Tire Pressure Warning Light_216248072


If your flashing tire pressure light persists after inflating your tires to the correct pressure, you’ll probably need to reset it. If your TPMS light is on, and there’s any chance that you’re due for a tire inspection or replacement, explore our tire packages and get in touch with our service department for help near Caledon.

Resetting Your Flashing Tire Pressure Light

Have you properly inflated your tires per the unique recommendations in your vehicle’s owner’s manual? Is your TPMS light still on? If so, follow these steps to learn how to reset your tire pressure light:

  • Drive at or over 80 km h for longer than 10 minutes to reset your sensor. After 10 minutes, you’ll need to restart your car for the sensor to turn off.
  • If the above doesn’t work, Orangeville drivers can turn their vehicle off, turn the key to the “On” position without starting the car, and then hold the TPMS reset button until their tire pressure light flashes three times. You’ll then want to start the car and let it idle for twenty minutes. For the record, most tire pressure reset buttons are underneath the steering wheel, but you can consult your owner’s manual for specifics.
  • The final strategy is to turn your vehicle off, disconnect the positive battery cable with a wrench, turn on the car and press on the horn for three seconds. This should empty out the remaining power in the vehicle. Once you’ve done this, reconnect your battery.

What Does a Flashing Tire Pressure Light Mean?

Your TPMS system uses sensors that monitor the air pressure in your tires. If you’re certain that your tires aren’t under- or over-inflated, If the flashing tire pressure light doesn’t indicate that your tires are under inflated, it likely means that the batteries in your TPMS sensors need replacement.
