The "Best" will come the first time you reset the average. Then everytime you reset in the future it will keep the highest of the readings between the previous best and the current.

Engine won't shut off when stopped by scposter

I have a 2007 TCH with 40,000 miles. Just recently this started: When I come to a stop sign the engine will not shut off. Also when I put it into park, it will not shut off. After driving a while then it will shut off when you stop the car. If something is wrong, I wonder if this would be covered by the hybrid part of the warranty? Also it will not start driving in the electric mode.

There's a lot of information missing. Like what is the charge on the battery when this occurs? I know that when I sit in park my engine will kick on and off as needed to charge the battery. If it's hot and the AC is running that would make a difference.
 
As for starting in electric mode, I assume it used to or it would not concern you? Mine seldom stays in electric from a start unless I really work at it.

While there isn't enough info about the circumstances, it sounds like you are not getting out of mode 1or 2. I would guess that the computer thinks that some part of the drivetrain is not getting hot enough and therefore wants to keep the engine running to get warm. This would also explain not staying in electric mode when starting to move. When the car is not in mode 4, it will start the ICE when you add gas. In mode 4, you can slowly accelerate on electric alone.

Majority of the time, the engine will start when starting off from a red light - unless you accelerate really slow (which I wouldn't advise with the traffic behind you).
 
Also, what's mode 1, 2, 3, or 4. This is the first instance in which I've heard of it/them.

from the TCH New Owner's FAQ
 
My car acts differently when it first starts up and when it is warmed up, are there different stages?
 
    * The warm up times vary with the temperature as well as use of the car's climate control system. The ECO mode helps, but if the temperature is below 40F, you may see the ICE stay running for a long time if you have the heat on.
 
      The TCH has 4 stages of operation.
         1. Stage 1 is initial warmup. The ICE will not shut off and battery assist is greater than normal. In warmer weather, this lasts a minute or less. In colder weather it can last a few minutes.
         2. Stage 2 is engine warmup. It lasts 2 or 3 miles in cool weather, longer in cold weather. The ICE shuts off if you stop, but will not shut off when coasting.
         3. Stage 3 is partial hybrid mode. The ICE is warm, and the engine shuts off if you coast between 35 and 41mph. If you stop with the ICE running, it will stop after a short time, but stays running once started until you coast (between 35 and 41mph) or stop again.
         4. Stage 4 is full hybrid mode. Enter it by braking to a complete stop (or slowing to below 5 miles per hour) for approximetely 7 seconds or so it takes for the ICE to shut off), it is possible to enter Stage 4. It is hard to know if this ICE shutdown is due to stage 3 or entering stage 4. The only way to know is to accelerate to ~20mph and coast.
            If the ICE...
                o ...continues to run after you stop the car, it is still in stage 3.
                o ...stops within a few seconds the car is in stage 4.
            In stop and go traffic, stage 4 lets the ICE stop any time you coast, instead of having to be over 35mph when coasting. If the ICE is running, turn off the heat and the ICE turns off, you'll know that you are in stage 4.
            If you want to try and force stage 4, the ICE must be running when you stop or the TCH will not enter stage 4, it will remain in stage 3. You can hold your foot on the brake and "blip" the throttle to "start" the ICE, and then enter Stage 4 after it shuts down (~ 7 seconds.)
      Remember, cold weather conditions and turning on the heater may prevent the ICE from stopping (but it will keep you warm, use your own discretion and common sense).
    * Typically how long do the stages last?
          o Assuming moderate (50 to 60F) temperatures when driving on suburban roads (between 25 to 40 miles per hour)...
                + Stage 1 lasts approximately 30 seconds
                + Stage 2 approximately 3 minutes
                + Stage 3 approximately 3 minutes
            Of course, warmer temps reduce the Stage 2 and 3 times and colder temps can greatly increase them.

Is this from Toyota or GreenHybrid?
 
So what stage am I in when I'm doing 30mph, on a slight incline (not coasting) and my battery is driving the electric motor? I don't see these 4 stages covering all the different scenarios.

The info is from Haroldos FAQ on GreenHybrid.
 
The 4 stages is not about which mode your driving in but rather what the computers will do in a given scenario.

Many thanks for the info. I've had my 08 since mid-April. I have no complaints. I'm averaging 39-41 mpg in suburban travel - Northern Virginia to Maryland (1/2 on the interstate and 1/2 on major secondary road). With the weather cooling somewhat, I've noticed a small decrease in MPG.. though from what I've read, I've expected it. It's been interesting "changing my driving style" driving to suit the 08 TCH.. Though the added benefit is that I no longer "speed" as I did in my 02 Maxima (less stressful and lower chance of getting a speeding ticket). Besides, I don't worry about traffic backup on the DC-Loop anymore.

Gatorman -- I am curious about your commute, since I am making a similar trip (from McLean to Laurel). I wish this forum had a private message function so we could compare. I have had my TCH since September, and I am getting similar efficiency.
