Quick question , Your on the highway , to cool out for a/c but you want some air in the cabin , no windows down , is there like some vent option / or ventilate option you can switch on ? LS 430 please , I don't see anything

 

You can set the the system to out side air, even if the fan is off some air will come throw. To have more air set the fan sowed to 1 or 2 withe the A/C off.

 

ok so what do I turn on , auto , then how do I turn off a/c? I just want some air to circulate in the cabin without outside wind noise

 

If you have the ML withe nave then use the butone on the left of the screen just abov Auto & off buton. It have 3 light you need to right light to be on.
Then for running the fan withe A/C off go to the climate screen and on the left you will see the A/C virtual butone.
If you have the non navigation then the same.

 

The non nave unit.

 

ok thank you so much I will try those functions , I have the ML system with navigation
