If the tyre-pressure warning has come on in your Maserati Quattroporte (M156, 2013–2024) after you’ve adjusted the pressures or changed a wheel, the system relearns by driving — there’s no button to press. It’s normal for the lamp to stay lit until the car has read the corrected pressures over a decent run; it isn’t a fault in itself. Set all four tyres accurately first and a steady drive clears it.
How the System Works on This Model
The Quattroporte keeps an eye on the pressure at each wheel and compares it with a stored reference. When a tyre falls too low, or when you deliberately alter the pressures, the warning lights and holds until the system has confirmed the new values on the move. Because the relearn is done through driving rather than a dashboard button, the car will accept whatever pressures it reads — so accuracy at the pump matters, especially given the wide staggered tyres this car often runs, where front and rear figures differ.
Getting Ready
- Check the tyres cold, before driving or after only a short distance, so heat doesn’t inflate the readings.
- Use the placard figures on the driver’s door shut, and note the fronts and rears may differ on staggered fitments.
- Set all four corners exactly — on a performance car small errors show up quickly.
- Use a quality gauge; cheap airline heads often read a psi or two out.
- Refit the valve caps so nothing weeps back out during the learn drive.
Completing the Procedure
- Park level and set all four tyres to the correct cold pressures.
- No manual reset is required after a pressure adjustment.
- Drive the vehicle for about 20 minutes at over 25 km/h (15 mph).
- The warning light goes out once the system has read the corrected pressures.
If the Warning Stays On
- Recheck every tyre — one corner still below spec keeps the lamp lit even when the others are right.
- Complete the learn drive — a short hop may not be enough; give it a continuous 20-minute run.
- Mind staggered sizes — make sure the fronts and rears are each at their own correct figure, not a single shared value.
- Cold morning? Pressure falls roughly 1 psi per 5 °C drop, which can trip the warning overnight; top up to the cold figure.
- Watch for a slow puncture — a tyre that keeps losing air should be inspected rather than reset again and again.
- Correct pressures but still lit? A sensor may have a flat battery or fault — look up any stored code on autodtcs.com.
What Happens Next
Once the corrected pressures have been read over the drive, the warning goes out and stays off for the journey and beyond. A brief return in very cold weather that clears as the tyres warm is normal thermal behaviour. A light that comes back on every time you drive, however, usually means one tyre is genuinely low or a sensor is failing, and is worth investigating rather than resetting repeatedly.
Frequently Asked Questions
How do I reset the tyre pressure light on a Maserati Quattroporte?
Set all four pressures correctly to the cold placard figures, then drive for about 20 minutes above 25 km/h — no button press is needed. The steady drive is what lets the system read and confirm the corrected values, after which the lamp goes out on its own.
Is there a reset button?
No — the system relearns automatically as you drive. There’s no need to hunt through a dash menu after topping up the pressures; inflate every tyre to spec and let the learn drive do the work.
Do I need a tool?
Not for a normal relearn. Adjusting pressures or swapping wheels needs only a gauge and the drive described above. A dedicated tool is only required when new pressure sensors are fitted and have to be paired to the car.
How long is the learn drive?
About 20 minutes at over 25 km/h. If the warning hasn’t cleared by then, don’t just keep driving — recheck all four pressures cold, since a single tyre a little low will keep the lamp on regardless of how far you go.
Why did the light come on in cold weather?
Air contracts as it cools, so pressures drop after a cold night and a tyre set correctly in mild weather can read low enough to trip the warning. Top the tyres back up to the cold placard figure and complete the learn drive, and the light should clear.
Is it safe to keep driving with the light on?
Treat it as a prompt to check the tyres soon rather than an emergency, but don’t ignore it. On a heavy, powerful saloon a low tyre affects grip, braking and even handling balance, so check all four at the next safe opportunity and reset once they’re correct.
If the warning came on together with other lights, decode the code on autodtcs.com.
