Important safety notes
Xenon bulbs G
DANGER
Xenon bulbs are under high voltage. If you
touch the electrical contacts of axenon bulb,
you could suffer an electric shock and be seri-
ously or even fatally injured. For this reason,
do not remove the cover of xenon bulbs.
Do not change the xenon bulbs yourself, but
have them replaced at aqualified workshop.
Bulbs and lamps are an importan taspect of
vehicle safety. You must therefore make sure
that these function correctly at all times.
Have the headlamp setting checked regularly.
LED lamps You can neither replace xenon bulbsn
or LED
bulbs. Have LED bulbsc hanged ataqualified
specialist workshop.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times.

erwise, they could damage the bulbs, for
example, and injure themselves.
Never use abulb which has been dropped.
Such abulb may break or even explode and
injure you.
Halogen bulbs are pressurised and can
explode when you change them, particularly
if they are very hot. You should therefore wear
eye protection and gloves when you are
changing them.
There are bulbs other than xenon and LED
bulbs that you cannot replace. Replace only
the bulbs listed (Y page 120). Have the bulbs
that you cannot replace yourself changed at
aq ualified specialist workshop.
If you require assistance changing bulbs, con-
sult aqualified specialist workshop.
Do not touch the glass tube of new bulbs with
your bare hands. Even minor contamination
can burn into the glass surface and reduce
the service life of the bulbs. Always use alint-
free cloth or only touch the base of the bulb
when fitting.
Only use bulbs of the correct type.
If the new bulb still does not light up, consult
aq ualified specialist workshop.

Switching the windscreen wipers on/

WARNING
The windscree nwill not longer be wiped prop-
erly if the wiper blades are worn .This could
prevent you from observing the traffic condi-
tions, thereby causing an accident. Replace
the wiper blades twice ayear, ideally in spring
and autumn.
! Do not operate the windscreen wipers
when the windscreen is dry, as this could
damage the wiper blades. Moreover, dust
that has collected on the windscreen can
scratcht he glass if wiping takes place when
the windscreen is dry.
If it is necessary to switch on the wind-
screen 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. Cleant he
windscreen with washer fluid after an auto-
matic car wash.
! Intermittent wiping with rain sensor: due
to optical influences and the windscreen
becoming dirty in dry weather conditions,
the windscreen wipers may be activated
inadvertently. This could damage the wind-
screen wiper blades or scratcht he wind-
screen.
For this reason, you should always switch
off the windscreen wipers in dry weather. Combination switch

WARNING
Observ ethe settings recommende donthe
following pages. The windows could other-
wise mist up. This may preven tyou from
observing the traffic conditions, thereby caus-
ing an accident.
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. The system only works
optimally if the side windows and the roof are
closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (Y page 132).
i Ventilate the vehicle for abrief period
during warm weather, e.g. using the con-
venienc eopening feature (Y page 89). This
will speed up the cooling process and the
desired vehicle interior temperature will be
reached more quickly.
i The integrated filter can filter out most
particles of dust and completely filters out
pollen. Aclogged 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 Servic
eBooklet .Asit
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet. 124

with air dehumidification function
Points to observe before use G
WARNING
If the "cooling with air dehumidification" func-
tion is deactivated, the air inside the vehicle
will not be cooled (during warm weather) or
dehumidified. The windows could mist up
more quickly. This may prevent you from
observing the traffic conditions, thereby caus-
ing an accident.
The cooling with air dehumidification function
is only available when the engine is running.
The air inside the vehicle is cooled and dehu-
midified according to the temperature selec-
ted.
Condensation may drip from the underside of
the vehicle when cooling mode is active. This
is normal and not asign that there is amal-
function.
i The cooling with air dehumidification
function uses refrigerant R134a. This
refrigerant does not contain chlorofluoro-
carbons, and therefore does not damage
the ozone layer. Operating the climate control system
