Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles if preferred.

2. Inflate Tires

Use an air compressor to inflate each tire to the manufacturer's recommended pressure.
- Sub-steps:
  - Remove the valve cap from each tire.
  - Attach the air compressor nozzle to the valve stem.
  - Inflate the tire and periodically check the pressure with a tire pressure gauge.
  - Replace the valve cap after inflating each tire.

3. Inspect for Leaks

After inflating the tires, inspect for any air leaks.
- Sub-steps:
  - Apply soapy water to the valve stems and tire beads.
  - Look for bubbles indicating air leaks.
  - If found, replace the faulty valve or tire.

4. Reset TPMS

Reset the Tire Pressure Monitoring System if the warning light remains on after adjusting tire pressures.
- Sub-steps:
  - Turn the ignition to the "On" position without starting the engine.
  - Press the TPMS reset button (usually located under the steering column).
  - Hold the button until the TPMS light blinks three times, then release it.

5. Test Drive

Take the vehicle for a short test drive.
- Sub-steps:
  - Observe if the warning light turns off during the drive.
  - Check the handling and stability of the vehicle.
