2006 BMW 325CI air filter

93
Draft-free ventilationYou can adjust the blower controls for
the upper body area to obtain the opti-
mum airflow rates and directions for
your personal requirements:
1Rotary dials for infinitely variable
opening and closing of the vent out-
lets
2Levers for airflow direction
3With the rotary dial, you can add
more or less cool air to the air coming
from the outlets for the upper body
area:
>Turn toward blue – cooler.
>Turn toward red – warmer.
MicrofilterThe built-in microfilter removes dust
and pollen from the incoming air. Your
BMW center will replace it during rou-
tine maintenance. A substantial reduc-
tion in airflow indicates that the filter
needs to be replaced before scheduled
maintenance.
To defrost windows and remove
condensation1. Set the blower speed rotary control
for the airflow rate to position 4
2. Turn the rotary temperature control
completely to the right to the red
zone
3. Turn the rotary control for air distri-
bution to position
4. Switch on the rear window defroster
to defrost the rear window.

Microfilter/activated-charcoal
filterThe built-in microfilter removes dust
and pollen from the incoming air. The
activated-charcoal filter provides addi-
tional protection by filtering gaseous
pollutants from the outside air. Your
BMW center replaces this combined fil-
ter as a standard part of your scheduled
maintenance. A substantial reduction in
airflow indicates that the filter needs to
be replaced before scheduled mainte-
nance.
Roller sun blind*To activate, press the button briefly
with the ignition key in position 1 or
higher.
The illustration depicts the arrangement
of the buttons if the vehicle is fully
equipped. The arrangement may vary,
depending on the equipment actually
installed.

130Maintenance
BMW Maintenance SystemThe BMW Maintenance System helps
maintain your vehicle's road safety and
operational safety. Comfort-related
aspects, such as the timely change of
filters for the air inside the vehicle, are
taken into consideration. The goal is to
optimize maintenance with respect to
low total cost of ownership.
If you should sell your BMW one day,
consistent service and maintenance will
prove to your advantage.
Service interval displayThe service interval display shows you
when an oil service, an inspection –
always alternating between I and II – or
a brake fluid change is due. The special
feature is that the service intervals are
calculated according to your BMW's
individual driving conditions instead of
from fixed mileage increments.
The technology developed for this
takes your personal driving style into
account, as well as your BMW's driving
conditions. After all, short-distance
driving, i.e. frequent cold starts, or driv-
ing off at high engine speeds, affects
your BMW differently from long-dis-
tance driving with the engine at consis-
tent operating temperature.
Special feature regarding engine
oil changeThe calculation of the service intervals
covers practically every kind of operat-
ing situation. If you drive very rarely,
however, you should have the oil
changed at least every two years, since
engine oil deteriorates over time
regardless of use.Service and Warranty Information

maintenance intervals and procedures,
please refer to the Service and War-
ranty Information Booklet for US mod-
els, or the Warranty and Service Guide
Booklet for Canadian models.
As a precaution against rust, it is advis-
able to have the body checked for dam-
age from rocks or gravel at the same
time, depending upon operating condi-
tions.

License plate lamps5 watt bulb
1. Place a screwdriver in the slot and
press toward the left to release the
lens
2. Replace the bulb.Light-emitting diodesLight-emitting diodes (LEDs) installed
behind translucent lenses serve as the
light sources for many of the controls
and displays in your vehicle. These
light-emitting diodes are related to con-
ventional lasers, and legislation defines
them as light-emitting diodes, Class 1.
Do not remove the protective lens,
and avoid staring directly at the
unfiltered beam for several hours, as
inflammation of the retina could
result.<
Changing a wheel
Safety precautions in the event of
a flat tire or wheel change:
Stop the vehicle as far as possible from
passing traffic. Park on a firm, flat sur-
face. Switch on the hazard warning
flashers. Turn the steering wheel to the
straight-ahead position and engage the
steering lock. Shift into 1st or Reverse,
or if you have an automatic transmis-
sion position the selector lever in Park,
and engage the parking brake.
All passengers should be outside the
vehicle and well away from your imme-
diate working area, behind a guardrail,
for example.
If a warning triangle or portable hazard
warning lamp is available, set it up on
the roadside at an appropriate distance
from the rear of the vehicle. Comply
with all local safety guidelines and reg-
ulations.
Change the wheel only on a level, firm
surface which is not slippery. Avoid
jacking the vehicle on a soft or slippery
support surface – snow, ice, loose
gravel, etc. – as either the vehicle or the
jack could slip sideways.
Position the jack on a firm support sur-
face.
Do not place wooden blocks or similar
objects under the jack. They could pre-
vent the jack from extending to its full
