When in doubt...read the manual
 
Here's what the manual says:
 
The autostop will function if all of the following conditions are met:
 
1) The vehicle speed is over 8 MPH before the vehicle comes to a stop.
2) The coolant is nearly up to operating temp.
3) The shift lever is in D, D3 or N.
4) You ARE pressing on the brake.
5) You are NOT pressing on the accelerator.
6) The IMA battery has sufficient charge.
7) Climate control is set to lower fans speeds either in manual or auto.
8) Outside temp is between 10 - 100 degress F.
9) The front window defrost is off.
 
My experience is that it works most of the time as expected. Occasionally it fails to stop after creeping forward a few times in a drive-through but never in traffic probably due to much lower "creep" speeds in a drive-through.

yup, shoulda read the manual!
 
it was the front defroster that was "getting" me this time.
 
what's funny is I knew about the other 8 conditions.
 
thanks for checking for me.

Hey that's awesome! I almost mentioned.. "how about the last item" but thought it might sound insulting. I wouldn't be a bit surprised if that greatly affect your poor mileage issue. For city driving the auto stop has a BIG impact.
 
Let us know how it goes!
 
Cheers!

I keep hearing about "driving style" but can't figure out what i'm supposed to do different (than just moving with traffic).
 
I've got about 1300miles and have yet to have a tank get better than 22mpg (via the odometer reading).
 
what am i doing wrong?
 
in city driving,

I do not get it! I have a 2005 EX V6 Auto w/o Hybrid and average 25 miles to the gallon - 27 to 28 Highway (Garden State Parkway with some stop and go traffic) and 20 to 22 in the City. With all the claims, the mileage does not add up! Since I bought my car for 24,000 even versus the local going rate of 28500 for the Hybrid, I do not see a payback!
 
Is it possible that for other than one person claiming excellent mileage, that the Hybrid systems are just not working and the mileage is the result of running a normal V6?
 
Handa seems to have some explaining to do to the vast majority of Hybrid Accord Owners!!!

Many reasons by larsb

There are Accord Hybrid owners getting 36-41 MPG highway. It's not a problem with the technology. If it was, there would be ZERO drivers achieving EPA numbers, and that is not the case. The average for drivers at a certain Hybrid website is 27 MPG for the Accord Hybrids registered there, only slightly below the EPA City number of 29 MPG.
 
There are many reasons for cars not achieving max MPG in the colder months...
 
Car engines must warm up to a certain operating temp before they most efficiently use the fuel. Winter months and colder temps make that transition from cold start to most efficient take a little longer.
 
In addition: Colder tires are harder, so they provide more rolling resistance than when they are warm and soft.
 
Also: new cars (and all the Accord Hybrids are "new" as of three months ago) have what is called a "break-in period" where the metal engine parts are still grinding against each other more rigidly, creating more friction, which also reduces efficiency. OVer time, the "extra metal" shaves off and gets lubricated better (expecially if you use Synthetic Oil) and the friction is reduced, which affect MPG numbers.
 
Also: Honda Hybrids use the "electric assist" much less before warmed up, and since the electric assist is key in MPG gains, the car must warm up before the use of the assist starts becoming most effective.
 
Also: Winter formula fuels used in most states hold less energy and this also hurts MPG.
 
Also: Generally speaking, colder weather in many areas means "rain, snow, or slush or ice" on the roads - these things add additional resistance which the tires must push out of the way to contact the road, so they hurt MPG in that way.
 
Also: Tire pressures also are lowered by the cold. Most people fail to properly inflate their tires all year, but ESPECIALLY in the winter when it is cold and you might have dirty tires and you just dont want to deal with spending time in the cold airing up a dirty tire. Low tire inflation can cause blowouts and adds quite a bit of rolling resistance.
 
Also: Additional idling uses fuel, and many people in cold climes are used to warming their car up in the morning. That is good practice to stay warm, but BAD for MPG numbers. While idling, your car is getting 0 miles to the gallon !!
 
Also: People who use the defroster in a Hybrid are many times using the A/C compressor to help reduce the humidity in the car and clear the fog. That is a MPG killer too.

The average of 27 mpg combined is 16% below the EPA 32 mpg combined. There are so many excuses for why the HAH gets such poor mileage. Why not admit it is a failure as a hybrid. Plus the sales bear that out. You will be seeing them below invoice in many parts of the country, if they are not already there. Honda will be lucky to sell half of their projected 20k units.
 
The truth is the poster getting 22 mpg is probably closer to the overall average than those on greenhybrid. Most on that website tend to be hypermilers and work hard to get the good mileage. I don't know many people that drive to get good mileage. They drive to get from point A to point B. They expect to get what the window sticker says they will get.

Instantaneous MPG feedback on non-NAV HAH? by nowakj66

I just ordered a frost silver HAH and skipped the NAV. Is there any way to see instanteous mpg on the non-NAV HAH to help me learn to drive it more efficiently?

Hi Nowakj66,
 
Imagine there is a big basket of raw eggs underneath your fuel accelarator and try your best not to brake any single egg. That's called the "HAH's Delicious Raw Egg Tactics" which can save your fuel tremendously. Yet, it prevents you from demonstrating your HAH's 255 HP and 232 lbs-ft low-end torque.
