I've been going through the same thing Iris.
My low beams were pointed higher than the high beams should be. I took a look on the back of the headlight for the adjuster bolts. Not there. At least nowhere visible.
So I sat there twisting the damn knobs. I don't have big hands (dammit), but even with my hands I could barely turn the knobs, theirs just no room for your fingers!
I've finally got them where they should be and I've come to the conclusion that in redesigning the headlights for the Gen 3's. They've completely pooched the reflector design. The headlights, even properly aimed, are WAY substandard compared to my Gen 1.
