The 2010 Subaru Impreza is a compact car known for its reliability and performance. One of the critical aspects of maintaining any vehicle is ensuring that the tire pressure is at the recommended levels. Proper tire pressure not only enhances safety but also improves fuel efficiency and prolongs tire life. Understanding the specific tire pressure requirements for different trims and engine types is essential for any owner.
Maintaining the correct tire pressure is vital for the overall performance of your Subaru Impreza. Under-inflated tires can lead to decreased handling, increased wear, and potential blowouts, while over-inflated tires can cause a harsh ride and reduced traction. Below is a detailed table outlining the recommended tire pressure for various trims and engine configurations of the 2010 Subaru Impreza.

2010 Subaru Impreza Tire Pressure Sensor Reset
When the tire pressure monitoring system (TPMS) light flashes on your 2010 Subaru Impreza, it indicates that there may be an issue with one or more of your tire pressure sensors. This could be due to low tire pressure, a malfunctioning sensor, or the need to reset the system after adjusting the tire pressure. Knowing how to reset the tire pressure sensor is crucial for maintaining your vehicle’s performance and safety.
Steps to Reset the Tire Pressure Sensor
- Check the tire pressure in all four tires using a reliable tire pressure gauge.
- Inflate or deflate the tires to the recommended pressure as specified in the owner’s manual.
- Turn the ignition key to the “ON” position without starting the engine.
- Locate the TPMS reset button, usually found beneath the steering wheel or on the dashboard.
- Press and hold the TPMS reset button until the TPMS light blinks three times, then release it.
- Start the engine and wait for a few minutes to see if the TPMS light turns off.
Common Issues with TPMS Light
If the TPMS light continues to flash after resetting, it may indicate other issues. Here are some common causes:
| Issue | Description |
|---|---|
| Low Tire Pressure | One or more tires may be significantly under-inflated. |
| Faulty Sensor | A tire pressure sensor might be malfunctioning or damaged. |
| Battery Issues | The battery in one of the tire pressure sensors may be dead. |
| Temperature Changes | Rapid temperature changes can affect tire pressure and trigger the TPMS light. |
Additional Tips for TPMS Maintenance
- Regularly check tire pressure, especially with temperature changes.
- Replace tire pressure sensors every 5-7 years to ensure accuracy.
- Use a high-quality tire pressure gauge for accurate readings.
- Consult a professional if the TPMS light does not turn off after resetting.
Importance of Maintaining Proper Tire Pressure
Maintaining proper tire pressure is crucial for the overall performance and safety of your vehicle. For the 2010 Subaru Impreza, correct tire pressure not only enhances handling and stability but also contributes to fuel efficiency. Under-inflated tires can lead to poor traction, increased stopping distances, and uneven tire wear, while over-inflated tires can cause a harsh ride and increase the risk of a blowout. Regularly monitoring and adjusting tire pressure can significantly extend the life of your tires and improve your driving experience.
How to Check Tire Pressure
Checking tire pressure is a straightforward process that should be performed at least once a month and before long trips. Follow these steps for accurate readings:
- Purchase a reliable tire pressure gauge if you don’t already have one.
- Ensure that the tires are cold; tire pressure increases with heat from driving.
- Remove the valve cap from the tire you wish to check.
- Press the tire pressure gauge onto the valve stem firmly to get a reading.
- Note the PSI reading displayed on the gauge.
- Replace the valve cap securely after checking.
Compare the reading to the recommended tire pressure listed in the owner’s manual or on the driver’s side door jamb. If the pressure is too low or too high, make the necessary adjustments.
Useful Tips for Maintaining Proper Tire Pressure
To ensure optimal performance and safety, consider the following tips:
- Check tire pressure when tires are cold, ideally in the morning before driving.
- Use a digital or dial gauge for accurate pressure readings.
- Keep a portable air compressor in your vehicle for quick inflation when needed.
- Inspect tires regularly for signs of wear, damage, or punctures.
- Rotate tires every 5,000 to 7,500 miles to promote even wear.
- Be aware of seasonal changes; tire pressure can drop in colder temperatures.
- Monitor the TPMS light; if it activates, check tire pressure immediately.
By following these guidelines, you can ensure that your 2010 Subaru Impreza operates safely and efficiently while prolonging the lifespan of your tires.
