Evic dte?
 
My wife has a phobia of filling gas. Thus, I always fill the Jeep on the weekends. Last Friday came around, and she did more driving than typical. The light came on, and she called. I told her to watch "DTE" -- as we always have the Fuel Economy screen displayed. I told her if it got really low, she had to fill. She was at work -- 13 mi away from home, and DTE stated 30. OK -- no problem. That's the last she remembered. After she got home safely, she said "DTE" didn't have a reading when she looked last. I said, "impossible -- you must have went to another screen". When I started it Sunday -- sure enough -- DTE said nothing -- no reading -- blank. I said, "we have to get to nearest station NOW, and you are walking if we run out". How did it go from "30" -- to "blank" in 13 miles of driving? Shouldn't it say "0" if you have NO MILES left? Since I wasn't driving, I can't say when it actually went blank (I would know -- because I would have watched it -- she just gets in and drives). We drove 1 mile to the nearest station, and put 23.1 gallons in at pump shut off-- I never top off. Had I known it was that low, I would have added mower gas before driving to station. Argg! Have you ever watched DTE until it gets really low? I typically never run that low.

Check your manual...

From the Owners Manual:

"Distance To Empty (DTE)
Shows the estimated distance that can be traveled with the fuel remaining in the tank. This estimated distance is determined by a weighted average of the instantaneous and average fuel economy, according to the current fuel tank level. DTE cannot be reset through the SELECT button.
NOTE: Significant changes in driving style or vehicle loading will greatly affect the actual drivable distance of the vehicle, regardless of the DTE displayed value.
When the DTE value is less than 30 miles (48 km) estimated driving distance, the DTE display will change to a “LOW FUEL” message. This display will continue until the vehicle runs out of fuel. Adding a significant amount of fuel to the vehicle will turn off the “LOW FUEL” message and a new DTE value will display."

Ahhh -- thanks. Sorry. Manuals are in the basement. We saw the "LOW FUEL" message. That's stupid. Every other car I've owned (mostly FoMoCo) will keep counting down. On purpose, I drove my Lincoln down to "6 miles to empty once" -- just to see how accurate it was. It was accurate. I know "DTE" will vary greatly on your driving style. I told her to drive like a grandma. It won't happen again. I made her fill gas this weekend -- with me watching.

Yea it is a little wierd but on a related note which you may or may not be aware of is that our fuel pumps use the gas in the tank to keep itself cool...run the tank real low and ther isn't any gas to cool the pump. Not that I've heard of early failures but it's just another reason to fill up once I go below half a tank...that and the $90 it takes to fill haha.

Yeah -- I know about the potential fuel pump issue. I typically never run below 1/4 tank -- which is still quite a bit on our tanks.

Stupid question but on a new Grand Cherokee where on the EVIC does it tell distance to empty?

Center of gauge cluster is a fuel economy screen.

I've had some pretty odd estimates from the DTE system as well. I did a highway trip last week on the lower half of the tank, when I left it showed 192 mile range, after 30 miles it still showed 180 or so miles but the analog gauge had dropped to 1/4. Then within the next 20 miles the DTE went from 180, to 90, to 50, to the infamous "low fuel" message. I'm going to do a few most experiments with this; but I sure won't be trusting that magic number when it comes to fueling up.
