You need to purchase a tire pressure gauge. Using this, remove the dust cap on the tire valve and press the socket of the gauge firmly onto the open end of the valve. The gauge will show the tire pressure in the tire. After using the gauge replace the dust cap on the valve.
Tire pressure gauges are simple to use. Just take the valve stem off the tire and insert the gauge end into the stem fully. You will then get your accurate tire pressure reading. Just replace the valve stem and you're done.
A Lexus ES 350 tire pressure light will reset on its own. Tire pressure lights will turn off when the tire is at the proper pressure.

Air leaves a tire when the valve is opened due to the pressure difference. Since the tire has more pressure than the air outside, the tire air will escape until the pressure equalizes.
Because the air inside the tire is under pressure. Gas always flows from a region of higher pressure to a region of lower pressure. As the pressure inside the tire is greater than the pressure outside, the air always comes out of the bicycle tyre.
