#35 of 84 consumption up the junction by gazguzler Oct 11, 2005 (1:47 pm)
Replying to: jslate (Oct 11, 2005 9:59 am) I'm noticing a precipitous increase in consumption. We had terrible rains over the weekend and the temperatures have plummeted. The annoying engine-starts for no reason are more frequent. In the rain, it seemed that (maybe my imagination) when I went through deep water that would cool off the CC and then the engine would start again to warm it up. If I find the thermostat for that I'm sticking it in the cigarette lighter to fool the computer. I was getting darn close to a 30mpg average but it’s going to head back down now, I can tell. And all for this maddening reason of using the engine as a heater for things that could be heated when they’re actually used and needed.   Anyone else getting this? Anyone know where the sensor for the CC is? Replies to this message: cdptrap (Oct 11, 2005 2:48 pm) 650vac (Oct 11, 2005 3:11 pm)

Replying to: gazguzler (Oct 11, 2005 1:47 pm) No clue where the sensor is but have now encountered frequent engine warm-up cycles as well when starting and driving in cold temperature (hi-40's) last week.   Instead of warming for 30 seconds, the engine stays on longer now. It also comes on twice more in the 3.5 mile drive to the freeway. I used to be able to nurse it on electric all the way to the freeway without the engine, no longer true.   Each 30-sec burn eats up 0.2 MPG. Each >30-sec burn (1 min?) eats up 0.3 MPG. So in our 3.5 mile trek on a cold morning, after a total of 3 burns, we are losing 1 MPG due to engine warm-up.   I read somewhere it is warming not just the CC but also the engine oil. Because the engine has to turn ON and OFF instantaneously without some sort of pre-spin (idle), the engine oil needs to be warmed properly to protect the engine when it spins up to high RPM to provide power. if I can find the source again, will post this info.

Replying to: gazguzler (Oct 11, 2005 1:47 pm) Just a guess but if it doesn't take engine oil temp into account I would think it may get the temp from the O2 sensors.
#38 of 84 Re: Trailer Towing experience [jslate] by gone2fish May 16, 2006 (12:13 pm)
Replying to: jslate (Oct 11, 2005 9:59 am) I'm considering buying a HH and wondering about towing a 3400lb tent trailer with brake controller unit. Have you wired a break controller unit on yours? does your trailer battery charge while driving? How is all this working for you? For the 5 times per year I tow a trailer on vacation, I'd be happy to get 15mpg, if I could increase my gas mileage when not towing.

#42 of 84 Wiring the Tow Package by deckwench Mar 28, 2006 (9:24 pm)
The Toyota dealer slapped on the burly-looking tow rig for our new HH. It comes with a 4-pin plug. The dealer's service department does not do the adaptor to handle a seven-pin, so our local RV store will be doing that. They've never done a hybrid before and I'm wondering if anyone's had any experience with the brake wiring for an HH? I sure would love to save the guys down at the RV shop some of their very expensive time. Replies to this message: gone2fish (May 16, 2006 11:45 am)

Replying to: deckwench (Mar 28, 2006 9:24 pm) Did you ever get info on this? There should be an adapter that you could buy to convert 4 pin to 7 pin. I am considering purchasing a HH to replace my Durango to conserve gas, and aid in greener emissions but am concerned about towing performance with my 3400 pound tent trailer. How has your experience been? What weight trailer are you towing?
#44 of 84 HH handle sand and towing by colley Apr 25, 2006 (4:00 pm)
I read the post about off road driving, but it didn't mention sand, as in the Outer Banks. Does anyone know how well the HH handles sand and towing a camper? Replies to this message: cdptrap (Apr 25, 2006 4:56 pm)
