Tire Pressure Monitor RDC*The conceptRDC monitors the tire pressures at all
four tires, 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 cor-
rect tire inflation pressure, check the
inflation pressures in all tires, refer to
the table on page 27 and make any
necessary corrections. Then activate
the system.
This indicator lamp in the instru-
ment cluster or the Check Con-
trol will inform you if the tire
pressure is different from the learned
values.
To switch the system on1. Turn the ignition key to position 2, do
not start the engine
2. Maintain pressure on the button until
the yellow indicator lamp in the
instrument cluster comes on for sev-
eral seconds or the message Ð TIRE
PRESSURE SET Ð appears in the
Check Control
3. After you have driven for a few min-
utes, the RDC will import the current
inflation pressure in the tires as the
reference values which the system
will monitor.
You will only have to repeat this proce-
dure if the tire inflation pressure must
be corrected. Otherwise, the RDC func-
tions automatically when the ignition
key is in position 2, and thus operates
whenever the vehicle is driven.530de232
Loss of tire pressureIf, after a certain period of time, the
inflation pressure has gone down sig-
nificantly, which is normal for any tire,
the yellow indicator lamp comes on or
the message Ð CHECK TIRE PRES-
SURE Ð appears in the Check Control.
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 cor-
rection has been made, this indicates
that the corrected values were not
accurate. Please check the inflation
pressure again and make corrections
according to the inflation pressure
table. After that reactivate the system.<

Follow me home lamps:
When you activate the headlamp
flasher after parking the vehicle and
switching off the lamps, the low beams
will come on for a brief period. You may
also have this function deactivated if
you wish.<
LIGHTS ON warningWhenever you open the driver's door,
after having turned the ignition key to
position 0, you will hear an acoustic
signal for a few seconds to remind you
that the lamps have not been switched
off.
On vehicles with alphanumeric Check
Control
*:
The reminder is given through the
Check Control.
Daytime driving lamps
*
The headlamps are automatically
switched on for daylight driving at
ignition key position 2.
Automatic headlamp control
*
When the switch is set to this
position the system automati-
cally activates or deactivates the
low beams in response to changes in
ambient light, e. g. in tunnels, at dusk,
as well as rain and snow.
The vehicle's external lamps
remain on constantly when you
switch on the fog lamps after the head-
lamps have come on automatically.<
Automatic headlamp control
cannot serve as a substitute for
the driver's judgement in determining
when the vehicle lamps should be
switched on. For example, the sensors
are not able to detect fog. To avoid
safety risks, you should respond to
these kinds of low-visibility situations
by switching the headlamps on manu-
ally.<
You can have the sensitivity of
your vehicle's automatic head-
lamp control adjusted.<

Air conditioner Temperature
The graduations on the dial
provide general reference
values for the interior temper-
ature. We recommend
+70 7/+22 6 as a comfortable
setting. When you start the vehicle, the
system adjusts the air to the selected
temperature as quickly as possible, and
then maintains that temperature
constantly.
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.
Air supply
You can adjust the air supply
through an infinitely-variable
range. The heating and venti-
lation become more and more
effective as the air supply settings are
increased. In the 0 setting, the blower
and climate control are switched off
and the outside air supply is blocked.
Rear window defroster
When the rear window
defroster is activated, the
indicator lamp comes on. The rear
window defroster switches off automat-
ically.
Air conditioning
The air is cooled and dehu-
midified and Ñ depending on
the temperature setting Ñ warmed
again. Depending on the weather, the
windshield may fog over briefly when
the engine is started. You can reduce
condensation forming on the windows
by switching on the air conditioning.
During air conditioning condensa-
tion forms, which then exits under
the vehicle. Traces of condensed water
of this kind are thus normal.<
Recirculated-air mode
You can respond to unpleas-
ant odors outside the vehicle
by temporarily switching off the outside
air supply. The system then recirculates
the air currently within the vehicle.
If you have a steering wheel with multi-
function buttons with the button for the
recirculated-air mode, you can also use
this button to switch to the recirculated-
air mode, refer to page 23.
If the windows fog over in the
recirculated-air mode, switch the
recirculated-air mode off and increase
the air supply as required.<

pollen from the incoming air. It is
replaced by your BMW Sports Activity
Vehicle center during regular mainte-
nance. A substantial reduction in air
supply indicates that the filter must be
replaced before normal maintenance.530de271

