How to Reset Flat Tire Warning on Infiniti Q50: A Step-by-Step Guide

If you own an Infiniti Q50, you may have encountered the flat tire warning light on your dashboard.

This light is part of the Tire Pressure Monitoring System (TPMS), which alerts you when one or more of your tires are low on air pressure and need to be inflated.

In this article, I will explain what the Infiniti tire warning is, how to reset it, and how to troubleshoot some common issues with the TPMS.

What is the Infiniti Tire Warning?

The Infiniti tire warning is a yellow symbol that looks like an exclamation point inside a horseshoe.

It is located on the lower right corner of the instrument panel.

It will illuminate when the ignition is turned on and then go off after a few seconds if the system is functioning properly.

However, if the light stays on or flashes, it means there is a problem with the TPMS or the tire pressure.

The TPMS monitors the air pressure in each tire using sensors mounted on the wheels.

The sensors transmit signals to a receiver module in the vehicle, which then displays the tire pressure information on the vehicle information display.

The TPMS also has a tire inflation indicator feature, which provides visual and audible signals outside the vehicle to help you inflate the tires to the recommended cold tire pressure.

How to Reset Flat Tire Warning on Infiniti Q50

If the flat tire warning light comes on, you should check the tire pressure in all tires (including the spare tire, if equipped) as soon as possible.

You can use a tire pressure gauge or check the vehicle information display for the pressure of each tire.

The recommended cold tire pressure for your vehicle is shown on the Tire and Loading Information label, which is located on the driver’s door jamb.

To reset the flat tire warning light, you need to inflate the tires to the correct pressure and then drive the vehicle at speeds above 16 mph for a few minutes.

The light should go off automatically once the system detects that all tires are properly inflated.

If the light does not go off, you may need to perform a TPMS initialization procedure using a special tool or by visiting an Infiniti dealer.

What is TPMS on Infiniti Q50?

TPMS, short for Tire Pressure Monitoring System, is a safety feature designed to alert you about significant underinflation in your tires, which can lead to unsafe driving conditions.

Insufficient tire pressure can negatively impact various aspects of your vehicle’s performance, including handling, braking, fuel efficiency, and tire longevity.

Furthermore, it heightens the possibility of tire blowouts and accidents.

The TPMS in the Infiniti Q50 comprises four key components: tire pressure sensors, a receiver module, a warning light on the dashboard, and an inflation indicator located on the hazard switch.

Each wheel houses a sensor responsible for measuring the air pressure within the corresponding tire.

The receiver module, situated under the instrument panel, captures signals transmitted by these sensors.

A warning light on the dashboard illuminates if there’s an issue with the TPMS or tire pressure.

For added convenience, the inflation indicator on the hazard switch employs both visual and audible cues outside the vehicle, guiding you to inflate the tires to the recommended cold pressure.

How do I reset my TPMS sensor Infiniti Q50?

If you have replaced or rotated your tires, or if you have installed new wheels or sensors, you may need to reset your TPMS sensor using a special tool or by visiting an Infiniti dealer.

This is because each sensor has a unique identification code that needs to be registered with the receiver module in order for the system to work properly.

To reset your TPMS sensor using a special tool, you need to follow these steps:

  • Turn the ignition switch to ON without starting the engine.
  • Connect the tool to the OBD-II port under the dashboard.
  • Follow the instructions on the tool’s screen to select your vehicle model and year.
  • Press and hold the hazard switch until it flashes twice.
  • Use the tool to scan each sensor in order from front left, front right, rear right, and rear left.
  • Wait for a beep sound after scanning each sensor.
  • Turn off the ignition switch when done.

To reset your TPMS sensor by visiting an Infiniti dealer, you need to bring your vehicle and all four sensors (including any spares) to an authorized service center.

The dealer will use a diagnostic device to register your sensors with your receiver module.

Why is my tire pressure light still on after filling tires Infiniti?

If your tire pressure light is still on after filling your tires, there may be several reasons for this.

  • You did not fill your tires to the correct pressure

Check your Tire and Loading Information label for the recommended cold tire pressure and adjust accordingly.

  • You did not drive your vehicle long enough for the system to recognize the new pressure

Drive your vehicle at speeds above 16 mph for a few minutes until the light goes off.

  • You have a faulty sensor or receiver module

If one or more of your sensors are damaged or have a low battery, they may not send accurate signals to the receiver module.

If your receiver module is malfunctioning, it may not receive or process the signals from the sensors. In either case, you need to have your system checked by an Infiniti dealer.

  • You have a tire puncture or leak

If your tire is losing air due to a hole or a valve stem problem, your light may come on again after filling your tires.

Inspect your tires for any signs of damage and repair or replace them as needed.

Conclusion

The flat tire warning light on your Infiniti Q50 is an important indicator of your tire pressure and your TPMS status.

It can help you prevent tire-related problems and improve your vehicle’s safety and performance.

However, you need to know how to reset it and how to troubleshoot some common issues with the system.

By following the tips and steps in this article, you can keep your tires and your TPMS in good condition and enjoy a smooth and comfortable ride.
