The vehicle has been parked with the tires out
of direct sunlight for at least three hours.
R
The vehicle has traveled less than 1 mile
(1.6 km).
The vehicle's tires heat up when driving. As the
temperature of the tires increases, so too does
the tire pressure.
Vehicles with a tire pressure monitoring system:
