How do I enable the lane departure warning feature on my Audi A7?

I recently purchased an Audi A7 and noticed it has a lane departure warning feature. However, I can't seem to figure out how to enable it. Can anyone walk me through the steps?

To enable the lane departure warning feature on your Audi A7, first locate the button on the dashboard labeled 'Lane Departure Warning'. Press and hold this button for 5 seconds until you hear a beep. The feature should now be activated.

Another way to enable the lane departure warning feature is through the settings menu on your Audi A7's infotainment system. Navigate to 'Vehicle' settings and then select 'Lane Departure Warning'. From there, you can toggle the feature on or off.
