PDC provides extra safety and conve-
nience during parking maneuvers. 
Acoustic signals alert you to the 
momentary distance to an object 
behind your vehicle. The system fea-
tures four ultrasonic sensors mounted 
in your rear bumper. The monitoring 
range for the two corner sensors 
extends outward roughly 2 ft/60 cm 
behind the bumpers, while two centrally 
located sensors detect objects at dis-
tances of up to approx. 5 ft/1.50 m.

PDC is a parking aid that can 
identify objects if they are 

approached slowly, as is generally the 
case when parking. Avoid driving 
towards objects rapidly; due to underly-
ing physical principles, the system may 
otherwise alert you too late for you to 
take evasive steps.

<

The system starts to operate automati-
cally approx. one second after you 
select reverse or move the selector 
lever into the R position with the igni-
tion key in position 2. 

Let this short period elapse before 
driving backwards.

<

PDC is deactivated when you shift back 
out of Reverse.

You can have a signal set to con-
firm that the PDC has been acti-

vated.

<

The distance to the nearest object is 
indicated by a tone sounding at various 
intervals. As the distance between vehi-
cle and object decreases, the intervals 
between the tones become shorter. A 
continuous tone indicates the pres-
ence of an object less than 1 ft/30 cm 
away.

The warning signal is canceled after 
approx. three seconds if the distance to 
the object 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 the problem fixed by 
your BMW center.

PDC does not remove the driver's 
personal responsibility for evaluat-

ing the distance between the vehicle 
and any objects. 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 ultrasonic measurement, as 
occurs with tow bars and trailer cou-
plings, and in the vicinity of thin or 
wedge-shaped objects. Moreover, low 
objects that have already been 
detected – such as a curb edge – can 
disappear out of the detection range of 
the sensors before a continuous tone 
sounds.
Loud sources of sound from outside or 
inside 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 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.
