The Blue Wedge Posted March 26, 2021 Report Share Posted March 26, 2021 Greetings, I am wondering what this towing mode does, it's on my 14 SEL, 3.5 AWD. For the life of me, I can't find anything in the owners manual about it, but when you toggle through the settings, there is normal, and DTE mode, I don't tow with this vehicle at all, ( have Expedition for that) and I have driven with it in this DTE mode, but can't tell any difference with how it shifts, or drives, what am I missing here?

Haz Posted March 26, 2021 Report Share Posted March 26, 2021 (edited) The "Normal or Towing" selection relates only to the calculation of the Distance To Empty value displayed by the trip computer. The Edge/MKX owners guide and the workshop manual both lack a definitive explanation, but according to one theory mentioned on a Ford truck discussion site, selecting "Normal" bases the Distance To Empty (DTE) calculation upon a 500 mile fuel usage pattern, versus "Towing" which calculates using a 60 mile fuel usage pattern. It seems to reason that resetting the trip computer when beginning to tow would produce a more valid DTE calculation based upon real-time performance, instead of the theoretical "Normal or Towing" historical fuel usage algorithm. Still, as someone said on the Ford truck discussion site, the DTE value is just a guide, and the driver still needs to stop and get fuel when the fuel gauge shows close to empty. Good luck!

Waldo Posted March 26, 2021 Report Share Posted March 26, 2021 Yep, that's all it does, it just adjusts the DTE calculation to better predict when you will need to fill up. Quote Link to comment Share on other sites More sharing options...
omar302 Posted March 26, 2021 Report Share Posted March 26, 2021 From the attached Super Duty quick guide, the Towing DTE uses the average mileage from the last 60 miles, while the normal mode uses the average mileage from a longer distance. Just as @Haz stated above. 2017-Super_Duty-QRG-Version-2_QG_EN-US_08_2016.pdf Quote Link to comment Share on other sites More sharing options...
Haz Posted March 28, 2021 Report Share Posted March 28, 2021 (edited) While researching this topic, I did find mention on the Ford Owner site that the Low Fuel warning triggers at 1/16th of the tank, such that a vehicle with a higher MPG performance history might warn showing 80 miles DTE, versus the same vehicle with a lower MPG performance history might warn Low Fuel showing 35 miles DTE. This explained a difference I noticed between my 2012 MKX that always warned Low Fuel at 50 miles DTE, versus the first time my new-to-me 2015 MKX warned me -- at 73 miles, which I thought was peculiar. Strangely, I think I prefer a fixed interval of warning, which I now wonder might be attainable on my 2015 by using Forscan for Windows to modify an As Built data point. Good luck!

The Blue Wedge Posted March 28, 2021 Author Report Share Posted March 28, 2021 Thanks, guy's for that definition! I never thought it had anything to do with "distance to empty". Quote Link to comment Share on other sites More sharing options...
