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
activate the "Cooling with air dehumidifica-
tion" function
R
activate the windscreen demisting function
briefly, if required
THERMOTRONIC automatic climate control reg-
ulates the temperature and the humidity in the
vehicle interior and filters undesirable substan-
ces out of the air.
THERMOTRONIC automatic climate control is
only operational when the vehicle is ready to
drive. Optimum operation is only achieved with
the side windows closed.
The residual heat function can only be activated
or deactivated with the ignition switched off
(
Y
page 122).
Always keep the ventilation flaps behind the
side panelling clear (
Y
page 106). Otherwise the
vehicle will not be ventilated correctly.
i
Ventilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (
Y
page 83). This will speed
up the cooling process and the desired inte-
rior temperature will 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
Vehicles with auxiliary heating: under
certain environmental conditions, the resid-
ual heat function may be activated automati-
cally an hour after the key has been removed
in order to dry the automatic climate control.
When the automatic climate control drying
function is active, the blue LED lamp is lit in
the rocker switch in the centre console. The
vehicle is then ventilated for 30 minutes.
Vehicles without auxiliary heating: under
certain environmental conditions, the resid-
ual heat function may be activated automati-
cally an hour after the key has been removed
in order to dry the automatic climate control.
The vehicle is then ventilated for 30 minutes.
