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
condensation forming on the windows
by switching on the air conditioning.
Condensation forms in the air
conditioning during operation,
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
ventilation 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
currently 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 heat 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
control. 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 approximately 59 7
(15 6), with the engine warm from
recent operation 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 fans, when-
ever the vehicle is not in operation.
The parked-car ventilation system is
operated via the Multi-Information
Display (MID) Ð refer to page 72 Ð or the
onboard computer. Refer to the
"Onboard Computer Owner's Manual."
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
manually at any temperature. It oper-
ates only when the vehicle is stationary.The air emerges via the air outlets for
the upper body. Therefore, the air
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.

The lamps and bulbs are essential
factors 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.
To prevent injuries and damage,
comply with any instructions provided
by the bulb manufacturer.<

Repairing a flat tire Battery
If the inflation pressure does not
hold, complete step 10 and then
repeat steps 7 through 10.
The use of the M Mobility system may
be ineffective if the damaged area in
the tire is larger than approx. 0.15 in
(4 mm). If it should prove impossible to
restore the tire to operational status
using the M Mobility system, please
contact the nearest BMW center or
