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 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 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 vehicle 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

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 Sports Activity
Vehicle center to have the system
repaired.
