AFS Adaptive Front-Light System
Anyone have this? It is on the Tech Package for 2009, but then was dropped for 2010. Have you had problems with this system?
I'm leaning toward a 2010 as they aren't that much more than '09s, and the '10's have a better interior and Navigation System.
I live in a very mountainous area filled with winding roads. It seems like this would be a great option for me. Automatically moving headlamps up and down and side to side dependent on terrain.
Any idea if these could be moved from a 2009 to 2010?

So do they move up and down too, like do they aim down when cresting a hill, and up when descending into a valley? I'm wondering why this was drooped, seems like a great feature, especially for mountain driving. You'd think they would bundle it with an "x".
I know there's some kind of pick-up on the steering column. I wonder how much they would cost to add to a 2010? I know you want to sell yours real cheap.

The don't move vertically, only horizontally with steering input. It would be difficult and extremely expensive to add it to later models. There are numerous parts to the system besides just the headlights themselves. It was dropped because many people didn't really care about it and it adds a lot of expense to production cost.

The right beam moves to the right, left beam to the left. They're great for unlit areas.
Right turns at all speeds 0mph or greater. Left beam does not move when you are at a stop, only when moving around 10-15mph.
I have noticed them move vertically too, not exactly sure how that works, it's not auto-leveling like in some cars. Start the car and you can notice the beam adjusting.

Am I just nuts or stupid then? (don't answer that! )
I have an 08 with AFS. I have adjusted the height of my headlight beams with adjustment screws. Mine absolutely do NOT move vertically automatically. They do not adjust based on vehicle height or angle. When I lowered the car, they were aiming too low. I adjusted the beam height manually with the adjustment screws to aim higher. I adjusted them a little too high and the AFS system has not leveled nor adjusted them back, they still aim high. I don't know if this applies only to 08 models or all of them but I'm 100% certain about mine not adjusting vertically automatically. If anyone has different information, please post a link to it or post a video of the vertical adjustment happening automatically.

Got my info straight out of 2008 Coupe service manual:
HEADLAMP AUTO AIMING
Headlamp Auto Aiming Control Description
• Headlamp auto aiming control controls the headlamp light axis height appropriately according to the vehicle
height.
• AFS control unit detects the vehicle condition necessary for headlamp auto aiming control with the following
signals.
- Height sensor signal
- Engine speed signal (received from ECM with CAN communication)
- Low beam status signal and high beam status signal (received from IPDM E/R with CAN communication)
- Vehicle speed signal (received from unified meter and A/C amp. with CAN communication)
• When the operation conditions are satisfied, AFS control unit transmits the aiming motor drive signal for
adjusting the headlamp axis height.
Headlamp auto aiming operation condition
- Headlamp ON
- While the engine running
- Vehicle speed (Control mode is switched according to the driving condition.)
Headlamp Auto Aiming Operation
• AFS control unit calculates the vehicle pitch angle from the height sensor signal. AFS control unit judges the
angle for adjusting the axis gap from the preset position.
CAUTION:
Adjusted axis position may differ from the preset position although the headlamp auto aiming activates
properly if the suspension is replaced or worn.
• AFS control unit controls the headlamp axis by changing the aiming motor drive signal output according to
the vehicle-rearward height when detecting the following vehicle condition. Output is maintained if other condition
than following is detected

Actually, the lights do aim vertically. If you look at the AFS headlights, they do not have height adjustment screws like the non-AFS lights. This is because they have a motor built in to adjust height. The AFS system also has a height sensor in the rear suspension. Depending on the angle of the rear suspension, the AFS adjusts vertical aim accordingly.

I have afs as well as manual adjustment screw. Mine does not move vertically.
Had to adjust them after I lowered my car.

So from what Modme posted it seems that the vertical height adjustment may not work correctly on vehicles that are lowered (the part about suspension replaced or worn). That may explain why mine don't aim themselves lower since they are obviously aimed too high. Or perhaps they are aimed high enough to be out of the range of the auto adjustment.
Thanks for posting that Modme.

for me it is another reason not to do the '10 front-end conversion! and relocating ICC is not possible for me because of the Stillen transmission cooler, so I would have to get rid of the both very nice features...
