System components

Below is an overview of important sensors and operating elements:

  • The parking assistance button is the central control panel for the Parking Maneuvering Assistant function (position 8).
  • Two additional ultrasonic sensors in the front bumper measure parking spaces while driving (position 1).
  • The distance from an obstruction is measured by four ultrasonic sensors in the rear bumper panel and four additional ultrasonic sensors in the front bumper panel (positions 11 and 19).
  • Two additional ultrasonic sensors are installed in the rear bumper to precisely detect the size of a transverse parking space during the parking maneuver. The additional ultrasonic sensors measure the distance to detected objects.

     Functional principle

    The system measures potential parking spaces when driving past at a speed below approximately 22 mph (35 km/h) even without the system having been activated. The parking spaces are measured by

     Functional prerequisites
