What is this button please?

[Salinda Wijayabandara]

My Prius C has a button with white dot. but I have no any idea what I can do with this button?

It's hard to make out from the tiny photo, but that button doesn't look factory and more like an aftermarket accessory. Did you buy the car new or 2nd hand ?

According to the user manual, there is no reference for that button being there, so my thoughts would be that it's after market, but for what is a mystery.

I assume you've pressed it. Did it do anything that you could see or hear ??

ARe you able to upload a more close up photo please ?

Hi Salinda, yes if possible try for a better close up Pic of the button, I also could not find any reference to it in the owners manual.

So advise is same as Tony, try pressing it and then check outside the car to see if you can hear or see anything that has changed.

Keep Safe

I presume an aftermarket switch.
