Anyone out there know what the reset button under the dash on the driver side directly above the accelarator pedel is for? I was installing leds in the interior on my 2015 rx350 and on the driver side under dash panel next to the driver footwell light is a button that says reset .

 

I think the TPMS (Tire Pressure Monitor System) reset is down there.

 

I'm ashamed to tell how long it took me to find that button - despite having read the book and reading about it. Now that I've stretched an additional five inches in my arm, I can find it to reset it (did so tonight, in fact, after adjusting the air pressure in my tires) by Braille.
