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 38).Overview of climate control systems
Important safety notes
G
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 clogged filter replaced as soon as
possible at a qualified specialist workshop.
Climate control regulates the temperature
and the humidity in the vehicle interior and
filters undesirable substances out of the air.
Climate control is only operational when the
engine is running. The system only works
optimally when the side windows and the roof
are closed.
The residual heat function can only be
activated or deactivated with the ignition
switched off (Y page 149). i
When the weather is warm, ventilate the
vehicle for a brief period. This will speed up
the cooling process and the desired vehicle
interior temperature will be reached more
quickly.
i It is possible that the dehumidification
function of the climat econtrol system may
be activated automatically an hour after the
SmartKey has been removed. The vehicle
is then ventilated for 30 minutes to dry the
air-conditioning system. 140

automatic climate control
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 0006and
0007 buttons or the 0005button on the
control panel for the climate control. The
indicator lamps in the 0006and0007 or
0005 buttons light up.
R In automatic mode, you can also use the
000F button on the control panel for the climate control to set a climate mode
(FOCUS/MEDIUM/DIFFUSE). The
MEDIUM level is recommended.
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, since no fresh air is drawn
into the vehicle in air-recirculation mode. 142

R
Use the ZONE function to adopt the
temperature settings on the driver's side
for the front-passenger side as well.T he
indicator lamp in the 0004button goes out.
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.
i During automatic engine switch-off, the
ECO start-stop function only operates at a
reduced capacity. If you require full climate
control capacity, the ECO start/stop
function can be deactivated by pressing the
ECO button (Y page 160). Operating the climate control

General notes G
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.
i Switch on climate control primarily using
the 0006 button (Y page 144). Activating/deactivating X
Turn the SmartKey to position 2in the
ignition lock.
X To switch on: press the0006button on
the control panel for the climate control.

air dehumidification
General notes 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 prevent you from
observing the traffic conditions, thereby
causing an accident.
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.
i The refrigerant that is used by the cooling
with air dehumidification does not contain
chlorofluorocarbons and therefore does
not damage the ozone layer. Operating the climate control systems

Activating/deactivating
Example:
0007button
X To activate: press the0007button.

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. In automatic mode, the set temperature is
maintained automatically at a constant level.
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 necessary, cooling with air
dehumidification can be deactivated.
