How to Change kPa to PSI on a 2019 Subaru Outback
A few weeks back, I was driving through the rugged mountain terrain when my Subaru Outback’s tire pressure warning light flashed on the dashboard, indicating a low tire. As I pulled over to check the tires, I realized the pressure gauge was displaying the pressure in kPa (kilopascals), a unit unfamiliar to me. Frustrated, I had to search for a way to convert the reading to PSI (pounds per square inch), the more commonly used unit here in the States.
Understanding the Conversion: kPa to PSI
kPa and PSI are both units of pressure, but they have different magnitudes. One kPa is equal to 0.145 PSI, meaning that a pressure reading of 100 kPa would be approximately 14.5 PSI. To convert kPa to PSI, you can use the following equation:
PSI = kPa x 0.145For example, to change 200 kPa to PSI:
PSI = 200 kPa x 0.145 = 29 PSIStep-by-Step Guide to Changing kPa to PSI on a 2019 Subaru Outback
-
Access the Tire Pressure Monitoring System (TPMS) Menu: Start your vehicle and wait for the TPMS icon to appear on the dashboard. Use the steering wheel controls to navigate to the TPMS menu.
-
Select the “Units” Option: Once in the TPMS menu, scroll down to find the “Units” option. Press the “OK” button to open the units menu.
-
Choose PSI as the Unit: Use the arrow keys to highlight “PSI” as the preferred unit of measurement. Press the “OK” button to confirm your selection.
-
Reset the TPMS: After changing the units, the TPMS may need to be reset. Use the steering wheel controls to navigate to the “Reset” option in the TPMS menu and press “OK” to reset the system.
-
Check Tire Pressure: Once the TPMS has been reset, use a tire pressure gauge to check the tire pressure in PSI. Ensure the tires are inflated to the recommended pressure as specified in your vehicle’s owner’s manual.
Expert Tips and Advice
- Always consult your vehicle’s owner’s manual for the recommended tire pressure. Over- or under-inflated tires can compromise your vehicle’s safety and performance.
- If you encounter any difficulties changing the units or resetting the TPMS, refer to your vehicle’s owner’s manual or consult a mechanic.
Frequently Asked Questions
Q: Why is the tire pressure displayed in kPa on my Subaru Outback?
A: Subaru Outbacks manufactured for certain markets use kPa as the default unit for tire pressure. This is due to international standards and regulations.
Q: Can I change the units to PSI on a Subaru Outback from any year?
A: The option to change the units from kPa to PSI is typically available on Subaru Outbacks from 2015 onward. Older models may not have this feature.
Q: Is it safe to drive with a tire pressure warning light on?
A: No. Ignoring a tire pressure warning light can lead to under-inflated tires, which can cause poor handling, increased fuel consumption, and potentially dangerous blowouts.
