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
misting up.
GRisk of accident
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.
iCondensation may collect on the
underside of the vehicle when the cooler is
operating.
XSelect the climate control main menu in the
air-conditioning function bar by turning

Vehicle equipment
i This manual describes all the standard
and optional equipment of your vehicle
which was available at the time of
purchase. Country-specific differences are
possible. Bear in mind that your vehicle
may not feature all functions described
here. This also refers to safety-related
systems and functions.
Overview of climate control systems
Important safety notes
GWarning
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 clogged filter replaced as soon as
possible at an authorized Mercedes-Benz
Center.
GWarning
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 regulates 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 15
. Optimum
operation is only achieved when you drive
with the side windows and tilt/sliding sunroof
closed.
Some functions of automatic climate control
can also be set via COMAND ( Y page 234).
i
Ventilate the vehicle for a brief period
during warm weather, e.g. using the
convenience opening feature ( Y page 86).
This will speed up the cooling process and
the desired vehicle interior temperature
will be reached more quickly.
i The integrated filter can remove most
particles of dust and removes pollen
completely. 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 Service Booklet.
As it depends on environmental conditions,
e.g. heavy air pollution, the interval may be
shorter than stated in the Service Booklet.
i It is possible that the interior 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.15 The "residual heat" function can only be switched on/off if the ignition is switched off.256Overview of climate control systemsClimate control
