I got a message that you asked why your 720 dash showed a 200 mile range on a full tank versus the 418 you expected. Maybe you edited your post.
Anyway, the range is dynamic and will adjust based on your most recent Miles per gallon. You have a 15.9 gallon tank and this seems you are getting about 12.5 miles to the gallon. 418 would put it at 26 miles per gallon which isn't likely!
If I drive very conservatively in Comfort mode for powertrain, I have seen at best 17.5 miles per gallon. That is still stop and go driving with the Eco stop/start system enabled. I only have about 540 miles on the car.
