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.
The air-conditioning system/automatic
climate control controls the temperature and
the humidity of the vehicle interior and filters
undesirable substances from the air.
The air-conditioning system/automatic
climate control is only operational when the
engine is running. 7
The system only works
optimally when the side windows and the roof
are closed. i
Ventilate the vehicle for a brief period
during warm weather. 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.

system
Below, you can find a number of notes and
recommendations to help you use the air-
conditioning system optimally.
R Switch on climate control using the 0006
button. The indicator lamp in the 0006
button lights up.
R Set the temperature to 72 ‡ (22 †).
R Recommendation for air distribution in
winter: set the0018and0007 settings.
Recommendation for air distribution in
summer: set the0019setting.
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. 118

WARNING
When the climate control system is switched
off, the outside air supply and circulation are
also switched off. Only choose this setting for
a short time when the retractable hardtop
(vario-roof) is closed. Otherwise, the windows
could fog up, impairing visibility and
endangering you and others.

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.
Depending on the equipment level, the
control panel has either the 0004button or
0006 button.
i The cooling with air dehumidification
function uses refrigerant R134a. This
coolant does not contain
chlorofluorocarbons, and therefore does
not damage the ozone layer. Operating the climate control systems
