Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Wear safety glasses and gloves.

2. Inspect and Inflate Tires

Sub-steps:
- Remove valve caps from each tire.
- Use a tire pressure gauge to measure the pressure of each tire.
- If any tire is below the recommended pressure (found on the driver’s door jamb), inflate it to the correct level.
- Reinstall the valve caps securely after measurement and inflation.

3. Check and Replace TPMS Sensors (if necessary)

Sub-steps:
- Remove the tire from the wheel using a tire machine or manual tools.
- Locate the TPMS sensor on the rim; it is usually attached to the valve stem.
- Use a wrench to unscrew and detach the sensor.
- Replace the sensor with a new one compatible with the model (ensure it’s properly programmed if required).
- Reassemble the tire and wheel, ensuring it is balanced.

4. Reset the TPMS System

Sub-steps:
- Turn the ignition to the "On" position without starting the engine.
- Use the TPMS reset button located beneath the steering wheel or in the glove box (refer to the owner's manual for exact location).
- Hold the button until the TPMS light blinks three times, then release it.
- Start the engine and check if the TPMS light goes out.
