PDC with visual warning

You also enjoy the option of having the
system show distances to objects in the
Control Display. The Control Display will
also indicate the presence of objects in
green before they are close enough to gen-
erate a signal tone.

Select "PDC pic." from the "Settings" menu
and confirm your selection. This activates
the PDC display.

The display then appears in the Control
Display whenever the PDC is automatically
or manually activated.

The previous display automatically reap-
pears after the system is deactivated.

Confirm

in the menu to return to

the previous display.

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, as well as 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 the
vehicle may prevent you from hearing
PDC's 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/
DSC Dynamic Stability
Control

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 DSC and ABS.

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.
The system recognizes any tendency for
the vehicle to assume an unstable attitude
such as oversteer or understeer; it then
counteracts this tendency with a combina-
tion of graduated reductions in engine
torque and selective braking intervention at
individual wheels. DSC provides optimal
stability within the limits defined by the
laws of physics.

The DSC is operational every time you start
the engine. DSC includes the functionality
of the DTC Dynamic Traction Control and
DBC Dynamic Brake Control.

With its selective braking intervention at the
individual drive wheels, DTC fulfills the
same function as a conventional limited-
slip differential to enhance traction under
