Where exactly is this "seat vent" that is mentioned on the Mitsubishi's website? They aren't referring to the should harness holes are they? Surely they would know the difference between a shoulder harness hole and a seat vent.

 

There are 2 horizontal vents in the seat back. You can see them if you sit in the back seat.

 

Are the vents in the plastic shell part of the back seat or higher up?

 

In the plasic shell part.. Both on the top just under the shoulder bolsters and on the bottom near the joint for the back and but area...
