How do I activate launch control on an Audi R8?

I recently purchased an Audi R8 and I've heard about launch control. How do I activate it and what are some best practices for using it?

To activate launch control on an Audi R8, first put your car in sport mode and turn off traction control. Then hold down the brake and accelerator at the same time until the revs settle at a certain level, indicated by the launch control icon on the dashboard. Release the brake to launch the car and achieve maximum acceleration.

I recommend only using launch control on a track or in a controlled environment. It can drastically reduce the lifespan of your tires and drivetrain. Also make sure your car is warmed up before using it for optimal performance.
