Begin by checking the tire pressure in all four tires using a reliable tire pressure gauge, ensuring they are inflated to the levels recommended in your vehicle's manual. This initial step can often resolve the warning light if the pressure is low. Next, inspect the tires for any visible damage, such as punctures or bulges, which could indicate a leak or other issues. If the tire pressure is correct and the tires appear undamaged, consult your vehicle's manual to see if there is a procedure for resetting the tire pressure monitoring system, as this can sometimes clear the warning light after adjustments. Additionally, examine the valve stems for any signs of wear or leaks, as faulty valve stems can also trigger the warning light. If, after completing these checks, the warning light remains illuminated, it may be time to seek professional assistance from a mechanic or tire service center for a comprehensive diagnosis.
