Technology for driving comfort and safety

Park Distance Control PDC*

The concept
The PDC assists you with maneuvering in tight
parking spaces. Acoustic signals warn you of
the presence of an object behind your vehi-
cle.To measure the distance, there are four
ultrasonic sensors in either bumper.
However, an acoustic warning does not sound
until an object is closer than approx. 24 in/
60 cm to the corner sensors, or closer than
approx. 5 ft/1.50 m to the center sensors.
PDC is a parking aid that can indicate
objects when they are approached
slowly, as is usually the case when parking.
Avoid approaching an object at high speed, oth-
erwise physical circumstances may lead to the
system warning being issued too
Switching on automatically
With the engine running or the ignition switched
on, the system is activated after approx. 1 sec-
ond when you engage reverse gear or move the
automatic transmission selector lever to
position R. Wait this short period before driving.
Switching off automatically
After approx. 165 ft/50 m of driving or above
approx. 20 mph/approx. 30 km/h, the system
switches off and the LED goes out.
Signal tones
When nearing an object, its position is indicated
correspondingly by an interval tone. As the dis-
tance between vehicle and object decreases,
the intervals between the tones become
shorter. If the distance to the nearest object
falls to below roughly 1 ft/30 cm, then a contin-
uous tone sounds.
An interval tone is interrupted after approx.
3 seconds

> if you remain in front of an object that has
been detected by only one of the corner
sensors
> if you are driving parallel to a wall.
Malfunction
To avoid 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 a high-pressure cleaner, do not spray the
sensors for extended periods of time and only
from a distance of at least 4 in/10 cm.
System limitations
late.<
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 is also sub-
ject to the physical limits that apply to all forms
of ultrasonic measurement, such as those
encountered with trailer towbars and hitches,
thin or wedge-shaped objects, etc. Low objects
that have already been displayed, e.g. curbs,
can disappear again from the detection area of
the sensors before or after a continuous tone
sounds. Higher, protruding objects, e.g. ledges,
cannot be detected. Therefore, always drive
cautiously, otherwise there is a risk of personal
injury or property damage.
Loud sound sources outside or inside the car
can drown out the PDC signal. Therefore,
always drive cautiously, otherwise there is a risk
of personal injury or property
The indicator lamp in the instrument
cluster comes on. PDC is malfunc-
tioning.Have the system checked.
Even with PDC, final responsibility for
estimating the distance between the
damage.<
