You can also have the system show distances
to objects on the Control Display. Objects that
are farther away are already shown there before
a signal tone sounds.

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 pro-
vided, there is a blind spot in which objects can
no longer be detected. The system's detection
of objects is also subject to the physical limits
that apply to all forms of ultrasonic measure-
ment, such as those encountered with tow bars
and trailer couplings, thin or wedge-shaped
objects etc. Low objects already displayed, e.g.
the curb, can also disappear from the detection
area of the sensors again before or after a con-
tinuous tone already sounds. Higher, protrud-
ing objects, e.g. ledges, cannot be detected.
For this reason, drive with care; otherwise, there
is a danger of personal injury or property dam-
age.
Loud sources of sound, inside and outside the
vehicle, could drown out the PDC signal tone.<
