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 23).Overview of climate control systems
Important safety notes

WARNING
Observe the settings recommended on the
following pages. The windows could
otherwise fog up. This could preven tyou from
observing the traffic conditions, thereby
causing an accident. 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.
The automatic climate control regulates the
temperature and the humidity of the vehicle
interior and filters out undesirable
substances from the air.
Automatic climate control is only operational
when the engine is running 5
.O ptimum
operation is only achieved if you drive with the
side windows and panorama roof with power
tilt/sliding panel closed. i
Ventilate the vehicle for a brief period
during warm weather, e.g. using the
convenience opening feature (Y page 78).
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.
Since the replacement interval depends on
environmental conditions, e.g. heavy air
pollution, the interval may be shorter than
stated in the Maintenance Booklet.
5 Automatic climate control: the residual heat function can only be activated/deactivated when the ignition
is switched off. 114

recommendations on optimum use of
automatic climate control.
R Switch on the air-conditioning system by
turning control knob Aclockwise to the
desired position (except position 0).
R Set the temperature to 22 †.
R Recommendation for preventing
fogged up windows with low outside
temperatures or rain: switch¯on for
the air distribution and switch Pand
O off if possible (Y page 120). In air-
recirculation mode, switch doff
(Y page 122). Set airflow control Ato a
setting between 3 and 6 (Y page 120).R
Recommendation for rapid cooling or
heating of the vehicle interior: set airflow
control Ato a setting between 3 and 6
briefly (Y page 120).
R Recommendation for a constant
vehicle interior temperature: set airflow
control Ato a setting between 1 and 3
(Y page 120).
R Recommendation for air distribution in
the winter: setO and
¯(Y page 120).
Recommendation for air distribution in
the summer: setP orP and
¯(Y page 120).
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 unpleasan toutside odors
or when in a tunnel. The windows could Overview of climate control systems

otherwise fog up, since no fresh air is drawn
into the vehicle in air-recirculation mode.
R If you change the settings of the climate
control system, the climate status display
appears for three seconds at the bottomof
the screen in the COMAND display, see the

The following contains instructions and
recommendations to enable you to get the
most out of your automatic climate control.
R Activate climate control using the Ãand
¿ buttons .The indicator lamps in the
à and¿ buttons light up.
R Set the temperature to 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, since no fresh air is drawn
into the vehicle in air-recirculation mode.
R Use the ZONE function to adopt the
temperature settings on the driver's side Overview of climate control systems

for the front-passenger side as well. The
indicator lamp in the
ábutton goes out.
R Use the residual heatf unction if you want
to heat or ventilate th evehicle interior
when the ignition is switched off. The
"residual heat" function can only be
activated or deactivated with the ignition

Points to observe before use 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. This may preventy ou from
observing the traffic conditions, thereby
causing an accident.
The cooling with air dehumidification function
is only available with dual-zone automatic
climate control and 3-zone automatic climate
control.
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.
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. 118

The cooling with air dehumidification
function uses refrigerant R134a. This
refrigerant does not contain
chlorofluorocarbons, and therefore does
not damage the ozone layer.

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.
The automatic function is only available in
conjunction with 3-zone automatic climate
control.
In automatic mode, the set temperature is
maintained automatically at a constant level.
