The 2021 Subaru Ascent is designed with a focus on safety, performance, and comfort. One crucial aspect of vehicle maintenance that often gets overlooked is tire pressure. Proper tire pressure ensures optimal handling, fuel efficiency, and tire longevity. Understanding the recommended tire pressure for various trims and engines of the Ascent can help drivers maintain their vehicle in peak condition.
Maintaining the correct tire pressure is not just about adhering to manufacturer recommendations; it’s also about enhancing safety on the road. Under-inflated tires can lead to poor handling and increased tire wear, while over-inflated tires can result in a harsher ride and reduced traction. Below is a detailed table outlining the recommended tire pressure for different trims and engines of the 2021 Subaru Ascent.
2021 Subaru Ascent Tire Pressure
Tire Pressure Table for Different Trim/Engine
| Trim/Engine | Recommended Tire Pressure (PSI) | Recommended Tire Pressure (BAR) |
|---|---|---|
| Base | 33 | 2.3 |
| Premium | 33 | 2.3 |
| Limited | 33 | 2.3 |
| Touring | 33 | 2.3 |
Resetting Tire Pressure Sensor for 2021 Subaru Ascent
The tire pressure monitoring system (TPMS) in the 2021 Subaru Ascent plays a vital role in ensuring that your tires are properly inflated. When the TPMS light is flashing, it indicates that there’s an issue with the tire pressure or the system itself. Knowing how to reset the tire pressure sensor can help you address these concerns effectively.
Before attempting to reset the tire pressure sensor, it’s crucial to ensure that all tires are inflated to the recommended pressure. This will prevent the TPMS light from reactivating shortly after the reset. Follow these steps to reset the tire pressure sensor:
Steps to Reset Tire Pressure Sensor
- Check the tire pressure of all four tires using a reliable gauge.
- Inflate or deflate the tires as necessary to match the recommended tire pressure.
- Turn the ignition to the “ON” position without starting the engine.
- Locate the TPMS reset button, usually found beneath the steering wheel or in the glove compartment.
- 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. The TPMS light should turn off if the reset was successful.
Tire Pressure Monitoring System Light Flashing
If the TPMS light continues to flash after following the reset procedure, it may indicate a malfunction within the system. Below is a table that outlines potential issues and solutions.
| Issue | Possible Cause | Recommended Action |
|---|---|---|
| TPMS Light Flashing | Low Tire Pressure | Check and adjust tire pressures. |
| TPMS Light Flashing | Faulty TPMS Sensor | Inspect and replace sensor if necessary. |
| TPMS Light Flashing | Dead Battery in Sensor | Replace the battery or sensor. |
| TPMS Light Flashing | System Malfunction | Visit a certified Subaru technician for diagnosis. |
Maintaining proper tire pressure and a functional TPMS is essential for your safety and vehicle performance. If issues persist, consulting a professional is the best course of action.
Importance of Maintaining Proper Tire Pressure
Maintaining proper tire pressure is crucial for the overall performance, safety, and longevity of your 2021 Subaru Ascent. Incorrect tire pressure can lead to various issues that affect not only your driving experience but also your safety on the road. Under-inflated tires can cause poor handling, increased tire wear, and reduced fuel efficiency. Conversely, over-inflated tires can lead to a harsher ride and decreased traction, especially in wet conditions.
Regularly checking and maintaining the correct tire pressure can significantly enhance your vehicle’s performance. It ensures that your tires wear evenly, prolonging their lifespan and saving you money in the long run. Furthermore, proper tire pressure contributes to better fuel economy, which is essential for both your wallet and the environment.
How to Check Tire Pressure
Checking the tire pressure of your Subaru Ascent is a straightforward process. Follow these steps to ensure accurate readings:
- Gather a reliable tire pressure gauge. Digital gauges are often easier to read than manual ones.
- Ensure your tires are cold, as tire pressure can increase with heat from driving.
- Remove the valve cap from the tire you wish to check.
- Press the gauge onto the valve stem firmly to get a reading. Make sure there’s a good seal to avoid air escaping.
- Read the pressure displayed on the gauge. Compare this to the recommended tire pressure listed on the driver’s side door jamb.
- Replace the valve cap securely.
Useful Tips for Maintaining Tire Pressure
To ensure that your tires remain properly inflated, consider the following tips:
- Check tire pressure at least once a month and before long trips.
- Inspect tires for visible signs of wear or damage, such as cracks or bulges.
- Use a tire pressure monitoring system (TPMS) if available, but don’t rely solely on it; manual checks are still necessary.
- Be aware that tire pressure can fluctuate with temperature changes. For every 10°F change in temperature, tire pressure can change by about 1 PSI.
- Rotate your tires regularly to promote even wear and maintain optimal performance.
- When inflating your tires, always use the recommended PSI for your specific trim and load conditions.
By taking the time to check and maintain your tire pressure, you can significantly improve your driving experience while ensuring the safety and efficiency of your 2021 Subaru Ascent.
