I am driving and the gas gauge is showing 3 bars and and then the "low fuel" message is displayed. In my mind 3 bars should be about 1/4 tank of gas remaining. Is the gage not linear ? Since it displays "low fuel" and does not display miles remaining how many miles can I go ? I don't have a good feel if this means running out of gas very soon or not so soon.

On the screen between the instrument cluster you can scroll to a screen that will show the estimated fuel mileage plus the estimated range left on the current amount of fuel.
Yes I have that screen up however it was showing a number of miles remaining and then it replaced that number with "low fuel". Seems like once the number gets to 60 km it changes to "low fuel". Probably because at that level it can't be accurate. I am more concerned about the 3 bars showing at this point. Like I said I don't believe the gauge is linear and looking for someone to comment about this.

With the 7" display, if you look at the divisions on the scale of the gauge, you will see red lines. That's where the fuel warning goes off. It is approximately 1.5 gallons left out of 12. The gauge is pretty linear based on an odb2 scan.
For the smaller dash display, I'm not sure what it is. I'd assume the reserve quantity would be the same.

Keep in mind that moden cars are designed to make it very difficult to actually run out of gas. The Low Fuel warning typically comes on when the range drops below 40 or 50 miles. The fuel level gauges are also generally skewed so that it will hit 'E' early, or analog gauges will go below 'E' before you actually run dry. I've seen cars flash warnings, beep at you, basically convince you that you will be stranded by the side of the road at any moment..then when you make it to the station and fill up you see there was at least a gallon and a half of fuel remaining.
Running dry is generally bad for fuel pumps on fuel-injected engines, so carmakers use these measures to keep it from happening.
My brother still manages to do it though.....

You've seen one that has come even close to correct?

All mine have been pretty close. Less accurate when tank is full obviously but pretty good. The car can never know how you are going to drive it.

My wife's Taurus X is pretty good. The light comes on, and assuming similar topography from a few hours before the light, it claims 80 km's to empty (it estimates from average fuel consumption). I have run the Taurus X 60 km's on the light and had no issue. My TrailHawk claims "Low Range", but just before that happens, I am at 70 Kms range. I have run in "Low Range" for 60 kms, then filled up, about 45 litres (48 actually, I think) and all was good.
Level smooth road, few hills and no significant head wind, I would expect 65 kms from the light coming on. Any of those are off, I would reduce that by 30 to 50%. The Renegade estimates range from average fuel consumption as well. Mine is with a 2.4 petrol engine. Others may vary.

The range estimator in my Volt was extremely accurate, this one... not so much.
Same goes for the navigation, arrival times are way, WAY off.
