Is there a setting to turn this off?

 

There is, but it has to be done my your dealer. You then get just one beep when you put the car in reverse.

 

Man do I wish there was a do it yourself for this!

 

Has anyone tried the Prius way that is on YouTube?

 

I did turn off the reverse beep.

You can DIY with the Carista phone app and a bluetooth OBD Dongle. I use OBDLink LX

It has a paywall but you can get a one week app access for $10.

 

I had the dealer change mine to one beep, it was annoying...

 

Depending on when you purchased your car and if it has the two free dealers visits available to you, you may get to get it done for free.
If you have the option to get it done for free, there may be other options that you may want to consider changing.
If interested, let me know and I might could point you to the list of dealer only "tunable" options.

Would love to get my hands on the list of dealer options. I'm dropping my car off next week for the brake pad TSB so might as well get some other settings changed...

 

P.392 online/downloadable manual...

 

Thank you. I've seen the manual list, but based on comments here, I was hoping for some hidden, secret-handshake features that I can bug the dealer about.
I'll run through the list in the manual and see what I come up with. Thanks guys.

 

I found the list online. It shows all the ones that can be accessed via menus and also the ones that the dealer can change. The reverse beeping is the most annoying. They can also change the seat belt beep. But that doesn’t bother me. People should be buckled up.

 

I had my R beep changed to one by the dealer - no charge.
Had short lane change blinker (turn signal) changed from 3 blinks to 5 at the same time.

 

Does changing to one reverse beep require disabling the front and rear sensors, per my local dealer?

 

All,
There is a form you can fill out and give to your dealer to set up how you wish your car to be customized. I gave this to my dealer after I ordered my LC in February 2018. They customized per my request prior to delivery. I think if you've recently received your vehicle (or have an agreeable dealer) they will do it for free. There are quite a few items that can be changed to suit your preferences.

I've attached the 6 page document for the preferences I had at delivery.

 

Thanks so much for the prompt, thorough response!