Tips for pleasant drivingUse the automatic system; that is press
AUTO button 6. Select an interior
temperature that is comfortable for you.
Detailed setting options are described
for you in the following section.
Your BMW center can program
the settings of your vehicle in such
a manner that, when you unlock the
vehicle with your individualized key,
your own personalized setting for the
automatic climate control is initiated.< Automatic air distribution
The AUTO program
assumes the adjustment of
the air distribution and the air supply for
you and also adapts the temperature to
external influences Ð summer, winter Ð
to meet preferences you can specify.
Individual air distribution
You can cancel the AUTO
program by selecting
specific air distribution
patterns for your personal
comfort, the automatic air
supply remains in operation. You can
direct air to flow onto the windows ,
toward the upper body , and into the
footwell . You can reactivate the
automatic air distribution mode by
selecting the AUTO button.
Temperature
You can make individual
temperature settings on the
driver's side or the front
passenger side. Your settings will be
shown in the display 9. The displayed
temperatures are reference values for
the interior temperature. We recom-
mend +70 7/+22 6 as a comfortable
setting, whether the air conditioner is
operating or not. When you start the
vehicle, this system ensures that the
selected temperature is achieved as
quickly as possible. It then maintains this
temperature, regardless of the season.
To change the units of measurement Ð
6/7 Ð of the display, refer to page 73
or 80.
Air supply
In the AUTO program, the
air supply is controlled
automatically. AUTO will appear in the
display 9, refer to the overview on
page 105. Press the left or right side of
the button to vary the air supply. When
your setting is displayed by bars, the
automatic air supply is switched off.
Automatic air distribution maintains its
setting. You can reactivate the auto-
matic air supply by pressing the AUTO
button.
When you press the left side of the but-
ton during operation at minimum blower
speed all displays are canceled: the
blower, heating and air conditioner are
switched off. The outside air supply is
closed. You can switch the system
back on by pressing any button of the
automatic climate control, except the
MAX button 16.
To defrost windows and remove
condensation
This program quickly
removes ice and conden-
sation from the windshield and the side
windows.

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 may be activated
when the outside temperature is
below approx. 59 7/15 6, the engine
is at operating temperature, and the
battery is adequately charged. The LED
on the button will light up when all
conditions have been met.<
Draft-free ventilation You can adjust the vent outlets for the
upper body area to select the optimum
airflow rates and directions for your
personal comfort:
1 Rotary dials for opening and closing
the vent outlets through an infinitely-
variable range
2 Selector levers for airflow direction
3 With the rotary dial you can adjust the
temperature of the incoming air.

able range between the 0 and I
settings.
In the 0 setting, the blower is switched
off and the supply of air through the
vent outlets is blocked.
Individual adjustments on the front-seat
control elements influence the air
supply for rear passenger area climate
control. 530de273
Temperature Passengers in the rear seating area can
adjust their own temperature for the
vent outlets:
>Turn toward blue Ð colder
>Turn toward red Ð warmer
When you start the vehicle, this system
ensures that the selected temperature
is achieved as quickly as possible. It
then maintains this temperature,
regardless of the season.
A temperature setting is only
possible when the blower is
switched on, not in the 0 setting.< 530de274
Particle filter,
activated-charcoal filter The particle filter removes dust and
pollen from the incoming air. The acti-
vated-charcoal filter provides additional
protection by filtering gaseous pollut-
ants from the outside air. Your
BMW Sports Activity Vehicle center
replaces this combined filter as a stan-
dard part of your scheduled mainte-
nance. A substantial reduction in air
supply indicates that the filter must be
replaced before normal maintenance.

Roller sun blinds
* Independent ventilation system
*
Roller sun blinds for rear side
windows
*
Use the strap to pull out the blinds, then
hook them in the provided attachment.
With roller sun blinds attached, do
not open the windows during
travel. The blinds may otherwise be
damaged by the wind.<
You can use this system to ventilate the
interior and lower its temperature, using
the blower of the independent ventila-
tion or of the automatic climate control.
The independent ventilation system is
operated via the Multi-Information
display MID, refer to page 84 or via the
onboard computer, refer to the sepa-
rate Owner's Manual.
You can set two different times for the
system to start; it will remain active for
30 minutes. You can also switch it on
and off directly. Since the system uses
a substantial amount of electrical
current, you should refrain from
switching it on twice in succession
without allowing the battery to be
recharged in normal operation between
use. When a preselected activation time is
set, the independent ventilation system
is operational at outside temperatures
above +60 7/+16 6, or by direct
switch activation.
The air emerges via the vent outlets for
the upper body. Therefore, the vent
outlets must be open for the system to
operate.
