Here's what you need to do:
1. Check your tire pressure: Use a reliable tire pressure gauge to check the pressure in each tire, including the spare. The recommended tire pressure is usually found on a sticker located on the driver's side doorjamb or in the owner's manual. Inflate the tires to the specified pressure. Remember to include the spare.
2. Drive the car: After inflating your tires to the correct pressure, drive your car for a short distance (5-10 miles) at normal speeds. This allows the Tire Pressure Monitoring System (TPMS) to recalibrate.
3. Check the light: After driving, check if the low tire pressure light has turned off. If it remains on, there might be a problem with the TPMS system itself, or a sensor might be faulty. In this case, you should take your car to a mechanic or tire shop for diagnosis.
Important Considerations:
* Faulty sensor: If the light stays on even after proper inflation and driving, a sensor may be malfunctioning. These are located in the valve stems of your tires.
* TPMS issues: There might be a more serious issue with the TPMS system itself. Again, professional diagnosis is needed.
* Incorrect tire pressure: Ensure you're using the correct pressure, not just filling the tires to the maximum number on the tire sidewall. The recommended pressure (PSI) is always lower than the maximum.
If the light persists after following these steps, you'll need to seek professional help.
