Climate control system
Your vehicle has a deluxe automatic climate con-
trol system with 3 zones where the temperature,
air distribution, and air supply can be set sepa-
rately on the left front side, the right front side,
and in the rear.
The climate control system warms, cools and re-
moves humidity from the air in the vehicle interi-
or. It is the most effective when the windows and
panoramic glass roof* are closed. If there is a
build-up of heat inside the vehicle, ventilation
can help to speed up the cooling process.
In all heating mode functions, except for defrost,
the blower only switches to a higher speed once
the refrigerant has reached a sufficient tempera-
ture.
Pollutant filter
The pollutant filter removes pollutants such as
dust and pollen from the air.
(@) For the sake of the environment
Energy can be saved by switching off the A/C
mode.
@) Tips
—To prevent interference with the heating
and cooling output and to prevent the win-
dows from fogging over, the air intake in
front of the windshield must be free of ice,
snow, and leaves.
— Condensation from the cooling system can
drip and form a puddle of water under the
vehicle. This is normal and does not mean
there is a leak.
— The energy management system may tem-
porarily switch off certain functions, such as
the seat heating* or rear window defogger.
These systems are available again as soon as
the energy supply has been restored.
—The climate control settings are automati-
cally stored and assigned to the vehicle key
that is in use.

operate with maximum output. To reduce unnec-
essary energy usage, only use this function brief-
ly.
If you activate [A/C eco}*, the climate control sys-
tem will operate in energy-saving mode.

ing
the rear controls > fig. 97.
= Blower
You can adjust the volume of air generated by the
blower to your preference using the rocker switch
