until "PDC" is selected and press the con-
troller.
6.Select "PDC display on" and press the con-
troller.
The PDC screen is activated.
The display is shown on the Control Display as
soon as PDC is activated.
System limitations
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstructions always remains
with the driver. Even when sensors are pro-
vided, there is a blind spot in which objects can
no longer be detected. The system is also sub-
ject to the physical limits that apply to all forms
of ultrasonic measurement, such as those
encountered with trailer towbars and hitches,
thin or wedge-shaped objects, etc. Low objects
that have already been displayed, e. g. curbs,
can disappear again from the detection area of
the sensors before or after a continuous tone
sounds. Higher, protruding objects, e.g. ledges,
cannot be detected. Therefore, always drive
cautiously, otherwise there is a risk of personal
injury or property damage.
Loud sound sources outside or inside the car
can drown out the PDC signal.<
Driving stability control
systems
Your BMW has a number of systems that help
to maintain the vehicle's stability even in
adverse driving conditions.
ABS Antilock Brake System
ABS prevents locking of the wheels during
braking. Safe steering response is maintained
even during full braking. Active safety is thus
increased.
The ABS is operational every time you start the
engine. Braking safely, refer to page126.
Electronic brake-force distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
DBC Dynamic Brake Control
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost and thus helps to achieve the short-
est possible braking distance during full brak-
ing. This system exploits all of the benefits pro-
vided by ABS.
Do not reduce the pressure on the brake for the
duration of the full braking application.
DSC Dynamic Stability Control
DSC prevents the driving wheels from losing
traction when you pull away from rest or accel-
erate. The system also recognizes unstable
driving conditions, for example if the rear of the
car is about to swerve or if momentum is acting
at an angle past the front wheels. In these
cases, DSC helps the vehicle maintain a safe
course within physical limits by reducing engine
output and through braking actions at the indi-
vidual wheels.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains the responsibility of the
driver. Therefore, do not reduce the additional
safety margin again by taking risks, as this could
result in an accident.<

The protection bars behind the rear head
restraints deploy within fractions of a second.
As a supplementary system to the reinforced
windshield frame, the rollover protection sys-
tem ensures that the necessary headroom is
maintained for all vehicle occupants.
Always keep the area of movement of the
rollover protection system clear.
In minor accidents, you are protected by the
fastened safety belt and, depending on acci-
dent severity, by the safety belt tensioner and
multi-phase airbag retention system.<
Resetting
If the rollover protection system was not
impacted after being automatically activated, it
can be reset by lowering the protection bars to
their original positions. This does not require
tools.
1.Push the locking lever to one side and hold
it there.
2.Push the protection bar halfway down from
above.
3.Release the locking lever.
4.Push the protection bar down until it snaps
into place.5.Repeat the procedure for the other protec-
tion bar.
Have the rollover protection system checked
after an unexpected activation.
Never move the retractable hardtop when
the rollover protection system is in the
activated position.
Do not make any modifications to the individual
components of the rollover protection system
or its cabling.
Work on the rollover protection system should
only be performed by a BMW center.
Incorrectly performed work on the system may
lead to system failure or incorrect operation.
To check the system and ensure flawless long-
term operation, always observe the service
intervals, refer to page79.<

>Left-hand LED on, AUC mode: a sensor
detects pollutants in the outside air. If nec-
essary, the system blocks the supply of out-
side air and recirculates the inside air. As
soon as the concentration of pollutants in
the outside air has decreased sufficiently,
the system automatically switches back to
outside air supply.
>Right-hand LED on, recirculated-air mode:
the supply of outside air is permanently
shut off. The system then recirculates the
air currently within the vehicle.
If condensation starts to form on the
inside window surfaces during operation
in the recirculated-air mode, you should switch
it off while also increasing the air flow rate as
required.
The recirculated-air mode should not be used
over an extended period of time, otherwise the
air quality inside the car will deteriorate contin-
uously.<
Via the button* on the steering wheel
You can switch quickly between the recircu-
lated-air mode and the previous mode using an
individually programmable button
on the steer-
ing wheel, refer to page11.
Residual heat
The heat stored in the engine is
used to heat the passenger com-
partment, e.g. while stopped at a
school to pick up a child.
The function can be switched on when the fol-
lowing conditions are met:
>Up to 15 minutes after the engine has been
switched off
>While the engine is at operating tempera-
ture
>As long as battery voltage is sufficient
>At an outside temperature below 777/
256
The LED is lit when the function is on.
As of radio readiness, you can set the interior
temperature, the air flow rate and the air distri-
bution.
Defrosting windows and removing
condensation
Quickly removes ice and conden-
sation from the windshield and
front side windows.
Switch on the cooling function as well.
Switching cooling function on/off
The cooling function cools and
dehumidifies the incoming air
before reheating it as required,
according to the temperature setting. This
function is only available while the engine is
running.
The cooling function helps prevent condensa-
tion on the windows or removes it quickly.
Depending on the weather, the windshield may
fog over briefly when the engine is started.
The cooling function is automatically switched
on along with the AUTO program.
Rear window defroster
The defroster is switched off auto-
matically after a certain time.
Depending on your vehicle's
equipment, the upper wires serve as an antenna
and are not part of the rear window defroster.

>a navigation DVD is inserted, but an instruc-
tion to insert the DVD appears on the Con-
trol Display?
The navigation DVD may not be the correct
DVD for the navigation system. This infor-
mation is indicated on the DVD label.
>you request the current position of your
vehicle, but do not receive a precise dis-
play?
The system is unable to receive enough
GPS signals at your current position due to
obstructions, your current position is not
yet available on your navigation DVD, or the
system is in the process of calculating your
current position. As a rule, reception is
guaranteed when you are in the open.
>the destination guidance does not accept a
destination?
The data of the destination is not stored on
the navigation DVD that is loaded. Choose a
destination as close as possible to the orig-
inal one.
>the destination guidance does not accept
an address without the street name?
On the navigation DVD, no downtown area
can be determined for the city or town
entered. Enter any street, or a destination
such as the railway station in the selected
town, and then start the destination guid-
ance.
>you want to enter a destination for the des-
tination guidance, but it is not possible to
select the letters for your desired entry?
The data of the destination is not stored on
the navigation DVD that is loaded. In this
case, the system will not offer you any let-
ters to choose from. Choose a destination
as close as possible to the original one.
>the system stops furnishing directions on
which way to turn as you approach intersec-
tions?
You are driving in an area that has not yet
been completely recorded on the naviga-tion DVD. Instead of an arrow indicating a
turn, you will see an arrow which indicates
the general direction of your planned route.
Or you have left the recommended route
and the system requires a few seconds to
calculate a new recommended route.
>the navigation system does not react to
entries?
If the battery was disconnected, it takes
about 10 minutes before the system is once
again operational.
