What is the tire pressure light on a Lexus NX?
The tire pressure light on your Lexus NX is an important safety feature designed to alert you when one or more of your tires are underinflated. This system, known as the Tire Pressure Monitoring System (TPMS), helps ensure your vehicle operates efficiently and safely by maintaining proper tire pressure. In this article, we’ll explore what the tire pressure light means, why it might turn on, and what steps you should take to address it.
What Does the Tire Pressure Light Indicate?
The tire pressure light on your Lexus NX illuminates when the TPMS detects that the air pressure in one or more tires has dropped below the recommended level. This could be due to a variety of reasons, such as a slow leak, a puncture, or even changes in temperature that affect tire pressure. Driving with underinflated tires can lead to reduced fuel efficiency, uneven tire wear, and even potential blowouts, making it crucial to address the issue promptly.
Common Reasons the Tire Pressure Light Comes On
There are several reasons why the tire pressure light might activate on your Lexus NX:
- Temperature Changes: A sudden drop in temperature can cause the air inside your tires to contract, leading to a decrease in pressure.
- Punctures or Leaks: Nails, screws, or other sharp objects can puncture your tire, causing a slow or rapid loss of air.
- Normal Air Loss: Tires naturally lose a small amount of air over time, which can eventually trigger the TPMS light.
- Faulty TPMS Sensor: If the TPMS sensor malfunctions, it may incorrectly signal that your tire pressure is low.
Understanding the cause of the light is the first step in resolving the issue and ensuring your vehicle remains safe to drive.
Steps to Take When the Tire Pressure Light Comes On
If the tire pressure light on your Lexus NX illuminates, follow these steps to address the issue:
- Check Your Tire Pressure: Use a tire pressure gauge to measure the pressure in all four tires. Compare the readings to the recommended levels listed in your owner’s manual or on the sticker inside the driver’s door.
- Inflate Tires as Needed: If any tires are underinflated, add air until they reach the recommended pressure. Most gas stations have air pumps available for this purpose.
- Inspect for Damage: Look for visible signs of punctures, cuts, or other damage. If you find a puncture, you may need to have the tire repaired or replaced.
- Reset the TPMS: After correcting the tire pressure, the TPMS light should turn off automatically. If it doesn’t, consult your owner’s manual for instructions on manually resetting the system.
- Visit a Professional: If the light remains on or you suspect a sensor issue, take your Lexus NX to a trusted auto repair shop for further inspection.
By following these steps, you can quickly and effectively address the tire pressure light and maintain the safety and performance of your vehicle.
Why Proper Tire Pressure Matters
Maintaining the correct tire pressure is essential for several reasons:
- Improved Fuel Efficiency: Properly inflated tires reduce rolling resistance, helping your vehicle achieve better gas mileage.
- Enhanced Safety: Correct tire pressure ensures optimal handling and reduces the risk of blowouts.
- Longer Tire Lifespan: Evenly inflated tires wear more evenly, extending their lifespan and saving you money on replacements.
By keeping your tires properly inflated, you can enjoy a smoother, safer, and more economical driving experience.
Conclusion
The tire pressure light on your Lexus NX is a valuable tool for maintaining your vehicle’s safety and performance. By understanding what the light means and taking prompt action when it illuminates, you can prevent potential issues and ensure your car remains in top condition. If you’re ever unsure about how to handle a tire pressure warning, don’t hesitate to visit a trusted auto repair shop like Kevin’s Autos for expert assistance.

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.
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.
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 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 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.
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.
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 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.
