This initial step can often resolve the warning light if the pressure is simply low. Next, inspect the tires for any visible damage, such as punctures, cuts, or bulges, which could also trigger the warning light. If the tires appear to be in good condition, proceed to reset the tire pressure monitoring system, as outlined in your owner's manual, since sometimes the system may need a refresh after correcting the pressure. Additionally, examine the valve stems for any signs of damage or leaks that could be causing the warning light to activate.
