How do i reset the check engine light on Hyundai Santa Fe?

When the check engine light turns on in Your Hyundai Santa Fe You should stop driving as soon as possible. Driving with a check engine light can damage the components in Your vehicle if there is a serious problem. Once You have stopped You can use an OBD II scan tool on the vehicle to read the code that was stored to the ECU. If it is a simple code like a vacuum leak then I recommend removing and reinstalling Your gas cap and resetting the code and driving off. If it is a more complex code then You will need to replace components in Your vehicle to get the light to turn off on the dash.
