When the low tire pressure warning light
illuminates, you must fill the tire to the
proper tire inflation pressure. The Tireand Loading Information label shows thecorrect inflation pressure for the tireswhen they’re cold. “Cold” means yourvehicle has been sitting for at least threehours or driven no more than one mile.

could be an early indicator that your tirepressures are getting low and need tobe inflated to the proper pressure.
