WARNING
Wiper blades are components that are subject
to wea rand tear. Replace the wipe rblades
twice a year, preferably in the spring and fall.
Otherwise the windshield will not be wiped
properly. As a result, you may not be able to
observe surrounding traffic conditions and
could cause an accident.
! Do not operate the windshield wipers
when the windshield is dry, as this could
damage the wiper blades. Moreover, dust
that has collected on the windshield can
scratch the glass if wiping takes place when
the windshield is dry.
! If the windshield wipers leave smears on
the windshield after the vehicle has been
washed in an automatic car wash, wax or
other residues may be the reason for this.
Clean the windshield using washer fluid
after washing the vehicle in an automatic
car wash. Combination switch

X Switch on the ignition.
X Turn the combination switch to the
corresponding position.
! Intermittent wiping with rain sensor: due
to optical influences and the windshield
becoming dirty in dry weather conditions,
the windshield wipers may be activated
inadvertently. This could the ndamage the
windshield wiper blades or scratch the
windshield.
For this reason, you should always switch
off the windshield wipers in dry weather.
In the 0004or0005 position, the appropriate
wiping frequency is set automatically
according to the intensity of the rain. In
the 0005 position, the rain sensor is more
sensitive than in the 0004position, causing
the windshield wipers to wipe more
frequently. Replacing the wiper blades
Important safety notes G

wipers and remove the SmartKey from the
ignition loc kbefore changing the wiper blades
(vehicles with KEYLESS-GO: make sure that

i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible. Please note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.

Important safety notes
G
WARNING
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before
its scheduled replacement interval. Aclogged
filter will reduce the air volume to the interior
and the windows could fog up, impairing
visibility and endangering you and others.
Have a blocked filter replaced at a Mercedes-
Ben zCenter as soon as possible. G
WARNING
Follow the recommended settings for heating
and cooling given on the following pages.
Otherwise, the windows could fog up,
impairing visibility and endangering you and
others.
Automatic climate control controls the
temperature and the humidity in the vehicle
interior and filters undesirable substances
from the air.
Automatic climate control is only operational
when the engine is running 16
.O ptimum
operation is only achieved if you drive with the
side windows and sliding sunroof/panorama
roof with power tilt/sliding panel closed. You can also set some automatic climate
contro
lfunction svia COMAND (Y page 269).
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the
convenience 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 Maintenance Booklet .As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Maintenance
Booklet.
i It is possible that the blower may be
activated automatically 40 minutes after
the SmartKey is removed. The vehicle is
then ventilated for 30 minutes to dry the
air-conditioning system.
16 The residual heat function can only be activated/deactivated if the ignition is switched off. 294

Notes on using climate control
Below, you can find a numbe rofnotes and
recommendations to help you use climate
control optimally.
R Activate climate control using the 0004
rocker switch. The indicator lamp in the
0004 rocker switch lights up.
R Set the temperature to 72 ‡ (22 † ).
R Only use the "defrosting" function briefly
until the windshield is clear again.
R Only use "air-recirculation" mode briefly,
e.g. if there are unpleasant outside odors
or when in a tunnel. The windows could
otherwise fog up as in air-recirculation
mode no fresh air is drawn into the vehicle.
R Use the residual heat function if you want
to heat or ventilate the vehicle interior
when the ignition is switched off. The
"residual heat" function can only be
activated or deactivated with the ignition
switched off. Operating the climate control

Activating/deactivating cooling with
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
dehumidified according to the temperature
selected. G
WARNING
If you switch off the cooling function, the
vehicle will not be cooled when weather
conditions are warm. The windows can fog up
more quickly. Window fogging may impair
visibility and endanger you and others.
Condensation may drip from the underside of
the vehicle when it is in cooling mode. This is
normal and not a sign that there is a
malfunction.
You can activate or deactivate the cooling
with air dehumidification function via
COMAND (Y page 271).
i The cooling with air dehumidification
function uses refrigerant R134a. This
coolant does not contain
chlorofluorocarbons, and therefore does
not damage the ozone layer. Problems with the cooling with air
dehumidification function If you can no longer switch on the cooling with
air dehumidification function via COMAND,
the cooling with air dehumidification function
is switched off due to a malfunction.

WARNING
If you switch off the cooling function, the
vehicle will not be cooled when weather
conditions are warm. The windows can fog up
more quickly. Window fogging may impair
visibility and endanger you and others.
In automatic mode, the set temperature is
maintained automatically at a constant level.
The system automatically regulates the
temperature of the dispensed air, the airflow
and the air distribution.
Automatic mode will achieve optimal
operation if cooling with air dehumidification
is also activated. If desired, cooling with air
dehumidification can be deactivated.
