My understanding is there are two different systems here. One is headlight leveling which moved the lights up and down. The other is AFS, that moves the lights to the right and left.
If you have the rear of the car fully loaded the leveling system will insure that the lights do not blind oncoming drivers. If you have AFS, the lights will turn to the right and left with the speed of the vehicle and the angle of the steering wheel.
The parts you show are from the leveling system.
Hope that helps.

This is correct, these sensors are for the leveling. AFS refers to the swivel control. That being said in the 2IS, both are controlled by a single computer, so they are somewhat integrated.

There is also the base level that is actually set at the headlight to consider. Adjusting that is the correct way to set base level.
The AFS only turns to the left, not right. And the easiest method of adjusting both head lights equally is to use the rear level adjustment. Doing each head light individually by the book is a very lengthy procedure and not as easy.

AFS turns both ways.
The left headlight turns up to 15 degrees to the left.
The right headlight turns up to 5 degrees to the right.

Personally I find doing it at the headlight easier, but aside from being by the book I can't see a huge difference either way, other than if auto-leveling stopped working, it wouldn't correct it based on the rear sensor adjustment, and also I'm not entirely sure if the auto-leveling system reacts exactly the same way if if thinks the suspension is already loaded/unloaded in the rear as far as road bumps/hills, etc. go. It's probably not a big deal really, I just figure you might as well do it the correct way. All you have to do to get to the adjusters on the headlight is pull off the engine covers anyway, it's like a few clips, versus having to get under the car and adjust the sensor. I never got why that was considered easier.

I've never adjusted my headlights using the screws up front, but remember reading it's somewhat complicated by the fact that there are 2 screws for each headlight and they have to be adjusted together in order to get the lightsjust right. Is that not accurate?
