How do I activate the lane departure warning in my Audi A6?

I recently bought an Audi A6 and noticed that it has a lane departure warning feature. However, I can't seem to find how to activate it. Can someone guide me through the steps?

To activate the lane departure warning in your Audi A6, first make sure the vehicle is in motion. Then, look for the button labeled 'Lane Assist' on the center console. Press and hold the button until the indicator light turns on.
