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. (See "warning display, function").
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.

MODEL

140, 163, 168, 202, 203, 208, 210, 215, 220 with CODE (220a) Parktronic System (PTS)

Procedure
The Parktronic system (PTS) control module performs a self-test when the ignition is switched on. It tests the control module, the sensors and the leads to the sensors.

After the self-test, all active warning displays are fully actuated for approx. 2 s, i.e. all the segments and frames of the active warning displays light up.

System in order:
Models 168, 202, 203, 208, 210, 215, 220

The frames of the active warning displays light up.
Model 163

The first elements of the active warning displays light up at half brightness.

Malfunction:
Models 168, 202, 203, 208, 210, 215, 220

All the red segments and the red parts of the frames on the active warning displays light up.
Model 163

All the red segements of the active warning displays light up.

If a warning display receives no valid signals within 1/2 s of the ignition being switched on, the two red segments of the relevant warning display light up, a warning tone (lasting approx. 3 s) is activated and after 20 s the warning display is switched off.

During operation the control module performs system tests at regular intervals in which components of the Parktronic system (PTS) are tested.
