How to Reset Your Flashing Tire Pressure Light?

Tire Pressure Warning Light_216248072

It’s frustrating to see that after you refill your tires, the TPMS light is on, making you unsure if you even filled your tires properly or if there’s a gash on your tire. If your tire pressure light is still on, it’s a good idea to take your vehicle to get the tire checked and serviced, just to make sure there isn’t a serious problem. More than likely, our mechanics will just need to reset your TPMS (Tire Pressure Monitoring System).

Most people don’t know how to reset a tire pressure light, but with this helpful guide, you’ll do it in a breeze. Take a moment to learn about how to perform a tire sensor reset. And if you want to save yourself the trouble, don’t hesitate to visit the Performance Mercedes-Benz service centre and let a technician do this for you!

What Does the Flashing Tire Pressure Light Mean?

There are many things that make the TPMS light turn on. One of the things you have to keep in mind is that this system uses batteries to keep itself functioning, and when the light turns on, it can mean the battery needs to be replaced. If it’s not your tires and if you’re not sure that it’s your light’s battery, come to our Niagara-area dealership, and we’ll run diagnostics to get to the root of the flashing tire pressure light problem! And if you’re curious about how to reset the TPMS yourself, review our guide on how to perform a tire sensor reset below.

How to Reset Tire Pressure Light

Once you’ve refilled your tire to the appropriate PSI, found on the side of your tire, the flashing tire pressure light should turn off. If your tire sensors don’t reset, follow these steps to reset the TPMS:

  • Drive at or above 21 km/l to reset the TMPS sensor for 10 minutes. This can cause your tire sensor to reset the next time you turn on the car.
  • With the vehicle off, turn the key to the “On” position, but don’t start the car. Hold the TPMS reset button until the tire pressure light blinks three times, then release it. Start the car and wait 20 minutes for the sensor to refresh. The tire pressure monitor reset button is usually located beneath the steering wheel. If you can’t find the TPMS reset button, check the user’s manual.
  • Inflate all tires to 3 PSI over their recommended amount, then deflate them completely. Be sure to include the spare tire, as it may have a sensor as well. Once they’re all deflated, reinflate them to the recommended tire pressure.
  • With the vehicle off, disconnect the positive battery cable with a wrench. Turn the car on and honk the horn for about three seconds. This will discharge any power still stored in the vehicle. Then, reconnect the battery.
  • After reconnecting the battery, your tire pressure sensor should reset, and the tire pressure light should stop flashing. If that’s not the case, reach out to our team for assistance, as your tires are likely improperly inflated or have a defect.
