BMW x3 2004 Manual Do Utilizador

repeatedly to run through the following
control sequence:

Indicator lamps off: outside air flows
into the vehicle

Left-hand indicator lamp on – AUC
mode: the system recognizes pollutants
in the outside air and blocks the flow of
air when necessary. The system then
recirculates the air currently within the
vehicle.
Depending on the air quality, the auto-
matic system then switches back and
forth between outside air supply and
recirculation of the air within the vehicle

Right-hand indicator lamp on: the out-
side air supply into the vehicle is com-
pletely blocked. The system then recir-
culates the air currently within the
vehicle.

If condensation starts to form on the
inside window surfaces during opera-

tion in the recirculated-air mode, you
should switch it off while also increasing air
supply as required. The recirculated-air
mode should not be used over a sustained
longer period of time, as the air quality
inside the vehicle deteriorates.

Rear window defroster

When the rear window
defroster is activated,
the indicator lamp comes on.

The rear window defroster switches off
automatically.

You can have your vehicle adjusted in
such a way that the rear window

defroster switches on automatically. It is
then switched on at outside temperatures
of less than approx. +4 6/397within
5 minutes of the engine start.

Ventilation

The air vents for the upper body area can
be adjusted:

Serrated dials for opening and closing
the vent outlets through an infinitely-
variable range

Selector levers for airflow direction

Use the serrated dial 3 to adjust the
amount of cool air that is added to the
airflow emerging from the vent outlets
for the upper body

Ventilation for cooling

Adjust the vents to direct the flow of cool
air in your direction, for instance, if the inte-
rior has become too warm, etc.

Draft-free ventilation

Set the vent outlets so that the air flows
past you and is not directed straight at you.

Microfilter/activated-charcoal filter*

The built-in microfilter removes dust and
pollen from the incoming air. The activated-
charcoal filter provides additional protec-
tion by filtering gaseous pollutants from the
outside air. This combined filter is replaced
when maintenance is performed by your
BMW Sports Activity Vehicle Center. A
substantial reduction in air supply indicates
that the filter must be replaced before nor-
mal maintenance.
