1. Inflate Tires: Inflate all your tires, including the spare, to the recommended pressure. You'll find the recommended tire pressure on a sticker located on the driver's side doorjamb or in your owner's manual.
2. Drive the Vehicle: Drive the vehicle for about 10-20 minutes at a speed of at least 20 mph (32 km/h). This allows the TPMS sensors to transmit their readings to the vehicle's computer.
3. Check the Light: After driving, check if the TPMS warning light has turned off. If it remains on, there might be a problem with one or more of your sensors or a persistent low tire pressure issue.
If the light stays on after driving:
* Check Tire Pressure Again: Double-check all tire pressures, including the spare. Ensure they are within the recommended range.
* Check for Damaged Sensors: A damaged TPMS sensor can cause the light to stay on. This usually requires a trip to a tire shop or mechanic for diagnosis and repair.
* Have the System Scanned: A mechanic can use a scan tool to read TPMS sensor data and identify any problems. This will determine if the problem is with a sensor, the TPMS module, or just a faulty reading.
Important Note: Ignoring a TPMS warning light can be dangerous. Low tire pressure affects handling, fuel economy, and can even lead to a blowout. It's crucial to address the issue promptly.
