Technology for safety and driving convenience
Park Distance Control (PDC)*
The concept
PDC assists you when you back into a 
parking space. Acoustic signals alert 
you to the momentary distance to an 
object behind your vehicle. The system 
features four ultrasonic sensors 
mounted in your rear bumper. The mon-
itoring range for the two corner sensors 
extends outward roughly 2 ft/60 cm, 
while two centrally located sensors 
detect objects at distances 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 shift 
into Reverse or move the selector lever 
into the R position with the ignition 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 signal then sounds when 
you shift into Reverse or move the 
selector lever into the R position.

Acoustic signals
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 refer the problem to 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.
