Ensure that each tire is inflated to the recommended levels specified in your owner's manual, as improper inflation is a common cause of warning lights. Next, conduct a thorough inspection of the tires for any visible damage, such as punctures, cuts, or bulges, and remove any foreign objects that may be lodged in the treads. If the tire pressure is correct and the tires appear undamaged, consider resetting the tire pressure monitoring system (TPMS) as it may require recalibration. Refer to your owner's manual for specific instructions on how to perform this reset. After making any necessary adjustments, take your Forester for a short drive; this allows the system to register the changes and may turn off the warning light. If the light remains illuminated despite these efforts, it is advisable to consult a mechanic or a Subaru dealership for a comprehensive diagnosis, as there may be underlying issues that require professional attention.

What could cause the tire pressure warning light to remain on in a 2024 Subaru Forester?
