The Formentor doesn't come with a TPMS for actual readouts of pressure, but instead i guess it uses the ABS or suspension to gauge if the tyre pressure is off.
The other day after going through roadwork I found a screw in the tyre, wen't to a tyre shop immediately and brought my little portable Ryobi electric pump. When arriving at the shop it gave me the "Rear left tyre pressure low" warning. It had only dropped from around 2.6 bar to 2.1 so I was pretty happy with this. Couldn't see or feel anything myself.
Just make sure you go to the infotainment screen when you can tell the system to accept current tyre pressure as standard (after you check the tyre pressure manually, of course).
