Brings up some points. Tires should be rotated based on mileage. Engine service should be based on tachometer hours. We have the technology, just not using it.
I think you are good. My theory below: First Screen MPG is for the miles since you last hit the reset button on the big screen about 19 hours ago. Odometer shows total miles driven but is not linked to the MPG on that screen. Second Screen MPG is what you would expect. Math Works. Third Screen MPG is your Life Time Average (because that is how you are using it) except that the first digit of your life time hours does not appear -- you are missing a leading "1". But the math works with the 1 added. If you don't hit "clear" on the big 7.5" screen like I did, then the OD and lifetime average appear together (I Think). Your EV percentages are remarkable -- I am around 35%.
The maint guide has 10,000 miles intervals but 5,000 under certain conditions like towing, short trips or extensive idling. There is also a note that the oil should be changed at 5,000 if 0W-20 was not used at the last change.
FYI, first change, I'd do it between 2-5k miles and include the transaxle oil at the same time. That will get residual manufacturing debris out and about 2/3d of what is in the transaxle. Then switch to 10k changes and on the 3d change, do another transaxle oil change to dilute the remaining debris to less than 10%. Then have a happy. The reason for the slightly longer, second transaxle oil change is to pickup any sealant beads that falloff in the first 20k miles as well as the well grounded earlier debris. The biggie is getting that first change to drain out the early debris. Bob Wilson
For a G3, it's 10K miles. I have perform the oil service twice doing it myself, and the drained oil still looked ok. Oil changes are cheap if you do it yourself
What is that tiny icon on the bottom-right of the display? A green circle with an arrow? I saw that one time in my Prius... but only once.
I thought in Canada you had a system where the loser automatically must pay the court costs of the winner. In most of the US if you had a $5,000 bill you were fighting over you would take Toyota and/or the dealer to small claims court, cost in Colorado is $85.
