Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor (if needed).
Ensure the vehicle is parked on a level surface and the engine is off.

2. Check and Adjust Tire Pressure

Sub-steps:
- Remove valve caps from each tire.
- Use the tire pressure gauge to measure the current pressure of each tire.
- Refer to the sticker located on the driver’s side door jamb for the recommended tire pressure.
- If any tire is below the recommended pressure, inflate it using the air compressor to the correct PSI.
- If any tire is over-inflated, release air until it reaches the recommended level.

3. Reset the Tire Pressure Monitoring System (TPMS)

Sub-steps:
- Turn the ignition switch to the ON position without starting the engine.
- Press the TPMS reset button, which is usually located under the steering wheel or near the driver's side dashboard.
- Hold the button until the tire pressure light blinks three times and then turns off.
- Turn off the ignition and then start the vehicle to check if the light has reset.

4. Final Inspection

Sub-steps:
- Inspect each tire visually for any signs of damage or leaks after adjusting the pressure.
- Reinstall all valve caps securely.
- Ensure that the tire pressure light remains off during the subsequent drive.
