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:
1Rotary dials for opening and closing the
vents at any setting desired
2Slide 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.

Tips for pleasant driving
Use the automatic system – switch on with
AUTO button 6. Select the desired interior tem-
perature.
Detailed setting options are described for you
below.
Automatic air distribution and supply
The AUTO program assumes the
adjustment of the air distribution and
air supply for you and in addition
adapts the temperature to external
influences, summer or winter, to meet prefer-
ences you can specify.
In the AUTO program, the air conditioning
mode is also turned on at the same time.
The AUTO program functions only to a
limited extent when the convertible top is
open.<
Individual air distribution
You yourself can direct airflow onto
the windows , toward the upper
body and into the footwell . The
arrow lights up. The automatic air
supply remains unchanged. All intermediate
settings are possible. By pressing the AUTO
button, you can reactivate the air distribution.
Temperature
The interior temperature that
appears on the display panel is a gen-
eral figure intended for reference
purposes. When you start the vehi-
cle, the system ensures that the selected tem-
perature is reached as quickly as possible,
regardless of the season. It then maintains this
temperature.
Air supply/blower
Turn the rotary control to adjust the
air supply. This shuts off the auto-
matic air supply. The arrow lights up.
The automatic air distribution
remains unchanged. You can reactivate the
automatic air supply by pressing the AUTO but-
ton.When you turn the rotary control toward zero:
the blower, heating and air conditioner are
switched off, and the air supply is stopped. You
can reactivate the system by turning the control
toward the right again.
To defrost windows and remove
condensation
This program quickly removes ice
and condensation from the wind-
shield and the side windows.
Maximum cooling
Above an outside temperature of
327/06 and with the engine run-
ning, you achieve a maximum cooling
effect as quickly as possible. At the
same time, the air conditioning is turned on.
The temperature is set to the lowest possible
value. The system switches to the recirculated
air mode, and air flows at maximum blower
speed from the ventilation grills in the upper
body area only. Therefore, the air outlets must
always be open when you select this program.
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.
The air conditioning system is automatically
switched on when you use the AUTO program.
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/Automatic recirculated air
control AUC/recirculated air mode
You can respond to unpleasant
external odors or pollutants by tem-
porarily stopping the flow of outside
air. The system then recirculates the
air currently within the vehicle.

Special operating instructions
70 sure which must be exerted by the pads to
clean the rotors by brake applications is not
reached.
If the brake rotors are corroded, they will tend to
respond to braking with a pulsating effect which
even extended application will fail to cure.
Interior and exterior mirrors with
automatic dimming feature*
Two photocells in the interior rearview mirror
serve to control the interior and exterior mirrors

with automatic dimming feature. One photocell
is positioned in the mirror's lens, see arrow,
while the other is on the opposite side of the
mirror.
To ensure perfect functioning, keep the photo-
cells clean and the area between the interior
rearview mirror and the windshield free of any
obstruction like stickers, etc.
When the vehicle is parked
Condensation formed in the air conditioning
system during operation exits under the vehi-
cle. Traces of condensed water on the ground
underneath the vehicle are thus normal.
Mobile equipment in the vehicle
BMW advises against using mobile
equipment, e.g. cellular phones, inside
the vehicle without connecting them directly to
an outside antenna. Otherwise, it cannot be
ruled out that vehicle electronics and the mobile
equipment interfere with one another. In addi-
tion, it is not ensured that the radio waves emit-
ted during transmission are directed outside of
the vehicle interior.<
Cargo loading
Avoid overloading the vehicle so that the
permissible carrying capacity of the tires
is not exceeded. Otherwise, overheating and
inner damage to the tires may result. The ulti-
mate result can assume the form of a sudden air
loss.<
Determining the maximum load
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
XXX kg or YYY lbs; otherwise damage to the
vehicle and unstable driving conditions
could result.<
2.Determine the combined weight of the
driver and passenger that will be riding in
your vehicle
3.Subtract the combined weight of the driver
and passenger from XXX kilograms or YYY
pounds
4.The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the YYY amount equals
551 lbs. and there will be two 150 lbs. pas-
sengers in your vehicle, the amount of avail-
able cargo and luggage load capacity is
251 lbs.
551 lbs. minus 300 lbs. = 251 lbs.
5.Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated
in Step 4.
