Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos- sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.
i Read the information on qualified special-
ist workshops: (Y page 27). Overview of climate control systems
Important safety notes
Observe the settings recommended on the
following pages. The windows could other-
wise mist up.
To prevent the windows from misting up:
R switch off climate control only briefly
R switch on air-recirculation mode only
briefly
R switch on the cooling with air dehumidifi-
cation function
R switch on the "demist windscreen" function
briefly, if required
Climate control regulates the temperature
and air humidity in the vehicle interior. The
interior filter cleans the air, thus improving
the interior climate.
For vehicles without hybrid drive, the "Cooling with air dehumidification" function is availa-
ble when the engine is running. For hybrid
vehicles, the cooling with air dehumidification function is also available via the electric
refrigerant compressor when the engine is
not running. Optimum climate control is only
achieved with the side windows and roof
closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (Y page 166). i
Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 107).
This will speed up the cooling process and
the desired interior temperature will be
reached more quickly.
i The integrated filter filters out most par-
ticles of dust and soot and completely fil-
ters out pollen. It also reduces gaseous pol-
lutants and odours. 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 this 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 blower may be acti-
vated automatically 60 minutes after the
key has been removed depending on vari-
ous factors, e.g. the outside temperature.
The vehicle is then ventilated for
30 minutes to dry the automatic climate
control. 150

AGILITY SELECT switch
You can choose between various drive pro-
grams with the AGILITY SELECT switch.
R Manual transmission (Y page 191)
R Automatic transmission (Y page 197)
If you have selected drive program E, the cli-
mate control switches to Eco mode.
In Eco mode:
R the cooling output is reduced when cooling
R when heating, the electrical heater booster
is deactivated and heat output is reduced
as a result
R the rear window heating running time is
reduced
If you have selected drive program C,Sor S+
the climate control switches to Comfort
mode. The current climate control settings
are maintained in Comfort mode.
ECO start/stop function During automatic engine switch-off, the cli-
mate control only operates at a reduced capa-
city. If you require the full climate control out-
put, you can switch off the ECO start/stop
function by pressing the ECO button
(Y page 187).
Hybrid vehicles The cooling with air dehumidification function
is available when the vehicle is operational
and the READY indicator is lit (Y page 276).
If the internal combustion engine has been
shut off automatically, the set interior tem-
perature will be maintained for a certain
period of time. Overview of climate control systems

(Y
page 157).
R Set the temperature to 22 †.
R Only use the windscreen demisting func-
tion briefly until the windscreen is clear
again.
R Only use air-recirculation mode briefly, e.g.
if there are unpleasant outside odours or
when in a tunnel. The windows could oth-
erwise mist up as no fresh air is drawn into
the vehicle in air-recirculation mode.
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 deac- tivated with the ignition switched off. The
residual heat function is deactivated when
the ignition is switched on.

Switching climate control on/off
General notes When the climate control is switched off, the
air supply and air circulation are also
switched off. The windows could mist up.
Therefore, only switch off climate control
briefly.
Switch on climate control primarily using the à rocker switch (Y page 159).
