The Audi Parking Systems Plus is an Acoustic and Optical Parking System consisting of four ultrasonic sensors, providing front or rear assistance when parking the car. As soon as the distance to an obstacle at the front or rear is closer than a preset minimum, an audible tone as well as a graphical illustration on the MMI Screen provides a warning.
What Are Parking SensorsThe parking Sensors for your vehicle give you an audible notification when you’re backing up to help keep pedestrians and your car safe. We have two styles of backup sensors, one would be with a speaker only and in that situation, you can hide the speaker anywhere you want.Some people hide it under their dash or even under their seat.
