The one on the smaller screen is pointing to the distance to empty estimated miles. It is a static icon. It is a bit confusing considering the other icon near the fuel gage is actually pointing to the fuel filler side of the vehicle.
Funny you mentioned that, first time going to the gas station I pulled to the wrong side because of the top arrow. Good thing it only takes once to get it, but they should of left it out or make it look totally different.
It's funny. I hadn't noticed the arrow that was confusing Jane until this thread. Thank you for bringing it to my attention. Clarification between the two is now part of my delivery/orientation when I sell a new JX. I used this info just yesterday.
