Long-time lurker, once in a blue moon poster, who nonetheless appreciates the hard work you put in on this group. :)
I wanted to ask a few questions about the various behaviors of the 07 Sonata (SE V-6, if it matters) when it is running low on fuel. I've seen a few things in the hmaservice.com shop manuals, but I'm still not clear on a few others.
-- The low fuel warning light, lower right corner of the dash, should come on at 9 L (~2.4 gals) of fuel remaining, correct?
-- I've noticed how the range calculation in the trip computer (immediately above the odometer) goes to all dashes and blinks once it estimates less than 30 miles of range remaining. Once, I ran the car 20 miles past the point where the blinking dashes started, so theoretically I should have had 10 miles of range left, or roughly a half gallon.
However, only 16.3 gallons of fuel then went into what is claimed to be a 17.7 gallon tank. Does the Sonata do something like, e.g., my friend's Honda motorcycle, and tell you 'you're empty and you'd better fill up NOW' when you really still have about a gallon in the tank?
-- How accurate would it be, in your estimation, to watch for the start of the dashes, then add 30 to the odometer and figure that's the stalling-out point? Or, to ask it another way, have you seen Sonatas go significantly more or less than 30 miles on the dashes?
-- If I felt crazy enough to experiment with it, by carrying a gas can in my trunk, intentionally running it out to figure out where the run-out point is, and using the can's contents just to get to the nearest gas station, I shouldn't cause any permanent damage to anything, right?
