tire pressure indicator

I know the top one is the spare. It is ridiculous that it is not in the manual. I had one tire overinflated and the rest were okay. After letting a little out of each one to find the overinflated tire, it is still over filled, but now I have 3 low ones. Grrr.

on my 2008 Highlander Hybrid, the middle tire pressure is the spare and i was told by the friendly local dealer that there was no way of detewrmining the other order as it varied by the valve sensor and each tire rotation changed the order.
