I'm a new Leaf owner and I tried an experiment today. I wanted to see what turtle mode was all about. My round trip to work is 141 km. I have yet to try a full trip without plugging in at work. Most of my trip is highway and up and down hills, sea level to 300 meters. I have been using the cruise control at a steady 80 km/h. Well I made it home safely. At 7 km on the guess o meter it switched to three flashing bars and the warnings about looking for a charge station came up. I parked the car, I didn't plug it in. Later in the day I took the car out for a short trip. I wanted to see the turtle. About one kilometre from my house the turtle came out. I was at my destination. This is where I made my mistake, instead of driving it home, I parked my Leaf. When I went to move my Leaf again it would not go back into Drive. It would shift into "N" so I had to push the Leaf over to a 110 volt outlet. 1 1/2 hours later it had enough charge so I could drive home. While I was waiting I read all about this in the owners manual. Note: You don't have to wait till the guess o meter has a number in it before you can move. The manual says you do but I still had the three flashing bars. Good experiment I learned a lot and I did it safely near my home not out on the highway. According to the Range Chart I should be getting 7.4 km/kwh I was able to get 7.1 km/kwh. Pretty good for a start.
