Solution

1. Preparation

Ensure the vehicle is parked on a flat, stable surface.
Turn off the engine and ensure all doors are closed.
Gather necessary tools:
- Tire pressure gauge (if needed)

2. Inflate Tires

Use a tire pressure gauge to check each tire's pressure.
Inflate any under-inflated tires to the manufacturer’s recommended pressure (usually found on the driver's side door jamb).
Confirm that all tires, including the spare, are at the correct pressure.

3. Reset TPMS

Locate the TPMS reset button: This is usually found underneath the steering wheel or near the driver's side dashboard.
Turn on the ignition: Do not start the engine; just turn the key to the "On" position.
Press and hold the TPMS reset button: Hold it until the tire pressure light blinks three times, then release it.
Turn off the ignition: Wait a few seconds and then turn the ignition back to the "On" position.
Check the tire pressure light: The light should turn off after a few moments if the system has been reset successfully.
