How to properly check the tire pressure on a Kia Sorento?

I've recently bought a Kia Sorento and I'm not sure how to check the tire pressure. Can someone provide me with instructions on how to properly do it?

Firstly, make sure you have a reliable tire pressure gauge. Then, remove the cap from the valve on one of the tires

Next, place the gauge over the valve and apply pressure until the gauge reads the tire's current pressure.

If the pressure is too low, add air using an air compressor or take it to a gas station. If it is too high, press the metal stem in the center of the valve until you hear air hissing out.
