WARNING
The windscreen will 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 a year, 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
scratch the glass if wiping takes place when
the windscreen is dry.
! 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. 118

X Turn the key to position 1or 2in the ignition

X Turn the combination switch to the corre-
sponding position.
! 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
position, the rain sensor is more sensitive
than in the Äposition, causing the wind-
screen wiper to wipe more frequently. Replacing the wiper blades
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.
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

the wiper blades replaced by aqualified
specialist workshop, e.g. at a Mercedes-
Benz Service Centre.

air dehumidification
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 preven
tyou from
observing the traffic conditions, thereby caus-
ing an accident.
Condensation may drip from the underside of
the vehicle when THERMOTRONIC is 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.

Automatic mode will achieve optimal opera-
tion if cooling with air dehumidification is also
activated. If desired, cooling with air dehu-
midification can be deactivated. 124
