I have a warning system that tells me a tire is too low. It shows 4 little tire on 2012 Toyota Camry

How do I know which tire is which. They are in a straight line across the screen.

Look in the owners manual!!! That is the best source of info. for your car there is. Check pressure in ALL tires INCLUDING SPARE.
I already checked both the regular manual and the audio manual. They never say which is which.
I don't understand that reply! Have the air pressure checked in ALL of the tires inculding the spare in the trunk and that should take care of the light. Now if one of the tires is extremely low, it may have a leak. Have a service center check this for you.
