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.  
PDC assists you when you back into a  
parking space. Acoustic signals alert  
you to the momentary distance to an  
object behind your vehicle. To do this,  
four ultrasonic sensors in the rear  
bumper measure the distance to the  
nearest object. The range for the sen-  
sors located at both rear corners ends

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  
approx. 2 ft/60 cm behind the bumpers. between the tones become shorter. A

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.  
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.

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.<  
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 system is activated automatically  
about one second after you engage  
reverse with the ignition key in  
position 2.  
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
