Rear climate control vents?

Rear climate control vents?
Is there any benefit of keeping the rear climate control vents open or closed if no one is occupying the rear seats? Will keeping them closed increase air output in the front? Does keeping them open help cool the car down faster?

For your car's HVAC itself, I would imagine having very little statistical efficiency gains (if any) by closing off the rear vents. The inside of the cabin is the same volume of air - you're either going to be moving a larger volume of air through a fewer number of vents or a smaller volume of air through a larger number of vents. Just like the house example above, leaving all vents open helps to keep the overall ambient temperature consistent between front and rear.

You can turn off the rear vents by turning them All the way to one side...I believe to the left / towards driver side. Takes an extra light push and they go kind of click into off position cutting off the airflow.
This does increase air through the front vents if they are closed.
I sometimes keep them open, sometimes closed. If using ventilated seats function I keep them open as well as the footwell vents to increase cool air getting below the seat.

closing the rear vents just forces more air volume upfront. no harm done. it might be a tad noisier. as for efficiency you're still cooling the same space with the same amount of air. put the air where the people are.

The picture is from my NX, but IS and others with S-FLOW all have the same. Guess your doesn't have S-FLOW though since you're missing the button. Then your only option is to close the vents yourself.
