Since i´m not yet a Prius owner I´ve have got lots of questions about the car that most car dealers can´t answer. Lucky me who has found this place....

So, for how long can I run the ACC before the ICE kicks in? I park the car with, for example, 6 bars of battery power in the sungaze and gets back to a hot car. Will I be able to run the ACC on only battery for a while to cool the car without the ICE starting? Just like 5 minutes or so to prevent me from getting a total brain meltdown.

Also, is it possible to progam the car to cool down on a specific time? That would be a great feature!

If the car isn't Powered on, the A/C doesn't work. The 12V battery can't do everything. No set time for ICE restart, just battery level...

Sorry Sprett, I'm confused by your question.

ACC = Accessory mode. In a regular car usually you turn the key backward one click or sometimes forward to the first click and it allows simply things like windows up/down, headlights, radio, etc.

A/C = Air Conditioner--is that what you meant?

A/C will not run in ACC mode in the Prius. If you leave the car in Ready mode and run the A/C it will run for a varying amount of time before the ICE starts up depending upon:
1)SOC of the battery when you stop--if you're at 2 bars it'll probably keep running for a while to increase the SOC before it stops. If you're at 8 bars you might get 10-20 minutes of A/C bofore the ICE needs to kick in...maybe even more.
2)How hot it is outside, if you're sitting in direct sunlight, how cool the car was before you stopped.
3)How cold you have the A/C set. If you've got it at Max Cold the ICE will run almost continuously in a very hot environment. If you just need a little cool air blowing on your face and aren't trying to make the entire car a refriderator you can turn the setting to 80 degrees and point the vent at your face...park in the shade and you might get a good 30 minutes of A/C before the ICE kicks in if you started with a relatively high SOC.

Sorry for not being clear enough in my post.

For me AC stands for air conditioner, meaning I have to adjust hotter or cooler. ACC for Automatic Climate Control, meaning that I just tell the desired temperature and the car does all the adjusting.

So, again, with 6 bars of battery level and a sauna hot car, will I be able to get it to room temperature without the engine starting?

Again, maybe. What's "room temperture"...what setting. Are you starting the car into ready mode and using your EV button? Why is it important to you whether the ICE starts or not?

I understand wanting to be comfortable in your car while you wait, so I understand that you want A/C, but why are you concerned about whether or not the ICE starts. I say just put the car into "Ready", turn on the A/C, and if the ICE starts it starts. If you use your EV button you can probably get the cabin to room temp (say 79 degrees) from 6 bars before the SOC gets so low that the EV mode would cancel and ICE would start up, but it probably couldn't sustain it for long.

I usually just roll down the windows and listen to XM radio in ACC mode until it's time to go, then crank up the A/C and roll up the windows once the car is moving.

Well, in Sweden it´s against the law to idle your engine for more than one minute. So, guess again, why do you think I care if the engine starts or not?[/quote]

Ah! I would say that it's unlikely that even should the ICE come on that it would idle for more than a minute. Not impossible, mind you, but unless you've got a cop with a stop-watch standing there timing you I think you're going to be OK.

wish we had a law like that over here. People idle their cars while waiting just to keep cool. I mean, just wind down the windows. It's not like it's 40°C outside.

anti-idling laws

most of the anti-idling laws and info I've seen has been from Canada. Too bad it is not more widespread, and it's rarely enforced...

It is illegal in Massachusetts to idle your vehicle for more than 5 minutes (except under certain conditions, which does not include warming your car up in winter).
Mass. General Law, ch. 90, section 16A:
http://www.mass.gov/legis/laws/mgl/90-16a.htm
http://www.state.ma.us/dep/bwp/daqc/fil ... /7b.htm#11

I see that the city of Toronto (Canada) and that London (UK) have also implemented city by-laws against idling of engines, as they're mentioned as case studies at the Idle-Free Zone toolkit site from the OEE (Canada):
http://oee.nrcan.gc.ca/transportation/p ... idling.cfm

Ottawa and Montreal in Canada also have an anti-idling law:
http://temagami.carleton.ca/jmc/cnews/01022002/n1.shtml

I'm certain that there are other towns/cities/counties/states that have similar anti-idling laws, but I haven't found them yet...

More information about idling vehicles (why it's better to drive it than idle it, how long of a warmup your vehicle really needs, etc.) can be found here:
