Question regarding AFS option on headlights
How far is the lights supposed to move from left to right and right to left? Mine barely move at all to notice. I just went to my garage and made sure the afs mode was on and turned my steering wheel both ways and could barely notice. My wife has a G35 and her headlights rotate way more than mine. I also had the garage completely dark except for my headlights being on. Just your thoughts, thanks.

I notice mine move more turning left than turning right.
You have to really look for the movement when turning right to see it.
On my father's LS460 you can see the movement really easy.

The IS models are not easily noticeable as other cars, but they do move, and they move while in motion at a certain speed and how much of a turn is being make., the sensor, the computer figures this all out instantly

Yeah it's really not that much of a difference until you make a turn on streets that are literally pitch black. I went through a completely dark tunnel with a turn and it was pretty cool to see the AFS working around the turn!
On the left side of the steering wheel, under the **** that adjusts the brightness of the gauges, you should have the buttons to change settings (circle button with a left and right arrow on both sides). If you have AFS, you can use the arrow keys to go to the AFS option and turn it on or off. Not all models came with AFS tho.

You won't see anything when you're stopped. Lexus AFS is speed sensitive and will move significantly more the faster you are driving.
When making a right turn, the left headlight stays stationary, the right light turns up to 5° to the right.
When making a left turn, the right headlight stays stationary, the left light turns up to 15° to the left.
The minimum vehicle speed to change the swivel is 6 mph (10 km/h) if the steering angle is wide.
The minimum steering angle to change the swivel is 7.5° if the vehicle speed is high.
The AFS ECU calculates the target lighting angle of the LO/HI beam based on the steering angle and the vehicle speed. Then, it actuates the headlight swivel actuators in order to attain the target lighting angle.

here is how to check...
Start your car, look to the left of the steering wheel on the dash, there is a group of buttons with a left and right arrow and a round circular button. click either left or right and watch your instrument panel. you will see it cycle through tire pressure, afs, tachometer, etc.

The AFS sweep on my car is significantly more noticeable when turning left. The sweep on the right is probably less than 5 degrees and in my opinion useless. I wish there was a way to make the right sweep as far as the left. It would seem that the left side should sweep less because our cars are LHD and our lights sweep into oncoming traffic.

IIRC 15* left; 5* right; no movement at low speed (10-15 mph). I thought they did away with AFS in later models--I had a '12 loaner with HID, but no AFS.
