I was a bit surprised to find that the 2008 HiHy fuel system is unique from every other vehicle I've owned. Now I'm curious as to what it's really doing. When you press the Fuel Filler Door Release button, the Owner's Manual says that it may take up to 10 seconds to release the door and that the Multi-Function Display alerts you to when the vehicle is ready to be refueled. It also mentions that it is releasing pressure from the system and another section in the manual, about unusual noises from the vehicle, mentions that you may hear a hissing sound about 5 hours (I think this is the correct figure) after shutting off the vehicle. It says this is a leak test for the system. I know that this must be part of the SULEV (Super Ultra Low Emissions Vehicle- Zero evaporation) compliance system, but I'd like to know more about what it's actually doing and how it works. Does anyone else know more about the fuel system in the 2008 HiHy and what it's acutally up to? Does the previous model HiHy also work this way? Does it normally operate under pressure? Inquiring minds want to know! |

I was driving in the Econ mode. I expect that this will improve with further break-in of the engine components. |

| My wife and I are looking at the 2008 HH and this is partly due to the fact that she will not drive a Prius. But, to get to my point, there is a company that is developing a battery pack for the Prius and soon for the HH. The company is HiMotion. I think that for short, around town trips, your HH could get awesome gas mileage. I look forward to getting the HH after we get back from vacation. I also look forward to getting more information on the battery pack so my wife can go longer between trips to the gas station. | |

We've the happy owners of a 2008 HH Limited with about 600miles so far. We're in a fairly hilly portion of Oregon doing mostly errands, but I'm only averaging around 21mpg. Anyone else have experiences with the 2008 they can share? |

Replying to: mesadog (Nov 01, 2007 2:45 pm) I am from Edmonton and I bought HHL-06,19K miles with NAV from USA. I am trying to convert convert digital odometer reading from Miles to Kilometre and to degC. Do you have any idea? I contacted local Toyota dealer and they cannot figure out this change to Metric without changing odemeter cluster. Any help is appreciated. regards, Steaman

Replying to: steaman (Dec 21, 2007 6:49 pm) The vehicle passed both federal and provincial inspections easily, no repairs or mods at all. How are you finding the vehicle ? Over all I am very happy, but the magnitude of the decline in fuel efficiency in colder weather has surprised me. With my mix of driving I was getting about 25 mpg when the cold hit and now I am about 20% lower.
