To reset the TPMS (Tire Pressure Monitoring System) on a Subaru, start by ensuring all tires are inflated to the recommended pressure. Then, drive the vehicle above 20 mph for at least 20 minutes. This process helps the system recalibrate and clear the warning light. If the light remains on, further troubleshooting may be required.
How to Reset the TPMS on a Subaru
Resetting the TPMS on a Subaru can be straightforward if you follow the correct steps. This guide will walk you through the process, ensuring your vehicle maintains optimal performance and safety.
What is TPMS and Why is it Important?
The Tire Pressure Monitoring System (TPMS) is a crucial safety feature in modern vehicles, including Subarus. It alerts drivers when tire pressure is too low, which can lead to poor handling, decreased fuel efficiency, and increased tire wear.
- Safety: Proper tire pressure ensures better traction and handling.
- Efficiency: Correct inflation improves fuel economy.
- Longevity: Maintains tire health and extends lifespan.
Steps to Reset TPMS on a Subaru
-
Check Tire Pressure:
- Use a tire gauge to ensure all tires, including the spare, are at the recommended PSI (usually found on the driver’s side door jamb).
-
Inflate Tires:
- Adjust the tire pressure to the recommended levels. Over-inflation or under-inflation can trigger the TPMS warning light.
-
Drive the Vehicle:
- Drive your Subaru above 20 mph for at least 20 minutes. This allows the sensors to recalibrate and reset the warning light.
-
Manual Reset (if applicable):
- Some Subaru models may have a TPMS reset button located beneath the steering wheel. Press and hold this button until the TPMS light blinks three times, then release it.
Troubleshooting Persistent TPMS Issues
If the TPMS light remains on despite following the reset steps, consider these additional actions:
- Inspect for Tire Damage: Check for punctures, leaks, or damage that may affect tire pressure.
- Sensor Check: TPMS sensors can fail or lose battery power. Visit a professional to test and replace faulty sensors.
- Professional Assistance: If issues persist, a Subaru dealership or certified mechanic can diagnose and resolve complex TPMS problems.
Common TPMS-Related Questions
What Should I Do if the TPMS Light Comes On?
First, safely pull over and inspect your tires. Check for visible damage or low pressure. If everything seems fine, proceed to inflate the tires to the recommended PSI and reset the system.
Can I Drive with the TPMS Light On?
While it is possible to drive with the TPMS light on, it is not advisable. Low tire pressure can compromise vehicle handling and safety, so it’s best to address the issue promptly.
How Often Should I Check My Tire Pressure?
It’s recommended to check tire pressure monthly and before long trips. Temperature changes can affect tire pressure, so more frequent checks may be necessary in extreme weather.
Do All Subarus Have a TPMS Reset Button?
Not all Subaru models come with a manual TPMS reset button. Check your vehicle’s manual for specific instructions related to your model.
How Much Does It Cost to Replace a TPMS Sensor?
Replacing a TPMS sensor can cost between $50 to $100 per sensor, not including labor. Prices may vary based on location and model.
Enhancing Your Subaru Experience
Maintaining your Subaru’s TPMS is part of ensuring a safe and efficient driving experience. For more information on maintaining your vehicle, consider reading about Subaru maintenance schedules or how to improve fuel efficiency. Keeping informed can save time and money in the long run.
Conclusion
Resetting the TPMS on a Subaru is a simple process that involves checking tire pressure and driving the vehicle to recalibrate the system. Regular maintenance and awareness of your vehicle’s needs can prevent TPMS issues from arising. If problems persist, seeking professional help ensures your Subaru remains safe and reliable on the road.
