Climate control / heater settings.

[Shaunomercy]

Can someone shed some light.

 

I'm aware the auto on the left hand side of the centre console is for the Aircon on off.

The auto on the left with auto recirculation / recirculation / outside air is on the right...

 

This is where I'm confused somewhat..

 

If I set heater directions manually to wind screen and feet and then press the right hand auto, I get auto and recirculation. In the climate screen it changes the vent direction highlighted icon to feet.

Is this normal behaviour and when does it switch automatically to outside air ? Is there a way of testing it's behaving correctly please ?

 

Is it normal in the climate display to change to the feet icon too?

Hi Paul,

I am not sure why it automatically changes the vents, but I do know that it will switch from outside air to recirculate if it detects certain pollutants from the outside or the car needs to cool the interior down quickly.  It then should switch back to outside by itself.

Funnily enough, the diesels don't have the auto button on the right, but do still switch automatically so I am not sure why.

Yes I think so. The car selects the "to feet" setting when the interior is colder than the desired set temperature. This is the quickest way to heat up the interior since warm air always rises.

Thx j Henderson. That's a relief. The Lexus handbook doesn't cover any of the systems little quirks at all.

Does your car have navigation?

The owner's manual just deals with cars that don't have it equipped. There's a separate handbook for the navigation unit.
