Question,
My low tire pressure is on and I was trying to figure out which tire is low. When I try to check on the dash, all 4 tires are blank. I tired to reset it but to no avail. Anything I'm doing wrong. I'm still learning how to use the car

 

Good old tire pressure gauge!
You generally have to roll a bit for the pressures to show in the dash. So if you can't see a flat one, take a quick drive and it should show.

 

So the car has to be in "motion" for the tire pressure to show on the dash?

 

No, but it should help your situation

 

it didn't work, still no reading. I'm taking my car to the dealer (warranty will cover this)
