Solution

1. Preparation

Gather necessary tools: tire pressure gauge, tire inflator, basic hand tools.
Ensure the vehicle is parked on a level surface and the tires are cool.

2. Checking and Adjusting Tire Pressure

Remove valve stem caps from all tires.
Use the tire pressure gauge to measure the pressure in each tire.
Refer to the vehicle's door jamb or owner's manual for the recommended tire pressure.
If any tire is below the recommended pressure, use a tire inflator to add air until the correct pressure is reached.
Recheck the pressure with the gauge to ensure accuracy.
Replace the valve stem caps securely.

3. Inspecting and Repairing Tires

Visually inspect all tires for cuts, punctures, or embedded objects.
If any tire is damaged, remove it from the wheel using a tire iron and jack.
If the tire is repairable (such as a puncture), take it to a professional for a patch or plug.
If the tire is irreparable, replace it with a new tire, ensuring it matches the specifications of the other tires.

4. Resetting the TPMS

After correcting any tire pressure issues, turn on the vehicle.
Navigate to the TPMS reset option in the vehicle settings.
Follow the prompts to reset the TPMS system, which should turn off the warning light.
