How to reset mpg without re-fueling?
This has been evading me for some time. On the Trip Info screen, there are two displays: "Consumption" showing MPG after re-fueling with a real-time bar graph display (similar to that on instrument cluster) and cruising range; and a "Cruise" display with avg speed and distance traveled. Say I've re-fueled a few days ago, and have 3 days of city driving stored in memory, but now I'm ready to take a highway trip, how does one re-set the old data? Now, the city mpg will be averaged into highway mpg. How does one cancel this out? Sounds like you cannot get a fresh start mpg reading on a highway trip, unless you "fill up" just prior to starting out. 
Is this what Lexus intended?
Having a trip computer which automatically senses "refueling" (e.g. 10 gallons minimum?) is a nice convenience, but does anyone know how to reset the mpg history manually? To me, that would make more sense!

Yes I have the Nav but I think the screen is common to all versions. The reset button on the bottom of the screen is for the distance only. Looking for a reset on the mpg. Thanks for your reply.
