Just quick questions:

when the fuel warning light comes on, how many litres are left in the tank?
and how many kms should i get out of that?

jsinton is an unknown quantity at this point
Hard to say exactly. It varies. You'll have to find out the hard way if you really want to know. Carry around a can of gas and run it dry.

Guess ill just have to find out later.
Ill just wait til it lights up again and refuel full to calculate remaining litres of the 53L full tank.
Then jst calc avg fuel consumption for max kms at warning.
Thanks anyway.

Donít run it dry. Modern fuel pumps are cooled by the gas in the tank. You could damage the pump.

Last time I saw the light (and kept driving about 15 km), I was able to fill with 48 Liters of gas. I think the full tank capacity is 53L...

Sorry forgot to update the answers i found for this question/thread...

I figured out after refuelling that Low Fuel Warning Light comes on at 10L remaining (same as specified in my previous car's user manual, but not in elantra's)

Spec sheet says combined fuel consumption is 7.8L per 100kms, so based on that, the max distance you can travel when the light first comes on is 120.2kms, and then ur car will fail

Oh, and the other day my fuel meter was pointing to empty for a while but i still had 7-8L left in the tank. So u shouldnt run out of fuel if u go by the fuel meter.

Guessing cars from other countries that dont use Litres and Kilometres as measurements will have different low fuel levels.

Thanks for the replies.

never, ever run a vehicle dry if it has a catalytic converter. the air flowing under the vehicle cools the cat converter
if you are at highway speeds and run out of fuel it can start a fire. no kidding. i was a firefighter for many, many years....

i did this in my 2005 hyundai. when the fuel light goes on, make note of the odometer. drive to the nearest fual station. fuel up.

example:

11.9 gallon tank (accent) fuel light comes on at 350 miles and it was 5 miles before you got to fuel station

took 10.3 gallons to fill it up. mpg = 350/10.3 or 33.98 mpg

at 33.98 mpg you use 0.147 gallons to drive 5 miles

add the 0.147 miles to what it took to fill it up (0.147 + 10.3) and you get 10.417 gallons

11.9 (tank capacity) minus 10.417 gallons and you had 1.483 gallons left when the light came on

at 33.98 mpg using the 1.483 gallons is 50.39 miles if you kept driving until it was out of gas.

it's just math. convuluted, sure, but still just math.
