Last updated:
The Mazda CX-30 (DM, 2019–present) uses a direct TPMS with a sensor in each wheel. It 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.
Set the Pressures First
Inflate all four tyres cold to the figure on the driver’s door-pillar label.
How to Clear the Warning
- With the pressures set, turn the ignition on, then off.
- Wait about 20 minutes.
- Start the engine and drive for about 5 minutes above 25 km/h (15 mph).
- The warning light goes out once the system confirms the pressures.
If the Light Stays On
- Re-check every tyre — one slightly low corner keeps the light on.
- 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.
Frequently Asked Questions
How do I reset the tyre pressure light on a Mazda CX-30?
Set the pressures, cycle the ignition, wait ~20 minutes, then drive ~5 minutes above 25 km/h — it relearns on the move.
Is there a reset button?
No — the CX-30’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 the drive 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.
If a fault code is stored, look it up on autodtcs.com. To clear a service reminder, see our CX-30 service reset.
