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 with a combustion engine, the
cooling with air dehumidification function is
only available when the engine is running. For hybrid vehicles, the "Cooling with air dehu-
midification" function is also available via the
electric refrigerant compressor when the
engine is not running. Optimum climate con-
trol 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 169). i
Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 108).
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. 152

Information about using
THERMOTRONIC automatic climate
control
THERMOTRONIC automatic climate
control The following contains instructions and rec-
ommendations to enable you to get the most
out of your THERMOTRONIC automatic cli-
mate control.
R Activate climate control using the Ã
rocker switch. The indicator lamp above
the à rocker switch lights up. The "Cool-
ing with air dehumidification" function is
not activated automatically in automatic
mode. If necessary, activate this function
(Y page 161).
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.
AGILITY SELECT switch You can choose between various drive pro-
grams with the AGILITY SELECT switch

air supply and air circulation are also
switched off. The windows could mist up.
Therefore, only switch off climate control
briefly.
