Using a reliable tire pressure gauge, ensure that each tire is inflated to the manufacturer's recommended PSI levels, as incorrect pressure can trigger the warning light. Next, visually inspect the tires for any signs of damage such as punctures, cuts, or bulges, which could indicate a loss of pressure. If the tires appear to be in good condition, attempt to reset the tire pressure monitoring system, as this can sometimes clear false alerts. Additionally, examine the valve stems for any leaks or damage, as faulty stems can also lead to air loss. If these initial steps do not resolve the issue, it may be necessary to consult a mechanic for a more detailed diagnosis, as they can utilize specialized tools to identify underlying problems.
