Here's what you should do:
1. Check and Inflate Tires: Use a reliable tire pressure gauge to check the pressure in each tire, including the spare. Inflate them to the recommended pressure listed on a sticker located inside the driver's side doorjamb or in your owner's manual. Don't overinflate!
2. Drive the Vehicle: After inflating the tires, drive the vehicle for a short distance (a few miles) at a moderate speed. This allows the tire pressure monitoring system (TPMS) to recalibrate.
3. Wait for the Light to Turn Off: The low tire pressure warning light should turn off automatically once the system detects the correct tire pressure. If it doesn't turn off after driving for a short time, there might be a problem with the TPMS sensors or a persistent tire pressure issue.
If the light remains on after following these steps:
* Check the Spare Tire: Ensure the spare tire is properly inflated as well. A low spare tire pressure might trigger the system even if your regular tires are fine.
* Consult Your Owner's Manual: Your owner's manual might have more specific instructions for your vehicle's TPMS system.
* Have Your Vehicle Checked by a Mechanic: If the problem persists, a mechanic can diagnose any issues with the TPMS sensors or the system itself. A faulty sensor is a common cause of a persistent warning light.
It's crucial to address the low tire pressure issue to ensure safe driving. Ignoring it can lead to tire damage, reduced fuel efficiency, and compromised handling.
