If the tyre-pressure warning has come on in your Alfa Romeo 4C (2014–2018) after you’ve adjusted the pressures or changed a wheel, the 4C uses an indirect system — there’s no sensor in each wheel, so you reset it by storing the new pressures and driving. Here’s how.
How the 4C’s System Works
The indirect TPMS watches wheel-speed data to spot a tyre going soft, so after any pressure change you tell it the new pressures are correct, then let it learn them on the move.
Resetting the System
- Park level and set all four tyres to the correct cold pressures (placard / handbook figure for your wheel size).
- Switch the ignition on and confirm/reset the tyre-pressure setting in the menu where offered.
- Drive for about 20 minutes at over 25 km/h (15 mph) — the new pressures are then stored as the baseline.
If the Warning Stays On
- Recheck every tyre — one below spec keeps the warning on.
- Complete the learn drive — short trips may not be enough.
- The 4C is staggered (wider rears) — make sure each axle is at its correct pressure.
- Still showing with correct pressures? A fault may be stored — look it up on autodtcs.com.
Frequently Asked Questions
How do I reset the tyre pressure light on an Alfa Romeo 4C?
Set the pressures, confirm/reset in the menu, then drive about 20 minutes above 25 km/h to store them.
Does the 4C have pressure sensors in the wheels?
No — it uses an indirect, wheel-speed-based system, so there’s no in-wheel sensor battery to fail.
Why won’t the warning clear?
Usually a tyre still below spec, or the learn drive wasn’t long enough.
Do I need a tool?
No — setting the pressures and driving is all that’s needed.
If the warning came on with other lights, decode the code on autodtcs.com.
