2019 Subaru Tire Pressure
When the tire pressure monitoring system (TPMS) light flashes on your 2019 Subaru, it indicates that there may be an issue with one or more tires or the system itself. Resetting the tire pressure sensor is essential to ensure accurate readings and maintain safety while driving. Here’s how to effectively reset the TPMS in your vehicle.
Steps to Reset Tire Pressure Sensor
- Check Tire Pressure: Before resetting the TPMS, ensure all tires are inflated to the recommended pressure levels as per the tire pressure table.
- Turn on the Ignition: Insert the key into the ignition and turn it to the “ON” position without starting the engine.
- Locate the TPMS Reset Button: The reset button is typically found beneath the steering wheel or on the dashboard. Consult the owner’s manual if you have trouble finding it.
- Press the Reset Button: Hold the reset button until the TPMS light blinks three times, then release it.
- Start the Engine: Turn off the ignition and start the engine. The TPMS light should turn off after a few moments if the reset was successful.
- Drive the Vehicle: Drive for about 10-15 minutes to allow the system to recalibrate.
Tire Pressure Monitoring System Light Flashing
If the TPMS light continues to flash, it may indicate a malfunction in the system. Here are some potential issues and troubleshooting steps:
| Issue | Description | Solution |
|---|---|---|
| Low Tire Pressure | One or more tires are under-inflated. | Check and inflate tires to the recommended pressure. |
| Faulty Sensor | The TPMS sensor in one or more tires may be malfunctioning. | Inspect and replace any faulty sensors. |
| Battery Issues | The battery in the TPMS sensor may be dead. | Replace the sensor battery or the entire sensor if necessary. |
| System Malfunction | The TPMS may have a malfunction due to wiring or software issues. | Consult a professional mechanic for diagnostics and repairs. |
Important Notes
- Regularly check tire pressure, especially before long trips.
- Always refer to the owner’s manual for specific instructions related to your model.
- If the TPMS light remains on after following these steps, seek professional assistance.
Understanding Tire Pressure Maintenance
Maintaining proper tire pressure is crucial for vehicle safety, performance, and fuel efficiency. Under-inflated or over-inflated tires can lead to various problems, including decreased traction, increased tire wear, and reduced fuel economy. Moreover, improper tire pressure can compromise the vehicle’s handling, making it more difficult to control, especially in adverse weather conditions. Regularly checking and maintaining the correct tire pressure can significantly enhance your driving experience and prolong the lifespan of your tires.
How to Check Tire Pressure
Checking tire pressure is a straightforward process. Follow these steps to ensure your tires are properly inflated:
- Gather Tools: You will need a tire pressure gauge, which can be digital or analog, and an air compressor if adjustments are necessary.
- Check When Cold: Measure tire pressure when the tires are cold, ideally before driving. This provides the most accurate reading.
- Remove Valve Cap: Unscrew the valve cap from one tire and set it aside in a safe place.
- Press Gauge: Firmly press the tire pressure gauge onto the valve stem. A hissing sound may occur, but this is normal.
- Read Pressure: Check the gauge reading. Compare it to the recommended pressure listed on the driver’s side door jamb or in the owner’s manual.
- Repeat: Perform the same steps for all tires, including the spare if applicable.
Useful Tips for Maintaining Proper Tire Pressure
To ensure optimal tire performance, consider the following tips:
- Check Monthly: Make it a habit to check tire pressure at least once a month, and before long trips.
- Monitor Temperature Changes: Tire pressure can fluctuate with temperature changes. For every 10°F drop in temperature, tire pressure decreases by about 1 PSI.
- Visual Inspections: Regularly inspect your tires for signs of wear or damage, such as cracks or bulges.
- Use a Reliable Gauge: Invest in a quality tire pressure gauge for accurate readings.
- Don’t Overinflate: Avoid overinflating tires, as this can lead to reduced traction and increased risk of tire blowouts.
- Consult Professionals: If you notice persistent pressure issues or irregular tire wear, consult a professional mechanic for a thorough inspection.
By adhering to these practices, you can enhance your vehicle’s safety, performance, and efficiency while ensuring that your tires remain in optimal condition. Regular attention to tire pressure is a small but significant step in responsible vehicle maintenance.
