When the tyre-pressure warning light comes on in your Mazda 3 Mk3 (BM/BN, 2013–2018), it usually just means the system needs to store your current pressures as the new reference after a check, top-up or wheel change. The Mazda 3 resets with a button. This guide shows how.
When to Reset
- After checking or adjusting the tyre pressures (including seasonal changes).
- After changing or repositioning one or more wheels or tyres.
- After disconnecting or reconnecting the battery.
Set Your Pressures First
The reset stores whatever pressures are in the tyres at that moment, so they must be correct first. Park on level ground and set all four (cold) to the figures on the placard in the driver’s door aperture, using the laden column for a full load. Never reset with a tyre already low.
How to Reset the Mazda 3 TPMS
- Make sure all four tyres are at the correct cold pressure and the car is on level ground.
- Turn the ignition on.
- Find the TPMS set button (low on the dash, near the steering column — its exact side differs between left- and right-hand-drive cars).
- Press and hold the button until a confirmation signal is heard.
- The TPMS warning light flashes twice to confirm. The procedure is complete.
A short drive lets the system settle and the light goes out.
Light Won’t Go Out? Work Through This
- A tyre is genuinely low: the system is doing its job — find and fix the leak, re-inflate, then reset.
- Reset not stored: hold the button until the confirmation signal and the light flashes twice.
- Flashing (not steady) light: a flashing TPMS light points to a sensor fault — a flat sensor battery is common on older cars. The car may store a code you can look up on autodtcs.com.
Frequently Asked Questions
Where is the TPMS button on a Mazda 3?
Low on the dash near the steering column. Hold it with the ignition on until you hear the confirmation signal and the warning light flashes twice.
Do I have to reset after disconnecting the battery?
Yes — re-initialise the TPMS after any battery disconnection, with the correct pressures set.
Why does the light come back a few days later?
Either a tyre is slowly losing air, or it was a little low when you reset. Re-check all four cold pressures and reset again.
Do I need to reset after just topping up the air?
Yes — any pressure change shifts the reference, so reset after any adjustment.
After tyre or seasonal-wheel work it is worth confirming the service reminder is clear — see our Mazda 3 service indicator reset guide.
