2004 BMW 745i air filter

A congenial climate
108 Select "Individual" and confirm. The AUTO
program is deactivated.
Microfilter/activated-charcoal filter
The microfilter removes dust and pollen
from the incoming air. The activated-char-
coal filter provides additional protection by
filtering gaseous pollutants from the out-
side air. Your BMW center replaces this
combined filter as a standard part of your
scheduled maintenance.
You can select a display of more detailed
information in the Service Interval Display,
refer to page 81.

arately on the left and right sides:

Adjusting cooling
You can also set the system to
provide the desired level of
cooling by turning. We recom-
mend setting the system for
moderate cooling. When you
start the vehicle, this system ensures that
the selected setting is achieved as quickly
as possible. It then maintains this tempera-
ture, regardless of the season.
Adjusting air supply manually
You can adjust the air supply by
turning.
Maximum cooling
This program quickly provides
maximum cooling.
The system automatically switches to the
recirculated-air mode while a high-speed
stream of air simultaneously emerges from
the vent outlets. For this reason you should
ensure that these outlets are open before
selecting this program.
Switching off rear air conditioner
The air conditioner is switched
off.
Press the button again to switch back on.

Maintenance
The BMW Maintenance
System
The BMW Maintenance System is
designed to ensure that your vehicle will
continue to furnish consistent reliability
combined with optimized safety. The ser-
vice schedule also includes operations
related to the vehicle's comfort and conve-
nience features, such as replacement of
the filters for the inside air. The aim is to
optimize maintenance with regard to
reducing the cost of running the 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
Service Interval Display. Sensors combine
with highly-specialized algorithms to sup-
ply service information that reflects your
vehicle's actual operating conditions more
precisely than ever before.
The system now furnishes individual dis-
plays of the times remaining until the dead-
lines for specific service operations as well
as official state inspections:
>Engine oil
>Brakes: separate for front and rear
>Microfilter/activated-charcoal filter
>Brake fluid
>Spark plugs >Vehicle check
>Coolant
>Official state inspections.
CBS monitors both current and upcoming
service requirements. After accessing the
data stored in the vehicle's 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 main-
tenance regimen that reflects your own
individual requirements, Condition Based
Service builds the basis for trouble-free
driving.
You can find more detailed information
on the Service Interval Display on page 81.
