Newbie to FFH - 2 questions

[DR SAW]

1. Will running the heated seats when a bit chilly get me better gas mileage, or running the heat makes little difference? I tried using the option on the cluster for "Accessory" usage, but did;t see it move much with both scenarios.

 

2. After i turn my car off, I see the mileage for that trip, and long term mileage. even though I reset the mileage trip computer, that still pops up - does it reset when I refill the tank or for the duration (10, 20, 60 min) I have the efficiency leafs on?

 

Thx! (car rocks, BTW)

Answering number 2 question only, there are 4 mpg feedbacks. I found the leaves rather useless, and changed them 2 minute MPG bar graphs the first day, using the steering wheel buttons on the left. That's the first mpg feedback. They can be every 1, 2 or 5 minutes per bar. (10 minutes, 20 minutes, or an hour for full width of ten bars). You set that up.

 

The second is the resetable mpg, that displays in the information page, HEV tab, and above the bar graph on the dash. You have to reset it manually with the steering wheel buttons, I reset it at every gas fillup, or at the beginning of a trip. It will not reset itself.

 

The third feedback is the long term mpg. It also will not reset itself, unless the battery is disconnected, or the computer shut down for some reason. You can reset that also with the steering wheel buttons, but it is harder to do, it's deep in the menu, and you definitely want to be stopped with a minute or so on your hands to do it. The long term mpg displays when you turn the engine off, but don't take the key out.

 

And the 4th mpg feedback is when you turn the engine off, and wait a few seconds before taking the key out, you will get a summary of mileage for just the last trip from when the engine was started the last time. If you forget to look at it, (as we often do since we are in a hurry to do something whenever we stop), you can bring it up again by turning the key on, all the way to just before start, then back off one key position. Once you hit start again, you wipe out this 4th feedback.

 

If you just got your car, and you have the 502A package, I bet you didn't notice that on the "i" (information) tab, it gives you the altitude above sea level. On mine it is in rather small type, too hard to see while driving, but as a passenger, I have found it interesting, especially on a trip. I now know which towns around me are higher and lower altitude, and this does impact my mpg going to and from them.

 

I'll take a guess on your first question that your heated seats pull about 8 amps, and hence would have about the same impact as having your bright lights on versus no headlights. I think the impact of daytime sun load increasing your AC requirements in the summer would be a greater impact, since that would bring in a higher compressor load and more ventilation fan. But I am speculating and I wait to be corrected by some other forum members who might have the actual numbers.

Calling for cabin heat will make the ICE run more and decrease mpg more than the heated seats.

Thx. Stupid question: What does ICE stand for so i am better educated?

ICE = Internal combustion engine

HVB = High voltage battery

EV = Electric vehicle (mode)

PSD = Power split device (eCVT)

eCVT = Electronically controlled continuously variable transmission

DC to DC converter = Solid state electonic device that on many hybrids (FFH, Prius) converts HVB voltage to ~ 14 vdc to charge LVB. There is no alternator.

LVB = Low voltage battery

 

There's a lot more.
