Reset the Tyre Pressure Monitor (TPMS)

Last updated: June 8, 2026

If the tyre-pressure warning has come on in your Lexus ES 300h (2018–present) after you’ve adjusted the pressures or changed a wheel, you reset the monitor with the TPMS SET button. Here’s how.

When to Reset

• After checking or adjusting the tyre pressures.
• After changing wheels or tyres, or fitting winter wheels.

Resetting the System

1. Park level and set all four tyres to the correct cold pressures (placard in the driver’s door shut).
2. Switch the ignition on (you don’t need to start the hybrid system).
3. Press and hold the TPMS ‘SET’ button (low on the dash near the steering column) until the TPMS warning light blinks (typically three times), then release.
4. The system learns the current pressures as the new baseline; it finishes after a short drive.

If the Warning Stays On

• Recheck every tyre — one below spec keeps the warning on and blocks the reset.
• Hold the SET button until the light blinks — releasing early cancels it.
• Drive for a few minutes after pressing SET so the sensors report.
• Still showing with correct pressures? A sensor may have a flat battery — look up the code on autodtcs.com.

Frequently Asked Questions

How do I reset the tyre pressure light on a Lexus ES?

Set the pressures, switch on, then press and hold the TPMS SET button until the warning light blinks.

Where is the TPMS SET button?

Low on the dashboard near the steering column — your handbook shows the exact spot.

Why won’t the warning clear?

Usually a tyre still below spec, or the SET button wasn’t held until the light blinked.

Do I need a tool?

No for a normal reset; a tool is only needed if a sensor is replaced.
