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 Read the information on qualified
specialist workshops: (Y page 27).Overview of climate control systems
Important safety notes
Observe the settings recommended on the
following pages. The windows could
otherwise fog up.
To preven tthe windows from fogging up:
R switch off climate control only briefly
R switch on air-recirculation mode only
briefly
R switch on the cooling with air
dehumidification function
R switch on the defrost windshield function
briefly, if required
Climate control regulates the temperature
and the humidity in the vehicle interior and
filters undesirable substances out of the air.
Climate control can only be operated when
the engine is running. Optimum operation is
only achieved with the side windows and roof
closed.
The residual heat function can only be
activated or deactivated with the ignition
switched off (Y page 136).
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the
convenience opening feature (Y page 87).
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 dehumidification
function of the climate control system may
be activated automatically an hour after the
SmartKey has been removed. The vehicle
is ventilated for 30 minutes. 126

Automatic climate control The following contains notes and
recommendations on optimum use of dual-
zone automatic climate control.
R
Activate climate control using the 0004and
0005 buttons. The indicator lamps in the
0004 and0005 buttons light up.
R Set the temperature to 72 ‡ (22 †). R
Only use the "windshield 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
for the front-passenger side as well.T he
indicator lamp in the 0003button goes out. 128

Notes on using 3-zone automatic
climate control
Automatic climate control The following contains instructions and
recommendations to enable you to ge tthe
most out of your automatic climate control.
R Activate climate control using the 0004and
0005 buttons. The indicator lamps in the
0004 and0005 buttons light up.
R In automatic mode, you can also use the
000A button to adjust airflow (FOCUS/
MEDIUM/DIFFUSE). The MEDIUM level is
recommended.
R Set the temperature to 72 ‡ (22 †).
R Only use the "windshield 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
for the front-passenger side and the rear
compartmenta s well.The indicator lamp in
the 0003 button 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.
ECO start/stop function During automatic engine switch-off, the ECO
start/stop function only operates at a
reduced capacity. If you require the full
climate control output, you can switch off the
ECO start/stop function by pressing the ECO
button (Y page 146). Operating the climate control
systems
Switching climate control on/off
Points to observe before use When the climate control is switched off, the
air supply and air circulation are also
switched off. Only use this setting for a brief
period. The windows could otherwise fog up.
Only switch off climate control briefly to
prevent the windows from fogging up.
i
Switch on climate control primarily using
the 0004 button (Y page 132).
Activating/deactivating X
Turn the SmartKey to position 2in the
ignition lock (Y page 141).
X To activate: press the0004button.
The indicator lamp in the 0004button lights
up. Airflow and air distribution are set to
automatic mode.
or
X Press the 000Cbutton.
The indicator lamp in the 000Cbutton goes
out. The previously selected settings are
restored.
X To deactivate: press the000Cbutton.
The indicator lamp in the 000Cbutton lights
up. Activating/deactivating cooling with
air dehumidification
Points to observe before use 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. Only deactivate the cooling
with air dehumidification function for a short
time to prevent the windows from fogging up.
The cooling with air dehumidification function
is only available when the engine is running.
