Aloha, Over the holidays, I got a puncture flat in my rear driver-side tire (nail). The local tire place fixed the tire fine, but as other members have...
I too would like to run my defrost without the compressor or the ICE. But would you really want to disable the compressor? The ICE will start to cool and ...
There is a wire that connects to the heater control ( I think it is pink and white on a 2005). If you put a switch in line with that you can turn off the...
Cohybrid, John is talking about when the outside temp is below freezing, the compressor is disabled and the ICE will shutdown even in the red zone of the...
From my tests, the FEH tries to maintain ICE head temp at 74C, will start the ICE when head temp hits 64C in cold weather and conditions conducive to ev under...
#1 I was speaking about the A/C automatically being disabled below 32'F. I have no switch. #2 I have never had the ICE shut down with a red defroster setting,...
I am looking to purchase an '08 FEH when the come out (around April I hear) and was wondering if anyone knew of any good websites where you could get consumer...
I remember reading on here that there was a TSB regarding a problem with the NAV losing its way from time to time. After some diligent searching, I can't find...
John, the ABS may have also cancelled regen and allowed the shutdown of the ICE like I've been posting about with the neutral brake tapping. That's what the...

... We did that for about an hour with a baby in the car while some other kids were out playing in the snow. It was someone else's baby, and she was going to...
This leaves a gap in reasoning as to why the ICE must be on with defroster on when below 32F if ICE isn't needed to run the A/C compressor, as it is when above...
I honestly don't know what is wrong with a good old fashioned A/C button on the control panel. A lot of cars have one so the drive can have direct control over...
I can understand requiring the ICE to be on whenever the defroster is on. The defroster is used to gain a safe view through the windshield, and having the ICE...

I am always surprised at how the same car manufacture uses different technologies in the US and Internationally. I drove a Ford Focus in the UK that had a...
... My ICE stays on at several times that I can't figure out ;-) I was sitting at a light, reviewing the conditions, wondering out loud why the ICE was...
Don't see why it would be any faster since ICE keeps its temp in the operating range anyway. All the defroster does, when the A/C is disabled under 32F, is...
That make sense Clarence. The reason I agreed with GPSman with the shutdown, was the post on GH that stated that both his '07 and a friends '05 FEH/MMH had...
Gerry -- Welcome! You're now "hooked"! This is a great forum for technical folks like yourself. I love my '05 AWD. Have about 30,000 miles on it. Don't...
John -- Whoopee! Thanks for sharing your experience. As a Northern Nevada resident, I also experience similar conditions on occasion. Nice to know that I...
There are two main phenomena that cause the on-off cycling of the ICE on a level road at a given speed: engine head temperature and battery state of charge....
... NO! Does is make sense that burning gas 100% of the time is better than burning gas 99% of the time? Would you rather burn 1.00 gallon per hour, or 0.99 ...
... Depends on if starting the engine requires more gas to get it to roll over than it does to just keep running. MOST engines require more gas when they roll...
You must live an a linear world. If there were no cost to restarting the ICE and recovering operating temperature, then why not let the engine temp drop below...
In cold conditions, in addition to the rollover cost, you will also have to run the ICE longer and/or at higher rpm to recover the operating temperature while...
... Are we sure the AC is disabled completely? It still needs to dehumidify the air from time to time, so maybe it's in "standby" rather than disabled, and as...
I was trying out some of the hyper mileage tricks including using "L" more often. This was working great until I was decelerating from about 60 MPH. I let...
