Automatic steering: this is how the parking process works

The Active Parking Assist parking process begins when the vehicle is in front of the parking space indicated by the arrow, facing the direction of travel, and the driver has engaged reverse gear and confirmed an appropriate warning dialogue with the system via the instrument cluster. The driver continues to control the accelerator and brake pedals whilst manoeuvring into the parking space. The Active Parking Assist takes over lateral guidance by controlling the electric steering in accordance with the longitudinal dynamics specified by the driver and the parking course.

The maximum speed of this parking process is limited to 10 km/h. If the speed reaches 7 km/h, a warning appears in the instrument cluster - "Parking Assist only functions up to 10 km/h" - accompanied by a warning tone. The familiar PARKTRONIC function can be used without any restrictions being imposed. The system switches off as soon as the driver intervenes in the automatic steering control process, switches off the system via the PTS (Parktronic Sensor) button, both the driver's seat belt buckle is released and the driver's door opened, or a system error occurs.

The entire PARKTRONIC and Active Parking Assist system comprises the following components:

Control unit
Ten ultrasonic sensors, two of which have an extended range
PTS warning elements on the dashboard and in the roof lining at the rear
PTS button

A maximum of five manoeuvres are allowed (backwards-forwards-backwards-forwards-backwards). The wheels are then straightened out again. The final parking manoeuvre is notified in the instrument cluster with the message "Parking Assist completed", accompanied by a confirmation tone.
