TPMS Monitors

Tire pressure monitoring system. Incorrect air pressure. Button for reset may be in the glove box (that’s where it is in my Jetta).

The PMS thing was an attempt at humor.
What I have learned about these things.....
The rebuild kit is a waste of money, the last one never worked.
It's illegal to remove them, but since I took the tire out of the back of my truck, "the tire store guy had no way of knowing what car it came off of". They became mandatory in 2008.
Breaking the bead with a floor Jack and a ratchet strap is a lot harder than you tube. Could be my low profile tires.
The other 3 will be in the trash soon.
