General 

The Parktronic system (PTS) is an ultrasound measuring system for measuring the distance to an obstruction in critical driving situations. It assists the driver in parking and maneuvering situations at speeds < 15 km/h.

The sensors in the front and rear bumpers emit ultrasound signals which are reflected by an obstacle in the detection range. The echoed ultrasound signals are received by the sensors and their journey time is measured.

The control module uses the journey time of the echo to calculate the distance between the vehicle and the obstacle, and actuates the warning indicators.

The distance between the vehicle and the obstacle is indicated to the driver visually and acoustically.

The brightness of the warning indicators is adapted to the ambient brightness (see "Warning indicator, function").

The Parktronic system (PTS) is activated when the ignition is switched on.
