Automatic Volume on Radio?
I was wondering if there is automatic volume on the radio, that is as the vehicle goes faster the radio volume automatically increases, when you slow down it reduces. I see that under the audio display a label of "ASL", I thought this might mean "Automatic Sound Level" and I selected "ON" but no difference when driving. I had this feature on my Corvette and Aura, maybe it is just GM.
Now before the wise guys start, yes I know how to turn up the volume, I just thought that a "Luxury" vehicle should have this feature, if not no big deal.
Just wondering.

yes, ASL is auto sound levelizer. lol you guessed right.
i dont think it makes that big of a difference either...but i guess it works so so. I think it turns up the bass a little at higher speeds.
notice the bars next to the ASL logo (like a cell phone) when you are driving on the freeway. that means it turned up the volume

It's a very subtle sound leveler. It does work and if you really pay attention to the bars, the speed, and the sound, you can tell the difference.
Having said that, it is not like on a GM car, where it is a very noticeable volume adjustment at any speed. When I travel and rent, the GM cars with this feature adjust the sound from 0 mph to 10 mph to 20 mph, etc.
I'm thinking the Lexus ASL is partially based on ambient noise (and not just speed)?? Your thoughts? Opinions?

I understand that it uses the bluetooth phone microphone and checks the ambient noise level within the cabin. If the ambient noise moves up or down significantly, it adjusts the stereo accordingly. The idea of this is that it should be completely imperceptible to the occupants of the cabin. Lexus are renowned for their low NVH levels so this is why when compared to a GM car, you can't really see it happening.

Good information
Thanks for all the replies, I will check the bar when I drive the vehicle later today and see if it changes. On the GM you can adjust the level from low, medium and high or off which is nice. Again, thanks for the help.
