What safety features does the Audi A4 have?

I'm looking into purchasing an Audi A4, and safety is a top priority for me. Can anyone tell me what safety features this car has?

The Audi A4 comes equipped with a number of standard safety features, including electronic stability control, anti-lock brakes, and a rearview camera. It also has optional features such as blind spot monitoring and rear cross-traffic alert.

One of the standout safety features of the Audi A4 is its pre-sense city system, which can detect potential collisions at speeds up to 52 mph and automatically apply the brakes.
