Overview of climat ec ontrol systems
General notes Observe the settings recommended on the fol-
lowing pages. The windows could otherwise fog
up.
To preven tt he 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-conditionin gs ystem or dual-zon ea uto-
matic climate control regulates the temperature
and the humidity of the vehicle interior and fil-
ters undesirable substances from the air.
The air-conditionin gs ystem or dual-zon ea uto-
matic climate control can only be operated
when the engin eisr unning. Optimum operation
is only achieved with the side windows and pan-
orama roof with power tilt/sliding panel closed.
If you start the engine using your smartphone,
the last selected climate control setting is reac-
tivated ( Y
page 83).
The residual heat function can only be activated
or deactivated with the ignition switched off
( Y
page 119). Always keep the ventilation flaps behind the
side trim panel in the cargo compartment clear
( Y
page 106). Otherwise the vehicle will not be
ventilated correctly.
i Ventilate the vehicle for ab rief 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 odors. Ac logged filter reduces the
amount of air supplied to the vehicle interior.
For this reason, you should alway so bserve
the interval for replacing the filter, which is
specified in the Maintenance Booklet. As it
depends on environmental conditions ,e .g.
heavy air pollution, the interval may be
shorter than stated in the Maintenance Book-
let.
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-
mat ic climate control. The vehicle is then ven-
tilated for 30 minutes.110
