- in area B (20 cm to 100 cm)
The rear bumper PTS sensor unit (A43) detects obstacles:
- in area C (20 cm to 120 cm)
- in area D(20cm to 80cm)

Warning information
The Parktronic control unit actuates the center instrument panel PTS warning indicator (A44/4) or the rear PTS warning indicator (A44/3). Depending on the distance to the obstacle, visual and, if necessary, acoustic warning information is given out.
The acoustic warning signals have different frequencies so that the driver can decide quickly if the obstacle is in front of or behind the vehicle.
The warning signal for the center instrument panel PTS warning indicator (A44/4) has a higher frequency.
The rear PTS warning indicator (A44/3) is deactivated when reversing with trailer (with code (550) trailer hitch). The area in front of the vehicle continues to be monitored.
The trailer is detected via the trailer hitch socket (13-pin) and trailer recognition control unit.
Deactivation
The Parktronic system (PTS) can be switched off and on manually via the PTS OFF switch in the upper control panel control unit, feedback takes place via an LED in the PTS OFF switch.
