After adjusting pressures or changing a wheel on your Fiat 500X (334, 2015–present), you reset the tyre-pressure monitor so it relearns the correct baseline. It’s done from the dashboard buttons — 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 Dashboard
- With the vehicle stopped, turn the ignition key to the ‘MAR’ (on) position.
- Briefly press the ‘SET’ button, then use the menu button to step through — repeat 2–3 times until ‘RESET’ appears.
- Briefly press ‘SET’, select ‘YES’, and press ‘SET’ again — ‘Confirm’ shows.
- Drive for about 20 minutes at a steady speed 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 a run after the reset.
- 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 500X?
Ignition to MAR, use the SET/menu buttons to reach ‘RESET’, confirm with ‘YES’, then drive ~20 minutes to calibrate.
Is a tool needed?
No — the 500X resets from the dashboard buttons 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 500X battery guide.
