service schedule BMW 645CI COUPE 2004 E63 Owner's Manual

A congenial climate
92 climate control is optimized for driving with
the convertible top open. In addition, the air
supply is increased as the speed increases.
If the convertible program has been
selected, it is automatically active every
time the top is opened.
The effect of the convertible program
can be greatly enhanced if the wind
deflector is fitted.<
Ventilation
You can use the serrated dials 1 to open
and close the vent outlets through an infi-
nitely-variable range, while the levers 2
allow you to adjust the airflow direction.
Do not drop any foreign bodies into
the vent outlets, as otherwise these
could be catapulted outwards and lead to
injuries.<
Ventilation for cooling
Adjust the vent outlets to direct the flow of
cool air in your direction, for instance, if the
interior has become too warm, etc.
Draft-free ventilation
Set the vent outlets so that the air flows
past you and is not directed straight at you.
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 requirement dis-
play, refer to page 65.
Independent ventilation
The independent ventilation blows air into
the passenger compartment to lower inte-
rior temperatures.
The independent ventilation is controlled
using the Control Center. You can set two
different times for the system to start.
The independent ventilation remains on for
30 minutes. It can also be switched on and
off directly. Since the system uses a sub-
stantial amount of electrical current, you
should refrain from activating it twice in
succession without allowing the battery to
be recharged in normal operation between
use.
The independent ventilation is ready for
use at any outside temperature up to igni-
tion key position 1.
The air emerges through the upper body
region vent outlets in the instrument panel.
These vent outlets must be open for the
system to operate.
Switching on and off directly

2.Select "Ventilation" and press the con-
troller

Maintenance
The BMW maintenance
system
The BMW maintenance system supports
the preservation of the traffic and operating
safety of your BMW. The service schedule
also includes operations related to the
vehicle's comfort and convenience fea-
tures, such as replacement of the filters for
the inside air. The ultimate objective is to
ensure economical maintenance by provid-
ing 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
Sensors and special algorithms take the
different driving conditions of your BMW
into account. Condition Based Service
uses this to determine the current and
future maintenance requirement. By letting
you define a service and maintenance reg-
imen that reflects your own individual
requirements, the system builds the basis
for trouble-free driving.
The service requirement display, refer to
page 65, individually displays the time or
distance remaining for selected mainte-
nance work and any legally required inter-
vals:
>Engine oil
>Brakes, front and rear separately
>Microfilter/activated-charcoal filter>Brake fluid
>Spark plugs
>Vehicle check
>Legally required tests depending on
local regulations.
Your vehicle stores this information contin-
uously in the master key while the vehicle is
being driven. After accessing the data
stored in the master key, your BMW Ser-
vice Advisor can suggest precisely the right
array of service procedures for your own
individual vehicle. You should therefore
hand over to the BMW Service Advisor the
key you last used to drive when you take
your vehicle for service.
Make sure the date in the Control
Center is always set correctly, refer to
page 74, as otherwise the effectiveness of
CBS Condition Based Service is not
ensured.<
