What is the tire pressure light on a Lexus NX?
The tire pressure light on a Lexus NX is an important indicator that alerts the driver to potential issues with the vehicle's tire pressure. This light, also known as the Tire Pressure Monitoring System (TPMS) light, is designed to inform the driver when the tire pressure in one or more of the vehicle's tires falls below the recommended level.
What is the Tire Pressure Monitoring System (TPMS)?
The Tire Pressure Monitoring System (TPMS) is a safety feature installed in modern vehicles, including the Lexus NX. This system uses sensors located in each tire to continuously monitor the air pressure. When the pressure in one or more tires drops below a certain threshold, the TPMS light on the dashboard illuminates to warn the driver.
Why is Tire Pressure Important?
Maintaining the correct tire pressure is crucial for several reasons:
- Safety: Underinflated tires can affect the vehicle's handling, braking, and stability, increasing the risk of accidents.
- Fuel Efficiency: Properly inflated tires can improve fuel economy by reducing rolling resistance.
- Tire Wear: Underinflated tires wear out more quickly, leading to the need for premature tire replacement.
By alerting the driver to low tire pressure, the TPMS light helps ensure the vehicle is operating safely and efficiently.
What to Do When the Tire Pressure Light Illuminates
When the tire pressure light on your Lexus NX illuminates, it's important to take the following steps:
- Check the Tire Pressure: Use a tire pressure gauge to check the air pressure in each of the vehicle's tires. Compare the readings to the recommended tire pressure, which can be found in the owner's manual or on a placard located in the driver's side doorjamb.
- Inflate the Tires: If the tire pressure is low, use an air compressor to inflate the tires to the recommended level.
- Reset the TPMS Light: After inflating the tires, the TPMS light may remain illuminated. Consult the owner's manual for instructions on how to reset the TPMS light.
- Monitor the Tires: Continue to check the tire pressure regularly and address any issues promptly to ensure the safety and performance of your Lexus NX.
By understanding the purpose of the tire pressure light and taking the appropriate actions when it illuminates, you can help maintain the safety and efficiency of your Lexus NX.
Where is the tire pressure sensor reset button located?
Set the parking brake. Look for a button to the left of the steering column labeled with the TPMS icon if it's there push and hold it until the TPMS indicator in the instrument panel blinks twice.
Why is my tire pressure ok but the warning light still on?
One of the most common reasons for a TPMS light staying on despite the tires being properly inflated is a sensor malfunction. TPMS sensors are typically located inside the tire and can wear out or become damaged over time, particularly if you've hit a curb, driven through a pothole, or been off-road.
Can I still drive with a tire pressure light?
This is why you should maintain proper inflation pressure and try to avoid driving when the TPMS light is on. If you absolutely must drive a short distance on a tire with severely low pressure, drive very slowly and use extreme caution. The tire should be inflated or changed before driving anywhere.
Why is my tire pressure light on when my tires look fine?
The causes can be a malfunction, or the weather changes. Other reasons why your TPMS light may still be blinking is because your tire may be damaged, or you might have gotten a recent tire replacement. Overall, the reasons can be vast, which is why it is best to take your car to a technician for professional diagnosis.
Why is my tire pressure light on but my tires are filled?
One of the most common reasons for a TPMS light staying on despite the tires being properly inflated is a sensor malfunction. TPMS sensors are typically located inside the tire and can wear out or become damaged over time, particularly if you've hit a curb, driven through a pothole, or been off-road.
Why is my car saying low tire pressure if there is nothing wrong?
Very commonly, this is the case of a failed tire pressure sensor. There is one located inside each tire as part of the valve stem. If you just recently had tires installed, there's a good chance on of these sensors was damaged during the tire removal or install process.
Why is my tire pressure light still on after filling tires?
If your light stays on after you fill your tires, the system is probably having trouble detecting the correct levels. However, if you're facing a flashing tire pressure light, you might be dealing with a broken sensor, or with a dying battery.
Where is my tire pressure reset button?
Set the parking brake. Look for a button to the left of the steering column labeled with the TPMS icon if it's there push and hold it until the TPMS indicator in the instrument panel blinks twice.

Method 3: Using the Infotainment System
- Turn on the vehicle and access the main menu on the infotainment screen.
- Navigate to the “Vehicle” or “Settings” section, where you'll find the “Tire Pressure” menu.
- Select “Reset” or “Reinitialize” the TPMS.
Why is my tire pressure light on when my tires are fine Lexus?
It's possible that the car's Tire Pressure sensor could fail because of its age. If that happens, it needs to be fixed when you see it. If the sensor fails, you will have to monitor the Tire Pressure, and it might draw some focus away from the driver.
