What are the key safety features of the Audi A6?

I am considering purchasing an Audi A6, and safety is a top priority for me. Can you provide information on the key safety features of this car?

The Audi A6 comes equipped with a variety of advanced safety features, such as adaptive cruise control, lane departure warning, and emergency braking system.

One notable safety feature of the Audi A6 is its pre-sense basic system, which can detect potential collisions and prepare the car by closing windows and tightening seat belts.

Another important safety feature to note is the A6's rear cross traffic alert, which uses sensors to detect vehicles approaching from the side and can assist with parking and exiting parking spaces.
