-
with CODE (220a) Parktronic System (PTS)
The sensor actuated by the Parktronic control unit (N62) transmits an ultrasonic signal and is ready to receive after a brief delay (time for the diaphragm
movement to decay).
Each sensor receives the echoes of its own ultrasound signals and the echoes of ultrasound signals from adjacent sensors. The distance to the obstacle is
calculated from the journey time of the echoes.
Detection angle:
horizontal:
120 degrees
vertical:
60 degrees
There are several versions of the sensors depending on vehicle model/model year. Different versions of sensors must not be installed together. Faulty
seat or mechanical damage to the sensors or the wrong version of a sensor, can cause malfunctions or incorrect displays.

Function
On all models, except model 163 the function readiness of the Parktronic system (PTS) is signaled by the bright frame of the LCD warning indicator.
In model 163 this is indicated by the first yellow segment of the LED warning display lighting up at half brightness (approximately 50% of maximum
possible brightness).
When an obstacle is approached, one or more segments of the warning indicator light up depending on the distance.
