Malfunction The LED in the button flashes and a short continuous tone sounds. PDC is malfunctioning. Switch off PDC. Have the system checked. To prevent this problem, keep the sensors clean and free of ice or snow in order to ensure that they will continue to operate effectively. When using high-pressure washers, do not spray sensors for long periods and keep the sprayer at least 4 in/10 cm away from the sensors. Electronic brake-force distribution The system controls the brake pressure in the rear wheels to ensure a stable braking behavior. Brake assistant When the brake pedal is depressed quickly, this system automatically generates a maximum braking force distribution and thus helps keep the braking distance to a minimum during full braking. This system exploits all of the benefits provided by ABS. As long as you want full braking to continue, do not reduce pressure on the brake. 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 involved, there is a blind spot in which objects cannot be detected. The system is also subject to the physical limits that apply to all forms of ultrasonic measurement, such as those encountered with tow bars and trailer couplings, or thin and wedge-shaped objects. Low objects already displayed, e.g. curb edges, can come into the blind spot of the sensors before or after a continuous tone sounds. The system may fail to detect higher obstacles such as projections from walls. Loud sources of sound, inside and outside the vehicle, could drown out the PDC signal tone.< DSC Dynamic Stability Control DSC prevents slip at the drive wheels when starting off and accelerating. The system also detects unstable driving conditions, such as a fishtailing of the vehicle's rear end or the sliding of the vehicle on its front wheels. In these circumstances, DSC helps keep the vehicle on a safe path, within physical limits, by reducing engine output and by applying the brakes in individual wheels. The laws of physics cannot be repealed, even with DSC. An appropriate driving style always remains the responsibility of the driver. Do not squander the additional margin of safety by driving dangerously; otherwise, you run the risk of causing an accident.< Controls Reference Mobility Maintain pressure on the button until the DSC indicator lamp lights up, but do not press for longer than approx. 10 seconds.

Malfunction
The LED in the button flashes and a short con-
tinuous tone sounds. PDC is malfunctioning.
Switch off PDC. Have the system checked.
To prevent this problem, keep the sensors
clean and free of ice or snow in order to ensure
that they will continue to operate effectively.
When using high-pressure washers, do not
spray sensors for long periods and keep the
sprayer at least 4 in/10 cm away from the sen-
sors.
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 involved,
there is a blind spot in which objects cannot be
detected. The system is also subject to the
physical limits that apply to all forms of ultra-
sonic measurement, such as those encoun-
tered with tow bars and trailer couplings, or thin
and wedge-shaped objects. Low objects
already displayed, e.g. curb edges, can come
into the blind spot of the sensors before or after
a continuous tone sounds. The system may fail
to detect higher obstacles such as projections
from walls.
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 even under unfavorable driving
conditions.
ABS Antilock Brake System
ABS prevents the wheels from locking during
braking. Safe steering response is maintained
even during full braking. This results in an
increase in the active safety.
ABS is operational every time you start the
engine. Safe braking, refer to page
84
.
Electronic brake-force distribution
The system controls the brake pressure in the
rear wheels to ensure a stable braking behavior.
Brake assistant
When the brake pedal is depressed quickly, this
system automatically generates a maximum
braking force distribution and thus helps keep
the braking distance to a minimum during full
braking. This system exploits all of the benefits
provided by ABS.
As long as you want full braking to continue, do
not reduce pressure on the brake.
DSC Dynamic Stability Control
DSC prevents slip at the drive wheels when
starting off and accelerating. The system also
detects unstable driving conditions, such as a
fishtailing of the vehicle's rear end or the sliding
of the vehicle on its front wheels. In these cir-
cumstances, DSC helps keep the vehicle on a
safe path, within physical limits, by reducing
engine output and by applying the brakes in
individual wheels.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains the responsibility of the
driver. Do not squander the additional margin of
safety by driving dangerously; otherwise, you
run the risk of causing an accident.

Deactivating DSC
Maintain pressure on the button until the DSC
indicator lamp lights up, but do not press for
longer than approx. 10 seconds. DTC Dynamic
Traction Control and DSC are deactivated
