for the
front-passenger side and the rear compart-
ment as well. The indicator lamp above the
á button goes out.
R Vehicles with THERMOTRONIC: use the resid-
ual heat function if you want to heat or venti-
late the vehicle interior when the ignition is switched off. The residual heat function can
only be activated or deactivated with the igni-
tion switched off.
R If you change the settings of the climate con-
trol system, the climate status display
appears for approximately three seconds at
the bottom of the screen in the multimedia
system display. You will see the current set-
tings of the various climate control functions.
