Question about Nav and MPG!

I would go by what the owners manual states. With todays
vehicles and superior oil formulations a 2,000 mile first
oil change is not needed.

On our 2010 Prius the first oil change was at 5,000 miles and
than 10,000 for each other. Remember this is synthetic
motor oil, 0 w 20, far superior to oil even as little as 10
years ago.

 

I, too, would like to know how to deactivate the Nav system before you reach your destination. Was hoping there was a voice command, but couldn't find one.

As for getting your average MPG, hit the TRIP button on the steering wheel and watch what happens in the upper dash display. Each time you hit it, it will change the display from Trip A to Trip B to Trip ODO ( or maybe it's just ODO). When it says ODO, that's your total miles driven and total average miles per gallon since the car was new.

If you want to get average MPG for a specific trip, reset either Trip A or Trip B by holding down the button to zero it out.


CORRECTION: Since I was concentrating on MPG measurements for this trip and that tip, I had only briefly looked at the ODO section, and since it kept accumulated miles I figured it kept accumulated MPG as well, but it doesn't. MPG measurement there appears to be the average for your current trip. ie: from the last time you started the car until the next time you shut it off.

 

Try this:

- On your NAV screen hit "Dest" > "Route Options" > "Stop Guidance"

I also think that you can get there from NAV screen "Options" > "Stop Guidance". Going from memory on this one!

Good Luck!

 

The mpg that shows when you are on ODO is actually just the average since your started the car (that's why it's always changing). The only way to get the average over the lifetime of the car is to leave either Trip A or Trip B alone, and never reset it. Seems like a tiny missing piece of functionality (I don't look forward to the day I accidentally reset my lifetime Trip), but it works.

 

These meters are going to get reset sometime, either by a fumblefingered driver or by a clueless service technician during an oil change. So write down the figures occasionally, especially when going in for service, and expect to compute an approximate lifetime MPG from the recorded figures.

 

Honestly you'll get a more precise answer by simply doing the math when you fill up at the pump. Start keeping track of your ODO readings and how much fuel the car takes when you fill it up and make the calculations. I use a Numbers spreadsheet on my iPhone with the simple formulas in it and it always winds up being slightly different than what the C's display says.

Or alternatively you could use Fuelly.com and enter your fillups there. You get a nifty sig picture to use as well

 

if the new systems are anything like the genII... there is/was "resume guidance", " suspend guidance" " delete all destinations" (requires a separate response for yes or no)

the genII has 430 commands or so... i assume the newer ones have more.. i know the number went up a bit for the genIII....

(i used to carry around a list of voice command... along with an instruction manual for installing EV for any other owners i come across)

Here is a link to the genII commands (list created here on priuschat)

here's a link to an outside source that created a list for the genIII

this way you can see how the list is growing. (i forgot a few that i'm going to re test out)

btw... i believe there is a HELP command which gives you a short overview of the what you can do with voice commands.
