How do I activate my Audi A8's remote start function?

I recently purchased an Audi A8 and noticed it has a remote start function. How do I activate this feature and what should I be aware of?

To activate the remote start function, press and hold the lock button on your key fob for 3 seconds. You will hear the engine start and the lights will flash, indicating that the remote start has been activated. It is important to note that this feature will only work if the car is in park and all doors are closed.
