The Tire Pressure Monitoring System (TPMS) is a crucial safety feature in modern vehicles, including the Lexus NX. It alerts drivers when tire pressure is low, helping to prevent accidents and improve fuel efficiency. However, there are times when you need to reset or relearn the TPMS, such as after tire rotations, replacements, or sensor changes. This comprehensive guide will walk you through the process for all generations of the Lexus NX.

Understanding TPMS in Lexus NX

Before diving into the reset procedures, it’s essential to understand what TPMS is and how it functions in the Lexus NX:

• TPMS uses sensors in each tire to monitor air pressure
• It alerts drivers when tire pressure is significantly below the recommended level
• The system requires occasional resetting or relearning, especially after tire maintenance

When to Reset or Relearn TPMS

You should reset or relearn your Lexus NX’s TPMS in the following situations:

• After rotating tires
• When replacing one or more tires
• If you’ve installed new TPMS sensors
• When the TPMS light remains on after properly inflating all tires

General TPMS Reset Procedure for Lexus NX

While the exact steps may vary slightly between generations, here’s a general procedure that applies to most Lexus NX models:

1. Ensure all tires are inflated to the pressure specified on the tire placard
2. Turn the ignition to the “ON” position without starting the engine
3. Locate the TPMS reset button (usually under the steering wheel or in the glove compartment)
4. Press and hold the reset button until the TPMS light blinks three times
5. Release the button
6. Start the engine and wait about 20 minutes for the system to refresh

TPMS Reset for First Generation Lexus NX (2015-2021)

For the first-generation Lexus NX, including the NX200t and NX300h, follow these steps:

1. Turn the ignition to the “ON” position (engine off)
2. Using the steering wheel controls, navigate to the Multi-Information Display
3. Select the “Settings” icon
4. Scroll down to find “TPMS”
5. Press and hold the center button to recalibrate the system
6. The TPMS indicator will blink three times to confirm the reset

TPMS Reset for Second Generation Lexus NX (2022-Present)

The process for the second-generation Lexus NX is similar, but with some slight differences:

1. Ensure all tires are properly inflated
2. Turn the ignition to the “ON” position (engine off)
3. Use the steering wheel controls to navigate to the vehicle settings in the instrument cluster display
4. Find and select “TPMS”
5. Press and hold the center button until the TPMS light blinks three times
6. Start the engine and drive for about 10-20 minutes to complete the relearning process

TPMS Relearn Procedure After Sensor Replacement

If you’ve replaced one or more TPMS sensors, you may need to perform a more comprehensive relearn procedure:

1. Use a properly formatted scan tool to register the new sensor IDs via the OBD port
2. Leave the ignition in the “ON” position
3. Activate all sensors using a TPMS activation tool
4. Drive the vehicle for about 20 minutes at speeds above 19 mph to complete the initialization

Troubleshooting TPMS Issues

If you’re experiencing persistent TPMS problems, consider the following:

• Check for leaks or damage in all tires, including the spare
• Ensure all TPMS sensors are functioning correctly
• Verify that no other electronic devices are interfering with the TPMS signal
• If issues persist, consult a Lexus dealer or certified mechanic

TPMS Best Practices for Lexus NX Owners

To maintain optimal TPMS performance:

• Regularly check tire pressure, especially during temperature changes
• Rotate tires according to the manufacturer’s schedule
• Replace TPMS sensors when replacing tires (typically every 5-7 years)
• Keep the TPMS reset procedure instructions in your vehicle for easy reference

The Importance of Proper Tire Pressure

Maintaining correct tire pressure is crucial for several reasons:

• Improved safety and handling
• Better fuel efficiency
• Extended tire life
• Reduced risk of blowouts and accidents

The TPMS in your Lexus NX helps ensure these benefits by alerting you to potential pressure issues.

TPMS Technology Advancements in Lexus NX

Over the years, Lexus has improved the TPMS technology in the NX:

• First-generation models used a direct TPMS with individual sensors in each tire
• Newer models may incorporate more advanced systems with improved accuracy and battery life
• Some recent models allow for tire pressure monitoring through the Lexus smartphone app

Legal Requirements and TPMS

It’s worth noting that TPMS is not just a convenience feature:

• In many countries, including the United States, TPMS is legally required in new vehicles
• Disabling or tampering with the TPMS may be illegal and could affect your vehicle’s warranty
• Always ensure your TPMS is functioning correctly to comply with safety regulations

Common TPMS Myths Debunked

Let’s address some common misconceptions about TPMS:

The Future of TPMS in Lexus Vehicles

As automotive technology advances, we can expect to see further improvements in TPMS for future Lexus NX models:
