How do you activate regenerative braking in the Audi e-Tron?

I've been driving my new Audi e-Tron and I noticed that it has regenerative braking capabilities. How do I activate this feature while driving?

To activate regenerative braking in your Audi e-Tron, simply press down firmly on the brake pedal. This will engage the regenerative braking system and allow the vehicle to convert kinetic energy into electrical energy, powering the battery.

You can also activate regenerative braking by using the 'S' mode on the gear selector. In this mode, the vehicle uses regenerative braking as soon as you lift your foot off the accelerator pedal.
