The tire pressure monitoring system, or TPMS, is a technology in all Mercedes-Benz today that alerts you when one or more of your tires are underinflated. It is a vital safety feature and must remain activated at all times. To naturally reset the light, you should manually check your tires and fill the underinflated ones with air.
How Much Air Should I Add to My Tires
To find the manufacturer’s recommended psi range, you should look in the driver’s door jamb. There is usually a sticker labeling the front and rear tire specifications. If you can’t find it, you can always find the information you need in the owner’s manual.
What to Do Next to Reset the Tire Pressure Light
Once you have filled your Mercedes-Benz tires with the proper air, the light should go off on its own. You can also do the following steps:
- Drive at a higher speed
- Turn the car off and then back on, but not all the way to start the vehicle completely. Hold the TPMS reset button, located beneath the steering wheel in some models, until the light flashes 3x. Start the vehicle completely, and it should reset within 15-20 minutes.
- Disconnect the positive battery cable, and turn the car on. Press on the steering wheel to use the horn, and then reconnect the battery cable.
What If It Continues to Flash
A blinking TPMS light means that it is not tire-related at all. In fact, there’s a likelihood that there is something wrong with the tire pressure sensors.
