will the lc 250 air conditioner function when the motor is off? some of toyotas other hybrids rav4/prius have this feature.
 
Short answer is we don't know yet.
 
Short answer is we don’t know yet.

Long answer is it should, since other toyota hybrids including the tundra have AC compressor that is not engine driven.
 
My 2022 Toyota Hybrid will operate all Night if that option is selected… otherwise it will turn off at 1hr

The HVAC will stay operational… and the engine kicks on for a minute to charge battery few times per hour.

This has been done with the Prius for years … car camping. Look up YouTube videos.

Used like 1.1 gallons of fuel for that time.

So it should be same as any other Toyota hybrid.
 
I understand the electric motor is situated between the ICE and the transmission.

So unless the AC compressor is electrically driven vs a legacy belt drive unit, I don't see how the air conditioner will function without the engine running.

Edit: I can't quite make out which accessory is the AC unit this image, but perhaps this is it; whatever this accessory it may be electrically driven:

The Tundra hybrid is an electrically driven AC unit. I'd guess that red circle is the same unit. It is a hi-voltage system component apparently. This is from the Tundra manual and letter F is the AC compressor:

Also while reading it - this is unusual and I don't know how to interpret, but seems to say that the hybrid system will only work if it has a minimum of 5.5 gallons of fuel. I think it really means that it takes 5.5 gallons to turn the low fuel light off, and that it won't try to start the engine after running out unless it has enough fuel to turn off that light. That's pretty unusual IMO. If I ran out of fuel and put 5 gallons in - I would not expect to still be a gallon short of starting the truck. That should not only start it, but give you about 100 miles of range. I guess you'll need at least 4 rotopax, or two useful size gas cans.

"Note: Running out of fuelWhen the vehicle has run out of fuel and the hybrid system cannot be started, refuel the vehicle with at least enough gasoline to make the low fuel level warning light ( Low fuel level warning light) go off. If there is only a small amount of fuel, the hybrid system may not be able to start. (The standard amount of fuel is about 21.9 L [5.8 gal., 4.8 Imp. gal.] when the vehicle is on a level surface. This value may vary when the vehicle is on a slope. Add extra fuel when the vehicle is inclined.)"

In my Tundra (2016) the fuel light comes on with around 8 or 9 gallons left. I wish Toyota would give a more accurate meter on how much fuel I really have left. I hate trying to guess and hope for the best. Especially when I'm towing.

You answered your own question — the AC on the Prius is driven by electricity, not a belt.
 
Prius will run AC with the car 'on' and just use battery until it drains. Not sure about the newer hybrids. Will the new Sienna let you have the AC on and still lock the car and walk away? That would be awesome for pets, like the Teslas do.

Yes, hence the edit. I wasn't aware of how the Prius's system works until now.

The more you know!
