Hello everyone, I have a 2009 Hyundai i30 2ltr hatch. I can't get my fuel to empty to appear by pressing trip button. It just stays on trip and won't change from trip when I press trip button. Any suggestions?

I would start with the simplest and most likely first.
Try pressing and holding the trip button and 'massaging' it with a bit of pressure.

Your suggestion didn't fix the problem with trip button

Assuming it did work in the past so it is a feature in your car, you may need to get in behind the panel closer to the button.
But first, another action worth trying is disconnecting the battery for 30 minutes to reset the logic.
