All other setting options for the automatic
climate control can be found in the "Cli-
mate" menu and in the menu on the Con-
trol Display, as of page 92.
The current setting for air distribution is dis-
played on the Control Display.
A congenial climate
To use the automatic function, press the
AUTO button. Select an interior tempera-
ture you find pleasant.
The following section contains more
detailed information on the available set-
ting options.
The cooling function is only possible with
the engine running.
Automatic air distribution and supply
The AUTO program adjusts the
air distribution to the wind-
shield and side windows,
towards the upper body and footwell as
well as the air volume, while also using your
preselected temperature setting as the
basis for adjusting the interior climate to
adapt to external influences: summer, win-
ter.
The cooling function comes on automati-
cally when you select the AUTO program.
At the same time, a condensation sensor
controls the program in such a way that
window condensation is prevented as far
as possible.
Adjusting temperature
You can turn to select the
desired temperatures for the
driver and passenger sides.
The figures on the display pro-
vide a general indication of inte-rior temperature. A pleasant adjustment is
727/226. When you start the vehicle, the
system ensures that the selected tempera-
ture is achieved as quickly as possible. It
then maintains this temperature, regard-
less of the season.
Defrosting windows and removing
condensation
This program quickly removes
ice and condensation from the
windshield and front side win-
dows.
Adjusting the air volume manually
You can adjust the air volume
by turning. You can reactivate
the automatic mode for the air
volume with the AUTO button.
Switching cooling function on and off
manually
The cooling function cools and
dehumidifies the incoming air
before also reheating it as
required, according to the temperature set-
ting. Depending on the weather, the wind-
shield may fog over briefly when the engine
is started.
The cooling function comes on automati-
cally when you select the AUTO program.
Maximum cooling
This program quickly provides
maximum cooling.
The system switches to the
recirculated-air mode and the
air flows at maximum air volume only from
the vent outlets for the upper body area.
For this reason you should ensure that
these vent outlets are open before select-
ing this program.

Maintenance
The BMW Maintenance
System
The BMW Maintenance System is
designed to ensure that your vehicle will
continue to furnish consistent reliability
combined with optimal safety. The service
schedule also includes operations related
to the vehicle's comfort and convenience
features, such as replacement of the filters
for the inside air. The ultimate objective is
to ensure economical maintenance by pro-
viding the ideal service for your vehicle.
Should the day come when you decide to
sell your BMW, you will find that a complete
dealer service history is an asset of inesti-
mable value.
CBS Condition Based Service
CBS is a more advanced version of the Ser-
vice Interval Display. Sensors combine with
highly-specialized algorithms to supply
service information that reflects your vehi-
cle's actual operating conditions more pre-
cisely than ever before.
The system now provides individual dis-
plays of the times or distances remaining
until the deadlines for specific service
operations as well as legally prescribed
inspections:
>Engine oil
>Brakes: separate for front and rear
>Brake fluid
>Spark plugs >Vehicle check
>Depending on national regulations:
legally prescribed inspections.
CBS monitors both current and upcoming
service requirements. Your vehicle stores
this information continuously in the ignition
key while the vehicle is being driven. You
should therefore hand over to the BMW
Service Advisor the key you last used to
drive when you take your vehicle for ser-
vice. After accessing the data stored in the
vehicle key, your BMW Service Advisor is
able to suggest precisely the right array of
service procedures for your own individual
vehicle.
By letting you define a service and mainte-
nance regimen that reflects your own indi-
vidual requirements, Condition Based Ser-
vice builds the basis for trouble-free
driving.
You can find more detailed information on
the service requirement display on
page 66.
Make sure the date in the Control
Center is always set correctly, refer to
page 75, as otherwise the effectiveness of
Condition Based Service CBS is not
ensured. Booklet for US models and Warranty
and Service Guide Booklet for Cana-
dian models
Please consult your Service and Warranty
Information Booklet for US models and
Warranty and Service Guide Booklet for
Canadian models for additional information
on service requirements.
Have service and repair operations
performed at your BMW center.
Take the time to ensure that these service
procedures are confirmed by entries in
your vehicle's Service and Warranty Infor-
mation Booklet for US models and War-
ranty and Service Guide Booklet for Cana-
