Tire Pressure Control (RDC)
*
The conceptRDC 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 system to "learn" the
correct tire inflation pressure, check the
inflation pressure in all tires according
to the inflation pressure table (page 28)
and make corrections if necessary.
Then activate the system.
This indicator lamp in the instru-
ment cluster will inform you if
the tire pressure is not correct.
Activate the systemDepending on the type of equipment,
the switch either has the letters RDC on
it or the RDC-symbol.
1 Turn ignition key to position 2 (do not
start the engine).
2 Press the switch long enough for the
yellow indicator lamp in the instru-
ment cluster to light up for a few
seconds.
3 After a few minutes driving time, RDC
sets the current inflation pressure 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, RDC
functions automatically when the igni-
tion key is in position 2, and thus oper-
ates whenever the vehicle is driven.46cus046
In the event of loss in 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 to 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.<

Tire Pressure Control (RDC)
*
In the event of a 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
signal is sounded.
If this occurs, reduce vehicle speed
immediately to 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 flat tire. It does not have
RDC electronics and is not monitored.<
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 interferenceLocal devices using the same radio
frequency can interfere with the RDC.
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 RDC
electronics.
>if additional wheels with RDC elec-
tronics are on board.
Please contact your BMW center for
additional information.

Side lamps
With the switch in this position,
the front, rear and side vehicle
lighting is switched on.
For lighting on one side for parking as
an additional feature, see page 94.
Low beam headlamps
When you switch the ignition off
with the low beam headlamps
on, only the side lamps will
remain on.
"Follow-me-home" lamps:
If you activate the headlamp
flasher after parking the vehicle, the
low-beam headlamps will come on for a
short time. You can also have this func-
tion deactivated.<

"LIGHTS ON" warningWhen you open the driver's door after
turning the ignition key to position 0,
a buzzer sounds for a few seconds to
remind you that the headlamps have
not been switched off.Daytime running lamps

If you desire, the light 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
illumination intensity.

Air conditioner1 Air onto the windshield and onto the
side windows
2 Air for the upper body area
The side rotary dials open and close
the air supply through an infinitely-
variable range; the levers will change
the direction of the air flow. The
center rotary dial controls the
temperature of the air as it flows out.
Refer to page 98

There are also vent outlets for the
rear footwell as well

Air conditionerAir supply
You can select blower speeds
from 1 to 4. The heating and
ventilation become more and
more effective as the air
supply settings are increased. In posi-
tion 0, the blower and the heater are
switched off. By using position 0, you
can totally block the interior ventilation
outlets by pressing the button for the
recirculated-air mode.
Temperature
In order to increase the
temperature of the passenger
compartment, turn it to the
right (red). Temperature regu-
lation will keep the interior temperature
you have selected constant.
Air distribution
You can direct air to flow onto
the windows , toward the
upper body and into the
footwell . All intermediate
settings are possible. In the setting,
there is a low flow of air onto the
windows to keep them free of conden-
sation. The "6 o'clock" setting is recom-
mended as a normal setting (refer also
to the illustration and overview on
page 96).
Rear window defroster
When the rear window defroster
is activated, the indicator lamp
comes on. The rear window defroster
switches off automatically. Refer to
page 78.
Air conditioner
The air is cooled and dehumidi-
fied and Ð depending on the
temperature setting Ð rewarmed when
the air conditioner 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 at outside temperatures
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, which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.
<< < <
Recirculated-air mode
You can respond to unpleasant
external odors by temporarily
blocking the outside air. The system
then 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.<< < <

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.
