The TPMS (Tire Pressure Monitoring System) sensor button is a crucial feature found in various vehicles, including the Infiniti Q50. This button plays a vital role in recalibrating the TPMS system after making changes to the tires or tire pressure, ensuring accurate monitoring and timely alerts for the driver.
Understanding the TPMS Sensor Button

The TPMS sensor button is typically located to the left of the steering column and is labeled with the TPMS icon. This button serves as the primary interface for resetting the TPMS system, allowing the driver to maintain optimal tire pressure and ensure the safety and efficiency of their vehicle.
Function of the TPMS Sensor Button
The primary function of the TPMS sensor button is to recalibrate the tire pressure monitoring system after making changes to the tires or tire pressure. This recalibration process ensures that the TPMS system accurately monitors the tire pressure and alerts the driver if any tire is underinflated.
Importance of Proper TPMS Calibration
Proper calibration of the TPMS system is crucial for maintaining vehicle safety and fuel efficiency. Underinflated tires can lead to increased rolling resistance, reduced traction, and even potential blowouts, which can compromise the vehicle’s handling and stability. Additionally, underinflated tires can result in decreased fuel economy, as the engine has to work harder to overcome the increased rolling resistance.
TPMS Sensor Button Reset Process
The TPMS sensor button reset process can be performed using two methods: the button method and the display audio method.
Button Method
-
Locate the TPMS Sensor Button: Identify the TPMS sensor button, which is typically located to the left of the steering column and labeled with the TPMS icon.
-
Hold the Button: Press and hold the TPMS sensor button until the tire pressure warning light blinks three times. This indicates that the system has entered the reset mode.
-
Release the Button: Once the tire pressure warning light blinks three times, release the button and start the vehicle.
-
Verify the Reset: The TPMS system will automatically reset within 20 minutes of driving. During this time, the tire pressure warning light may remain illuminated, but it should turn off once the reset is complete.
Display Audio Method
For vehicles equipped with a Display Audio system, the TPMS sensor button reset process may involve navigating through the settings menu to initiate the calibration process. The specific steps may vary depending on the make and model of the vehicle, so it’s essential to refer to the owner’s manual or consult with a professional for guidance.
When to Use the TPMS Sensor Button
The TPMS sensor button should be used in the following scenarios:
-
Adjusting Tire Pressure: After adjusting the tire pressure to the recommended level, use the TPMS sensor button to recalibrate the system and ensure accurate monitoring.
-
Replacing a Tire or TPMS Sensor: When replacing a tire or TPMS sensor, the system needs to be recalibrated to recognize the new component and monitor it correctly.
-
Rotating Tires: When rotating the tires, the TPMS sensor button should be used to ensure the system accurately monitors the new tire positions.
Importance of Proper TPMS Sensor Button Usage
Properly resetting the TPMS system using the TPMS sensor button is crucial for maintaining vehicle safety and fuel efficiency. By ensuring the system accurately monitors tire pressure, the driver is alerted to any underinflated tires, allowing them to address the issue promptly and avoid potential safety hazards or decreased fuel economy.
Conclusion
The TPMS sensor button is a valuable feature in modern vehicles, providing a simple and effective way to recalibrate the tire pressure monitoring system. By understanding the function, location, and reset process of the TPMS sensor button, drivers can maintain optimal tire pressure, enhance vehicle safety, and improve fuel efficiency. Remember to consult the owner’s manual or seek professional assistance if you have any questions or concerns about the TPMS sensor button in your vehicle.
