What is this yellow knob?

Just browsing some used Yarises, spotted this among the photos. This is a 2008 Yaris RS manual 5-door hatchback.

I've got a 2008 5-door automatic LE trim and it has nothing in that location.

Something aftermarket the current owner put in.

^It does look aftermarket, fog lights perhaps. Or ejector seat.

[WeeYari]

It's a RS model so it already had OEM fogs.

[NEexpat]

^Quite correct, I looked right past that. Perhaps something to do with the cord hanging out of the grill, block heater?

[hondajt]

yeah, it looks like a switch for the block heater, you can see it in the first picture.

[IllusionX]

You would typically not need a button for the block heater though.

[NEexpat]

Well whatever it is it certainly isn't trying to be inconspicuous.

I emailed the seller to inquire, but I doubt I'll get a reply back. It's a used car dealer and I didn't say I'm interested in buying the car.

My only guess was that it may be the fog lights, but I imagine that would be on the stalk with the regular headlights. Maybe the original owner is member here and used that for the DIY cruise control :)

It actually may be for adjusting the delay for the wipers. I remember a blue one like that where the owner had wired up an off the shelf time delay module to his wipers.

Nitrous. Definitely nitrous.
Pre-oiler maybe? Does the airbag recall affect the horn function as well? Wonder if the horn wire broke and he replaced it with that instead.

Twist to reveal machine gun hidden in bumper. Push to commence firing.

Ill put my money on the switch activating the inflatable raft under the car in case of massive floods.

Isn't that the Transformer button? Optimus Prime's manservant is a Yaris, no?
