Air distribution

You can direct airflow onto the win-
dows

, toward the upper body

and into the footwell

. All interme-

diate settings are possible.

Air supply/blower

Turn the rotary control to adjust the
air supply. Both heating and ventila-
tion become more effective as the air
supply rate is increased.

Turn the rotary control toward zero:
The blower and the heating are turned off, and
the air supply is stopped.

Temperature

In order to increase the temperature
of the passenger compartment, turn
to the right toward the red zone.

Air conditioning

The air is cooled and dehumidified
and, depending on the temperature
setting, rewarmed.
Depending on the weather, the wind-

shield may fog over briefly when the engine is
started.

Condensation forms during operation of
the air conditioning system, which then

exits under the vehicle. Traces of condensed
water on the ground underneath the vehicle are
thus normal.

Outside air/recirculated air mode

If there are unpleasant odors in the
outside air, you can temporarily block
the supply of incoming air. The sys-
tem then recirculates the air currently

within the vehicle.

If the windows fog over in the recirculated
air mode, switch this mode off and

increase the air supply as required. Do not use
the recirculated-air mode continuously over a
long period of time as this would otherwise
reduce the air quality in the interior of the vehi-
cle.

Rear window defroster

The indicator lamp lights up when
the rear window defroster is active.
The rear window defroster switches
off automatically.

Ventilation

You can adjust the blower controls for the upper
body area to obtain the optimum airflow rates
and directions for your personal requirements:
1 Rotary dials for opening and closing the

vents at any setting desired

2 Slide for adjusting airflow direction

Microfilter

The built-in microfilter removes dust and pollen
from the incoming air and in the recirculated air
mode. Your BMW center will replace this filter
during the regularly scheduled maintenance. A
substantial reduction in airflow indicates that
the filter needs to be replaced earlier.
