WARNING
Follow the recommended settings for heat-
ing and cooling given on the following pages. Otherwise the windows could fog up,
impairing visibility and endangering you
and others.
The air conditioning improves the level of
comfort when driving at high outside tem-
peratures by cooling and dehumidifying
the air.
Nearly all dust particles, pollutants, are
filtered out by an integrated particle fil-
ter before outside air enters the passenger
compartment through the air distribution
system. It also operates when the air con-
ditioning is switched off and you have
switched on the blower.
The dehumidification of the air by the air
conditioner prevents the windows from
misting up when the outside air humidity
is high.
This effect can also be used to defrost the
windows. For this, make sure, in addition
to the air conditioner, that the heater is
on the maximum setting.
The air conditioner only works when:
R the ignition is switched on
R the blower is switched on
R the driver's door is closed
Maximum effectiveness is achieved if you
drive with the windows closed.
If the operating temperature of the
high‑voltage battery is too high, the
high‑voltage battery is cooled by the air
conditioner. When the air conditioner
switches on, the cooling output in the vehi-
cle's interior is reduced as a result. The
temperature in the vehicle's interior may
rise briefly.
If the air conditioner is not switched on,
the compressor of the air conditioner and
the vehicle's cooling fan are switched on
automatically. This cools the high‑voltage
battery but not the vehicle's interior. When
the high‑voltage battery reaches the nom-
inal temperature again, the air condi-
tioner switches off automatically. Air conditioning with climate control
