The concept

PDC provides extra safety and conve-

nience during parking maneuvers by

providing an acoustic signal to indicate

the distance to an object. To do this,

four ultrasonic sensors in the rear

bumper measure the distance to the

nearest object.The monitoring range for

the two rear sensors extends outward

roughly 2 ft (60 cm). The range for the

two center sensors is approx. 4.9 ft

(1.50 m) wide.

The system starts to operate automati-

cally about one second after you select

reverse with the ignition key in

position 2. PDC is deactivated when

you shift back out of reverse.

Acoustic signals

The distance to the nearest object is

indicated by a tone sounding at various

intervals. As the distance between

vehicle and object decreases, the inter-

vals between the tones become

shorter. A continuous tone indicates the

presence of an object less than 1 ft

(30 cm) away.

The warning signal is canceled after

approx. three seconds if the distance to

the obstacle remains constant during

this time (if you are moving parallel to a

wall, for instance).

System malfunctions will be indicated

by a continuous high-pitched tone

when the system is activated the first

time. Please have your BMW center

resolve the problem.

The PDC does not remove the

driver's personal responsibility

for evaluating the distance between the

vehicle and any obstacles. 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 limits of ultra-

sonic measurement, as occurs with tow

bars and trailer couplings, and in the

vicinity of thin or wedge-shaped

objects.

Certain sources of sound, such as a

loud radio, could drown the PDC signal

tone.<

Keep the sensors clean and free

of ice or snow in order to ensure

that they continue to operate effec-

tively.

Do not apply high pressure spray to the

sensors for a prolonged period of time.

Always maintain a distance of more

than 4 in (10 cm).<
