Important safety notes
G
WARNING
The windshield will not longer be wiped
properly if the wiper blades are worn. This
could prevent you from observing the traffic
conditions, thereby causing an accident.
Replace the

wiper blades twice a year, ideally
in spring and fall.
! 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/rear
window can scratch the glass if wiping
takes place when the windshield/rear
window is dry.
If it is necessary to switch on the windshield
wipers in dry weather conditions, always
use washer fluid when operating the
windshield wipers.
! If the windshield wipers leave smears on
the windshield/rear window after the
vehicle has been washed in an automatic
car wash, this may be due to wax or other
residue. Clean the windshield/rear window
with washer fluid after an automatic car
wash. Windshield wipers

A í Single wipe/ î To wipe the
windshield using washer fluid
X Turn the SmartKey to position 1 or 2
in the
ignition lock.
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 then damage the
windshield wiper blades or scratch the
windshield.
For this reason, you should always switch
off the windshield wipers in dry weather.
In the ° position, the appropriate wiping
frequency is set automatically according to
the intensity of the rain.
Intermittent wiping is interrupted if you stop
and open a front door. This protects people
getting into

and out of the vehicle from being
sprayed with water.
Intermittent wiping continues when all doors
are closed and:

!
To avoid damaging the wiper blades,
make sure that you touch only the wiper
arm of the wiper.
! Never open
the hood if a windshield wiper
arm has been folded away from the
windshield.
Never fold a windshield wiper arm without
a wiper blade back onto the windshield/
rear window.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release
the windshield wiper arm without a wiper
blade and it falls onto the windshield, the
windshield may be damaged by the force of
the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified
specialist workshop.

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. A clogged
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-
Benz Center 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.
The automatic climate control is only
operational when the engine is running 4
.
Optimum operation is only achieved if you
drive with the side windows and sliding
sunroof closed. i
Ventilate the vehicle for a brief period
during warm weather, e.g. using the
convenience opening feature ( Y page 69).
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. A clogged 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.

Notes on using dual-zone automatic
climate control
The following contains notes and
recommendations on optimum use of dual-
zone automatic climate control. R
Activate climate

control using the à and
Á buttons. The indicator lamps above
the à and Á buttons light 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 Operating the climate control system

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.
R At very low temperatures, the rear window
defroster is only switched on once the
vehicle interior has warmed up. Activating/deactivating climate

Important information G
WARNING
When the climate control system is
deactivated, the outside air supply and
circulation are also deactivated. Only choose
this setting for a short time. Otherwise the
windows could

fog up, impairing visibility and
endangering you and others.
i Switch on climate control primarily using
the à button ( Y page 107).
Activating/deactivating X
Turn the SmartKey to position 2 in the
ignition lock.
X To switch on:
turn

the desired position (except position 0)
(Y page 105).
X The previously selected settings come into
effect again.
X To switch off: turn control : counter-
clockwise to position 0(Y page 105). Activating/deactivating the cooling
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
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.
i The cooling with air dehumidification
function uses refrigerant R134a. This
coolant does not contain
chlorofluorocarbons, and therefore does
not damage the ozone layer.
Activating/deactivating !
If the cooling with air dehumidification
does not switch on, it is possible that the
climate control system has lost coolant.
Have the cooling with air dehumidification
checked at

a qualified specialist workshop.
X To activate: press the Á button.
