Automatic climate control Air conditioning
The air is cooled and
dehumidified and Ð
depending on the temperature setting Ð
warmed again when the air conditioning
is switched on.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started. You can reduce con-
densation forming on the windows by
switching on the air conditioning.
Condensation forms in the air
condition system during opera-
tion, which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<
Maximum cooling
At outside temperatures
above roughly 41 7 (5 6)
this program furnishes maximum
cooling whenever the engine is running.
The temperature displays 9 jump to
60 7 (16 6), the system reverts to
operating in the recirculated-air mode
and maximum airflow emerges from the
vent outlets only. That is why you need
to keep these open if you select this
program.
Automatic recirculated-air control
You can respond to
unpleasant external odors
by temporarily excluding the flow of
outside air. The system then recircu-
lates the air currently within the vehicle.
By repeated actuations of the button,
you can select one of three different
operation modes.
>Indicator lamps off: outside airflow
operational
>Left-hand indicator lamp on Ð AUC
mode: the system recognizes pollut-
ants in the outside air and blocks the
flow of air when necessary. The
system then recirculates the air cur-
rently within the vehicle.
Depending on the air quality, the
automatic system then switches back
and forth between outside air supply
and recirculation of the air within the
vehicle
>Right indicator lamp on Ð recircu-
lated-air mode: the flow of external
air into the vehicle is permanently
blocked. The system then recirculates
the air currently within the vehicle.
If the windows should fog over in
the recirculated-air mode, switch
it off and increase the air supply as
required.<
Rear window defroster
When the rear window
defroster is activated, the
indicator lamp comes on. The rear
window defroster switches off automat-
ically.
Residual heating mode
The heat which is stored in
the engine is utilized for
heating the interior when the engine
has been switched off (while waiting at
a railroad crossing, for instance). In
ignition key position 1, you can alter the
settings of the automatic climate con-
trol. With the ignition key in posi-tion 0,
the system automatically directs heated
air to the windshield, side windows and
footwells.
This function is available for oper-
ation when the outside tempera-
ture is below approx. 59 7 (15 6),
with the engine warm from recent oper-
ation and an adequate charge in the
battery. The LED on the button will light
up when all conditions have been
met.<

It will ventilate the interior, reducing the
temperature through the use of the
automatic climate control blowers,
whenever the vehicle is not in opera-
tion.
The parked-car ventilation system is
operated via the Multi-Information Dis-
play (MID) Ð refer to page 72 Ð or
the onboard computer. Refer to the
"Owner's Manual for Onboard Com-
puter."
You may preselect two different activa-
tion times. The ventilation will remain
activated for 30 minutes. You can also
turn it on and off directly. Since the
system uses a substantial 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 parked-car ventilation is available
for timer-controlled operation whenever
outside temperatures exceed 60 7
(16 6), and can also be activated man-
ually at any temperature. It operates
only when the vehicle is stationary.The air emerges via the vent outlets
for the upper body. Therefore, the vent
outlets must be open for the system to
operate.
You can adjust the airflow volume and
the air distribution when the ignition key
is in position 1.

Technical modifications California Proposition 65 WarningLight-emitting diodes (LEDs)Light-emitting diodes installed behind
translucent lenses serve as the light
source for many of the controls and dis-
plays 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 con-
stituents, and certain vehicle com-
ponents contain or emit chemicals
known to the State of California to
cause cancer and birth defects and
reproductive harm. In addition, certain
fluids contained in vehicles and certain
products of component wear contain or
emit chemicals known to the State of
California to cause cancer and birth
defects or other reproductive harm.
Battery posts, terminals and related
accessories contain lead and lead
compounds. Wash your hands after
handling.
Used engine oil contains chemicals that
have caused cancer in laboratory ani-
mals. Always protect your skin by
washing thoroughly with soap and
water.<

The lamps and bulbs are essential fac-
tors contributing to the safety of your
vehicle. Therefore, comply fully with the
following instructions during bulb
replacement. If you are not familiar with
any of the procedures, consult your
BMW center.
Do not touch the glass portion of
a new bulb with your bare hands
since even small amounts of impurities
burn in to the surface and reduce the
service life of the bulb. Use a clean
cloth, paper napkin, or a similar mate-
rial, or hold the bulb by its metallic
base.<
A replacement bulb set is available from
your BMW center.
Always switch off all electrical
accessories and systems before
working on them. As an alternative, you
can also disconnect the cable from the
battery's negative terminal. Failure to
observe this precaution can lead to
short circuits.
