Luggage compartment lidOpening from the inside
*
If the luggage compartment lid has not
been locked separately, you can open it
with this button in the footwell on the
driver's side when the vehicle is
stationary.
To closeThe handle recesses in the interior trim
panel of the luggage compartment lid
(arrows) make it easier to pull the lid
down.
To avoid injuries, be sure that the
travel path of the luggage
compartment lid is clear when it is
closed, following the same precautions
as with all closing procedures.<
Operate the vehicle only when the
luggage compartment lid is
closed. Otherwise, exhaust fumes
could penetrate the interior of the
vehicle. Should it be absolutely neces-
sary to operate the vehicle with the
luggage compartment lid open:
>Close all windows. Shut the sliding/
tilt sunroof
>Sharply increase the air supply for the
air conditioning or automatic climate
control. Refer to page 85 or 88.<

Air conditioningAir supply
You can select blower speeds
from 1 to 4. The heating and
ventilation become more and
more effective as the air
supply settings are increased. In
position 0, the blower and the heater
are switched off. The outside air supply
is blocked in position 0.
Temperature
In order to increase the
temperature of the passenger
compartment, turn to the right
(red). The temperature of the
incoming air is kept constant.
Air distribution
You can direct the emerging
air toward the windows ,
toward your upper body or
into the footwell . All inter-
mediate settings are possible. In the
setting, there is a low flow of air onto
the windows to keep them free of
condensation.
Rear window defroster
When the rear window defroster
is activated, the indicator lamp
comes on. The rear window defroster
switches off automatically.
The rear window defroster auto-
matically assumes operation
within 5 minutes after the engine is
started at outside temperatures below
approx. 39 7 (+4 6).<
Air conditioning
The air is cooled and dehumidi-
fied and Ð depending on the
temperature setting Ð rewarmed.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started. Switching on the air
conditioning will reduce condensation
forming on the windows.
Condensation forms during opera-
tion of the air conditioning system,
which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<
Recirculated-air mode
You can respond to unpleasant
external odors by temporarily
suspending the supply of outside air.
The system then recirculates the air
currently within the vehicle.
If the windows should fog over in
the recirculated-air mode, switch
it off and increase the air supply as
required.<

Air conditioningDraft-free ventilationYou 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 infinitely-variable
opening and closing of the vent
outlets
2 Selector levers for airflow direction
3 Rotary dial 3 allows you to control the
temperature of the airflow from these
outlets as desired.
MicrofilterThe built-in microfilter removes dust
and pollen from the incoming air. Your
BMW center will replace it during
routine maintenance. A substantial
reduction in airflow indicates that the
filter needs to be replaced before
scheduled maintenance.
To defrost windows and remove
condensation1 Set the blower speed control for the
airflow rate to position 4
2 Turn the rotary temperature control
completely to the right (red)
3 Rotary control for air distribution to
position
4 Switch on the rear window defroster
to defrost the rear window.

Tips for pleasant drivingUse the automatic system Ð switch on
with AUTO button 7. Select the desired
interior temperature.
Detailed setting options are described
for you in the following section.Automatic air distribution
The AUTO program adjusts the
air distribution and the air
supply for you and Ð in addition to that Ð
adapts the temperature to external
influences (summer, winter) to meet
preferences you can specify.
Individual air distribution
You can cancel the AUTO
program by selecting specific
distribution patterns to suit your
own individual requirements.
While the AUTO program is then deacti-
vated, the automatic airflow control
remains in operation. The system
directs air to the windows , the upper
body and into the footwells . You
can reactivate the automatic air distri-
bution mode by selecting the AUTO
button.
Temperature
The interior temperature that
appears in the display panel is a
general figure intended for reference
purposes. We recommend 72 7
(+22 6) as a comfortable setting, even
if the air conditioning is on. When you
start the vehicle, the system ensures
that the selected temperature is
achieved as quickly as possible. It then
maintains this temperature, regardless
of the season.
Air supply
By pressing the left or right half
of the button, you can vary the
air supply. This deactivates the auto-
matic control of the air supply, AUTO
disappears from the display panel.
Nevertheless, the automatic air distri-
bution remains unchanged. You can
reactivate the automatic air distribution
mode by selecting the AUTO button.
When the lowest blower speed is set
and you press the left half of the button,
all of the displays are canceled: the
blower, heating and air conditioning are
switched off. The outside air supply is
blocked. You can reactivate the system
by pressing any button for the auto-
matic climate control.
To defrost windows and remove
condensation
This program quickly removes
ice and condensation from the
windshield and the side windows.
Air conditioning
The air is cooled and dehumidi-
fied and Ð depending on the
temperature setting Ð rewarmed.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started. Switching on the air
conditioning will reduce condensation
forming on the windows.
Condensation forms during opera-
tion of the air conditioning system,
which then exits under the vehicle.

are thus normal.<
