oil drain plug?
 

I've read some posts, and have watched some videos, about changing the oil in my X3 (2007). They all talk about a "latch door" type thing you have to remove (or swing down) to gain access to the drain plug. I can't find that on mine...
Is the picture I've enclosed the correct drain plug (it is 17mm)? I don't want to wind up draining out the transmission fluid or transfer case oil. Thanks!

Never mind...found another oil change link, and that is the oil drain plug.
