How do I activate the lane departure warning feature on the Audi A6?

I recently purchased an Audi A6 and I am trying to activate the lane departure warning feature. Can someone guide me through the process?

The lane departure warning feature can be activated by pressing the button with the lane marking symbol on the driver's door panel. A green light will indicate when the feature is active.

Alternatively, you can activate the lane departure warning feature through the infotainment system. Navigate to the 'Driver Assistance' menu and toggle the feature on.
