Be sure to share your experiences with the car... everyone's input is helpful. Here on the board I have learned what to expect from my car ... and what not to be worried about "because it is normal" for the car to do a particular thing.
For example I have learned that it is normal for the car to get about 5 or so mpg less in the winter than other months. Also that the VENT under the back seat is what keeps the batteries operating at the correct temp. using the cabin air to heat or cool them... thus do not attempt to "save" by not using the AC or Heat... if you want the batteries to be operating in the correct temperature range.
It is good to know also that the Honda Accord Hybrid is designed to function at it's peak when "everything is warmed up" to operating temperature. That takes a little while. You should drive at least 10 miles before expecting it to reach the expected and advertised mpg. If you do a lot of short trips, as I do, you are bound to be disappointed average mpg.
One other thing... I have noticed if I just drive the car like I would any normal gasoline car it seems to perform better than if I try to drive like the "little old man" that I actually am. The car seems to know how to save gas better than I do... it is programed to economize with "normal" driving. At least I haven't been able to "out think it".
