For the last 2+weeks we have been the proud owners of a new GC Limited with the Hemi. After owning a 2016 Cherokee Trailhawk for the last two years, the move to the GC was a noticeable improvement in many ways and we are very happy with it.

One thing I haven't figured out is the low fuel warning light. At about the 230 mile mark after the last fill up, the little yellow gas pump light in the instrument cluster came on. The gas gage shows the tank is about 3/8 full and the mileage indicator says I am getting 15mpg. By either measure I should have around 9 gallons still in the tank and the owners manual says the warning comes on when you have only 2.4 gallons left in the tank.

I should note that the owners manual shows a gas pump symbol for the low fuel warning but I am seeing the gas pump symbol with an upwards pointing arrow above the symbol and also a downward pointing arrow below the symbol. Can anyone enlighten me as to what is going on. The owners manual doesn't seem to explain this. I haven't read all 614 pages but have tried to find the answer without success.

Thanks.

Are you sure you're looking at the low fuel indicator and not the Fuel Page in the EVIC display? Since you mention the up and down arrows, thats what makes me think that. If you press the up and down arrows on the left of your steering wheel, you should see other pages like tire pressure and whatnot. The low fuel light should be separate.

"but I am seeing the gas pump symbol with an upwards pointing arrow above the symbol and also a downward pointing arrow below the symbol"

Also, just to pass along to maybe save another headache since you're new to the GC, make sure the dimmer for your dash lights is not latched into one of the notches when you roll it all the way up, or else the radio display will never dim at night. Dim them all the way down, and then roll it up gently until it stops, and do not click it into the first position as that locks the dash and radio lights into day (bright) mode.

Hope this helps.

The tank should hold 24 Gallons. An 1/8th of a Tank should be 3 gallons. 2.4 Gallons would be 1/10th of a tank.

When you get the low fuel light, you should fill up right away and see how much fuel was left in the tank. Keep in mind the filler neck can hold up to a gallon of fuel on some vehicles, the filler neck is not included in the tank capacity. But if it takes 15 gallons to fill up, then you know the Gas Gauge is good an the low fuel warning light is bad. If it takes 21.6 gallons you know its the gauge.

Maybe you could take a picture of it. The only "idiot" light would be the fuel pump at the top of the fuel gauge changing from the usual white to yellow, so I'm guessing the warning you are seeing is appearing on the screen?

Here's a clip from my owners manual:
INSTRUMENT CLUSTER INDICATOR LIGHTS
– Low FuelWarning Light
This warning light indicates when the fuel level reaches approximately 1.5 gal
(5.8 L). This light will turn on and a single chime will sound.

Yep, that sounds like exactly what it could be, especially if the EVIC is displaying mpg information.

So what might be confusing him....

At 3/8th of tank, the EVIC automatically switches to the Fuel Page to anticipate the driver planning to make a fuel stop and providing info for that planning.

It doesn't turn Yellow to actually indicate low fuel until the fuel level actually gets down to 1/10th of a tank.

That makes sense at least.....

I don't know if it changed recently, but the manufacturer's never take the time/money to calibrate the fuel gauge, they just stack the tolerances to make sure the gauge never reads higher than actual and you can always count on it reading a little lower than actual. That has resulted in more than a few vehicles that had fuel gauges way off, my 4th Generation Mini-van, as well as having a mechanical AT shifter that was as bad as the Electronic shifter in the '15-'16 vehicles, the fuel gauge read a good 1/4 tank lower than actual fuel level.

The parts diagram shows fuel pumps with two fuel level sensors and floats. Don't know if that is just to show both extreme positions of one float and sensor, or if it uses two sensors in different positions to average fuel level, or if one sensor is the gauge and the other low fuel warning. If the case is the WK2 has a separate sensor for gauge and low fuel warning, then a big difference between the two could be possible, every once in a while someone is going to get a vehicle with the gauge off a noticeable amount.

Thanks guys. With your help I figured out what was going on. The "gas pump" symbol was the result of the fact I was looking at the fuel economy in the Instrument Cluster Display as a couple of you suggested. All is well now and the five gallon can of gas I put in the storage area in case I ran out of gas can be removed. :)

The GC has so much more information available and programmable than the Cherokee it is amazing.

Thanks for the help.

Hello lloydo,

If you decide to get this checked out by the dealership let us know. Although we're not trained technicians, it may be something beyond the surface. We'd be glad to help during the servicing process.

I've never seen that. Is that a setting somewhere?

My 2011 doesn't do it.
I was speculating based off what the O.P. told us.

As he said, our speculation was correct.
But he wasn't clear if the fuel economy page just comes up all on its own when fuel gets down to a certain level, or if he just happened to be switching to it by himself and mistaking the symbol he saw.

Could it be an owner configurable item, done in the EVIC menu?

Mongo, the EVIC in the MY11-MY13 is completely different than the setup in the MY14+. There are substantially more settings and options in the later version and checking them is always a good practice when something, um...strange...seems to happen. :)
