PDC
*
Dynamic Stability Control (DSC)
The PDC system does not remove
the driver's personal responsibility
for evaluating the distance between the
vehicle and any obstacles. Even when
sensors are involved, there is a blind
spot in which objects cannot be
detected. This applies especially in
those cases where the system
approaches the physical constraints of
ultrasonic measurement, as occurs with
tow bars and trailer couplings, and in
the vicinity of thin and painted 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 effectively.
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).<
The concept DSC maintains vehicle stability, even in
critical driving situations.
The system optimizes vehicle stability
during acceleration and when starting
from a full stop, as well as optimizing
traction. In addition, it recognizes
unstable vehicle conditions, such as
understeering or oversteering, and, as
far as is possible within the laws of
physics, keeps the car on a steady
course by adapting the RPMs and
brake applications to the individual
wheels.
The system starts up automatically
each time you start the engine.
Indicator lamp
The indicator lamp in the instru-
ment cluster goes out shortly
after you switch on the ignition.
Refer to page 24.
Indicator lamp flashes:
The system is active and governs drive
and braking force.
If the indicator lamp fails to go out after
the engine is started, or comes on
during normal driving and stays on:
The system is either defective or was
switched off with the button: the stabi-
lizing applications described to the left
are no longer available. The vehicle will
remain completely operational,
however, without DSC.
Consult your BMW center to have the
system repaired.

Dynamic Stability Control (DSC)
Hill Descent Control
To deactivate the system Press the button (arrow); the indicator
lamp comes on and stays on.
Traction intervention remains active;
that is, braking intervention will
continue. Refer also to "Four-wheel
drive" on page 197.
In the following exceptional circum-
stances, it may be effective to deacti-
vate the DSC for a short period:
>When rocking the vehicle or starting
off in deep snow or on loose
surfaces.
>On sandy road surfaces.
>On poor surfaces with deep ruts.
>If the wheels "churn" on muddy
surfaces.
>When driving with snow chains. 530us048
As a result of the traction interven-
tion, the brakes may be subjected
to additional loads when the system is
deactivated. For this reason, it is
possible that the braking intervention
will be disabled automatically for a brief
period in order to limit brake tempera-
ture.
To maintain vehicle stability, always
drive with the system switched on when
possible.<
To reactivate the systemPress the button again; the indicator
lamp goes out.
The laws of physics cannot be
repealed, even with DSC. An
appropriate driving style always
remains the responsibility of the driver.
We therefore urge you to avoid using
the additional safety margin of the
system as an excuse for taking risks.
Do not make any modifications to the
DSC system. Service procedures on
the system are to be performed by
authorized technicians only.<
For additional details concerning DSC,
please refer to the chapter describing
"Advanced technology" on page 197.
The concept HDC is a system for driving downhill in
steep terrain. This system reduces
vehicle speed on steep downhill gradi-
ents, thus allowing you to maintain
control of your BMW under these
conditions.
The vehicle moves at slightly more than
walking speed without active interven-
tion from the driver.
You can activate HDC below approx.
20 mph (30 km/h). When driving down
steep hills, the vehicle reduces speed
automatically down to slightly more
than walking speed (approx. 5 mph/
8 km/h) and then maintains this speed
at a constant.
By applications of the brakes or accel-
erator, you can alter this speed in the
range of approx. 3 mph (5 km/h) to
approx. 20 mph (30 km/h).
HDC is deactivated automatically if you
exceed approx. 35 mph (60 km/h).

Air conditionerRecirculated air mode
You can respond to
unpleasant odors outside the
vehicle by temporarily switching off the
outside air. The system then recircu-
lates the air currently within the vehicle.
If you have a multifunction steering
wheel with the button for recirculated
air, you can also use this button to
switch to the recirculated air mode
(refer to page 26).
If the windows fog over in the
recirculated air mode, switch the
recirculated air off and increase the air
supply as required.<
Draft-free ventilation You can adjust the air outlets for the
upper body area completely for your
personal comfort:
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 levers 2.
Set the air 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:
>Turn toward blue – colder.
>Turn toward red – warmer.530us059
Rear passenger area ventilationRotary dial 1 opens the outlets in an
infinitely-variable range. You can
change the direction of the airflow with
levers 2.
The air that flows out here is somewhat
cooler than the air delivered to the foot-
well.530us140

Automatic climate control
*
Automatic recirculated air
control (AUC)
If there are unpleasant
odors or pollutants in the
outside air, you can temporarily block
the airflow from the outside. The
system then recirculates the air
currently within the vehicle.
Press the button repeatedly to run
through the following control sequence:
>Indicator lamps off: outside airflow
operational.
>Left-hand indicator lamp on – AUC
mode: the system recognizes pollut-
ants in the outside air and blocks the
flow of air when necessary. The
system then recirculates the air
currently within the vehicle.
Depending on the air quality, the
automatic system then switches back
and forth between outside air supply
and recirculation of the air within the
vehicle.
>Right-hand indicator lamp on: the
flow of external air into the vehicle is
completely blocked. The system then
recirculates the air currently within
the vehicle.
If you have a multifunction steering
wheel with the button for recirculated
air (refer to page 26), you can also use
this button to switch between "Off" and
the recirculated air mode or AUC and
the recirculated air mode.
If the windows fog over in the
recirculated air mode, switch the
recirculated air off and increase the air
supply as required.< Rear window defroster
When the rear window
defroster is activated,
the indicator lamp comes on. The
rear window defroster switches off
automatically.
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.<

Cargo areaPull-out cargo floor
*
To release, pull the handle recess
upward. Then pull the floor out.
Do not drive when the cargo floor
is pulled out.
Do not release the cargo floor on steep
grades. If you do, it could extend auto-
matically and cause personal injuries.
A load which is not properly secured
could begin to slide if the floor extends
automatically and then drop to the
ground as a result of the rapid braking
of the cargo floor at the limit stop.< 530us087
When it is extended, you can load the
cargo floor:
>With up to 990 Ibs (450 kg),
distributed evenly across the
entire surface.
>With up to 330 Ibs (150 kg) on the
rear edge.
Do not overload the cargo floor
when it is extended. If you do so,
it could cause damage.
When you slide the cargo floor back in,
do not grasp it on the bottom. If you do
so, there is a risk of personal injury.<
Raise the cargo floorFor access to the spare wheel or other
stored items:
Swing the cargo floor up and secure it
with the rod (see detail).
If your vehicle has a partition net
*:
Take the bag with the partition net
out of the bracket (refer to page 125),
before you raise the cargo floor panel.
Otherwise, the bag could slide down-
ward.<
