G
Risk of accident
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, dirt
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. Clean the
windscreen with washer fluid after an auto-
matic car wash. Combination switch

Turn the key to position 1or 2in the ignition
lock.
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 should always 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
Risk of accident
The wiper arms could start moving 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.
Replacing the wiper blades Removing the wiper blades
X
Remove the key from the ignition lock or
turn the key to position 0(KEYLESS-GO).
X Fold the wiper arm away from the wind-
screen until it engages.
X Set the wiper blade at right angles to the
wiper arm. X
Remove the wiper blade from the retainer
on the wiper arm in the direction of the
arrow.
Fitting the wiper blades
X Slide the new wiper blade into the retainer
on the wiper arm in the opposite direction
to the arrow.
Make sure that the wiper blade slides fully
into the retainer on the wiper arm.
X Turn the wiper blade parallel to the wiper
arm.
X Fold the wiper arm back onto the wind-
screen. Problems with the windscreen wipers

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
Risk of accident
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.
Condensatio nmay drip from the underside of
the vehicle when THERMOTRONIC is in cool-
ing mode. This is normal and no tasign 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. Activating/deactivating X

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
In automatic mode, the set temperature is
maintained automatically at a constant level.
The system automatically regulates the tem-
perature of the dispensed air, the airflow and
the air distribution.
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. Adjusts the climate control settings
This function is only available with
THERMOTRONIC luxury 3-zone automatic cli-
mate control.
The climate mode setting is especially effec-
tive at high temperatures.
You can select the following climate mode
settings in automatic mode:
FOCUS High airflow; slightly cooler setting
MEDIUM Mediuma irflow; standard setting
DIFFUSE Low airflow; slightly warmer air with less of a draught 114

Risk of accident
Clear all windows of ice or snow before setting
off. Otherwise, impaired visibility could
endanger you and others.
The rear window heating has ahigh current
draw. You should therefore switch it off as
soon as the window is clear, as it only
switches off automatically after several
minutes. If the battery voltage is too low, the rear win-
dow heating may switch off.

the rear window heating is activated again
automatically. Activating/deactivating air-recircula-
tion mode
You can deactivate the flow of fresh air if
unpleasan todours are entering the vehicle
from outside. The air already inside the vehi-
cle will then be recirculated.

the same for all contro lpanels. G
Ris
kofa ccident
Only switch ove rto air-recirculation mode
