1) you will get used to the acronyms owning an FEH
2) be careful it only tows 1,000 lb.
In an emergency you can probably tow out more than many 3Ltr vehicles. But you will break your differential.
3) 2006 has some oddball issues. I have replaced three power steering computers and now I have to track down some short in the linkage. Bill at dealer? Too much.
4) learn about your f e h filters as fast as you can. I think a dealer wants to charge me $500 for a stupid filter pretending that it was hard to get to. I was too new to know that it was easy.
5.) Tire pressure is everything for hypermiling. Don't even try to get more than about 30 miles per gallon because it becomes a waste of time in a Prius or an f e h.
6.) The 2006 was a newer invention for a hybrid SUV. The hybrid components are in line with the electrical as first priority and ICE as second priority. This means that you do not have hybrid assistance after about 20 mph. (Conversely, a 2006 Prius can give you 70 miles per gallon at 70 mph. The hybrid components work together instead of a step process)
7) save $8 and just use some metal wire bent in the shape of a U to remove the factory stereo. The factory stereo gets broken on the volume knob for many people. You can try to shoot in some forced air or grease and it will repair for a little while.
8) the truck is pretty. I don't trust it. It's going to be the first vehicle I get rid of out of my four vehicles soon.
9) if you can trust your truck then it is much more comfortable than other hybrids for a long travels.
Couple things I'd like to comment on.
1) completely true, every hypermiler and hybrid nerd loves acronyms and will never explain them.
2) The ONLY, and ONLY reason the tow limit is 1000lbs is because reverse is only provided by the traction motor, limiting the amount of weight you can reverse up an incline. Everything else is the same of the other I4's (2000lbs) and V6(3500lbs). And believe me, It has no problems towing 2200lbs at 85mph up hills. Expect teen mpg, an engine screaming at 4k, and little passing power.
3) These cars are old, and most of the repair manuals are online and available for mechanics. Find a local one, hopefully hybrid specific, mechanic shop and make friends.
4) Completely true, 3 filters Engine,battery,cabin. turns out my 2005 never came with a cabin filter, that explained the leaves flying out the vents.
5) Psi is major, tire alignment is major, A/C effectiveness is major. However, whenever my battery has good days I can easily get 30+ city while delivering all night, with A/T tires and a massive roof rack. (pull the awd fuse, easy 10% mpg improvement)
6) If you are careful with the throttle, you can reach ~40 mph in EV mode, and the 30kw is always available as passing power after that. The configuration of the hybrid system was so similar, that Ford and Toyota came to a technology sharing agreement to prevent a lawsuit. The prius isn't a lifted brick on wheels, so it can slip through 70mph air rather easily.
7) The volume knob is an optical sensor, so you should only use an alcohol spray or compressed air, however my nav system is garbage, and somehow even the clock broke.
8/9) I consider this thing to be one of the best "jack of all trades, master of none" vehicle produced, and I'd trust mine to drive me cross country, on a majority of roads without oil pan destroying rocks, and through water up to the fog lights. I do not trust it to start after sitting 3 days, my battery is just about toast.
