Tire Pressure Control (RDC)
*
Flat tireIf there is a tire failure with loss of pres-
sure, the indicator lamp comes on with
a red lamp. In addition, an acoustic sig-
nal is sounded.
If this occurs, reduce vehicle speed im-
mediately and stop the vehicle in a safe
location. Avoid hard brake applications.
Do not oversteer. Replace the wheel
and flat tire.
The space-saver spare tire
* is
provided for temporary use only in
the event of a tire failure. It does not
have RDC electronics and is not moni-
tored. A full-size spare tire
* that has the
same dimensions as the tires already
mounted on the vehicle is equipped
with the necessary RDC electronics,
and will be also be monitored once the
tires have been mounted and the sys-
tem activated.<
RDC cannot alert you to severe
and sudden tire damage caused
by external factors.<
Have the tires changed by your
BMW center.
Your BMW center has been trained to
work with the RDC system and is
equipped with the necessary special
tools.<
System interferenceThe RDC system may be interrupted
temporarily by other systems or devices
that use the same radio frequency.
The yellow indicator lamp will come on
during the malfunction.
The indicator lamp also comes on
>in the event of a system fault
>if a wheel is mounted without the
appropriate electronics
>if, in addition to the spare tire
*, addi-
tional wheels with RDC electronics
are on board.
Please contact your BMW center for
additional information.

Parking lamps
With the switch in this position,
the front, rear and side vehicle
lighting is switched on. For light-
ing on one side for parking, refer to
page 83.
Low beam headlamps
When you switch the ignition off
with the low beam headlamps
on, only the parking lamps will
remain on.
"Follow-me-home lighting:"
If you actuate the headlamp
flasher after you have parked the vehi-
cle and shut off the engine, the low
beams will remain on for a brief period.
You can also have this function deacti-
vated.<

Automatic climate control 1 Air on the windshield and on the
side windows
2 Air flow toward the upper body
The side rotary dials allow you to
open and close the air supply
through an infinitely-variable range,
while the levers change the airflow
direction. The center rotary dial
controls the temperature of the air
as it flows out. Refer to page 90

There are corresponding air vents in
the rear footwell as well.

Automatic climate controlTips for pleasant drivingUse the automatic system (switch on
AUTO Ð button 7). Select an interior
temperature that is comfortable for you
Ð we recommend 70 7 (22 6). When
the outside temperature is above 42 7
(5 6), you can also use the air condi-
tioner (12). This will dry the air as well
as preventing condensation on the win-
dow surfaces Ð if there are passengers
with damp clothing, for example. Set
the air outlets (2) so that the air flows
past you and is not directed straight at
you. Set the rotary dial between the air
outlets (2) for the upper body to a me-
dium position, since air that is some-
what cooler promotes driving without
fatigue.
Detailed setting options are described
for you in the following section.
Your vehicle is set in such a man-
ner that, when you unlock the car
with your personalized remote control,
your own personalized setting of the
automatic climate control is initiated.<
Automatic air distribution
The AUTO program assumes
the adjustment of the air distri-
bution and the air supply for you and in
addition adapts the temperature to ex-
ternal influences (summer, winter) to
meet preferences you can specify. This
program maintains a comfortable in-car
climate regardless of the season. Select
an interior temperature that is comfort-
able for you Ð we recommend 70 7
(22 6). The temperature selected and
AUTO for the air supply appear in
display (10), refer to the overview on
page 86. Open the air outlets for the
upper body area. Switch on the air con-
ditioner in warm weather. The maxi-
mum cooling capacity is achieved when
you set rotary dial (3) to cold. Refer to
page 90.
Individual air distribution
You can cancel the AUTO pro-
gram by selecting specific dis-
tribution patterns to suit your
own individual requirements.
You can direct air to flow onto the win-
dows , toward the upper body ,
and into the footwell .
Temperature
The figures in the display pro-
vide a general indication of inte-
rior temperature. We recommend 70 7
(22 6) as a comfortable setting,
whether the air conditioner is operating
or not. When you start the vehicle, the
system ensures that the selected tem-
perature is reached as quickly as possi-
ble. It then maintains this temperature,
regardless of the season.
Set rotary dial (3; refer to "Draft-free
ventilation" on page 90) to a medium
setting, since air that is somewhat
cooler promotes driving without fatigue.
You can use this setting for mixing air to
make minor comfort modifications.
The full, uncontrolled heater out-
put is available starting at an inte-
rior temperature setting of 90 7
(32 6). At a setting of 60 7 (16 6),
the full cooling output is available when
the air conditioner is activated.<

Automatic climate control Air supply

By pressing the left or right half
of the button, you can vary the
air supply. By doing this, you switch off
the automatic control of the air supply.
Nevertheless, the automatic air distri-
bution remains unchanged.
When you set the lowest blower speed
by pressing the left half of the button,
all of the displays are canceled: The
blower, heating and air conditioner are
switched off, and the air supply is
stopped. You can reactivate the system
by pressing any button of the automatic
climate control.
To defrost the windshield and
side windows
This program quickly removes
ice and condensation from the
windshield and side windows.
Air conditioner
The air is cooled and dehumidi-
fied and Ð depending on the
temperature setting Ð rewarmed when
the air conditioner system is switched
on.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started.
Switch off the air conditioner at outside
temperatures below approx. 42 7
(5 6). This will help to prevent the win-
dows from fogging up.
If the windows fog over after switching
the air conditioner off, switch it back
on.
Condensation forms in the air
conditioner system during opera-
tion, which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<
Automatic recirculated air control
(AUC)
You can respond to unpleasant
external odors by temporarily
blocking the outside air. The system
then recirculates the air already within
the vehicle. By repeated actuation of
the button, you can select one of three
different operation modes.
>Indicator lamps off: Fresh air flows
into the vehicle
>Left-hand indicator lamp on Ð AUC
mode: The system detects pollutants
in the outside air and responds by
deactivating the outside air flow as
required. The system then recircu-
lates the air already within the
vehicle.
Depending on air quality require-
ments, the system automatically
switches between outside air supply
and recirculation of the air already
within the vehicle.
>Right-hand indicator lamp on: The
flow of outside air is permanently
blocked. The system recirculates the
air already within the vehicle.
If the windows fog over in the
recirculated air mode, switch this
mode off and increase the air supply as
required.<

Automatic climate controlRear window defroster
When the rear window defroster
is activated, the indicator lamp
comes on. The rear window defroster
switches off automatically. Refer to
page 70.
Draft-free ventilation Set the ventilation outlets for your upper
body area so that it is comfortable for
you:
Use rotary dials (1) to open and close
the air outlets through an infinitely-vari-
able range. You can adjust the direction
of the airflow with the levers (2).
Set the outlets so that the air flows past
you and is not directed straight at you.
The rotary dial (3) allows you to mix the
air from the outlets for your upper body
by warming or cooling the air as de-
sired.460de040
Microfilter, activated-charcoal
filterA microfilter removes dust and pollen
from the incoming outside air. The acti-
vated-charcoal filter provides additional
protection by filtering gaseous pollut-
ants from the outside air. Your BMW
center replaces the combined filter as a
standard part of your scheduled main-
tenance. A substantial reduction in air
supply indicates that the filter must be
replaced before normal maintenance.
For additional details on the filter
change, refer to page 155.
