Park Distance Control (PDC)
*
ASC+T/DSC
*
PDC does not remove the driver's
personal responsibility for evalu-
ating the distance between the vehicle
and any obstacles. Even with the
sensors, there is a blind spot in which
objects cannot be detected. This
applies especially in those cases where
the system approaches the physical
limits of ultrasonic measurement, as
occurs with tow bars and trailer
couplings, and in the vicinity of thin or
wedge-shaped objects.
Certain sources of sound, such as a
loud radio, could drown out the PDC
signal tone.<
Keep the sensors clean and free
of ice or snow in order to ensure
that they continue to operate effec-
tively.
Do not apply high pressure spray to the
sensors for a prolonged period of time.
Maintain an adequate distance of more
than 4 in (10 cm).<
Automatic Stability Control plus
Traction (ASC+T)/Dynamic
Stability Control (DSC)
*
These systems contribute to additional
vehicle stability, especially during
acceleration and when cornering.
The DSC system enhances the benefits
of the ASC+T. In addition to optimizing
vehicle stability and traction during
acceleration or when starting from a
standstill, a further benefit is realized in
cornering. This, of course, is true only
within physically feasible limits.
The system activates automatically
each time you start the engine.

Level control system
*
Tire Pressure Monitor (RDC)
*
The warning lamp for the level
control system comes on, or the
message "SELFLEVEL
SUSP.INACT" appears in the Check
Control: there is a malfunction in the
self-level control system.
Stop and inspect the vehicle. If it is
riding significantly lower in the rear than
in the front, or if it is sitting at an incline
(left rear compared to right rear),
consult the nearest BMW center. Drive
with appropriate caution in the mean-
time. The vehicle has reduced ground
clearance or driving comfort is notice-
ably reduced.
Even if the attitude of the vehicle is
normal, you should consult the nearest
BMW center if the warning lamp indi-
cates a system fault.
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. Refer to
the table of "Tire inflation pressures"
beginning on page 27 and make any
necessary corrections. Then activate
the system.
This indicator lamp in the instru-
ment cluster or the Check
Control will inform you if the tire
pressure is not correct.
Activate the system1. 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
several seconds or the message
"SET TIRE PRESSURE" appears in
the Check Control panel
3. After you have driven for a few
minutes, 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.390de704

Parking lamps (side marker
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, refer to page 102.
Low beams
When the ignition is switched off
while the low beams are on, the
headlamps go out and only the
parking lamps (side marker lamps)
remain on.
390de732
"Follow me home":
When you activate the headlamp
flasher after parking the vehicle and
switching off the lights, the low beams
will come on for a brief period. You may
also have this function deactivated if
you wish.<
"LIGHTS ON" warningWhen the driver's door is opened with
the ignition key at position 0 a chime
will sound for several seconds to
remind you that you have forgotten to
switch off the lights
.
Vehicles with alphanumeric Check
Control
*:
The reminder is provided by the Check
Control, refer to page 85.
Daytime driving lamps
*
The headlamps are automatically
switched on for daytime driving at
ignition key position 2.
Automatic headlamp control
*
When the switch is set to this
position the system automati-
cally activates and cancels the
low beams in response to changes in
ambient light ( in tunnels, at dusk, etc.)
as well as rain and snow.
The vehicle's external lights
remain on constantly when you
switch on the front fog lamps after the
headlamps have come on automati-
cally.<
Automatic headlamp control
cannot serve as a substitute for
the driver's judgement in determining
when the vehicle lights 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.<

area operates the same way.390de638
The reading lamps are located in the
front near the interior lamp. There are
also reading lamps in the rear. They can
be switched on and off with the switch
(arrow) adjacent to each lamp.
To avoid subjecting the battery to
excessive loads, all of the lamps
within the vehicle are automatically
switched off approximately 15 minutes
after you turn the ignition key to posi-
tion 0.< 394de301

