Air Volume; Air Distribution; Rear Window Defroster - BMW 2010 X3 Owner's Manual

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
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. This function is only avail-
able with the engine running.
The cooling function helps to prevent conden-
sation from forming on the windows or to
remove it quickly.
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.<
