PDC Park Distance Control* Antilock Brake System

Signal tones

The distance from an object is indicated

in front with a higher intermittent tone,

and at the rear with a lower intermittent

tone. As the distance between vehicle

and object decreases, the intervals

between the tones become shorter.

The signal tone becomes continuous

once the distance to the nearest object

falls to below roughly 1 ft/30 cm.

The warning signal is canceled after

approx. 3 seconds if you are moving

parallel to a wall.

If there is a malfunction of the system:

The indicator lamp flashes and a short

steady signal tone is sounded

> if you activate PDC with the button

> when you select reverse for the first

time after switching on the ignition

> if a malfunction occurs while the PDC

system is active.

Switch the system off and have the

cause of the malfunction corrected by

your BMW Sports Activity Vehicle cen-

ter.

Even with PDC, final responsibility

for estimating the distance

between the vehicle and any obstruc-

tions 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 constraints 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 also disappear from the

detection area of the sensors again

before a continuous tone sounds.

Loud sources of sound, inside and out-

side the vehicle, could drown out the

PDC 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.

The concept

The ABS Antilock Brake System keeps

the wheels from locking during braking,

thereby enhancing active driving safety.

The vehicle continues to be steerable

during hard braking.

ABS also includes EBV Electronic

brake-force distribution.

Safe braking, refer to page 139.

EBV Electronic brake-force

distribution

EBV controls the brake system's appli-

cation pressure at the rear wheels to

ensure stable deceleration.

DBC Dynamic Brake Control

The Dynamic Brake Control actively

supports the driver in dangerous brak-

ing situations. When you apply the

brake pedal rapidly, the system

increases the braking effect with low

pedal pressure so that the shortest

possible braking distance is achieved.

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 application. DBC is deactivated

when you release the brake pedal.
