Air conditioningDraft-free ventilation You can adjust the air outlets for the
upper body area for optimal personal
comfort:
1 Rotary dials for opening and closing
the vent outlets through an infinitely-
variable range
2 Levers for adjusting airflow direction
3 Rotary dial allows you to control the
temperature of the airflow as desired:
>Turn toward blue Ð colder
>Turn toward red Ð warmer.390de685
Rear passenger area ventilation1 Rotary dial for opening and closing
the vent outlets through an infinitely
variable range
2 Levers for selecting airflow direction.
The air that flows out here is somewhat
cooler than the air delivered to the foot-
well.Microfilter The microfilter removes dust and pollen
from the incoming air. Your BMW
center will replace it during routine
maintenance. A substantial reduction in
airflow indicates that the filter needs to
be replaced early.390de687
To defrost windows and remove
condensation 1. Use the rotary temperature selector
to set the system for an interior
temperature that you find comfort-
able, such as 70 7 (22 6)
2. Set the air distribution rotary dial
to
3. Set the blower/air supply rotary dial
completely to the right
4. Close the air outlets in the rear

Microfilter, activated-charcoal
filterThe microfilter removes dust and pollen
from the incoming air. The activated-
charcoal filter provides additional
protection by filtering gaseous pollut-
ants from the outside air. Your BMW
center replaces this combined filter as a
standard part of your scheduled main-
tenance. A substantial reduction in
airflow indicates that the filter must be
replaced before scheduled mainte-
nance.
To operate, press the button briefly with
the ignition key in position 1 or 2.

Use the strap to extract the blinds, then
hook them in the attachment provided.390us730
This system allows you to ventilate the
interior and lower its temperature using
the blower of the automatic climate
control.
The parked-car ventilation system is
operated via the Multi-Information
Display (MID) Ð refer to page 90 Ð or
the onboard computer. Refer to the
separate Owner's Manual.
You can set two different times for the
system to start; it will remain active for
30 minutes. You can also turn it on and
off directly. Since the system uses a
substantial amount of electrical current,
you should not activate it twice in
succession without allowing the battery
to be recharged in normal operation
between use.
The parked-car ventilation system is
available for timer-controlled operation
at outside temperatures above 60 7
(16 6) as well as for manual operation
at any temperature, provided that the
vehicle is stationary.
The air emerges via the vent outlets
for the upper body. Therefore, the
vents must be open for the system to
operate.

Brake fluid
The warning lamp for the brake
system's hydraulic circuits
comes on/the message
"CHECK BRAKE FLUID"
appears in the Check Control
display panel: Brake fluid level
too low.
To add brake fluidThe brake fluid reservoir is located
under the microfilter housing on the
driver's side of the vehicle. For adding
brake fluid or for determining and
correcting the cause of brake fluid loss,
consult your BMW center. Your BMW
center is familiar with the specifications
for factory-approved brake fluids
(DOT 4).
Brake fluid loss may result in extended
brake pedal travel. Should this occur,
refer to the notes on page 132.
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the safety and reli-
ability of the brake system, have
the brake fluid changed every two years
by a BMW center. Refer also to the
Service and Warranty Information
Booklet (US models) or to the Warranty
and Service Guide Booklet (Canadian
models).
Brake fluid is toxic and damages the
vehicle's paint. You should always store
it in its original container and in a loca-
tion which is out of reach of children.
Do not spill the fluid and do not fill the
brake fluid reservoir beyond the MAX
mark. The brake fluid could ignite upon
contact with hot engine parts and
cause serious burns.<
Comply with the applicable envi-
ronmental laws regulating the
disposal of brake fluid.<

Light-emitting diodes (LEDs)Light-emitting diodes installed behind
translucent lenses serve as the light
source for many of the controls and
displays in your vehicle. The concept
behind their operation is related to that
employed for lasers, and they are offi-
cially designated as Class 1 light-emit-
ting diodes.
Do not remove the protective lens
and avoid staring directly at the
unfiltered beam for extended periods
(several hours), as inflammation of the
iris could result.<
California laws require us to state the
following warning:
Engine exhaust, some of its
constituents, and certain vehicle
components contain or emit chemicals
known to the State of California to
cause cancer and birth defects or other
reproductive harm.<
