No I don't have an '18. I have test driven the '18 Leaf once in December 2017. We had up to 1 hour with the car.
You'll note a 99% state of charge value there in the pic. Without Leaf Spy, you should pay attention to that, for now. Forget the GOM (150 miles in that pic).
Not sure what you mean by "The lights of which you speak do not exist". If you're talking about gids, of course they're not displayed on the dash of any Leaf. You need Leaf Spy. Please see https://www.youtube.com/watch?v=cgE8lmySdMI
LBW and VLBW are not specific lights. They're the first warning then second warning, audible via nav system if you have it, otherwise you might just hear a beep. At the 1st warning, a yellow icon should come up on the dash, as well.
If the is talking to too slow or repetitive, use the gear icon on PCs or Macs to increase the playback speed.
In the video at https://www.edmunds.com/nissan/leaf/201 ... r-end.html
, they drove an '11 Leaf until dead. At
- about 1:15 they hit LBW
- at about 1:33: VLBW
- at about 1:56, turtle (The colors seem off on some of the video.)
- at 2:19, they're past turtle and speed is dropping.
('11 and '12 Leafs did NOT have a % state of charge display. That didn't appear on Leafs until model year '13. Also, Leaf Spy didn't exist back. Not sure if folks had figured out battery gids that early on (May 2011).)
For pre-18 Leafs, the warning levels for LBW, VLBW, and turtle were never based upon any specific # of miles or km of estimated (guessed) range remaining. LBW and VLBW sounded at specific gid levels. See earlier posts.
