General
The Parktronic system (PTS) is an ultrasonic measurement system for detecting the range to an obstruction in critical situations. It assists the driver in parking and maneuvering situations at speeds below 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 displays.

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

The brightness of the warning displays can be adjusted to suit the ambient brightness automatically or manually depending on the model series.

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

The system is active even if it was manually deactivated during the last journey.
