Basic question. I’m still fine tuning the settings on the new 350 ES I’ve had for only a few weeks now.
I’m in FL and in mornings would like fresh air without a/c compressor to run. There was a setting that said “A/C off” for it that I chose. So to thereafter activate a/c, without having to dive into settings every time, do I press auto? I would like to manage manually using temperature gauges, etc. Former cars had “Econ” setting, which was new air without compressor. No such option apparent on the dash. Can someone explain. The instructions are a bit unclear to me.

 

I believe once you turn off AC, AUTO will not turn it back on. I never touch it though - AC on even during the winter here in the NE.

 

I'm not sure which setting you are talking about, but, if it is the one that I think it is, you should be careful about whether you really want to use it because there is a significant downside to that setting.

Yes, it will allow you to turn the AC compressor on and off without going into the menus, but what that setting also does is that, whenever the AC is turned on, it will only operate in the recirculate mode, and it will never operate in the fresh air mode. The result of always operating in the recirculate mode can be that it can cause the air inside the cabin to have a "stale" feeling.

 

There is also an ECO setting (separate from the AC on off) but that merely limits the AC operation in some way to conserve energy and make you uncomfortable. Can't imagine why anyone would use that.

 

If only as a matter of curiosity, is that eco setting deep in the menus? It’s not on the dash.

 

Purpose is to enjoy the wonderful morning air here in southwestern Florida and in PA in the summer.

 

Better to leave the compressor (AC) operating in Auto Mode and just flip from recirc to fresh on the right side.

 

I think that is a reasonable solution, but, for that to work, the OP can't use the setting that I think he/she is talking about. With that setting, whenever the AC compressor is running, the system will always be in recirculate mode, and, whenever the car is in fresh air mode, the AC compressor will be shut off.

 

MENU/CLIMATE and then you get this screen:

 

Nice - where in SWFL are you? We have a place on Sanibel Island.

 

Our place is on Marco Island. Spend the 4 winter months here. Love it out your way, too. Bubble Room!!
Just bought our new Lexus here, at Pembroke Pines.

 

Thanks much. That’s helpful. Just got the car and still not real efficient at navigating all those menus.🤔

 

Love the cakes at Bubble Room! We don't spend enough time down there but maybe soon. Will be down in another month or two one way or another.

 

It’s been lovely here the past month.
Great place to enjoy a Lexus!
Have you dealt with any of the Lexus franchises down here for service? Germaine Lexus is in Naples. Closest probably to both of us.

 

There's one in Ft Myers as well which is closest to Sanibel. We typically fly down though as our stays are only a week or two at a time.
