360 coolant change question

After replacing the coolant, and filling it to the correct level, how many times should I have to add coolant until all the air is completely out of the system? Typically how much coolant do I have to add, total to maintain the correct level? I'm talking about the top off fluid as the air is expelled, not the total fluid in the system.
I went about 300 miles since the fluid replacement and had to add about 1 liter. Is that it, or am I going to have to add more after some hot and cold cycles?
What is typical?
Thanks!

 

I'm not sure how the dealer did it, I hope I don't have a leak? I don't see anything leaking, and there is no evidence of water in the oil, or exhaust smoke. I just assumed that it was a little air because it seemed to have dropped abruptly in the past 1 or 2 hundred miles. I'll check after a few more hot and cold cycles. Keeping fingers crossed...

 

Good news, it seems to have been a little air in the system. The level hasn't dropped in the past 100 miles. I'll keep an eye on it, but I figured it was air since it dropped very abruptly, and it dropped less and less. Plust there was no evidence of leaks or burning coolant.
