Overview of climate control systems
General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise
mist up.
To prevent the windows from misting up:
R switch off climate control only briefly
R activate air-recirculation mode only briefly
R switch on "Cooling with air dehumidification"
R activate the windscreen demisting 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 is only operational when the
engine is running. Optimum operation is only
achieved when the side windows and the roof
are closed.
The "Residual heat" function can only be activa- ted or deactivated with the ignition switched off
(Y page 132).
i Ventilate the vehicle for a brief period during
warm weather. This will speed up the cooling process and the desired interior temperaturewill be reached more quickly.
i The integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants
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 residual heat function
may be activated automatically an hour after
the key has been removed. The vehicle is then ventilated for 30 minutes to dry the automaticclimate control. Overview of climate control systems

control
Automatic climate control Below, you can find a number of notes and rec-
ommendations to help you use climate control
optimally.
R Activate climate control using the Ãand
¿ buttons. The indicator lamps above the
à and¿ buttons light up.
R Vehicles with THERMOTRONIC: in automatic
mode, you can also set the climate mode
(FOCUS, MEDIUM or DIFFUSE). The MEDIUM
level is recommended.
R Set the temperature to 22 †.
R Only use the "Windscreen demisting" function
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 otherwise mist
up as no fresh air is drawn into the vehicle in air-recirculation mode.
R Use the ZONE function to adopt the temper-
ature settings on the driver's side for the
front-passenger side and the rear compart-
ment as well. The indicator lamp above the
á button goes out.
R Vehicles with THERMOTRONIC: use the resid-
ual heat function if you want to heat or venti-
late the vehicle interior when the ignition is switched off. The residual heat function can
only be activated or deactivated with the igni-
tion switched off.
R If you change the settings of the climate con-
trol system, the climate status display
appears for approximately three seconds at
the bottom of the screen in the multimedia
system display. You will see the current set-
tings of the various climate control functions.
ECO start/stop function During automatic engine switch-off, the climate
control 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 143). Operating the climate control system
Switching the climate control on/off
General notes When 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.

Activating/deactivating cooling with air dehumidification
General notes If you deactivate the "Cooling with air dehumidification" function, the air inside the vehicle will not
be cooled. The air inside the vehicle will also not be dehumidified. The windows can mist up more
quickly. Therefore, deactivate the "Cooling with air dehumidification" function only briefly.
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 cooling mode is active. This is normal
and not a sign that there is a malfunction.
Activating/deactivating X
To switch on: press the¿button.
