Hyundai uses direct TPMS on UK models — auto-relearn after driving, no button required on most. Newer cars show pressure per wheel in the digital cluster.
Why the Hyundai tyre pressure light is on
Same system as Kia (shared Hyundai-Kia parts). The light comes on for genuine low pressure, dead sensor batteries (5–8 year lifespan), or after wheel changes where the new wheels have different sensor IDs registered.
Hyundai tyre pressure light reset — step by step
- Inflate all four tyres cold to the placard pressures (door pillar).
- There's no reset button on most Hyundais — drive at over 15mph for 10–20 minutes and the light clears itself.
- On i30, i20, Tucson, Kona, Santa Fe, Ioniq 5/6 with the touchscreen: Settings → Vehicle → Tyre Pressure → you can see each wheel's pressure live, which makes diagnosis easy.
- If you've changed wheels (winter swap, new alloys), a Hyundai-specific scan tool or aftermarket TPMS programmer is required to register the new sensor IDs to the car.

If the light won't go off
If the live pressure display shows '--' or '0' for one wheel, that sensor is dead. If all four are showing real pressures but the light is still on, one of them is below the warning threshold — re-check it with a separate gauge.
What it costs
DIY reset free. Sensors £40–£70 fitted at an indie, £85–£140 at a dealer. Replacement sensors must be programmed to the car ID.
Bob's workshop tip
Hyundai's digital cluster makes TPMS diagnosis the easiest of any make — if you can see each wheel's pressure in real time, you don't need a scan tool to find the problem.

What Bob keeps in the boot
A pump puts air back in, but it will not seal the hole. For a nail or a screw in the tread, the repair itself is the Emergency Puncture Repair Kit — £9.99 with free UK delivery: rubber rope plugs, reamer, T-handle tool and rubber solution, posted from the workshop in Birnam, Dunkeld. If you would rather not take a wheel off at the roadside, the quick-fix tyre repair spray is the no-tools option. Keeping the pressures right in the first place is covered in tyre pressures by registration and resetting the tyre pressure warning light, and the pump itself in Bob's electric tyre pump picks.
Be straight about what a plug is: a get-you-home repair for small punctures in the central three-quarters of the tread. Never plug sidewall or shoulder damage, drive gently afterwards, and have the tyre inspected or replaced by a tyre specialist as soon as you can.
