The way I understand it is that if I have it on, no air flow through the vents where no occupants are sitting.
So even if I have the vent open in the back seat, will no air flow through there if no one is sitting in the back?
If I am driving by myself all the time, only the vents on the driver's side would function?

The airbags work the same way. If no passenger the passenger side airbag automatically shuts off.

My odd mnemonic device for remembering the S-Flow...
Think "Green", if you want to save energy/gas,
press the S-Flow button to display green, rear HVAC is now Off.
(There will be a brief drop down banner on the Nav screen BTW)

It seems to me that if you turn off vents in parts of the car where there are no passenger that it would be similar to only having a window mounted A/C in lieu of a central A/C. I like having the entire area surrounding me 'conditioned' instead of air flowing from just a couple of vents directly in front of me. I really don't see the purpose of cutting the air flow to part of the car.

By closing off the passenger vents, there would be more pressure to your vents, cooling/warming you off quicker while the HVAC doesn't have to work twice as hard. The area surrounding you will still be conditioned as it's a tiny area to heat/cool, it's just easier on the HVAC system.

I do notice though that the AC sucks when in ECO mode.

BTW ... even non-Nav vehicles get the brief drop down banner.

I have noticed the same thing and though that it was a problem with my car. So this is normal when S Flow is activated? The full fan speed with S Flow activated is much lower than the full fan speed without S Flow on.
