Here's the process:
1. Check tire pressure: Use a reliable tire pressure gauge to check the pressure in each tire, including the spare. Inflate tires to the recommended pressure listed on a sticker usually located on the driver's side doorjamb or in your owner's manual. Don't overinflate.
2. Drive the car: After inflating the tires, drive the car for a short distance (a few miles) at a moderate speed. 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, a sensor, or a consistently low tire pressure despite your efforts. If that's the case, you should consult a mechanic or tire professional.
Important Note: Ignoring a low tire pressure light is dangerous. Driving on underinflated tires can lead to poor handling, reduced fuel economy, increased tire wear, and even tire failure. Always address low tire pressure promptly.
