Low tire pressure indicator lights up even after

You will need the dealer to scan the system for the problem that giving you a false indication of low pressure. Also make sure the spare has the correct pressure.

If you are referring to the TPMS light (warning light), there isn't one. The procedure requires the use of a system (computer) called the GDS (Global Diagnostic System). Only the Hyundai Dealerships have this system (proprietary). If you are referring to a 'Low Tire Pressure" warning light, simply raise the pressure in each tire to the manufacturer's recommended minimum pressure (psi - between 30 & 35 psi). The low tire pressure light will turn off after 5 minutes of driving.

FUEL CONSUMPTION CAN BE MANY THINGS LIKE LOW TIRES PRESSURE.LEAD FOOT ON ACCELERATOR .FUEL LEAKS.QUICK STOPS AND GO.DIRTY AIR FILTER.BRAKES DRAGGING.LOW ENGINE COMPRESSION.AND A BAD OXYGEN SENSOR.

When your tires are cold there is less psi in them. only after you drive does the air in your tires heat up and increase in psi. check your tires for 35 psi before you drive around in car. TPMS-Tire Pressure Monotoring System

I'd like to disable this also. Mine has been on for a few months now for no apparent reason. I hope there is a way to disable this light permanently.

set your tire pressure to manufactuters specs. its a low air warning

low tire

the sensor in the tire may be faulty. If you have taken it and checked the air pressure in the tires already and it stays on then you probably have a faulty sensor. try airing the tire up a little more and see if it goes out. If not you may need to go to the dealer. They should be able to connect to the computer and verify the faulty sensor. Did you air up all the tires? Some systems will only tell you a tire is low and not which tire it is so air them all up too!

air pressure low in 1 or more tire[s] check pressure and add air to low tire light resets

I suspect this is a low tire indicator, mine drove me nuts when I didn't know what it was till a buddy of mine told me. (my tires did not even look low to me). I would be willing to bet that the company that did your oil change was nice enough to put some air in your tires. Doing so, your light went off for a bit, but the slow leak is now getting low again and you will need to get it patched/plugged/repaired or filled with air again to get the indicator to go back out.
