Understanding TPMS in the Infiniti Q50

The Tire Pressure Monitoring System (TPMS) in your Infiniti Q50 is a vital safety feature designed to alert you when one or more tires are significantly underinflated. Proper tire pressure not only improves fuel efficiency and handling but also reduces the risk of blowouts and uneven tire wear. When the TPMS warning light—a yellow or orange symbol resembling a flat tire—appears on your dashboard, it’s your car’s way of saying, “Hey, check your tires!”

But what happens after you’ve inflated your tires to the correct pressure? The warning light might still stay on. That’s where the TPMS reset comes in. Resetting the system tells your car, “Everything’s good now—no need to worry.” However, many Infiniti Q50 owners are stumped when trying to find the reset button or understand how to complete the process. This guide will clear up the confusion and give you everything you need to reset your TPMS with confidence.

Whether you’ve just rotated your tires, replaced a sensor, or simply filled up your tires after a cold night, knowing how to reset the TPMS ensures your Infiniti Q50 operates smoothly and safely. Let’s dive into the details.

What Is TPMS and Why Does It Matter?

How TPMS Works

The TPMS in your Infiniti Q50 uses sensors mounted inside each tire (usually attached to the valve stem) to monitor air pressure. These sensors transmit real-time data to the vehicle’s onboard computer. If the pressure in any tire drops below the recommended level—typically 25% or more below the ideal PSI—the system triggers a warning light on the dashboard.

There are two types of TPMS: direct and indirect. The Infiniti Q50 uses a direct TPMS, meaning each tire has its own sensor that sends accurate pressure readings. This is more reliable than indirect systems, which estimate pressure based on wheel speed differences.

Why Resetting TPMS Is Important

After inflating your tires or performing maintenance, the TPMS may still show a warning because the system hasn’t “learned” the new pressure levels. Resetting the system recalibrates it, ensuring accurate monitoring. Ignoring a persistent warning light can lead to:

• Reduced fuel efficiency due to underinflated tires
• Increased tire wear and risk of blowouts
• Compromised handling and braking performance
• Failed state inspections in regions requiring TPMS functionality

Resetting the TPMS is a simple but essential step in vehicle maintenance. It’s especially important after seasonal tire changes, rotations, or replacing a damaged sensor.

3. Gently pry open the panel using your fingers or a flathead screwdriver (be careful not to break the clips).
4. Inside, you should see a small, round button—this is the TPMS reset button.

Pro Tip: If you can’t find it, consult your owner’s manual. The exact location may vary slightly depending on trim level or regional specifications.

What If There’s No Button?

If you’ve searched and found no physical button, don’t panic. Your Q50 likely uses a digital reset method. This is common in newer models and doesn’t mean the system is broken. We’ll cover the digital reset process in the next section.

How to Reset TPMS on Infiniti Q50 (Step-by-Step)

Method 1: Using the Physical Reset Button (2014–2017)

If your Q50 has a physical TPMS reset button, follow these steps:

Step 1: Inflate All Tires
Before resetting, make sure all four tires are inflated to the recommended PSI. You can find this information on a sticker inside the driver’s door jamb or in your owner’s manual. Typically, it’s around 32–35 PSI for most Q50 models.

Step 2: Turn the Ignition to “ON”
Insert your key and turn it to the “ON” position (do not start the engine). The dashboard lights should illuminate.

Step 3: Locate and Press the Reset Button
Find the TPMS reset button under the dashboard. Press and hold it for about 3–5 seconds. You should see the TPMS warning light blink three times, indicating the system is resetting.

Step 4: Turn Off the Ignition
Release the button and turn the key back to the “OFF” position. Wait a few seconds, then start the engine. The warning light should be off.

Step 5: Test Drive
Drive the car for a few minutes at speeds above 15 mph. This allows the system to relearn the sensor IDs and confirm the reset was successful.

Example: After rotating my tires last winter, the TPMS light stayed on. I followed these steps, and within two minutes, the light disappeared. Simple and effective!

Method 2: Using the Infotainment System (2018–2023)

For newer Q50 models without a physical button, use the touchscreen menu:

Step 1: Ensure Proper Tire Pressure
As always, start by inflating all tires to the correct PSI.

Step 2: Turn the Ignition to “ON”
Turn the key to the “ON” position without starting the engine.

Step 3: Access the Settings Menu
On the infotainment screen, tap “Settings” > “Vehicle” > “Tire Pressure Monitor.”

Step 4: Select “Reset”
Choose the “Reset” or “Initialize” option. The system will prompt you to confirm. Tap “Yes” or “OK.”

Step 5: Wait for Confirmation
The screen will display a message like “TPMS Reset Complete” or “System Initialized.”

Step 6: Start the Engine and Drive
Turn off the ignition, wait 10 seconds, then start the car. Drive for 5–10 minutes to allow the system to relearn sensor data.

Pro Tip: If the menu options are grayed out, make sure the vehicle is stationary and the parking brake is engaged. Some systems require this for safety.

Method 3: Using an OBD-II Scanner

If the above methods don’t work, or if you suspect a faulty sensor, use an OBD-II scanner with TPMS functionality. These tools can reset the system and diagnose issues like dead sensor batteries or signal interference.

Steps:

1. Plug the scanner into the OBD-II port (usually under the dashboard, near the driver’s knee).
2. Turn the ignition to “ON.”
3. Follow the scanner’s prompts to access the TPMS menu.
4. Select “Reset” or “Relearn” and confirm.
5. Wait for the process to complete, then test drive.

This method is ideal for DIYers who want more control or need to troubleshoot persistent issues.

Troubleshooting Common TPMS Issues

• Signal Interference: Metal wheel covers or nearby electronic devices can block sensor signals.

Incorrect Pressure Readings

If the system shows inaccurate readings:

• Ensure the sensors are properly calibrated. Some require a relearn procedure after tire rotation.
• Check for tire damage or leaks that could cause slow pressure loss.
• Use a manual tire gauge to verify the readings against the TPMS display.

“Service TPMS” Message

This message indicates a system malfunction. Possible causes include:

• A faulty control module
• Wiring issues between sensors and the ECU
• Software glitches requiring a dealership update

In such cases, visit an Infiniti service center for diagnosis and repair.

Tips for Maintaining Your TPMS

Check Tire Pressure Monthly

Make it a habit to check your tire pressure at least once a month. Use a reliable gauge and adjust as needed. Remember, pressure drops about 1 PSI for every 10°F drop in temperature.

Reset After Maintenance

Always reset the TPMS after:

• Tire rotations
• Replacing a tire or sensor
• Seasonal tire changes (e.g., winter to all-season)
• Inflating tires after a warning
