Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor (if needed), and vehicle owner's manual.
Ensure all tires are at the manufacturer's recommended pressure.

2. Inflate Tires

Use the tire pressure gauge to measure the pressure of each tire.
Inflate any tire that is below the recommended pressure using an air compressor.
Retest the tire pressure to ensure it meets specification.

3. Reset TPMS

Turn the ignition to the "On" position without starting the engine.
Press and hold the TPMS reset button located beneath the steering column (may vary by model).
Hold the button until the TPMS warning light blinks three times, then release it.
Start the engine and let it run for a few minutes.
Drive the vehicle at speeds above 15 mph for about 10 minutes to complete the reset.
