Heating
1 - 20 of 25 Posts
I havent yet tryed the prius in cold weather, but where I live now I am on a small farm on top of the appalachian mountians. So from my long driveway.. guessing about 300 or 400 feet I pull on to a private gravel lane for another 700 feet maybe. After that is a 2 mile drive all down hill, so the engine would never kick on, right? I havent gotten my prius yet so this is all under assumptions and what I read. Would that mean It wouldnt start to heat untill the bottom of the mountian?
What is ICE? Ive seen that mentioned on this fourm a lot but do not know what it is.
Even still... 1/4 mile is impressive. My old car, Nissian Sentra, didnt start to get warm till the bottom of the mountian.

The ICE (internal combustion engine) will start about 7 seconds after powering up. It will run to warm up even if it is not needed to propel the vehicle (i.e., going down hill). In addition the Prius has supplemental electric heat which will come on prior to the ICE coolant supplying heat.
The ICE also has a coolant thermos. This is an insulated tank which stores hot coolant at shutdown. When the Prius is started cold, the coolant is pumped back into the system to help the system warm quickly. All of this is to reduce emissions.

Hey, firepa63,
Just where exactly did you find info on the "supplemental electric heat"? I have been read'g a lot here on this site for over 2 years & I don't recall any mention of this feature until your post. I must confess again that I still haven't read my own '05 manual (if it's in there), but I did read the rental '04 manual from cover to cover for 2 nights in the motel room about 1 1/2 years ago & my memory isn't as strong as it used to be. I assume you are NOT speak'g of the "heated seats" option, of course. If it does indeed exist, how does it work? Thanks.

I can find no other reference to "elec heat" and was unaware of it's existence. Are you sure of this..?

I know there were references to the classic Prius having an electric-assisted heater, but as with the others, I have never seen confirmation that this feature made it to the current Prius. I know that in mine, if I put it in EV mode, then ask for any heat at all, it turns on the ICE.
As for how to warm the car up faster? If you live in an area that gets really cold, you could try an engine block heater.

No I'm not talking of heated seats. There are several posts on the forum about the supplemental electric heat (can't find them right now). I believe DanMan32 supplied the technical information.Ct. Ken V said:
Here's a couple of sources, but I know there are others:

How does it know if I'm in a colder climate? Does the Prius grow a second heater if I move to a cold place? Or does one shrivel up and fall off if I move to Florida? And what if it's cold here, but only part of the year? Or if there's a very cold snap? Or a heat wave?DanMan32 said:
I don't get the "in the colder climates there are two" thing. :?
Thanks for bring'g that up, Sanny.
Yes, Dan, with Toyota's boats hitting the gulf ports then up the eastern seaboard (& dealer swaps too), how is it determined what cars get one or 2 of the "PTC heaters"? New England cars could use 2, but Florida cars don't need both. But they're all on the same boat. Is that why Toyota uses its allocation system, to direct the proper ones to the correct region/district? Or does the port do the extra installations/removals as they are unloaded? Or does the deliver'g dealer do that as part of his PDI? Does anyone know the answer?

Well, if it is the case that the cars are dropped off down here and shipped over land to up there (doesn't make sense since SE is a different ceceeded region), then the repair manual may be referring to Canada as a cold climate region.
Look for PTC HTR 1, PTC HTR 2, and PS PTC HTR relays.
The relays will be located on the firewall over by the spark plugs.
The corresponding fuses will be in the under hood junction/fuse box.
The PS HTR is actually a fuseable link in that white thing.
If these components are there, you have all three heaters.

Is the ICE feature an automatic thing or do I turn it on if I choose. If I get in the car and its cold outside and start the car and turn the heat on does the ICE start to warm the engine automatically. Assuming while that warms the eletric heat kicks in untill the engine is warm enough. Is that how it all works?
Hi, Andrew,
Hope you don't have to wait too long for your Prius. The ICE does not warm the engine. The "ICE" IS your gasoline engine (ICE=Internal Combustion Engine). I think we should have a list of ALL the abbreviations used in this forum to help the newbies here to understand the car & our postings [I think a list already exists for ones such as : ICE, SOC, DTC, MFD, MIL, ECU, ECM, VSC,TPS,OBDII, etc (now I'd like to know what the PTC in "PTC heater" stands for----there are always going to be new ones that need to be added), but it needs to be made a sticky to remain at the top where everybody can easily find it].
Even though you have a long down-hill coast before you need any motive power, if it's cold & you turn on your heater by select'g a blower speed & temp setting on your screen, that will force on your gas engine (ICE) for warm'g YOU. But it should already be running anyway to heat up the catalytic converter & boost the SOC (State Of Charge) of your HV (High Voltage) battery. This is a normal warm-up cycle that forces the ICE to run for a few minutes every time you start the car (even if you just shut it off a couple of minutes ago).
The hot coolant stored in the thermos bottle that firepa63 mentioned earlier is mainly for the engine head to help the gas burn cleaner at start-up [where most other cold gas engines start rough & burn inefficiently (emitting more pollutants) until warmed up a little]. So that hot stored coolant isn't really for our creature comfort although we do benefit in the long run from a shorter warm-up time. I hope this clears things up a little more for you.
I hope the wait for your car is short, but keep on read'g this forum & learn about the car while you wait. Then when you take delivery, you'll feel somewhat like you've already owned the car for a while. Good luck, Andrew.

Edit : I didn't see firepa63's latest post before I started mine. Sorry to repeat more of his info.

Hi, Dan,
No, the cars are NOT all shipped overland. I was told that the boats that pass through the Panama Canal, land at one (or maybe 2) port(s) along the gulf coast (don't know where), then around Florida to one of the Carolina's (I believe Charleston, SC), then at one time Baltimore,MD (but not any more), then lastly the New York port (which I believe is actually Port Elizabeth, NJ). The NY/NJ port serves 3 of the 12 Toyota regions [Boston region=5 of the 6 New England states : ME, NH, VT, MA, & RI (but NOT CT) ; NY region=CT, NY, PA, & NJ (I think) ; mid-Atlantic region=MD, DE, & VA for sure (maybe a couple of other states too). It's too bad that the Southeast region ceceeded from the rest of Toyota & won't/can't offer the Toyota Financial extended warranty, but you guys down south can get parts, treatments, & accessories for your cars that the northern dealers can't seem to get.
I popped my relay cover & I've got PS HTR, FR FOG, PTC HTR's #1 & #2, & CHS W/P (what is this one, please?). Missing naturally is : DRL No.4/RR FOG. I'm curious about 2 things : #1--what does the "No 4" mean & if you put just a relay in that position, will you automatically have the Daytime Running Lights or is it more involved than that (something else required)? #2---what is the RR FOG part of it? If you had it, what would it do/how would it operate? Would it just make the tail lights brighter, turn on the back-up lights, or again, is extra equipment/parts required? Or are OUR NEW '06 headlight & tail light assemblies (with their rows of LED's) not new to the rest of the world that may get the "RR FOG's"? I have not yet had anybody with an '06 demonstrate the LED rows in the front or rear light assemblies.
Thanks for your expert eletrical/electronic knowledge, Dan.
