iDrive, for principle details, refer to page 16 .
1. Open the start menu.
2. Press the controller to open the menu.
3. Select "Vehicle settings" and press the
controller.
4. Select "PDC" and press the controller.
5. Select "PDC display on" and press the con-
troller.
The PDC screen is activated.
The display appears on the Control Display as
soon as PDC is activated.
The setting is stored for the remote control cur-
rently in use.
System limits
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstacles always remains with
the driver. Even when sensors are involved,
there is a blind spot in which objects cannot be
detected. This applies especially in those cases
where the system approaches the physical con-
straints of ultrasonic measurement, as occurs
with tow bars and trailer couplings, and in the
vicinity of thin or wedge-shaped objects. Low
objects already displayed, e.g. a curb, can dis-
appear from the detection area of the sensors
again before a continuous tone sounds. Higher,
protruding objects, e.g. ledges, cannot be
detected. Loud noises from outside and inside
the vehicle may prevent you from hearing 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 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
page
115 .
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
This system controls the brake system's appli-
cation pressure at the rear wheels to ensure
stable deceleration.
DBC Dynamic Brake Control
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 pressure on the brake pedal for
the duration of the braking maneuver. DBC is
switched off when the brake pedal is released.
DSC Dynamic Stability Control
DSC prevents traction loss in the driving wheels
when starting off and accelerating. DSC also
detects unstable driving conditions such 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 differently in the individual wheels.
