a signal tone sounds. The setting is stored for
the remote control currently in use.
iDrive, for explanation of principle, refer to
page

Open the start menu.

Press the controller to open the menu.

Select "Vehicle settings" and press the
controller.

Change to upper field if necessary. Turn the
controller until "PDC" is selected and press
the controller.

Select "PDC display on" and press the con-
troller.

The PDC screen is activated.

The display appears on the Control Display as
soon as PDC is activated.

System limits

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. This applies especially
in those cases where the system approaches
the physical constraints of ultrasonic measure-
ment, as occurs with tow bars and trailer cou-
plings, and in the vicinity of thin or wedge-
shaped objects. Low objects already displayed,
e.g. a curb, can disappear from the detection
area of the sensors again before a continuous
tone sounds. Higher, protruding objects, e.g.
ledges, cannot be detected. Loud sources of
sound, inside and outside the vehicle, could
drown out the PDC signal tone.

Driving stability control

systems

Your BMW is equipped with an extended array
of systems designed to enhance and maintain
vehicle stability under extreme 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 page

106

CBC Cornering Brake Control

When braking during curves or when braking
during a lane change, driving stability and steer-
ing response are improved further.

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 pedal
for the duration of the full braking.

DSC Dynamic Stability Control

DSC optimizes the vehicle stability and traction.
It also detects unstable driving states such as
understeering and oversteering, and helps
keep the vehicle on course within the physical
limits by reducing the engine output and by
braking at the wheels.
The DSC is operational every time you start the
engine.

The laws of physics cannot be repealed,
even with DSC. An appropriate driving

style always remains the responsibility of the
