There is a screen on the nav where u can convert farenheit to celius, mph to kilometers....... The last one is psi. Does this car monitor tire pressure for u?

 

No...it does not do that. I can't see of a way that it can. On the older Toyota Sienna minvans, the car would throw a psuedo-check engine (tire pressure) light stating that there's a tire with low pressure. It didn't check pressure per se....instead, it used the speed sensors to monitor tire revolutions and compared every corner to one another. But it did not monitor pressure.

Like you said, the screen shows conversion.

 

Yeah, it's just kind of calculator, and it can convert "psi" to whatever the metric measure is.

P.S. I wondered the same thing!
