How do I activate the Audi A5's lane departure warning feature?

I recently purchased a new Audi A5 and I am having trouble activating the lane departure warning feature. Is there a specific setting I need to adjust or a button to press?

To activate the lane departure warning feature in an Audi A5, go to the car's settings and navigate to the 'Driver Assistance' section. Here, you can enable it from the menu.

I had the same issue with my Audi A5. It turns out there is a button on the steering wheel that you can press to toggle the lane departure warning on and off.

In order for the lane departure warning feature to work, you need to be traveling at speeds above 40 mph. Make sure you are on a highway or larger road when trying to activate it.
