How does the Audi A6's lane departure warning system work?

I've heard the Audi A6 has a lane departure warning system, but I'm not sure how it works. Can someone explain it to me?

The lane departure warning system in the Audi A6 uses cameras to detect when the vehicle is drifting out of its lane and alerts the driver through visual and audible warnings. It can also apply corrective steering to keep the car in its lane.

The Audi A6's lane departure warning system is a safety feature that can help prevent accidents caused by drifting out of your lane. It's important to still pay attention to the road and not solely rely on this system.

When the lane departure warning system in the Audi A6 detects the vehicle is drifting out of its lane, it will vibrate the steering wheel to alert the driver. This feature can be turned off if desired.
