Hi everyone

regarding turning off the auto AC (when turning the heater direction to any windscreen related direction), I have found that on my 09 Rio this mode cannot be turned off.

I tried the following :-

turn heater direction to windscreen (note the AC will turn on).
turned on and off the air recirculation button four times.

I then turned the heater direction to the floor and then back to the windscreen.

The AC still comes on when the heater direction is pointed to any windscreen combination.

So does anyone know how to turn it off ?

It may be the case that only the 2011+ Rios can have this done.
If so then ho hum I will accept but it is annoying.

Hi diddy1234, you need to press the recirculation button at least 5 times within 3 seconds.
'1) Turn the fan speed the "0" position.
2) Turn the mode selection knob to the defrost position.
3) Push the recirculated air position button at least 5 times within 3 seconds
Then the indicator light in the recirculated air position button will blink 3 times with 0.5 second of an interval. Follow the same proceedure to restore.'

Hope that sorts it!

I tried again the instructions phil866 suggested and these did not work.

Any other ideas ?

If it cannot be done then fine, but I had been reading that it can be done.
Is it only Rio's of a certain age that this can be done with ?

They are built to work like that. When set to windscreen /demist the a/c comes on to prevent the screens misting up by removing the moisture that causes it to form. Most vehicles are made that way these day , even those with manual a/c.

Hi guys,

Here is an alternative combination to try. It's taken from a 2012 Rio 3

On my 1.5CRDI 08 model I used to turn heater to windscreen A/C came on, all I did was to turn A/c off and it worked fine.
Hope this helps

I have a 2012 Rio 3 with Climate Control.
I can STOP the auto-demist function by holding down the AUTO button (LHS) and stabbing the Front demist paddle below 4 times in 2 seconds (whatever). However this only seems to work for the current journey - You have to repeat it each time you use the car!! The car appears to be defaulting the auto-demist function ON - and, good as it is tends, to stay on for the whole journey to the detriment of the miserable (and below spec) fuel economy.

If anyone know a way of changing the default setting I would be pleased to hear it!

I followed the procedure in the owners manual and the auto defog was switched offUnfortunately this had to be done every time put the key in the ignition!

It does seem silly on a car boasting about the MPG that the default setting is to run with a/c on! i do a 70 mile trip and was having to have a/c on when it was 5C out side !!

My '07 Rio diesel has been unresponsive to all these fixes. Has anyone put an inline switch in the circuitry to "cure" this issue? I'll certainly want to try this fix regardless of it having been done before or not but I don't want to reinvent the wheel if someone can point me to the correct wire(s) to tap.

I have had my Rio 3 into Kia for a weekend to cancel the A/C in auto front defog.
As has been said - the handbook does tell you how to switch it off but it also implies that this is permanent fix and has to be redone if you want it to revert to the original setting. After confirming with the Kia main office this was found to be inaccurate and was told the handbook is wrong and will be either reprinted or they may do a software update in the future.
It is worth mentioning to your garage whenever your Rio is in for service/repairs to check for software updates.

My garage is on the end of my drive.
I'm strictly a DIY man. Having built a twin turbo v8, spaceframed Reliant Kitten in the past, most jobs are within my reach. Plus I hate paying others to do something I can do myself.
