most new cars tell you which tire is low like rt frt or left rear. your tires should be above 38 psi always. it could be dangerous if its really low so ck asap

thanks, I'll check each tire, since it shows a light with either LOW or FILL NOW, which, I gather, must be an emergency! It just doesn't specify which tire.

it wont tell you which tire, but you should check them all...it is not necessarily dangerous unless it is really low....
