storing

Fully charge, insure 12 V is healthy. Disconnect 1 lead on 12V or connect 12V to trickle charger. Leave car unlocked, fix trunk to a ajar position ( otherwise, entry by trunk could be a problem ) and...that's it. OR
Give it to a trusted friend to drive.

 

It would be a good idea to store it with a full tank of fuel.

 

If rodents are an issue at that place and time, you might want to place bait or traps.

It's best if engine is hot last time you shut it down before storage, to evaporate moisture from engine and oil.

Don't leave parking brake on if at all possible. Chock a wheel instead.

 

Since we're dealing with an "or more" situation, I would compliment the above with the addition of the appropriate amount of fuel stabilizer.

Additionally, I would "force charge" the HV battery prior to storage.

 

What year and how many miles? I've seen threads suggesting storage can finish off an older HV battery.

 

Wouldn't hurt to bring tires up to max indicated on the sidewall, kinda overkill for two months though.

 

welcome! i've left mine up to 6 weeks without doing anything. two months or more i would follow all the advice above. how old is your 12v?

 

Perhaps the OP is questioning as to specifics with a Prius.
a) I would confirm the tickle charger.
That's more than likely the most important issue I'd look into.
b) rodents....I love that thread on this site.
As with all cars:
c) fuel tank full...some add a fuel stabilizer such as Sta-Bil, as modern fuel seem to "gum up" over time.
d) one window down (or trunk as mentioned above) so you can access in case of total electronic failure.
e) flat spotting of tires...inflate to maximum pressure or better place the vehicle on jack stands.
f) car covers...use it if you got it.

Two months...world wide vacation I hope.
