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 thin and
wedge-shaped objects, etc. Low objects
already displayed, e.g. a curb, can also dis-
appear from the detection area of the sen-
sors again before a continuous tone
sounds.
Loud noises from outside and inside your
vehicle may prevent you from hearing the
PDC signal tone.

Keep the sensors clean and free of ice
or snow in order to ensure that they

will continue to operate effectively.
Do not apply high pressure spray to the
sensors for a prolonged period of time.
Keep the spray at least 4 in/10 cm away
from the sensors.

Driving stability control/
ABS Antilock Brake System

Your BMW is equipped with an extended
array of systems designed to enhance and
maintain vehicle stability under extreme
conditions. The following section describes
these functions based on ABS and DSC.

The concept

ABS enhances active safety by preventing
the wheels from locking under braking.

The ABS is operational every time you start
the engine. ABS includes the functions
CBC Cornering Brake Control and EBV
Electronic Brake Force Distribution.

In case of malfunction

If the indicator lamp lights up in yel-
low, this indicates that ABS has
been deactivated in response to a

system malfunction. Conventional braking
efficiency remains available without limita-
tions. Please have the system inspected at
your BMW center.
