I have a GLS with the 17.2 gallon tank. Does anyone know how much gas is left in the tank when the low fuel light comes on?

 

I know with the Elantra it's something like 50 miles of driving left, give or take.

 

I'd suggest driving until the light comes on and then fill the tank. Subtract the amount you filled the tank with from the total amount that tank holds (17.2 gal) and you will have your answer. Multiply that number by your average MPG and you will get your range.

My Tib has a 14.5 gallon tank. It usually takes about 12 gallons to fill once the light goes on. That means I have about 2.5 gallons in the tank when the light goes on. With an average MPG of about 24-mph, I have a range of about 60 miles.

From what I've seen, other Hyundais also have thelight go on with about 2.5 gallons left in the tank.

However, letting you tank get that low is not a good idea. You should fill your tank when it gets to about 1/4 left. The fuel keeps the fuel pump cool and running the tank that low regularly will hurt the pump.

 

My 3.3L 2007 Santa FE light comes on with about 50 miles to go (according to trip computer), which is less than 2.5 gallons

 

I've got a 2003 Santa Fe GLS and found that there are between 3 to4 gallonsleft over when the light comes on.
