Air conditionerDraft-free ventilation You can adjust the air outlets for the
upper body area to select the optimum
air flow rates and directions for your
personal requirements:
Use rotary dials 1 to open and close the
air outlets through an infinitely-variable
range. You can adjust the direction of
the air flow with levers 2.
Set the outlets so that the air flows past
you and is not directed straight at you.
Rotary dial 3 allows you to mix the air
from the outlets for your upper body
with more or less cool air..460de040
Microfilter An activated-charcoal microfilter, which
traps incoming dust and pollen, has
been installed in your vehicle. Your
BMW center will replace it during regu-
larly scheduled maintenance. A
substantial reduction in air supply indi-
cates that the filter must be replaced
before normal maintenance.
For additional details on the filter
change, refer to page 180.

Draft-free ventilation You can adjust the blower controls for
the upper body area to select the
optimum air flow rates and directions
for your personal requirements:
Use rotary dials 1 to open and close the
air outlets through an infinitely-variable
range. You can adjust the direction of
the air flow with levers 2.
Set the outlets so that the air flows past
you and is not directed straight at you.
Rotary dial 3 allows you mix the air from
the outlets for your upper body by
warming or cooling the air as desired.460de040
Microfilter/Activated-charcoal
filterThe microfilter filters out dust and
pollen from the incoming air. The acti-
vated-charcoal filter helps clean the
incoming outside air of gaseous pollut-
ants. Your BMW center will replace this
combined filter during the regularly
scheduled maintenance. A substantial
reduction in air supply indicates that the
filter must be replaced before normal
maintenance.
For further information on the filter
change, refer to page 180.

Vehicle storage
If you plan on parking the vehicle
for more than three months, have
the maintenance operations described
on this page performed.<
Preparations for storageHave your BMW center perform the
following procedures:
1 Clean and apply a rustproofing agent
or other treatment to the engine,
engine compartment, undercarriage,
axles and major components in
accordance with approved repair
procedures. First wash the vehicle
surface, then clean the interior,
following up with paint and chrome
care, after which you clean the
rubber seals for the hood and doors.
2 Change the engine oil and oil filter at
operating temperature. As an addi-
tional corrosion protection measure,
an anticorrosive agent can be added
to the engine in accordance with the
manufacturer's instructions.
3 Check the coolant level and concen-
tration and top up if necessary.
4 Check the fluid level of the wind-
shield washer fluid reservoir and top
up if necessary.
5 Fill the fuel tank completely to pre-
vent the formation of condensation.
6 Increase the tire inflation pressure to
51 psi (350 kilopascal).
Before parking the vehicle1 To prevent the brake discs and
drums from corroding, dry the park-
ing and footbrake by applying the
brakes.
2 Park the vehicle in a covered, dry and
well-ventilated space. Place the
transmission in 1st gear or set the
selector lever to the "P" position.
Chock the wheels to prevent the
vehicle from rolling if necessary. Do
not set the parking brake.
3 Remove the battery, charge it
completely and store it in a cool (but
frost-free) room.
4 Remove the hardtop and store
separately. Refer to page 130.
5 Close the convertible top.During storageRecharge the battery every six months.
If it is not recharged, it will not be
serviceable. Every time the battery is
drained, especially over extended
periods, its service life is reduced.
Removing the vehicle from
storageRecharge the battery if the "Magic
Eye"
* turns black. Refer to page 176.
Then have Inspection I performed by
your BMW center, including a brake
fluid replacement if necessary. Refer
to the Service Manual.

Any BMW center will be glad to inform
you of the advisability, legal require-
ments and factory recommendations
regarding technical modifications on
your vehicle. For this purpose, the
BMW center will require the Vehicle
Identification Number and, in some
cases, also the engine number. 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.
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.<
