After adjusting pressures or changing a wheel on your Fiat 500 (312, 2007–present), you reset the tyre-pressure monitor so it relearns the correct baseline. It’s done from the dashboard MENU button — no tool needed.
Set the Pressures First
Inflate all four tyres cold to the door-pillar / fuel-flap label figures, then reset — the system takes whatever is in the tyres at reset time as ‘correct’.
Resetting via the MENU Button
- Stop the vehicle and turn the ignition key to the ‘MAR’ (on) position.
- Press the MENU button and scroll to ‘Tyre pressure’.
- Press MENU — ‘RESET’ appears; select ‘YES’ and press MENU.
- ‘RESET SAVED’ confirms it.
- Drive for about 20 minutes, exceeding 80 km/h (50 mph) where safe, so the system calibrates.
If the Light Stays On
- Recheck every tyre — one low corner triggers it.
- Complete the drive cycle — the calibration needs the higher-speed run.
- A genuine slow puncture keeps the warning on — inspect before resetting.
Frequently Asked Questions
How do I reset the tyre pressure light on a Fiat 500?
Ignition to MAR, MENU → Tyre pressure → RESET → YES, then drive ~20 minutes above 80 km/h to calibrate.
Is a tool needed?
No — the 500 resets from the MENU button and a drive cycle.
Why did it light up in cold weather?
Cold air lowers pressure; top up to the label figure and reset.
It lit after a wheel change — normal?
Yes — reset and drive the calibration cycle so the new wheel becomes the reference.
Got a TPMS fault code rather than a low-pressure warning? Look it up on autodtcs.com. Changing the battery too? See our 500 battery guide.
