Hi, I'm first time DS owner. Any one knows how to control auto climate control without A/C turning on? Whenever turn on this button with A/C even cold outside and if turn off A/C make auto control off too. Also max defrosted button always turn on A/C too. I need heater not A/C on December.

Welcome to the forum!

I never use the the auto setting - I manually control the climate controls to avoid the A/C from being turned on.
Just turn off the Auto hard button.
Then use the blower control (center wheel).
If you want the vents to come out top or bottom, use the climate control soft button from the home screen.

Here is a Land Rover video showing how to go from manual to auto:

I hit the auto button for climate control, then turn the AC off. The light beside the auto button turns off, but it still does the auto climate control.

Thank you I'll check but I don't know why they set up like that. I have experience previous my car has auto light still on after off A/C that means automatic temp control which is I set up

The last three cars I've had do this. Just because it says a/c is on, doesn't mean it's cooling your car.

My sales guy explained what it all means, but I forgot - Hah. Either way when it's below freezing, the a/c doesn't affect the amount of heat the car puts out. So I just ignore it

In some cars, like my former Audi, I was told that AC is not Air Conditioning, but rather Air Compressor. i don't know if that's the same in the DS or not. I don't know if it's true or not. ;-)

I read a write up awhile back that claims the DS has a very advanced auto climate control system. It's sensors are reading a lot of variables. There's a lot more to it than you think. Auto CC keeps your vehicle temp at a very steady and constant temperature which you set. Jut because the AC light is on does not mean actual AC is running all the time. If you turn off the AC, effectively turning off auto CC, then the system will just blow the air temp that you have it set on at a constant rate and constant temp. Soon you'll find yourself turning the heat down...just like the "old days". I mean, who wants to go back to 1990 right? LOL!
Anyway, with the Auto CC on you never worry about that.

I believe that there is a sensor in the middle of the dash that sense the sun beating down on the car and makes adjustments to the AC system. I saw this in some JLR tech web site.

Yeah that sensor reads a lot of things in milliseconds. Position, intensity and angle of the sunlight, cloudy or shadey conditions etc. The DS even reads humidity and makes adjustments for that.

Actually, you do need the A/C on.
Just like in your house, A/C removes humidity from the air, allowing hot dry air to blow across the glass, instead of pushing all that moisture from snow and ice. Hot dry air is better than hot moist air to keep the glass clear.
Don't worry about it. Today's A/C compressors are a very light engine power parasite and mpg loss compared to the monsters of the past.
