The Kia Niro Mk2 (SG2, 2022–present) uses a direct TPMS — a sensor in each wheel — that relearns automatically as you drive once the pressures are right. There’s no reset button or menu step. Here’s how to clear the light.
The amber tyre symbol means one or more tyres has fallen below the pressure the car expects. It is a warning, not a fault: most often a tyre has slowly lost air, the weather has turned colder, or you have just had a wheel off. Because the Niro reads each wheel directly, the cluster can usually show you which corner is low, which makes it quick to put right.
How the Niro’s TPMS Works
Each wheel reports its own pressure, so the dash can show which corner is low. You correct the pressures and the warning clears itself after a short drive.
Because the sensors measure real pressure, there is nothing to “store” and no menu to open — the job is simply to get every tyre to the right figure and let the car re-read them. That is different from the indirect systems on some cars, which have to be told to memorise a new reference from a menu.
Getting Ready
- Set the pressures with the tyres cold — after standing overnight or a short drive of no more than a mile or two. Warm tyres read high.
- Use the figures on the driver’s door-pillar label, matched front and rear to your load.
- If the cluster shows a low corner, note it so you can check that tyre first.
- Have a reliable gauge or a forecourt airline — even 3–4 psi low is enough to trigger the warning.
How to Clear the Warning
- Set all four tyres to the correct pressure (cold) — the figure is on the driver’s door-pillar label.
- Drive for about 10 minutes at a steady speed above 25 km/h (15 mph).
- The system reads the corrected pressures and the warning goes out.
If the Light Stays On
- Re-check every tyre — one slightly low corner keeps the light on.
- Don’t forget the spare if your Niro carries one with its own sensor — a low spare can keep the warning lit.
- Look for a slow puncture — if the same corner keeps dropping over a day or two, a nail or leaking valve is likely, and the light will keep returning until repaired.
- Cold mornings — a tyre set fine in mild weather can read low overnight; top up to the label figure and drive.
- A steady-flashing TPMS light (about a minute at start-up) means a sensor fault — a flat sensor battery, or a sensor not matched after a wheel change — and needs a tyre shop’s tool.
What Happens Next
Once every tyre is right, the light normally goes out during the first few minutes of driving as the sensors report the fresh readings. There is nothing to confirm and no menu to close. If the warning ever comes on again quickly after you have corrected the pressures, treat it as a genuine leak worth inspecting rather than a glitch — a direct system is reporting what it actually measures.
Frequently Asked Questions
How do I reset the tyre pressure light on a Kia Niro?
Set the pressures correctly and drive about 10 minutes above 25 km/h — there’s no button; the direct system relearns on the move. Because each wheel has its own sensor, you don’t store a reference from a menu; you simply correct the pressures and let the car re-read them.
Is there a reset button?
No — the Niro’s direct TPMS clears itself once the pressures are right.
Why won’t the light go out after pumping the tyres up?
Either a tyre is still slightly off, or it needs a few miles to confirm. A persistent flash means a sensor fault.
Do I need a tool?
Not for a normal reset — only if a sensor was replaced or swapped between wheels.
The light is on but the tyres look fine — what now?
Tyres can lose several psi before they look visibly soft, so always check with a gauge rather than by eye. If the cluster names a corner, start there. A tyre that reads a few psi low is enough to light the warning even when it looks normal.
What does a flashing tyre light mean on the Niro?
A tyre symbol that flashes for around a minute at start-up and then stays lit points to a TPMS sensor problem rather than a low tyre — commonly a sensor with a flat internal battery, or one that hasn’t been matched after a wheel change. A tyre shop with the right tool can identify and re-register the sensor.
