Air volume

You can vary the air volume in
steps 1 through 4. The heating or
cooling output is more effective
with a higher air volume.

Switching system on/off

Turn air volume rotary switch to 0. This com-
pletely shuts off the blower and air conditioning
system and stops the flow of air.
To switch on the air conditioning system, set an
arbitrary air volume.

Temperature

To increase the temperature, turn
to the right, toward red.
For a lower temperature, turn the
rotary switch counterclockwise
toward blue.

Air distribution

You can direct air to flow onto the
windows

, toward the upper

body

and into the footwell

Intermediate settings are possible.

Rear window defroster

The rear window heating switches
off automatically after a certain
amount of time. Depending on

your equipment package, the upper wires are
used as an antenna and are not part of the rear
window defroster.

Switching cooling function on/off

When the cooling function is on,
the air is cooled, dehumidified, and
then reheated depending on the

temperature setting.
Depending on the weather, the windshield may
fog over briefly when the engine is started.

Recirculated-air mode

You can respond to unpleasant
odors outside the vehicle by tem-
porarily suspending the supply of

outside air. The system then recirculates the air
currently within the vehicle.

If condensation starts to form on the
inside window surfaces during operation

in recirculated-air mode, you should switch it off
and increase the air supply as needed.
The recirculated-air mode should not be used
over a sustained period of time; otherwise, the
air quality inside the vehicle will steadily deteri-
orate.
