If the tyre-pressure warning has come on in your Lexus NX (2014–2021) after you’ve adjusted the pressures or changed a wheel, you need to reset the monitor so it learns the new pressures as correct. On the NX that’s done with the dashboard menu and a reset button. Here’s how.
When to Reset
- After checking or adjusting the tyre pressures.
- After changing one or more wheels or tyres, or fitting winter wheels.
Resetting the System
- Park on a level surface and set all four tyres to the correct cold pressures (placard in the driver’s door shut).
- Switch the ignition on.
- Scroll the multi-information display menu and select ‘Tyre pressure monitoring’.
- Press and hold the TPMS reset button until the TPMS warning light flashes, then release.
- Switch the ignition off, then on. The system stores the current pressures as the new reference.
If the Warning Stays On
- Recheck every tyre — one below spec keeps the warning on and blocks the reset.
- Hold the reset button until the light actually flashes — releasing too early cancels it.
- Still showing with correct pressures? A sensor may have a flat battery or fault — look up the code on autodtcs.com.
Frequently Asked Questions
How do I reset the tyre pressure light on a Lexus NX?
Set the pressures, switch on, select Tyre pressure monitoring in the display, then hold the reset button until the light flashes.
Where is the TPMS reset button?
It’s a small button (often below the steering wheel or on the dash); the exact spot is shown in your handbook.
Why won’t the warning clear?
Usually a tyre still below spec, or the reset button wasn’t held until the light flashed.
Do I need a tool?
No for a normal reset; a tool is only needed when a sensor is replaced and must be registered.
If the warning came on with other lights, decode the code on autodtcs.com.
