AFS is useless, JMHO. I did not benefit from it. It rather harmed me, in Feb 06 I almost had a crash because this headlight that does not shed farther than 50 feet. I went to the service manager with this issue. They checked it and said" we calibrated it and it's fine". I shut up. Six months later the same service manager told me he drove another IS at night and he noticed the same problem. He added they can not do anything, this is the way it was meant to function.
