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 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. Setting the exterior lighting
Setting options Exterior lighting can be set using the:

The hazard warning lamps continue to operate
even if the ignition is switched off. Adaptive Highbeam Assist
General notes You can use this function to set the headlamps
to switch automatically between dipped beam
and main beam. The system recognises vehicles
with their lights on, either approaching from the opposite direction or travelling in front of your
vehicle, and consequently switches the head-
lamps from main beam to dipped beam. Once
the system no longer detects any other vehicles, it switches on the main-beam headlamps again.
The system's optical sensor is located behind
the windscreen near the overhead control
panel. Exterior lighting

Important safety notes
G
WARNING
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
On very rare occasions, Adaptive Highbeam
Assist may fail to recognise other road users
that have lights, or may recognise them too
late. In this, or in similar situations, the auto-
matic main-beam headlamps will not be deac-
tivated or will be activated despite the pres-
ence of other road users. There is a risk of an accident.
Always carefully observe the traffic conditionsand 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 con-
ditions.
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

Important safety notes
G
WARNING
Bulbs, lamps and plug connectors can
become very hot during use. When replacing a bulb, you could burn yourself on these com-
ponents. There is a risk of injury.
Allow these components to cool down beforereplacing the bulb.
Do not use a bulb if it has been dropped or if its
glass tube has been scratched.
The bulb may explode if:
R you touch it
R it is hot
R you drop it
R you scratch it
Use bulbs only in closed lamps that have been
designed for this purpose. Fit only spare bulbs of the same type and the specified voltage.
Marks on the glass tube reduce the service life
of the bulb. Do not touch the glass tube with
your bare hands. If necessary, clean the glass
tube when cold with alcohol or spirit and rub it
off with a lint-free cloth.
Protect bulbs from moisture during operation.
Do not allow bulbs to come into contact with
liquids.
Replace only the bulbs listed (Y page 112).
Have the bulbs that you cannot change yourself
replaced at a qualified specialist workshop.
If you require assistance replacing bulbs, con-
sult a qualified specialist workshop.
If the new bulb does not light up either, consult a qualified specialist workshop.
Headlamps 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.
Vehicles with LED headlamps: the light clus-
ters of your vehicle are equipped with LED light bulbs. Do not replace your vehicle's bulbs your-
self. Contact a qualified specialist workshop
with the necessary specialist knowledge and
tools to carry out the work required. Replacing bulbs

Switching the windscreen wipers on/

! 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. Combination switch

! Vehicles with a rain sensor: if the wind-
screen becomes dirty in dry weather condi-
tions, the windscreen wipers may be activa-
ted inadvertently. This could damage the
windscreen wiper blades or scratch the wind- screen.
For this reason, you should always switch off
the windscreen wipers in dry weather.
Vehicles with a rain sensor: in the ÄorÅ
position, the appropriate wiping frequency is
automatically set according to the intensity of
the rain. In the Åposition, the rain sensor is
more sensitive than in the Äposition, caus-
ing the windscreen wiper to wipe more fre-
quently.
If the wiper blades are worn, the windscreen will
no longer be wiped properly. This could mean
you are unable to observe the traffic conditions. 114
