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 this is the case, 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. Also, see our inventory of new Mercedes-Benz vehicles today!

While most of the time it isn’t a problem, it’s just a matter of resetting your TPMS, or Tire Pressure Monitoring System. But most people don’t know how to reset tire pressure light, but with this helpful guide, you’ll do it in a breeze. Or, if you want to save yourself the trouble, visit our dealership’s service centre in Performance Mercedes-Benz and let a technician do this for you! Contact us or drop by for first-class service!

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!

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, but if it doesn’t, use these steps to reset your tire light:

  • Drive at or above 21 km/l to reset the sensor for 10 minutes. This can cause your 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 it, 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 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.
