How can I activate the automatic emergency braking feature on my Audi A1?

I recently purchased an Audi A1 and noticed it has an automatic emergency braking feature. However, I cannot seem to figure out how to activate it. Can anyone provide step-by-step instructions?

To activate the automatic emergency braking feature, simply press the button located on the center console between the driver and passenger seats. It has an image of a car with brake lights on it. Once activated, the system will detect potential collisions and automatically apply the brakes if needed.
