automatic climate control does not have
enough time to achieve the set temperature.<
AUC Automatic recirculated-air
control/Recirculated-air mode
Switch on the desired operating
mode by pressing this button repeat-
edly:
>LEDs off: outside air flows in continuously.
>Left-hand LED on, AUC mode: a sensor
detects pollutants in the outside air. If nec-
essary, the system blocks the supply of out-
side air and recirculates the inside air. As
soon as the concentration of pollutants in
the outside air has decreased sufficiently,
the system automatically switches back to
outside air supply.
>Right-hand LED on, recirculated-air mode:
the inflow of outside air is shut off perma-
nently. The system recirculates the air
within the vehicle.
If the windows fog over in the recircu-
lated-air mode, you should switch it off
and, if necessary, increase the air flow rate.
The recirculated-air mode should not be used
over an extended period of time, otherwise the
air quality inside the car will deteriorate contin-
uously.<
Rear window defroster
The defroster switches off automati-
cally after a certain time.
Ventilation
1Knurled wheels to set any vent position
from fully open to closed
2Slide for adjusting air flow direction
Ventilation for cooling
Adjust the vent outlets to direct the flow of cool
air toward you, for instance if it has become too
hot in the car.
Draft-free ventilation
Set the vent outlets so that the air flows past
you and not straight at you.
Microfilter/activated-charcoal filter
The microfilter removes dust and pollen from
the incoming air. The activated-charcoal filter
provides additional protection by filtering gas-
eous pollutants from the outside air. Your BMW
Center replaces this combined filter during reg-
ular maintenance. A substantial reduction in air
flow indicates that the filter needs to be
replaced earlier.

into the holders on the tailgate, arrow 2.
Roadster: wind deflector*
With the convertible top open, the wind deflec-
tor keeps air movement in the passenger com-
partment to a minimum, thus providing you with
a pleasant drive, even at higher speeds.
Installation
Insert the wind deflector in its proper orienta-
tion into the guides1 provided on the rollover
bars.
Refer to the labeling on the wind deflector to
determine its proper orientation.
The wind deflector must engage firmly,
otherwise it could become detached at
higher vehicle speeds.<
The wind deflector panels2 in the rollover bars
cannot be removed.
Removal
Slide both locks inward and remove the wind
deflector.
Clothes hooks
Clothes hooks1 are located on the wind deflec-
tor panels in the rollover bars.
Do not hang heavy objects on the hooks.
If you do, they could endanger the pas-
sengers, for example during braking or evasive
maneuvers.<
Storage
For storage, e.g. to achieve a better view to the
rear when the convertible top is closed, there
are two brackets on the inside of the luggage
compartment lid/tailgate.
Insert the wind deflector into the brackets.

Driving tips
This section provides you with information
useful in dealing with specific driving and
operating conditions.

Special operating instructions
Break-in procedures
Moving parts need to be given some time until
they can interact smoothly with one another. To
ensure that your vehicle provides maximum
economy throughout a long service life, we
request that you observe the following:
Always obey all official speed limits.
Engine and differential
Up to 1,200 miles/2,000 km
Drive at varying engine and road speeds, but do
not exceed 4,500 rpm or 100 mph/160 km/h.
Refrain from using full throttle and avoid press-
ing the accelerator beyond the kickdown point.
After driving 1,200 miles/2,000 km
Engine and vehicle speeds can be gradually
increased.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac-
tion potential until an initial break-in period has
elapsed. Therefore, drive cautiously during the
first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of
approx. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and rotors. Drive cautiously during this break-in
period.
Clutch
The function of the clutch reaches its optimal
level only after a distance driven of approx.
300 miles/500 km. Shift gears carefully during
the break-in period.
After replacing components
The same break-in procedures should be
observed if any of the components mentioned
above have to be renewed in the course of the
vehicle's operating life.
Driving notes
Closing the luggage compartment lid/
tailgate
Operate the vehicle only when the lug-
gage compartment lid/tailgate is closed.
Otherwise, exhaust fumes could enter the inte-
rior of the vehicle.<
Should it be absolutely necessary to operate
the vehicle with the luggage compartment lid/
tailgate open:
1.Coupe: close both windows.
Roadster: close all windows if the convert-
ible top is closed.
2.Greatly increase the air flow from the air
conditioning or automatic climate control,
refer to page58 or61.
Hot exhaust system
In all vehicles, extremely high tempera-
tures are generated in the exhaust sys-
tem. Never remove the heat shields installed in
the area of the exhaust system, nor apply
undercoating to their surfaces. When driving,
standing at idle or parking the vehicle, take care
to avoid contact between the hot exhaust sys-
tem and flammable materials, e.g. hay, leaves,
grass, etc. Such contact could lead to a fire,
resulting in serious personal injury and property
damage.<
Mobile communications in the vehicle
BMW advises against using mobile com-
munications devices, e.g. mobile phones,
inside the vehicle without connecting them
directly to an outside antenna. Otherwise, it
