Yep, I got it to work. You just have to clear (or reset might be a better word) the previous trip to start a new record. That will move the current record into a previous trip and start your new record. Reset it every time you want to save history. It's like setting a "trip" odometer, but with the added feature that it saves the history. Works great, but a little non-intuitive.
I still don't get it. What does "clear the previous trip" mean? I reset both trip a and trip b. I've cleared the data on the past history screen and that didnt work either. It didn't move the last data to the left
The manual says:
Displays the average fuel consumption between each reset of the total average fuel consumption on the multi-information display. What the heck???
At my last fill up, I reset both trip odometers. My avg mpg says 51.5 on my multi informational display <g>. The past history is reading about 40 mpg. When I bought the car, this was working correctly. I had at least 2 bars on this display. After I cleared it the first time, only one.
