Toyota Prius Forum : “Beeping in Reverse”

their should be a plugin at rear or on transmission that controls this,even tho it i a safty issue from the factory you should be able to disarm it.

dont listen to the guy talking about a plug on the transmission. there isnt one and if you mess with the wrong thing you can get seriously hurt from the high voltage wires. you should go to a toyota dealer and ask them if it can be disabled

IT is probably the backup camera. If you have one. You should go to the Toyota dealer and ask them what it is. Not all Priuses have backup cameras.

Here are a few sites that tell or show you how to disable this feature:

Sure, you can also have the dealer do it.  But where is the fun in that?  and it will cost you a bundle.

Good luck

I have got a Toyota Prius 2009 in France and the step by step instructions don't work unhappily for french cars; but... the instructions for disable the seat belt beep does work; so, is there anybody who could give me an other step by step instructions in order to disable this crazy reverse beep !...
many thanks for your help

Unfortunately, if you're car is anywhere but North America, the fix provided in the link in the previous post from wiki, will not work.  For whatever reason, they have only allowed it to work in the North American cars.  Strange!  I haven't tried the fix from Wiki yet, but plan to try it today.  The beeping sound makes me nuts!
