Don't know if I have the tire pressure monitoring or not. I didn't specifically ask for it, so unless it is standard, I don't have it.

There was no warning light. Don't those sensors look for DIFFERENCES in tire pressure among the four tires, rather than look for some specific minimum pressure threshold? The tires were very uniform in pressure when I checked them this morning. They were all kind of in between the 26 psi mark and the 27 psi mark. That's what makes me think they were set that way.
