If the tyre-pressure light is on in your Hyundai Tucson Mk4 (NX4, 2020–present) after adjusting pressures or swapping wheels, it usually just needs the car driven so the system relearns. The Tucson uses an indirect TPMS that works from the ABS wheel-speed sensors, so there are no valve sensors to match and the reset is automatic. Here’s how.
How the Tucson’s TPMS Works
Rather than a pressure sensor in each wheel, the Tucson compares how fast the wheels turn. A softer tyre is fractionally smaller and spins slightly faster, and the system flags it. Because it’s comparing wheels, you set the pressures correctly and then let it relearn by driving.
How to Reset the Tucson Mk4 TPMS
- Set all four tyres to the correct pressure cold — the figures are on the label in the driver’s door opening.
- If your cluster has a TPMS ‘Set’ option in the User Setting menu, select it to register the current pressures (not all trims have this).
- Drive normally for around 20–30 minutes, keeping above roughly 25 km/h (15 mph). The system relearns and the warning clears.
If the Warning Stays On
- Re-check every tyre, including the spare if it’s a monitored full-size wheel.
- One tyre noticeably low — look for a slow puncture; the system is doing its job.
- It flashes then stays on — a flashing TPMS light points to a system fault rather than low pressure; have it scanned.
Frequently Asked Questions
Do I need a tool to reset the Tucson TPMS?
No — it’s an indirect system. Set the pressures and drive; no relearn tool is needed.
How long until the light goes out?
Usually within 20–30 minutes of steady driving after correcting the pressures.
Why did the light come on in cold weather?
Pressure drops as temperature falls. Top the tyres back to the door-label figure and drive.
The light keeps flashing — is that a fault?
A brief check at start-up is normal; a light that keeps flashing indicates a TPMS fault — have it diagnosed.
If a fault code is stored, look it up on autodtcs.com. To clear a service reminder, see our Tucson Mk4 service reset guide.
