How to Remove Flat Tire Warning on an Infiniti Q50
< strong >To remove the flat tire warning light on an Infiniti Q50, first check and adjust tire pressure to manufacturer specs. Then, use either a TPMS relearn procedure or a scan tool to reset the system. Always verify pressures with a gauge for accuracy.
This is a comprehensive guide about How to Remove Flat Tire Warning on an Infiniti Q50.
Key Takeaways
- Check Tire Pressure: Use a digital gauge to ensure all tires match the recommended PSI listed in the owner’s manual.
- Relearn Procedure: Most Infinitis require a TPMS relearn—follow the steps in the manual or use a scan tool.
- TPMS Reset Methods: Options include driving the car slowly (some models) or using a professional reset tool.
- Sensor Issues: If a sensor is faulty, replacement may be needed before the warning disappears.
- Prevent Future Warnings: Regularly monitor tire pressure and avoid sudden drops in temperature.

Introduction: Why Does the Flat Tire Light Come On?
The flat tire warning light on your Infiniti Q50 is part of the Tire Pressure Monitoring System (TPMS), which alerts you when a tire’s pressure drops significantly. This isn’t just annoying—it’s a safety feature! Ignoring it can lead to blowouts or uneven tire wear. The good news? Fixing it is usually quick if you know what to do. Whether you need a DIY reset or professional help, this guide walks you through everything.
Step 1: Check Tire Pressure First
Why Accuracy Matters
Even a small pressure change triggers the TPMS. Before diving into resets, grab a digital tire pressure gauge (cheaper than analog ones). Compare readings to the PSI listed on the driver’s door jamb or in your manual. For example, the Q50 might need 34 PSI for regular tires.
How to Adjust Pressure
- Remove the valve cap from each tire.
- Add air at a gas station or use a portable compressor until the gauge matches specs.
- Reattach caps tightly—they help sensors read accurately.
Step 2: Perform a TPMS Relearn Procedure
Method 1: Drive Slowly (For Some Models)
Some Infinitis automatically recalibrate after 5–10 minutes of driving at under 15 mph. Here’s how:
- Fill tires to correct pressure.
- Drive slowly for 10+ minutes while the TPMS learns new data.
- If the light stays on, try Method 2.
Method 2: Manual Relearn with Scan Tool
If driving doesn’t work, you’ll likely need a scan tool. These are available at auto parts stores or mechanics. The process varies by model but generally involves:
- Turning off the engine.
- Connecting the tool to the OBD-II port under the dash.
- Following prompts to “relearn” tire sensors.
Step 3: Troubleshooting Persistent Lights
Sensor Malfunctions
If the light won’t turn off despite proper pressure:
– A faulty sensor might need replacement (check activation tips here)
– Clean debris around the valve stem
– Ensure batteries in wheel-mounted sensors are fresh
When to Call a Pro
If DIY methods fail, visit a shop. They can diagnose deeper issues like:
- Wiring problems in the TPMS module.
- A defective receiver in the car’s computer.
Prevent Future Warning Lights
Regular Maintenance Tips
Stay ahead of the game with these habits:
- Monthly Checks: Even in summer, temperatures affect pressure.
- Before Long Trips: Verify PSI, especially after loading cargo.
- Winter Prep: Cold weather drops pressure; inflate tires higher in fall.
Conclusion: Get Back on the Road Safely
Removing the flat tire warning on your Infiniti Q50 doesn’t have to stress you out. Start with a simple pressure check, then follow the relearn steps. If stuck, a scan tool or mechanic can save the day. Remember, consistent tire care keeps both your Q50 and passengers happy—and safe!

Question?
How often should I check my tire pressure? Monthly is ideal, especially after extreme weather changes.
What if I don’t have a tire pressure gauge?
Most gas stations offer free gauges. Alternatively, buy one online—they’re affordable and reusable.
Can I ignore the flat tire warning?
No. Underinflated tires increase stopping distance and risk blowouts, even at low speeds.
Do all Infiniti Q50s use the same relearn method?
Models vary. Consult your owner’s manual or a dealer for model-specific steps.
Will resetting the TPMS void my warranty?
No. TPMS resets are standard maintenance and don’t affect warranties.
Are there apps that help track tire pressure?
Yes! Apps like TireMinder sync with compatible TPMS systems for real-time alerts.
