Tire Pressure Control (RDC)
*
The conceptThe RDC monitors the tire pressures at
all four wheels, even when the vehicle
is moving. The system provides an alert
whenever the inflation pressure drops
significantly below the specified pres-
sure in one or more tires.
In order for the RDC system to "learn"
the correct tire inflation pressure, first
check the tire inflation pressure in all
tires. Then compare these pressures
with the tire inflation pressure chart
(page 29) and adjust if necessary. Then
activate the system.
This indicator lamp in the instru-
ment cluster informs you when-
ever the tire pressure is not
normal.
Activate the system Depending on the type of equipment,
the switch either has the letters RDC on
it or the RDC-symbol.
1 Turn the ignition key to position 2
(do not start the engine).
2 Press the switch long enough for the
indicator lamp in the instrument
cluster to light up yellow for a few
seconds.
3 After a few minutes driving time, the
RDC sets the current inflation pres-
sure in the tires as the target values
to be monitored.
You will only have to repeat this proce-
dure following a correction of the tire
inflation pressure. Otherwise, the RDC
functions automatically when the igni-
tion key is in position 2, and thus oper-
ates whenever the vehicle is driven.460us297
Loss of tire pressureIf the inflation pressure has dropped
significantly over a long period of time
(which is normal for any tire), the indi-
cator lamp will come on with a yellow
lamp.
This alerts you that you should have the
tires inflated to the specified pressures
as soon as possible.
If you are prompted to check the
tire pressure shortly after a
correction has been made, this indi-
cates that the corrected values were
not accurate. Please check the inflation
pressure again and make corrections
according to the inflation pressure
table. Then activate the system once
again.<

Side lamps
With the switch in this position,
the front, rear and side vehicle
lighting comes on. As an addi-
tional feature, you can illuminate your
vehicle on either side for parking, refer
to page 88.
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" lamps:
If you actuate the headlamp
flasher after you have turned the vehicle
off, the low beams will come on for a
brief period. You may also have this
function deactivated if you wish.<
"LAMPS ON" warningWhen you open the driver's door after
turning the ignition key to position 0, an
acoustic signal will go off for a few
seconds to remind you when the head-
lamps have not been switched off
.
Daytime running lamps
*
If you desire, the lamp switch can be
left in the second position:
When the ignition is switched off, the
external lighting is also switched off.
Turn the rotary dial to adjust the illumi-
nation intensity.460us036

Interior lampsReading lamps, frontThe reading lamps can be switched on
and off with the switch adjacent to each
lamp.Reading lamps, rearThe reading lamps can be switched on
and off with the switch adjacent ot each

In order to prevent draining the
battery, all of the lamps in the
vehicle are switched off automatically
approx. 15 minutes after the ignition
key is turned to position 0.<

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.

Air conditionerDraft-free ventilationYou can adjust the blower controls for
the upper body area to select the
optimum airflow 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 airflow with rotary dial 2.
Set the outlets so that the air flows past
you and is not directed straight at you.
Rotary dial 3 allows you to control the
temperature of the air flow from these
outlets as desired.460de040
MicrofilterAn activated-charcoal microfilter, which
traps incoming dust and pollen, has
been installed in your vehicle. Your
BMW center will replace the it during
regularly 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 165.
Rapid ventilation1 Set the fan speed control for the air
flow rate to position 4.

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 for 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 stops.
You can reactivate the system by
pressing any button of the automatic
climate control.
Defrost windows and remove
condensation
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.
Use the button to switch the air condi-
tioner off when outside air temperatures
are below approx. +41 7 (+5 6). This
will help to prevent the windows 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, that 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. When the rear window defroster
is turned on, the indicator lamp
comes on; refer to page 70.
