Steps to inflate car tires

1. To start the car with the key, you can turn on the cigarette lighter socket in the ACC position, then press the inflator switch to the "0" position, plug in the power plug, and the indicator light will come on. If the battery is low, it is better to start the engine to make sure the battery has enough power.

2. Place the inflator flat on the ground, the display will show "0.0". If "0.0" is not displayed correctly, press and hold the center yellow button for more than 5 seconds to reset.

3. Unscrew the tire valve cover, place it in place, and then screw the inflator's inflation hose to the tire valve through the connector. The valve must be tightened into place and not run.

4. At this point, the inflator screen displays the current tire inflation pressure. Note the units displayed, including bar, psi, and kPa. You can switch between them by pressing the yellow button. My tire pressure is 28.5 psi, which is below the 30 psi specified in the manual. I need to inflate the tires.

5. Press the key to the right of the yellow button to set the value displayed on the screen to 30 psi, then press the inflator switch to the "1" position and the inflator will start working. The value on the screen will gradually rise to 30, 30.5, and pause for a few seconds before continuing to inflate until the tire pressure stabilizes at 30 psi.

6. Press the inflator switch to the "0" position and unscrew the inflation hose fitting from the tire valve. Move it quickly to prevent the filled air from running out. Then unplug it and screw back the valve cover of the tire.
