Important safety notes
Xenon bulbs G
DANGER
Xenon bulbs are under high voltage. If you
touch the electrical contacts of a xenon 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 a qualified workshop.
If your vehicle is equipped with xenon bulbs,
you can recognise this by the following: the
cone of light from the xenon bulbs moves
from the top to the bottom and back again
when you start the engine. For this to be
observed, the lights must be switched on
before starting the engine.
Bulbs 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.
Other bulbs There are bulbs other than the xenon bulbs
that you cannot replace. Replace only the
bulbs listed (Y
page 130). Have the bulbs that
you cannot replace yourself changed at a
qualified specialist workshop.
If you require assistance changing bulbs, con-
sult a qualified 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 a lint- Changing bulbs

! 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 scratch the wind-
screen.
For this reason, you shoul dalways switch
off the windscreen wipers in dry weather.
In the ÄorÅ position, the appropriate
wiping frequency is set automatically accord-
ing to the intensity of the rain. In the Å

Important safety notes G
WARNING
The wiper arms could star tmoving and cause
an injury if you leave the windscreen wipers
switched on.
Remove the key from the ignition lock before
replacing the wiper blades.
! To avoid damaging the windscreen wiper
blades, make sure that you touch only the
wiper arm of the windscreen wiper.

!
Never open the bonnet if a windscreen
wiper arm has been folded away from the
windscreen.
Never fold a windscreen wiper arm without
a wiper blade back onto the windscreen/
rear window.
Hold the windscreen wiper arm firmly when
you change the wiper blade. If you release
the windscreen wiper arm without a wiper
blade and it falls onto the windscreen, the
windscreen may be damaged by the force
of the impact.
Mercedes-Benz recommends that you have
the wiper blades replaced by aqualified
specialist workshop, e.g. at a Mercedes-
Benz Service Centre. Problems with the windscreen wipers

Useful information
i This Owner's Manual describes all models
and all standard and optional equipment
available to your vehicle at the time of pub-
lication of the Owner's Manual. Country-
specific deviations are possible. Please
note that your vehicle may not be equipped
with all features described. This also
applies to safety-relevan tsystems and
functions.

WARNING
Observe the settings recommended on the
following pages. The windows could other-
wise mis tup. This may preven tyou from
observing the traffic conditions, thereby caus-
ing an accident.
THERMATIC/THERMOTRONIC automatic cli-
mate control controls the temperature and
the humidity of the vehicle interior and filters
out undesirable substances from the air.
THERMATIC/THERMOTRONIC automatic cli-
mate control is only operational when the
engine is running 17
.O ptimum operation is
only achieved if you drive with the side win-
dows and sliding sunroof/panorama sliding
sunroof closed.
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 96). 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 Service Booklet .As it
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 func-
tion may be activated automatically an hour
after the key has been removed. The vehi-
cle is then ventilated for 30 minutes to dry
the air-conditioning system.
17 THERMOTRONIC automatic climate control: the residual heat function can only be activated/deactivated
when the ignition is switched off. 136

matic climate control
The following contains instructions and rec-
ommendations to enable you to get the most
out of your THERMOTRONIC automati ccli-
mate control.
R Activate climate control using the Ãand
¿ buttons .The indicator lamps above
the à and¿ buttons light up. You
can also set the airflow and air distribution
of the automatic climate control to one of
three levels (FOCUS/MEDIUM/DIFFUSE).
You can set the desired level using button
G.T he MEDIUM level is recommended.
R Set the temperature to 22 †.
R Only use the demisting function briefly,
until the windscreen is clear again.
R Only use the 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 tem-
perature settings on the driver's side for
the front-passenger side and the rear com-
partment as well. The indicator lamp above
the á button goes out.
R Use the residual heat function if you want
to heat or ventilate the vehicle interior
when the ignition is switched off. The resid-
ual heat function can only be activated or
deactivated with the ignition switched off. Operating the climate control system

with air dehumidification function
Important information 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.
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. Operating the climate control system

Condensation may drip from the underside of
the vehicle when THERMOTRONI
Cis in cool-
ing mode. This is normal and not a sign that
there is a malfunction.
i The cooling with air dehumidification
function uses refrigerant R134a. This cool-
ant does not contain chlorofluorocarbons,
and therefore does not damage the ozone
layer.

tor lamp in the button flashes three times or
remains off. You can no longer switch on the
cooling with air dehumidification function.
X Consult a qualified specialist workshop. Setting climate control to automatic
mode

maintained automatically at a constant level.
The system automatically regulates the tem-
perature of the dispensed air, the airflow and
