Do I need to disconnect the 12v battery? Do I need to pull the fuse for the main battery? Can I put a trickel charger on the 12v batt while I am away. Should I do nothing and charge the 12v on my return before attempting to start?
Personally, I'd probably just do nothing. But a trickle charger on the 12V battery might not be a bad idea.
There's a pdf floating around here, Toyota's guidlines. Some thoughts, hook up an intelligent charger, ie: one capable of reducing charge and then switching to maintenance charge. CTEK 3000 is one. Just leave it on. Do nothing to the main battery. For the tires Toyota suggests to pres. up to max sidewall. Assuming garage kept, I'd suggest to put the whole car on jackstands, so the tires are just an inch or so off the floor. Put rags under your wiper arms to keep them off the glass a bit. Gas up, and put recommended amount of a fuel stabilizer in. Leave a window slightly open. Lessee..., that might be it
There was the TSB at http://priuschat.com/forums/gen-iii...-dead-after-17-days-parking-2.html#post955609. I'm not sure if there's a newer version of it.
