No I haven't tried turning the temp to LO. But you're making my point. Doesn't this defeat the theory that "If the car is significantly warmer than the desired temp, the system auto kicks in with the "max air" to rapidly cool the cabin". As many have said prior. This also defeats the theory that this system is something better than whats used in other cars. If this is truly the case, one shouldn't have to lower the temp even more, then raise the temp later. Again, if this is truly some nextgen smart system, this shouldn't be necessary as thats exactly what we used to do back in the 80's before CC. (The need to turn the system all the way down to cool the car in a hurry.)

If the car has done away with a MAX AIR button for this purpose, the only logical reason should be that the system is intelligent enough to know that the ambient temp is far higher (when you first get in a hot car for example) than the target temp on the dial, and makes a intelligent decision to max air the car to get the cabin to where it needs to be as fast as possible.

To be clear -

I do not touch anything when I get in the car. If it was left on auto, and a temperature lower than the temp the cabin is at - I get the same effect as a "max" button - maximum cold airflow and raised vent. I don't have to turn to low, press any buttons, turn any dials - it just works.

Sounds like a problem with your car.

This is how mine behaves.

That is essentially what we have. HI or LO will override the automatic settings and give you maximum heat or maximum cooling with no interferance. Otherwise you set the temperature and the system does what it needs to get you there.

It's really not any different to that in the X351 which you had before your F Type, or the X350/X400/X250 generation before that. The auto button merely enables auto mode - exactly as it does on any other car. I am struggling to see where the confusion is?

You have two modes - manual control where you can set the fan speed, termpature of the air and the vents to use. Or you have auto mode where you set the temperature and the car will make adjustments as needed.

I note that as yet no one has viewed the PDF I attached to my last post. It explains how the different sensors are used in auto mode which you may find useful.

As your primary concern appears to be getting into the coupe when it is hot and rapidly cooling it down, simply turn the temperature knob to LO and leave it till you start feeling cold, then turn it back to a comfort setting. Unless the car needs to override your choice to avoid misting (all explained in the PDF) you will get the result you want which is maximum cooled air. Do you live in a particularly humid climate?

However as others have mentioned, if the car is notably warmer than the desired comfort setting then it will attempt to cool it down within a couple of minutes anyway. The greater the difference the more the airflow.

And I will tell you again that this behavior does not match what my car does.

The operation of this system is blisteringly simple: You leave it on auto. You leave A/C on. You dial the temp. Activate your defogging options whenever needed with a button press.

Center vent goes up when cooling. Period.

System blows harder when temp difference is greatest. Period.

Desired temp is reached within minutes. Period.

I suppose this may be necessary if your car is not functioning as designed. I would prefer to get the problem fixed.

Default Nati. I'm not a six year ago old my friend

I told u my system isn't working properly. Telling me how easy the system is to operate doesn't solve anything for me bro.

I honestly cannot tell from anything you wrote that your mind was made up about that fact. You said perhaps, and then you went on to refer to way the system is supposed to work as a theory. I hope you get it fixed easily.

Something wrong with your car (and I have the Coupe). If car is hot when I get in it, the vent will always rise and go to max cool if the Auto (CC) is turned on. The touch screen customization settings for the system (similar to the custom settings for dynamic mode) are only there for the idiosyncrasies of individuals. For example: if someone has poor leg circulation and needs more heat directed low rather than high. I've never felt the need to teak the touchscreen settings.

Works great in Vegas! Use manual mode with temp at 65 and vents set to upper only. Use recirc as needed and fan to adjust as car cools down. Dash vent always up when on. When heat on use same method but vents on all. Never use auto.
