Overview of climate control systems
General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise fog
up.
To prevent the 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 dehumidifica-
tion function
R
Activate the "Windshield defrosting" function
briefly, if required
Climate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances out of the air.
The residual heat function can only be activated
or deactivated with the ignition switched off
(Y page 135).
i
Ventilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (Y page 90). This will speed
up the cooling process and the desired inte-
rior temperature will be reached more
quickly.
If you start the engine using your smartphone,
the last selected climate control setting is reac-
tivated (Y page 142).
i
The integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants
and odors. A clogged filter reduces the
amount of air supplied to the vehicle interior.
Depending on the operating conditions and
environmental influences, the interval for
replacing the filter may be shorter than speci-
fied.
i
Vehicles with ionization of the interior
air with air filter: in addition to ionization,
the vehicle has an air filter with anti-allergenic
properties that contribute to improved air fil-
tration.
i
It is possible that under certain circumstan-
ces the residual heat function may be activa-
ted automatically an hour after the SmartKey
has been removed in order to dry the auto-
matic climate control. The vehicle is then ven-
tilated for 30 minutes.
