    I don't believe I've ever heard my used Prius make the noise.
    I found the AVAS emitter under the plastic trim cover at the front of the engine compartment.
    I removed the 5 trim cover clips (they all broke) and removed the cover.
    The AVAS (Approaching Vehicle Audible System) is on the driver's side.
    It is behind the grill but in front of the radiator.
    The release tab for the electrical harness plug, as I recall, is facing the grill.
    Press it with one hand while wiggling the plug with the other hand to release it.
    Mine looked unremarkable, so I don't know why the volume is so low.
    (I may have heard it once, but was barely audible.)

    Anyone have any ideas?

    might be adjustable, idk, but there's a federal minimum. many have never heard it, you need to be near asomething to reflect the sound with the window down.
    and some of us have hearing loss :cool:
