How to Reset Tire Pressure Light

If your tire pressure light remains on after you’ve inflated your tires, you may have to reset it. Your tire pressure monitoring system (TPMS) is critical to the safety of your vehicle, and it’s important to make sure it’s activated. If you’re running into problems with your TPMS light on, take these steps, or bring your vehicle to the service center at Mercedes-Benz of Kansas City near St. Louis, MO.

Resetting Your Tire Pressure Light

After you properly inflate your tires, the tire pressure light should go off on its own. If it remains on, there are a few actions you can take:

• Drive at or above 50 mph 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.

What Does a Flashing Tire Pressure Light Mean?

Tire pressure sensors often use a battery, and a flashing tire pressure light can often be a sign that the battery needs replaced. It could also indicate a problem with one of the sensors.
