The tyre-pressure warning on your Cupra Formentor (KM, 2020–present) lights up when one or more tyres drift away from the reference the car has stored — typically after you adjust the pressures, rotate the wheels, or the temperature drops. It is a monitoring alert, not a breakdown, and there is nothing to repair. Once the pressures are back where they should be, you store them again as the new baseline. It is entirely a driver-seat job: no jacking, no diagnostic tool, no sensor pairing.
How the System Works on This Model
Most versions of this generation use an indirect system: instead of a sensor inside each wheel, it reads wheel speed from the ABS sensors. A tyre that loses pressure gets slightly smaller in rolling diameter and turns marginally faster, and that mismatch is what raises the warning. Because the alert is a comparison against a stored reference rather than a true pressure reading, you must re-store the pressures whenever you change them on purpose — otherwise the car keeps judging the new pressures against old numbers. Certain performance trims may instead carry in-wheel sensors that show a live value per corner; on those, the store step simply confirms the correct figures.
Before You Begin
- Adjust pressures only on cold tyres — the car standing a few hours, or driven under about two miles.
- Use the figure on the driver’s door-pillar label or fuel-flap, matched to your load and wheel size.
- Set all four corners, plus a full-size spare if fitted.
- Store only after every pressure is right, so you don’t lock in a wrong baseline.
Inflate First
Set all four tyres cold to the door-pillar label figure, then store the reference.
Storing via the Menu
- With pressures set, switch the ignition on.
- Open ‘Vehicle’ / ‘Settings’ on the touchscreen.
- Choose ‘Tyres’ → ‘Store tyre pressures’ (SET) and confirm.
Or via the Button
If a physical TPMS button is fitted, set the pressures, ignition on, then hold the button until it confirms.
If the Light Won’t Clear or Won’t Stay Off
- Check every tyre — the system reacts to a single odd corner, so one that is a few PSI down keeps the warning lit.
- Re-store after any change — inflating, deflating, rotating or fitting a different wheel all move you off the stored baseline.
- Cold nights can drop pressure enough to trip the light by morning; top up and re-store rather than assume a fault.
- A space-saver or mismatched spare rolls at a different rate and can set off an indirect system until the normal wheel is refitted.
- A slow puncture makes the light return within a day or two of storing; get the tyre inspected for a nail or a weeping valve.
- On sensor-equipped cars, a flat sensor battery or a broken sensor holds the light on despite correct pressures — that needs a specialist.
After the Reset
Once you confirm the store, the warning normally clears immediately, or within a short drive as the system re-averages the wheel data. It then stays off for the trip and afterwards, provided the pressures hold. If it clears and reappears a few days later, that is the monitor working correctly — something has changed, so recheck and store again.
Frequently Asked Questions
How do I reset the tyre pressure light on a Cupra Formentor?
Set all four tyres to the correct cold pressures, then go to Vehicle → Settings → Tyres → Store tyre pressures and confirm, or hold the TPMS button if one is fitted. Storing tells the car the current pressures are the new normal, and the warning goes out once it accepts them.
Do I need a tool or a garage visit?
No — the Formentor stores the reference itself from the touchscreen, so there is nothing to plug in and no appointment needed. A tool is only relevant if the car uses in-wheel sensors and one fails or is replaced, which is a separate repair rather than a routine reset.
Why does it keep coming on in cold weather?
Air contracts as it cools, so pressures dip a little on a cold night and can fall below the stored reference by morning. That is normal seasonal behaviour, not a leak. Reinflate to the door-pillar figure while the tyres are cold, then re-store, and the light should settle down.
The light came on straight after a wheel swap — is that normal?
Yes. As soon as you rotate the tyres or fit different wheels, the rolling pattern the system learned no longer matches. Confirm each pressure is correct and run the store step so the new set-up becomes the baseline, and the warning clears once the reference is updated.
How long until the light goes out?
Often the moment you confirm the store, though an indirect system may need a few minutes of driving to average the readings before the light drops. If it is still on after a normal drive with all pressures correct, recheck each corner — a single low tyre is the usual reason it hangs on.
Is it safe to keep driving with the warning showing?
Take it as a cue to check rather than to ignore. A steady light usually means a small deviation, but it can also flag a genuine slow puncture. When it is safe, pull over, look for an obviously soft tyre, and set the pressures at the next opportunity before storing the reference again.
