Thanks - as others as well as you have said that "RHS Passenger Airbag On" stays illuminated it looks like it is by design and not a fault. Hyundai need to update their Tucson NX4 manual, but at least I now know that I don't need to trouble my local dealership.

Thanks for letting me know about your Passenger Airbag ON light. Looks like Hyundai have change the behaviour, but not changed the manual (section 3-52). All seat belt lights are off, and the passenger seat is unoccupied.

230 HEV NX4 Tucson: My passenger airbag ON light (overhead cluster) stays on - manual says it should go off after around 4 seconds. It will swap to indicate OFF and ON when the passenger airbag switch is operated. No other warnings on dash cluster. Can other owners of the 230 HEV NX4 let me know whe...

I have 230 HEV. Yes, it does have the 12v battery reset button on the dash. No separate 12v battery in the boot. It has a 12v tap from the lithium battery pack.
