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
switch on the defrost windshield function
briefly, if required
The air-conditioning system or dual-zone auto-
matic climate control regulates the tempera-
ture and the humidity of the vehicle interior
and filters undesirable substances from the
air.
The air-conditioning system or dual-zone auto-
matic climate control can only be operated
when the engine is running. Optimum opera-
tion is only achieved with the side windows
and panorama roof with power tilt/sliding
panel closed.
If you start the engine using your smartphone,
the last selected climate control setting is
reactivated (Y page 84).
The residual heat function can only be activa-
ted or deactivated with the ignition switched
off (Y page 122).
Always keep the ventilation flaps behind the
side trim panel in the cargo compartment
clear (Y page 108). Otherwise the vehicle will
not be ventilated correctly.
i
Ventilate the vehicle for a brief period dur-
ing warm weather, e.g. using the conveni-
ence opening feature (Y page 84). This will
speed up the cooling process and the
desired interior 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 pollu-
tants and odors. A clogged filter reduces the
amount of air supplied to the vehicle inte-
rior. For this reason, you should always
observe the interval for replacing the filter,
which is specified in the Maintenance Book-
let. As it depends on environmental condi-
tions, e.g. heavy air pollution, the interval
may be shorter than stated in the Mainte-
nance Booklet.
i
It is possible that under certain circum-
stances the residual heat function may be
activated automatically an hour after the
SmartKey has been removed in order to dry
the automatic climate control. The vehicle is
then ventilated for 30 minutes.
