Malfunction
The LED in the button flashes and a short con-
tinuous tone sounds. PDC is malfunctioning. 
Switch off PDC. Have the system checked.
To prevent this problem, keep the sensors 
clean and free of ice or snow in order to ensure 
that they will continue to operate effectively. 
When using high-pressure washers, do not 
spray sensors for long periods and keep the 
sprayer at least 4 in/10 cm away from the sen-
sors.
System limits
Even with PDC, final responsibility for 
estimating the distance between the 
vehicle and any obstructions always remains 
with the driver. Even when sensors are involved, 
there is a blind spot in which objects cannot be 
detected. The system is also subject to the 
physical limits that apply to all forms of ultra-
sonic measurement, such as those encoun-
tered with tow bars and trailer couplings, or thin 
and wedge-shaped objects, etc. Low objects 
already displayed, e.g. a curb, can come into the 
blind spot of the sensors before a continuous 
tone sounds. The system may fail to detect 
higher obstacles such as ledges.
Loud sources of sound, inside and outside the 
vehicle, could drown out the PDC signal tone.

Driving stability control 
systems
Your BMW is equipped with an extended array 
of systems designed to enhance and maintain 
vehicle stability even under unfavorable driving 
conditions.
ABS Antilock Brake System
ABS prevents the wheels from locking during 
braking. Safe steering response is maintained 
even during full braking. This results in an 
increase in the active safety.
ABS is operational every time you start the 
engine. Safe braking, refer to page
Electronic brake-force distribution
The system controls the brake pressure in the 
rear wheels to ensure a stable braking behavior.
DBC Dynamic Brake Control
When the brake pedal is depressed quickly, this 
system automatically generates a maximum 
braking force distribution and thus helps keep 
the braking distance to a minimum during full 
braking. This system exploits all of the benefits 
provided by ABS.
As long as you want full braking to continue, do 
not reduce pressure on the brake.
DSC Dynamic Stability Control
DSC prevents slip at the drive wheels when 
starting off and accelerating. DSC also detects 
unstable driving conditions, such as a fishtailing 
of the vehicle's rear end or the sliding of the 
vehicle on its front wheels. In these circum-
stances, DSC helps keep the vehicle on a safe 
path, within physical limits, by reducing engine 
output and by applying the brakes in individual 
wheels.
The DSC is operational every time you start the 
engine.
The laws of physics cannot be repealed, 
even with DSC. An appropriate driving 
style always remains the responsibility of the 
driver. Do not reduce the additional safety mar-
gin again by taking unnecessary risks.
<
Indicator lamp
The indicator lamp goes out shortly 
after the engine starts.
When the indicator lamp flashes:
DSC is controlling the drive and braking forces.
When the indicator lamp stays lit:
DSC has been switched off with the button.
