Because I feel like mine doesn't. Up until Saturday, I hadn't noticed a bit of difference with it on. But two days ago, my friend was in the car with me and I mentioned to him that I had no idea if it even worked. He pointed out the little ASL bars that increase/decrease, and I was astounded. I still couldn't hear a difference, though. Anyway, for the past two days, I've tried to listen for a change, and haven't noticed a thing. Not only that, but I havent' seen those bars appear since he was in the car. What's the deal?
Here's what I've tried:
-City driving at 30mph
-Highway driving at 70mph
No bars, no change. And yes, it's set to ON.
Any advice? Should I take it to the dealer?

ASL is only supposed to kick in when there's excess noise in the cabin -- for instance, when you're driving with the window down. Vehicle speed doesn’t matter.
And you're not supposed to notice the change. It automatically adjusts the audio to counter-act the excess noise, but in a subtle way.

Speaking of ASL, it would be nice if Lexus included active noise cancellation, as Acura does in the new RL. ANC uses microphones to pick up ambiant noise, and then cancels it by playing it back out-of-phase through the audio system. Supposedly reduces cabin noise by about 10db. (I'm not sure if ANC is active while the audio system is actually being used to play music.)

How is the excess noise detected, though? I mean, if I start screaming in the car, is the ASL going to kick in? And also, I tried driving with the windows down on the freeway today, and though I got the little bars to fluctuate finally, sorta, I didn't notice a single change in volume or tone.

What a salesman told me is that ASL adjusts the volume according to the noise in the cabin, not speed. It is meant to adjust the volume in certain speakers when it detects off balance noise. If one window is cracked, the volume is raised on those speakers to try to balance the sound throughout the whole car. This may be a technological pipe dream, but this is how the salesman explained it to me.
