Congrats and welcome! Ok i can help a bit. The parking sensors dont detect curbs, youll notice the fronts will beep when your parking head in and aproaching the car in the adjacent spot.when people wall to close in a cross walk they will sound. mine also went off whan a large snowflake whould land on one. So they are mainly for obstuctions. I rubbed a parking block before i knew this. TPS does not display current pressure on 08 just which tires are low or (off). Hope this helps
