Blue arrows VS. Yellow arrows?? Whats the difference?

Yellow arrows show that you are using battery power to help move car. Sooner or later that energy has to be replaced. Some of it will come from regeneration when stopping, but some of it has to come from the engine driving a motor/generator.

Green arrows indicate regenerated energy flowing to battery. That is a good thing if you have to slow down anyway, but if you are trying to get maximum coast, that regeneration will slow you down a little.

No arrows show that you are really coasting, almost like old fashion free wheeling. This gets you the most for your pulse and glide action. If you have green arrows and press slightly on the go peddle to make all the arrows go away you will actually feel the car speed up a little because it is rolling more easily.

Since this pulse and glide won't work above about 41mph, I usually let up on the gas when the speedometer gets to 40mph and let the car slow down a couple of miles per hour with green arrows then go back into no arrows glide.

Hope this helps.

 

I love P&G but it slows down too fast to suit me! 40 to like 29 or the like seem to take no time at all. at the end of my day I like to travel at speeds less than that and on battery only knowing it will charge the next day anyway to heat up.

I usually do 50mpg but today I got to 57 playing with my SGII. neat toy!

 

There are actually 3 colors of arrows:

Orange arrows show mechanical energy transferred from the ICE to power the wheels or to turn the generator (MG1).

Yellow arrows show electrical energy transferred to power the car or to charge the battery (often both at the same time)

Green arrows show electrical energy that is from regeneration and would normally be lost as heat when braking or powertrain loss when coasting.

 

Another important thing to note is that 99.9 MPG is the maximum display, so it could be 99.9, 345, 107, 220, infinity, etc. Therefore, when you see the 99.9 MPG with yellow arrows and then again with blue arrows, don't think the car is getting 99.9 MPG. If you get a Scan Gauge, you can read up to 999 MPG.

 

This means you aren't hitting the glide quite right. You are getting regenerative braking.

Change to the energy flow display and practice "no arrows" glides until you can do it without referring to the display. With flat or very slightly downhill I can glide miles, literally, at 99.9 MPG.

 

I found the TCH P&G's much easier than the Prius. The pedal on our Prius was too sensitive, but the 09 TCH seems to be much easier to get it to glide. So far I am up to 38 MPG mixed city highway. If I can get on a very long stretch of open 55MPH road with light traffic I can get it over 42 MPG.
