HOW TO RESET TIRE PRESSURE LIGHT

If you've inflated your tires, but your tire pressure light remains on, this means you may have to reset it. The tire pressure monitoring system (TPMS) on your GMC truck or Cadillac is critical to keeping you and your tires safe, so it's important to make sure it's activated and running properly. If you find your TPMS light on but you don't think it should be, take these steps, or bring your vehicle to our tire center at GMC of Billings in Billings, MT.

Steps to Reset Your Tire Pressure Light

Confident that your tires are full at a healthy pressure? Here are some steps you can take to troubleshoot your tire pressure monitor light and reset it.

  • Drive at or above 50 mph for 10 minutes - your sensor should hopefully reset the next time you turn on the car.
  • Starting with the vehicle off, turn your key to the "On" position, but don't start the vehicle. Find the TPMS reset button (check your manual if you need help), and hold it until the tire pressure light blinks three times. Then, start the car and wait 20 minutes for the tire pressure light to reset.
  • Inflate each of your vehicle's tires to exactly 3 PSI over their recommended amount, and then completely deflate them. Include your vehicle's spare tire, as it may also have a sensor in it. After you've deflated each tire, reinflate them to the recommended tire pressure, and check to see if the tire pressure light has been reset.
  • Make sure the vehicle is off, and then disconnect the positive battery cable with a wrench. Then, turn on the car, honk the horn for approximately three seconds. This discharges any power still stored in the vehicle. Afterwards, reconnect the battery, and check to see if you've reset the tire pressure light.
If none of these steps work, schedule an appointment with one of our service technicians. Or, if you're not confident about handling any of these steps, get in touch with us to help you out with service tips. Better to be safe and have a professional, GMC- or Cadillac-certified technician handle your maintenance if you're unsure of what to do.

What if My Tire Pressure Light is Flashing?

A flashing tire pressure light can sometimes be a sign that the battery needs to be replaced, as tire pressure sensors often use the battery. However, a flashing tire pressure light can also signal a problem with one of the sensors.
