How does the Audi A4 prevent accidents while on the road?

I am planning on purchasing an Audi A4 and safety is my top priority. I want to know what features and technologies are in place to prevent accidents while driving. I am also interested in how these features work and if there are any limitations.

The Audi A4 comes equipped with a variety of safety features such as adaptive cruise control, lane departure warning, and autonomous emergency braking. These features work together to help prevent accidents by monitoring the road and surrounding vehicles, and can even take control of the car if needed to avoid a potential collision.
