If you have power rear hatch and want it to only open 3/4 or whatever, the manual that came with car had no info. I did find the procedure and can verify it works. See attached photo
Well did a search on here and only found a guy unsure how, no solution so thought I’d post the how to help others because my manual just says push the various buttons to open/close but the online updated manual has more detail and is 100’s of pages longer than what came with the car
