Welcome to the community, @ciquta !
My DS7 is a few years older, but I click on the outside button of the wiper stick to toggle views.
Have you tried that?
AVG is listed as Trip 1 or Trip 2. You just need to reset it occasionally. However, if you’re looking for instantaneous fuel consumption, there’s no such option.
The photos show the data from the last trip. From the left: engine shutdown time (Start & Stop), mileage with the current fuel level, average speed for that trip.
