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.

Information about the components and
operating principles of COMAND can be
found on (Y page 112).
The contour of the driver's seat and front-
passenger seat backrests can be individually
adjusted to provide optimum support for your
back. This is achieved by controlling the
pressure in the air chambers in the
multicontour seat.
The adjustments are made using the
COMAND display.
i When you adjust the multicontour seat,
you may hear the air being pumped in or
released.
You can adjust the following air cushions:
R seat side bolsters
R seat backrest side bolsters
R backrest curvature in the lumbar region

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.
i Please read the information on qualified
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

X
Turn the SmartKey to position 2in the
ignition lock.
X To activate: press the^rocker switch

air dehumidification
Important information The cooling with air dehumidificatio
nfunction
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 no tbe 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 241).
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.
X Consult a qualified specialist workshop. Setting climate control to automatic

WARNING
If you switch off the cooling function, the
vehicle will not be cooled when weather
conditions are warm. The windows can fog up

visibility and endanger you and others.
In automatic mode, the set temperature is
maintained automatically at a constan tlevel.
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.
