Switching cooling with air
dehumidification on/off
Cooling is operational when the engine is
running, and cools according to the selected
interior temperature for the vehicle. Cooling
also dehumidifies the air inside the vehicle
and, thereby, prevents the windows from
fogging up. G
WARNING
If you switch off cooling with
dehumidification, the vehicle will not be
cooled and the air not dehumidified in warm
weather conditions. The windows can mist up
faster. This could result in your no longer
being able to observe the traffic conditions
properly and you may cause an accident.
i Condensation may collect on the
underside of the vehicle when the cooler is
operating.

Useful information
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.

specialist workshops (Y page 29).Overview of climate control systems
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 13
.O ptimum
operation is only achieved if you drive with the
side windows and sliding sunroof closed.
You can also set some automatic climate
contro lfunction svia COMAND (Y page 239).i
Ventilate the vehicle for a brief period
during warm weather, e.g. using the
convenience opening feature (Y page 89).
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.
13 The residual heat function can only be activated/deactivated if the ignition is switched off. 262

Below, you can find a number of notes and
recommendations to help you use climate
control optimally.
R Activate climate control using the Ã
rocker switch. The indicator lamp in the
à 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
