Ventilation System Question
Has anyone figured out how to turn the ventilation system on without having to turn on the A/C? I usually leave for work early in the AM and don't need the A/C, but like to have air coming into the cabin. The only way I have been able to figure out how to do this is to hit the auto button and then the A/C button to turn it off.
Thanks in advance,
Rob

Temp setting.
Is there a reason you turn the temp all the way down?
I also press the A/C button to off when I want just outside air. There's no other way that I know of either.
There isn't a need to turn the temp all the way down to Lo. But it does need to be set at or below the outside temperature, otherwise the heater will kick in.

I may be missing something. I always leave the system on "Auto". If its too cold, I turn the temp up. Too hot, turn it down. I dont play much with the fan setting or anything. Then again, I live in Seattle, so its rarely in one extreme or another where I have to think about it. The car manages everything just fine for my taste. My wife (and even a friend I let drive my old TL) futzed with everything and had the system doing all kinds of weird things. I couldn't understand why. I just sort of assumed they dig the old school of HVAC.
Does Auto not do what you want, or am I missing something more?

There is a way!
Turn off the havoc system all together.
THEN....hit the mode button. This will select JUST outside air and where you want it to come in. No fan will run at all. The system is off but you will still see the icon in the display where the fresh air is blowing.
Does this make sense?
Bottom line is. Hit the "Off" button and THEN hit the "MODE" button.
You will have only fresh air with no fan.
Try it and report back.

i have navi and what i do is if it's in AUTO and i want my windows down, i hit the down button. the AUTO disappears and a bar that represents the flow of air appears. i lower it to 1 bar and that's it. once i want to roll up the windows i hit AUTO again. is that right or am i still running the A/C
flnsx: i'll try that right now. i'm leaving work

tried your method and all it did was it cycled to the next MODE. is it different for non-navi?

I think you still run A/C that way.
When I want fresh coldest outside air without A/C, I turn the system on by
"Auto"
"A/C" (AC goes off)
"Temp down" (to LO - I was thinking if temp wasn't low, heated air would mix into cold air to make moderate temperatured air)
"Fan up" (you want fairly high fan speed)

Keep Right Except to Pass
If you have Navi, you can say "Air Conditioner off" to turn it off, "Fan speed <X>" (where <X> is a number) to set the fan speed, and "Climate control vent," "climate control floor," etc. to tell it where you want the air to come from. You can also use the "Mode" buttons for this last step and the fan speed buttons for the second step. I usually leave it on Auto myself, but when I do want to change it I don't much like fiddling with the buttons in traffic so I tend just to use the voice control.

See that's what i luv about this forum you learn something new every freakin' day!!! So in my case, when i'm leaving for work in the mornings (not until around 9:15'ish) and if it's too hot outside and not even if it's too hot, but just a matter of me not wanting my windows down, i ALWAYS just hit the Auto button. I keep the temp. around 73 and the fan speed on 1. So are you all telling me that by doing this, i'm actually running my AC??? So in my case, i would just need to hit the AC button in order to turn it off? Let me know. I'm wanting the outside air to blow in.
BTW... I have Navi.

I suggest you first verify that indeed when you adjust the fan speed, the "Auto" disappears. Then determine whether "A/C On" or "A/C Off" is showing in the display where the clock is. That will tell you your answer.
#18
Ok so when i initially hit Auto, and say i hit the fan speed button, it takes it out of Auto. However, is the AC still running? I'll definitely look more into this when i get off work and get back into my car. So basically if i hit Auto... to make the AC not run, i need to hit the AC button and i should see the "AC turned off" (or whatever it says) correct? So as a result of this, will that keep it in Auto mode?
#19
The "auto" will always disappear when you hit another button, except defrost, rear window heater, dual, and the temperature controls.
No matter what else you do, you have to manually push the A/C button to turn it off, and either push it again or press auto to turn it back on. And pushing the A/C button will take it out of auto.

This is so far my understnading on this system
Sitaution #1 - You start system by pressing "AUTO"
You are almost guaranteed to have A/C on because auto really keep the A/C running exception of "hi" or at below freezing point.
Situation #2 - You were in "Auto" now u pressed fan speed
You are still running A/C and wasting gas. From what I've read from manual, you only control fan speed but everything else (outside/inside air, A/C on off, mode) are still controlled by computer
Situation #3 - You were in "Auto" now u pressed A/C off
You will understand what I said in #2 here. Set the temperature close to low in auto mode then turn the A/C off. Fan speed increases to keep the car at that low temperature. So you now turned off A/C but car is still in control of fan speed, mode and other things
I think car does mix the hot and cold air if you don't lower your temperature all the way when you are not using A/C. so keep the temp low and A/C off for fresh coldest air possible.

And so as a result of you "Situation #3, by turning the AC off, this in turn will reduce the amount of gas that's being taken as well right? It won't have anything to do with you having it on a low temp. or blowing the fan speed say around 4 versus 2?
#23
Fan 4 will take more electricity than Fan 2 for sure but it won't be anything comparable to using AC.
Temperature setting while AC is off is solely mixing hot and cold air and does not use any extra gas.

Ok i'm still missing something here... So when i got in the car yesterday evening after work i pressed Auto > then pressed the AC button in order to turn the AC off > then i lowered the temp. to Lo; however, it was just HOT AIR that was blowing out! What in the world is going on? Is it because i need to press the button that gets the air circulating with inside the cabin? B/c that wasn't pressed. I waited to see if it would cool off but unfortunately it didnt. Is it because it's bringing in the fresh air from outside? Which means that if it's like 86 degrees outside, then that's what it'll blow inside?

Ok cool. So then why do people do that then?... as far as turning the AC off and putting the temp on Lo? If that's the case then wouldn't you just want to roll the windows down? You'll still be getting the fresh air coming inside
#27
When it is cool outside and I don't need ac, I hit auto and then turn the AC off since I don't need it. I leave the temp in a normal range (70 ish). In the summer, I just hit auto and leave it in auto with the AC on and again the temp around 70-74 depending on how hot I am. I have no idea why people would lower the temp all the way with the ac off, since the system can't cool anyway. Also, if you have the temp all the way down or all the way up, the fan runs at maximum, so then you have to mess with the fan also to keep it from blowing you out of the car.
If I put down the windows, I just turn the whole system off. No sense in running the fan if the windows are down.

I think (I am about 60% sure) if you don't put ur temp to LO, you are mixing hot air with cold air into cabin.
Rolling down windows and using ventilation is different. Especially if you are sitting in traffic(where do u get air if u roll the window down standing still?) or at high speed (do u ever notice women doesn't like messing their hair?)

Bottom line, if you are hot just hit auto and it will run the AC for you. If you are not hot turn off the AC and get a little better mileage. Open the windows if you want and turn off the system completely if you want, or let it run on the fan, just the fan doesn't matter much anyway.
Personally, I hate that is runs the AC all the time in Auto. There is just something strange about having the AC running when it is cold out.

The owners manual states it runs the A/C to dehumidfy the interior air. It's a similar climate control system on my wife's Honda Pilot. Both run at high duty cycles even when the outside temp is at or below the inside setting.
I agree it is a waste of fuel.
