Solution

1. Preparation

Gather required tools and parts.
Park the vehicle on a level surface and turn off the engine.
Ensure all necessary safety equipment is available.

2. Check and Adjust Tire Pressure

Sub-steps:
- Remove the valve caps from each tire.
- Use a tire pressure gauge to measure the pressure in each tire.
- Inflate any tire that is below the manufacturer-recommended pressure to the correct level.
- Replace the valve caps securely.

3. Inspect Tires and Valves

Sub-steps:
- Visually inspect each tire for punctures, cuts, or bulges.
- Apply soapy water to the valve stems to check for leaks; bubbles will form if there is a leak.
- If any tire is damaged or if a leak is detected, replace the tire or valve stem as necessary.

4. Reset the TPMS

Sub-steps:
- Turn on the ignition without starting the engine.
- Navigate to the vehicle settings on the dashboard display.
- Select the option to reset the tire pressure monitoring system.
- Confirm the reset and wait for the system to complete the process.
