When the tyre-pressure warning light comes on in your Honda Jazz Mk3 (GK, 2015–2020), it usually just means the system — Honda calls it the Deflation Warning System — needs to relearn your current pressures after a check, top-up or wheel change. You reset it from the dashboard menu (or, on cars with a TPMS button, by holding the button). This guide shows both.
How the Jazz System Works
The Mk3 Jazz uses an indirect system (the Deflation Warning System) that watches the ABS wheel-speed signals rather than a sensor in each wheel. Because it works from a stored baseline, you must re-initialise it whenever you change the pressures — there is nothing to read, only a reference to store.
Set Your Pressures First
The reset stores whatever pressures are in the tyres at that moment, so they must be correct first. Set all four (cold) to the figures on the placard on the driver’s door pillar, using the laden column for a full load. Never reset with a tyre already low.
Cars Without a TPMS Button — Reset From the Menu
- Make sure all four tyres are at the correct cold pressure.
- Put the gearbox in N or P and turn the ignition on (do not start the engine).
- Press and hold the “INFO” button until the service display appears in the menu.
- Press “INFO” to scroll, and select “CUSTOMIZE SETTINGS”.
- Press “SEL/RESET”, then select “DEFLATION WARNING SYSTEM”.
- Wait until “COMPLETED” appears on the display. The new pressures are stored.
Cars With a TPMS Button
- Set all four cold pressures correctly and turn the ignition on.
- Press and hold the TPMS button for 3 seconds — the warning light flashes twice to confirm.
- Drive for about 20 minutes, keeping your speed above 35 km/h (22 mph), to store the new pressures.
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 re-initialise.
- Initialise not completed: repeat the menu steps and wait for “COMPLETED”, or hold the button until the light flashes twice.
- Big front-to-rear split: set them to the placard figures; indirect systems dislike large mismatches.
- Light stays on with correct pressures: a persistent fault may be stored — you can look up what a code means on autodtcs.com.
Frequently Asked Questions
Does the Jazz Mk3 have a sensor in each wheel?
No — it uses the indirect Deflation Warning System based on the ABS wheel-speed sensors, so there is nothing inside the wheel. The reset is done from the menu or TPMS button.
Where do I find the reset in the menu?
Hold INFO until the service display shows, press INFO to scroll, select CUSTOMIZE SETTINGS, press SEL/RESET, then DEFLATION WARNING SYSTEM, and wait for COMPLETED.
Why does the light return after a few days?
Either a tyre is slowly losing air, or you initialised while a tyre was already low. Re-check all four cold pressures and re-initialise.
Do I need to reset after just topping up the air?
Yes — any pressure change shifts the baseline an indirect system relies on, so re-initialise after any adjustment.
After tyre or seasonal-wheel work it is worth confirming the service reminder is clear — see our Honda Jazz service indicator reset guide.
