How do I activate the Audi A3's automatic emergency brakes?

I recently purchased an Audi A3 and I'm trying to figure out how to activate the automatic emergency brakes. Can anyone provide step-by-step instructions?

To activate the automatic emergency brakes, first make sure the feature is turned on in your vehicle's settings. Then, when driving at speeds below 18 mph, if the car senses an imminent collision, it will automatically apply the brakes to help avoid or mitigate the impact.

You can also activate the emergency brakes manually by pulling on the parking brake handle in the center console. This will engage the brakes on all four wheels.

Keep in mind that the automatic emergency brakes should not be solely relied upon and it's important to always stay alert and attentive while driving.
