signal tone sounds. The display appears on the

Control Display as soon as PDC is activated.

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 provided,

there is a blind spot in which objects can no

longer 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 cou-

plings, or thin and wedge-shaped objects etc.

Low objects already displayed, e.g. curbs, can

also disappear from the detection area of the

sensors again before or after a continuous tone

already sounds. Higher, protruding objects, e.g.

ledges, cannot be detected. For this reason,

drive with care; otherwise, there is a danger of

personal injury or property damage.

Loud sources of sound, inside and outside the

vehicle, could drown out 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.

Antilock Brake System ABS

ABS prevents locking of the wheels during

braking. Safe steering response is maintained

even during full braking. Active safety is thus

increased.

The ABS is operational every time you start the

engine. For information on safe braking, refer to

page 109.

CBC Cornering Brake Control

When braking during curves or when braking

during a lane change, driving stability and steer-

ing response are improved further.

Electronic brake-force distribution

The system controls the brake pressure in the

rear wheels to ensure stable braking behavior.

Brake assistant

When you apply the brakes rapidly, this system

produces maximum braking force boosting and

thus helps to achieve the shortest possible

braking distance during full braking maneuvers.

This system exploits all of the benefits provided

by ABS.

Do not reduce the pressure on the brake pedal

for the duration of the full braking.

DSC Dynamic Stability Control

DSC optimizes vehicle stability and traction. It

also detects unstable driving states such as

understeering and oversteering, and helps

keep the vehicle on course within the physical

limits by reducing the engine output and by

braking at the wheels.

The DSC is operational every time you start the

engine.

The laws of physics cannot be repealed,

even with DSC. An appropriate driving

style always remains the responsibility of the

driver. Therefore, do not reduce the additional

safety margin further by taking risks.<

Indicator lamp

The indicator lamp goes out shortly

after the engine is started.

The indicator lamp flashes: DSC con-

trols the drive forces and brake forces.

The indicator lamp stays lit: DSC is deactivated.

M Dynamic Mode MDM

The M Dynamic Mode is a mode of the DSC

Dynamic Stability Control. It enables driving

with greater longitudinal and lateral accelera-

tion on dry road surfaces, however with limited

vehicle stability. The system does not provide

stabilizing intervention by reducing the engine

output and braking at the wheels until the abso-

lute driving limit is reached. Steering correc-

tions by the driver may also be required in this

driving state.
