The Subaru Legacy is a popular mid-size sedan known for its reliability and performance. One crucial aspect of vehicle maintenance is ensuring that the tires are properly inflated. Maintaining the correct tire pressure not only enhances safety but also improves fuel efficiency and extends tire life. Each trim and engine variant of the Subaru Legacy may have different tire pressure requirements, making it essential for owners to be aware of these specifications.
Proper tire pressure can vary based on factors such as load, driving conditions, and tire type. Below is a comprehensive table detailing the recommended tire pressure for different trims and engine options of the Subaru Legacy. The values are provided in both PSI (pounds per square inch) and BAR (barometric pressure).

Subaru Legacy Tire Pressure Sensor Reset
The tire pressure monitoring system (TPMS) in the Subaru Legacy is designed to alert drivers when tire pressure is low. However, there are instances when the TPMS light may flash or remain illuminated even after correcting the tire pressure. This can indicate that the system needs to be reset. Understanding how to reset the tire pressure sensor is essential for maintaining optimal tire performance and safety.
Steps to Reset the Tire Pressure Sensor
Resetting the tire pressure sensor in your Subaru Legacy can be done easily by following these steps:
- Ensure all tires are inflated to the recommended pressure.
- Turn the ignition to the “ON” position without starting the engine.
- Locate the TPMS reset button, usually found under the steering wheel or in the glove compartment.
- Press and hold the TPMS reset button until the TPMS light blinks three times.
- Release the button and turn off the ignition.
- Start the engine and check if the TPMS light is off.
If the TPMS light continues to flash, further troubleshooting may be necessary.
Tire Pressure Monitoring System Light Flashing
A flashing TPMS light can indicate a malfunction in the tire pressure monitoring system. Here are common reasons for this issue:
| Reason | Possible Solution |
|---|---|
| Low Tire Pressure | Check and inflate tires to the recommended pressure. |
| Faulty TPMS Sensor | Inspect sensors for damage or replace if necessary. |
| Battery Issues | Replace the battery in the TPMS sensor if it’s not functioning. |
| Recent Tire Change | Reinitialize the TPMS after installing new tires. |
Additional Tips
- Regularly check tire pressure at least once a month.
- Use a reliable tire pressure gauge for accurate readings.
- Consult the owner’s manual for specific instructions related to your model.
- If problems persist, consider visiting a certified Subaru technician.
Importance of Maintaining Proper Tire Pressure
Maintaining the correct tire pressure is vital for the overall performance and safety of your Subaru Legacy. Properly inflated tires contribute to better handling, improved fuel efficiency, and a smoother ride. Under-inflated tires can lead to increased wear, reduced traction, and a higher risk of blowouts. Conversely, over-inflated tires can cause uneven wear and a harsher ride.
Regularly monitoring and maintaining tire pressure should be a priority for all vehicle owners. Here are some key reasons why it’s essential:
Benefits of Proper Tire Pressure
- Safety: Adequate tire pressure helps prevent accidents caused by tire blowouts or loss of traction.
- Fuel Efficiency: Correctly inflated tires improve fuel economy, saving you money at the pump.
- Tire Longevity: Maintaining proper pressure extends the life of your tires, reducing the frequency of replacements.
- Environmental Impact: Better fuel efficiency leads to lower emissions, contributing to a healthier environment.
How to Check Tire Pressure
Checking the tire pressure on your Subaru Legacy is a straightforward process. Follow these steps for accurate readings:
- Purchase a reliable tire pressure gauge if you don’t already have one.
- Ensure the tires are cold; measure pressure before driving or at least three hours after driving.
- Remove the valve cap from the tire you want to check.
- Press the tire pressure gauge onto the valve stem firmly to get a reading.
- Note the PSI reading and compare it to the recommended tire pressure, which can be found on the driver’s side door jamb.
- Repeat the process for all four tires.
Useful Tips for Tire Maintenance
To ensure optimal performance and safety, consider the following tips:
- Check tire pressure at least once a month and before long trips.
- Inspect tires for signs of wear or damage, such as cracks or bulges.
- Rotate tires regularly to promote even wear, usually every 5,000 to 7,500 miles.
- Keep a tire repair kit in your vehicle for emergencies.
- Consult your owner’s manual for specific maintenance recommendations.
By adhering to these practices, you can significantly enhance the performance and safety of your Subaru Legacy while ensuring a smoother and more efficient driving experience.
