Adaptive Volume Control

virtuous · 09-06-2004, 01:16 AM

Can someone out there help me unsderstand the "Adaptive Volume Control" that my Prius supposedly came with?

I understand it is supposed to adjust the volume of something for road noise, ambient noise, etc. I have found the button that activates/deactivates the AVC, but I notice no difference whatsoever. Does this work only with the voice navigation system, or the bluetooth cell phone capability, or is it supposed to work with the stereo system as well?

Maybe mine is defective...

Thanks in advance.
A-dog out.

i think it is only for the navigation voice. possibly BT/phone as well.

not entirely sure though.

It is supposed to work with the stereo system since it comes with or without the Nav/BT package.

From the manual:

"Automatic sound levelizer (ASL):
When the audio sound becomes difficult to be heard due to road noise, wind noise, etc. during driving, touch the “ASL” switch. The system adjusts to the optimum volume and tone quality according to the noise level. When the system is on, the sound adjustment level is displayed on the screen."

unfortunately some previously advertised features were not included for the U.S. market such as the ASL and DSP for the stereo as well as the tire pressure monitor :?

I'd really love to have a tire pressure monitor!

Page 63 of the Navigation manual states:

Quote:

“Adaptive Volume Control”: If you turn the
“Adaptive Volume Control” on, the volume is
turned up automatically when the vehicle
speed exceeds 50 mph (80 km/h).
To turn the “Adaptive Volume Control” system
on, touch the switch. The indicator will be
highlighted.

This is in a section of the document that is referring to Voice guidance. I'm pretty sure that Automatic sound levelizer is a totally different beast.

I wonder if there is any reason, other than cost, why Toyota would leave these features off? I'd like to have factory installed EV, auto headlights, ASL, and tire pressure monitor.
