Hey I was wondering if anyone could tell me what this is and it's importance? I just noticed it today and all of my google searching has given me nothing.
Thank you so much! I would never have guessed that was the horn! The only reason this came up is because that radiator guard fell off somehow and while reattaching it I noticed the horn and was concerned the wire wasn't connected. I'll look into some gutter guard for sure! Thanks again!Hi, and welcome to Rav4World.
That round thing is the Rav4 Horn. It is a weak-sauce POS that makes a "Meep-Meep" noise when you press in on the center of the steering wheel.
You can upgrade that to a more louder horn - there is several posts on what can and can not be done. I have the WoLo Bad-Boy horn tucked in the large void on the driver's side. I recommend using a relay with this kind of horn as it draws over 20 amps and the fuse can not take it. I have the horn attached to the relay with a 30 amp fuse to the battery.
P.S. I highly recommend getting some gutter guard (pre-painted black from Lowes/Home Depot). and cover the large opening to the radiator. Can be held in with zip-ties. Cut to size with snips as needed.
