@jws I've mostly leave the EV / Eco / Power buttons alone.
I'm still trying to figure it out when it runs the engine versus just the battery at low speeds when the battery indicator or throttle doesn't make it obvious. Either way, I appreciate that the engine isn't running all the time on the rare occasions I am stuck in stop-and-stop traffic.
It seems the car gets better gas mileage than I was expecting on longer trips, not as good a gas mileage on shorter trips. May have something to do with the fact my local area is hilly and the engine has to run more.
I wish the entertainment system supported CarPlay. The iPhone integrates well enough with Entune, but I find it annoying that it regularly will play the alphabetically first item in my music collection…
