'11 x5 without auto/power tailgate

[Aqua Bliss]

I'm ordering the 35i basic which I just realized does not come with power tailgate. I searched to try to find the answer to these questions but most of the posts are from those that do have the auto tailgate so couldn't find them exactly. Can someone help that does not have auto tailgate answer these questions:

1) Does the button on the key fob still open up the tailgate or does it have to be done manually.
2) Without power tailgate, is there any tailgate height open adjustment in i-Drive? I still don't want it to hit my garage door when I open it.
3) When I open the tailgate, does it go up? Or does it just click open (like a trunk would), and I have to pull it up?
4) If it has to be manually pulled up, can I stop the motion anywhere in between or does it either all the way up or all the way down.

Thanks.