Air conditioningTemperature
The numbers in the display
panel are reference figures for
general orientation. We
recommend a setting of 70 7
(22 6) for a congenial in-car climate.
When you start the vehicle, this system
adjusts the air to the selected tempera-
ture as quickly as possible, and then
maintains that temperature constantly.
Air distribution
You can direct the emerging
air toward the windows ,
toward your upper body or
into the footwell . All inter-
mediate settings are also available. In
the setting, there is a low flow of air
onto the windows to keep them free of
condensation.
Air supply
You can control the emerging
air's flow rate through an infi-
nitely-variable range. The
heating and ventilation
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
The indicator lamp comes
on to indicate that the rear
window defroster is in operation. The
rear window defroster switches off
automatically.
Cooling
The air conditioning cools
and dehumidifies the
incoming air before reheating it to the
selected temperature. 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.
Condensation forms in the air
conditioning 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 odors in the
surrounding environment by using this
mode to temporarily suspend the flow
of outside air into the vehicle's interior.
The system then recirculates the air
currently within the vehicle.
If your vehicle is equipped with a multi-
function steering wheel
featuring a
recirculated-air button then you can
also select the recirculated-air mode
from this location (refer to page 22).
If the windows should fog over in
the recirculated-air mode, switch
the recirculated-air mode off and
increase the air supply as required.<

Air conditioningDraft-free ventilation You can adjust the air outlets for the
upper body area for optimal personal
comfort:
1 Rotary dials for opening and closing
the vent outlets through an infinitely-
variable range
2 Levers for adjusting airflow direction
3 Rotary dial allows you to control the
temperature of the airflow as desired:
>Turn toward blue Ð colder
>Turn toward red Ð warmer.390de685
Rear passenger area ventilation1 Rotary dial for opening and closing
the vent outlets through an infinitely

2 Levers for selecting airflow direction.
The air that flows out here is somewhat
cooler than the air delivered to the foot-
well.Microfilter The microfilter removes dust and pollen
from the incoming air. Your BMW
center will replace it during routine
maintenance. A substantial reduction in
airflow indicates that the filter needs to
be replaced early.390de687
To defrost windows and remove
condensation 1. Use the rotary temperature selector
to set the system for an interior
temperature that you find comfort-
able, such as 70 7 (22 6)
2. Set the air distribution rotary dial

Tips for pleasant drivingUse the automatic system, that is,
press AUTO button 6. Select an interior
temperature that you find comfortable.
Detailed setting options are described
for you in the following section.
You can make the settings of your
vehicle in such a manner that,
when you unlock the vehicle with the
remote control of your personal 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 (summer, winter) to
meet preferences you can specify.
Individual air distribution
You can cancel the AUTO
program by selecting
specific distribution patterns
to suit your own individual
requirements. While the
AUTO program is then deactivated, the
automatic airflow control remains in
operation. The system directs air to the
windows , the upper body and
into the footwells . You can reacti-
vate 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 selection appears
in display panel 7. The numbers that
appear in the panel are reference
figures for interior temperature. We
recommend a setting of 72 7 (22 6)
for a congenial interior climate, even
when the air conditioner is in operation.
When you start the vehicle, the system
ensures that the selected temperature
is achieved as quickly as possible. It
then maintains this temperature,
regardless of the season.
Air supply
AUTO appears in display
panel 9, while the AUTO
program automatically controls the flow
of incoming air, refer to overview on
page 107. You can use "+" and "Ð" to
vary the airflow. When your setting is
displayed by bars, the automatic airflow
is switched off. Automatic air distribu-
tion maintains its setting. You can reac-
tivate the automatic airflow by pressing
the AUTO button.
When you press "Ð " during operation at
minimum blower speed all displays are
canceled: the blower, heating and air
conditioner are switched off. The
outside air supply is deactivated. By
pressing any button of the automatic
climate control (except the MAX
button 16), you can switch the system
back on.
To defrost windshield and
windows
This program quickly
removes ice and conden-
sation from the windshield and the side
windows.

Residual heating 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. In ignition key position 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.<
