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
generate 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 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. After initial
detection, low objects such as curbs, etc.,
may disappear again before the system
starts to generate a continuous warning
tone. 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
difficult driving conditions, such as on
snow, etc. Indicator lamps
The indicator lamp in the Info
Display goes out soon after you
start the engine.
If the indicator lamp flashes:
DSC controls the drive and braking forces.
The indicator lamp stays lit:
DSC has been switched off via the Control
Display.

limited system response up to a speed of
approx. 45 mph (70 km/h). Intervention for
stability-enhancement is reduced. Do not
make any modiÞcations to the DSC system.
Never allow anyone other than authorized
professional technicians to carry out
service or repairs on the DSC system.< Dynamic Brake Control DBC

When you apply the brakes rapidly, this
system automatically produces the
maximum braking force boost and thus
helps to achieve the shortest possible
braking distance during "panic stops." This
system exploits all of the benefits provided
by ABS.
Do not reduce the pressure on the brake
pedal for the duration of the brake applica-
tion. When the brake pedal is released, the
DBC is deactivated.
In the event of a malfunction, the
warning lamp comes on with a
yellow lamp. Have the system
checked and repaired at your BMW center
as soon as possible.
Check Control messages, refer to page 80.
Please note the supplementary information
provided in the Control Display.
Warning lamp on Canadian models.Driving stability control/
ABS Antilock Brake System The concept ABS enhances active safety by preventing
the wheels from locking under braking.
ABS incorporates CBC and EBV. In case of malfunction
If the indicator lamp lights up in
yellow, 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.
Cornering Brake Control CBC CBC is a technical advance based on ABS.
It provides further enhancements in vehicle
stability and steering response during lane
changes and cornering at high rates of
lateral acceleration. EBV Electronic brake-force
distribution EBV controls the brake system's applica-
tion pressure at the rear wheels to ensure
stable deceleration. In case of malfunction
If the brake system warning lamp
lights up in red, appearing together
with the yellow lamps for ABS and
DSC: the stability control is no
longer operational.
If all three lamps light up in yellow:
malfunction in the stability control
systems.
While you may continue, you should
remember to proceed cautiously and drive
defensively while avoiding full brake appli-
cations.
Please have the system checked at the
nearest BMW center.
Check Control status messages, refer to
page 80. Please note the supplementary
information provided in the Control Display.

This symbol will appear in the
Check Control panel to inform you
when the inflation pressure varies
from that stored in the system. A text
message appears at the same time. Please
take note of the additional information in
the Control Display panel.
You can find more information on the
Check Control starting on page 80.
The RDC cannot alert you to severe
and sudden tire damage caused by
external factors.<
To initialize the system 1.With the vehicle parked, switch on the
ignition
2.Select "RDC" from the "Settings" menu
and confirm your selection. The initializa-
tion menu appears. "INITIALIZE" 1.Select and confirm
2.RDC is initialized. A message appears in
the Check Control panel
3.After several minutes of driving RDC will
adopt the tires' current inflation pressures
as its references.
The current data appear in the Control
Display. These figures are more accurate than those that appear on the inflation
gauges at filling stations, etc.
The only time you will need to repeat this
procedure is after correcting your tire pres-
sures. Because RDC automatically
assumes operation each time you switch
on the ignition, it is on duty whenever you
drive.
If the system detects a flat tire during
the initialization process, the tires in
the Control Display will appear in red.<
Do not start initialization
Select and confirm to return to the
"Settings" menu.
Status indicators in the Control
Display The status of the system is indicated by the
color of the tires. GreenTire inflation pressures correspond to the
initialized level.YellowThe inflation pressures in the tires have
fallen to below the specified level, which is
normal in every tire after a certain amount
of time.
This alerts you to have the tires inflated to
the specified pressures as soon as
possible. RedPressure loss in indicated tire.
If this occurs, reduce vehicle speed imme-
diately and stop the vehicle. Avoid hard
and sudden steering and braking maneu-
vers. BlackThe system is being initialized.
The system needs several minutes to
complete the initialization process, after
which it is ready to detect and report tire
problems.
