What is the Lane Departure Warning system in the Audi A3 and how does it work?

I heard that the Audi A3 has a Lane Departure Warning feature. Can you tell me more about it and how it operates?

The Lane Departure Warning system uses sensors to detect lane markings on the road and alerts the driver if the vehicle begins to drift out of the lane.

In case the driver fails to react to the warning, the system can also assist in steering the car back into the lane to avoid potential accidents.

The Lane Departure Warning system is a helpful tool for long highway drives, especially during heavy traffic or poor weather conditions.
