What does TPMS mean on my Subaru Legacy?
TPMS stands for Tire Pressure Monitoring System, a feature found in many modern vehicles, including the Subaru Legacy. The TPMS is designed to alert drivers when the tire pressure in one or more of their vehicle's tires falls below a certain threshold, helping to improve safety and fuel efficiency.
Understanding the Tire Pressure Monitoring System (TPMS)
The TPMS in your Subaru Legacy is a safety feature that continuously monitors the air pressure in each of your vehicle's tires. If the pressure in any tire drops below the recommended level, the TPMS will illuminate a warning light on your dashboard, alerting you to the issue. This allows you to address the problem before it becomes a safety hazard or leads to decreased fuel economy.
How the TPMS Works in the Subaru Legacy
- The TPMS in your Subaru Legacy uses sensors installed in each wheel to measure the air pressure in the corresponding tire.
- These sensors transmit the pressure data to a central control module, which continuously monitors the tire pressure levels.
- If the pressure in any tire drops below the manufacturer-recommended level, the TPMS control module triggers the warning light on your dashboard.
- The warning light will remain illuminated until the tire pressure is restored to the proper level.
By alerting you to low tire pressure, the TPMS helps you maintain optimal tire inflation, which can improve your Subaru Legacy's handling, fuel efficiency, and overall safety.
Maintaining Your Subaru Legacy's TPMS
To ensure your TPMS continues to function properly, it's important to regularly check and maintain the proper tire pressure in your Subaru Legacy. You can find the recommended tire pressure levels in your owner's manual or on a placard located in the driver's side doorjamb.
If the TPMS warning light illuminates, you should check the pressure in all four tires and inflate them to the recommended levels. If the light remains on after adjusting the tire pressure, there may be an issue with the TPMS sensors or the system itself, and you should have your Subaru Legacy inspected by a qualified technician.
Why does my Subaru say TPMS?
When the TPMS indicator light illuminates, it means that at least one tire is significantly under-inflated. Improperly inflated tires negatively affects the traction, stability, braking, and steering of your vehicle. Gas mileage can decrease, and the lifespan of all four tires can be shortened due to uneven tire wear.
What is the TPMS light on a Subaru Legacy?
The TPMS light indicates that one or more of your tires on your Subaru is low on pressure. This might be a result of a puncture or a leak, or it could just the result of a big swing in the outside temperature.
How can you tell which TPMS sensor is bad?
Air Filling and Releasing. Fill each tire until it reaches its recommended tire pressure. Then, gently release air from each tire and monitor the car display panel. If you release pressure from one tire and it doesn't trigger the system, it might mean that the sensor is defective.
Is it OK to drive with TPMS light on?
You will not be able to see this damage, which can increase over time. This is why you should maintain proper inflation pressure and try to avoid driving when the TPMS light is on. If you absolutely must drive a short distance on a tire with severely low pressure, drive very slowly and use extreme caution.
Where is my TPMS reset button?
Set the parking brake. Look for a button to the left of the steering column labeled with the TPMS icon if it's there push and hold it until the TPMS indicator in the instrument panel blinks twice.
How do I clear my TPMS warning?
On press the home button on the touch. Screen then touch vehicle settings touch tpms calibration then select calibrate if calibration failed to start appears repeat the previous. Step the calibration.
Why is my TPMS light on but tires are fine?
Either the TPMS units or system are defective, need new batteries, or the tire pressure is too high or too low.
Where is the TPMS reset button on a Subaru?
The TPMS reset button is typically underneath the steering wheel, but double check your owner's manual.
How serious is TPMS light?
Your TPMS light could save your life
Don't ignore it, don't delay dealing with it. Stop driving and get your tire changed. That light is telling you that you're driving a dangerously under-inflated tire. That can cost you anything from a ruined tire to a lost life.
