Your 2019 Kia Sportage TPMS comes equipped with an indicator light that should turn on to tell you when your tire pressure is too low, as well as when it detects a problem in the TPMS system. Your vehicle’s LCD display will also tell you the pressure of each individual tire. You can also adjust what tire pressure unit it displays by entering your user settings—your owner’s manual will lay out the steps for you.
If you’ve never used a tire pressure gauge, they’re generally quite straightforward. All you need to do is unscrew the valve stem cap on your tire, then press the tire pressure gauge onto the valve stem to get your reading. Depending on the gauge, your 2019 Kia Sportage’s tire pressure might display digitally, or you might read it on a marked bar that emerges from the gauge. Once you have your reading, you can add or remove air from your tires as needed.
