When reverse gear is selected, ParkAssist confirms that it is switched on by issuing a short signal tone.
If the vehicle has front ParkAssist, no signal tone will be issued when reverse gear is selected. Instead, the ParkAssist visual display will appear on the central screen of the Porsche communication system.
A detected obstacle is signalled by an intermittent tone. The intervals decrease as the obstacle is approached.
If the distance drops to less than approx. 14 in. (35 cm), a continuous tone sounds.
You can adjust the volume of the signal tones to your own requirements.

Care Required Parking
Even when using ParkAssist, the driver is still responsible for taking due care when parking and when assessing obstacles.
A continuous tone sounds when there is a risk of collision.
Limits of ultrasonic measurement
– ParkAssist cannot detect sound-absorbing obstacles (e.g. winter driving, powder snow),
– sound-reflecting obstacles (such as glass surfaces and flat painted surfaces),
– and very thin obstacles (e.g. thin posts).
Other ultrasound sources (such as the pneumatic brakes of other vehicles and jack hammers) can interfere with the detection of obstacles.
Correct operation is no longer guaranteed if there is a temporary fault (e.g. caused by ice formation or heavy soiling on the sensors).
