Lexus uses direct TPMS — inflate to the placard, then press and hold the TPMS reset button (under the steering wheel or in the glovebox) until the light blinks three times.
Why the Lexus tyre pressure light is on
Lexus fits a sensor in each wheel that reports live pressure to the car. The warning appears for a genuinely low tyre, a cold snap dropping all four, or a sensor battery at the end of its 7–10 year life. Because the car stores the pressures you confirm, the reset must be re-run after any deliberate change.
Lexus tyre pressure light reset — step by step
- Set all four tyres cold to the driver's door pillar placard pressures.
- Switch the ignition ON without starting the engine, with the car stationary.
- Find the TPMS reset button — typically below the steering wheel on IS and NX, or inside the glovebox on RX and UX. On newer models it is a menu item: Settings → Vehicle → TPMS → Set.
- Press and hold until the TPMS warning light blinks three times, then release.
- Drive above 20mph for around 20 minutes so every sensor reports and the light clears.

If the light won't go off
If the light flashes for about a minute at every start-up and then stays on, that's a system fault — a sensor is not transmitting. If it comes on steady, the pressures really are low. Note that Lexus hybrids often carry a space-saver or repair kit rather than a spare, so a slow puncture needs sorting rather than ignoring.
What it costs
Reset is free. Sensor replacement £45–£85 per wheel fitted at an independent including programming; Lexus dealers commonly charge £110–£170 per wheel.
Bob's workshop tip
Lexus sensors last a long time, so if the light appears on a car under six years old, look for a real leak before you spend money on sensors. Nine times out of ten it's a valve core or a nail.
