Trip Histories

reset trip a or b, and follow them until you're ready to reset again.

i use a for tank and b for trips

 

As far as I know, the car doesn't keep records of previous trips. Just trip A & B as @bisco said.

 

Page 197 of the 2010 (North American) Owner's Manual, might be what you're looking for:



I'm not a fan, since the displayed mpg display is a compulsive liar lol, around 7.5% on average. But I think I used that screen once when I'd accidentally reset the trip meter or something.

Now I just use the odometer, much more bullet-proof. Kind of like "running dimensions", a steel detailing term.

 

i was wondering about that, but driving mostly ev, i never paid attention

 

The display only saves monthly miles driven and/or cost. I've yet adjusted the date/time on the MDF because I pull the 12v neg. connection more than I want to. But you'll have to just take photos of trip summary when you turn the car off each trip then calculate them all together after the work week.

Below was my fuel consumption for the work week that just passed.





Filled up tank to 1st click & drove 609 miles this week. I filled up tank to 1st click this Saturday morning, took 9.888 gallons to get back to full tank.

609mi / 9.888gal = 61.589 MPG

MDF does show 64.3MPG, deviation is typically +2 to +3 of actual MPG.
