I've just tried adjusting my headlamps using the rubber knobs identified in this post.
1 I rotated the 'adjusters' as far as they would go to raise the lamps.
2 They rotated through 220 degrees (approx 5/8ths of a complete turn)
3 Went for a test drive
4 There was no effect!
I need to delve deeper as there must be adjusters for left/right adjustment which I can not see/determine. What I can see are plastic hex head bolts (usually what are used to adjust the lamps in other cars) but these may be what are holding the lamps in place. Sometimes some adjustment is given here but the problem is alignment with the bodywork/trim.
Too dark to see
