Adjusting air volume manually
To be able to manually adjust the air volume,
switch off the AUTO program first.
Press the left side of the button to
reduce the air volume. Press the
right side of the button to increase
it.
The air volume may be reduced or the blower
may be switched off entirely to save on battery
power. The display remains the same.
Automatic recirculated-air control
AUC/Recirculated-air mode
You can respond to unpleasant odors or pollut-
ants in the immediate environment by tempo-
rarily suspending the supply of outside air. The
system then recirculates the air currently within
the vehicle.
Press the button repeatedly to
select an operating mode:
>LED off: outside air flows in continuously.
>Left-hand LED on, AUC mode: a sensor
detects pollutants in the outside air and
controls the shut-off automatically.
>Right-hand LED on, recirculated-air mode:
the supply of outside air is permanently
shut off. If the windows fog over, switch off
recirculated-air mode and increase the air
volume, if necessary. Make sure that air can
flow onto the windshield.
The recirculated-air mode should not be
used over an extended period of time;
otherwise, the air quality inside the car will dete-
riorate continuously.<
Via the button on the steering wheel
You can switch quickly between the recircu-
lated-air mode and the previous mode using a
button
on the steering wheel, refer to page11.
ALL program
Press the button.
The current temperature setting
on the driver's side is transferred to
the front passenger side.
If the temperature setting on the driver's side is
changed, the temperature on the front passen-
ger side is changed as well.
The program is switched off when the setting is
adjusted on the front passenger side or the but-
ton is pressed again.
Defrosting windows and removing
condensation
Press the button.
Quickly removes ice and conden-
sation from the windshield and
front side windows.

function.
Switching cooling function on/off
The passenger compartment can only be
cooled while the engine is running.
Press the button.
The air is cooled and dehumidified
and – depending on the tempera-
ture setting – warmed again.
Depending on the weather, the windshield may
fog up briefly when the engine is started.
Pressing the AUTO button automatically
switches on the cooling function.
Rear window defroster
Press the button.
The defroster is switched off auto-
matically after a certain time.
Depending on your vehicle's equipment, the
upper wires serve as an antenna and are not
part of the rear window defroster.
