System limits
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any objects always remains with the
driver. Even when sensors are involved, there is
a blind spot in which objects cannot be
detected. The system's detection of objects 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 or wedge-shaped
objects. Low objects already indicated, such as
curb edges, may enter the blind spot of the sen-
sors before or after a continuous audible signal is given. Higher, protruding objects, such as
wall ledges, may not be detectable.
Loud noises from outside and inside the vehicle
may also prevent you from hearing the PDC's
signal tone.<
Driving stability control
systems
Your BMW is equipped with an extended array
of systems designed to enhance and maintain
vehicle stability under extreme conditions.
ABS Antilock Brake System
ABS prevents the wheels from locking during
braking. Safe steering response is maintained
even during hard braking. This increases active
driving safety.
ABS is operational every time you start the
engine. For information on safe braking, refer to
page123.
CBC Cornering Brake Control
This system provides further enhancements to
vehicle stability and steering response when
braking while cornering or when braking during
a lane change.
Electronic brake-force distribution
The system controls the brake pressure in the
rear wheels to ensure a stable braking behavior.
Brake assistant
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost and thus helps to achieve the short-
est possible braking distance during full brak-
ing. This system exploits all of the benefits pro-
vided by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.
DSC Dynamic Stability Control
DSC prevents traction loss in the driving wheels
when starting off and accelerating. The system
also detects unstable driving conditions such

Technology for comfort, convenience and safety
88 as fishtailing or sliding of the vehicle's front
wheels. In these cases, DSC helps the vehicle
safely stay on course within the physical limits
by reducing the engine output and by applying
the brakes in the 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The laws of physics cannot be repealed,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 your added margin of
safety by driving dangerously; otherwise you
run the risk of causing an accident.<
Deactivating DSC
1.Press the button to open the start
menu.
2.Move the controller toward "Settings".
3.Select "DTC" and press the controller for at
least 3 seconds.
The LED for "DTC" and the DSC indicator lamp
on the Info Display light up. DTC Dynamic Trac-
tion Control and DSC Dynamic Stability Control
are deactivated together. Interventions promot-
ing stability and forward momentum will no
longer be carried out.
To promote enhanced operating stability, reac-
tivate DSC again as soon as possible.
Activating DSC
Select "DTC" and press the controller.
The LED on the Control Display and the DSC
indicator lamp on the Info Display go out.
For control purposes
The indicator lamp flashes:
DSC is controlling the drive forces and
brake forces. The indicator lamp comes on:
DSC is deactivated.
DTC Dynamic Traction Control
DTC is a version of DSC that is optimized for
forward momentum in special road conditions.
The system ensures maximum forward
momentum, but with limited driving stability.
Therefore, drive with appropriate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:
>When driving on snow-covered uphill
grades, in slushy snow or on uncleared,
snow-covered roads
>When rocking a stuck vehicle free or when
starting off in deep snow or on loose ground
>When driving with snow chains
