    It blows into the rear trunk area, then get sucked through the interior panel via that one singular vent. That vent is also your pressure regulator when you close the rear hatch... don't want to blow out the windows after all.

    C1 is less efficient in dissipate the heat since it doesn't have the cargo cover to "help" direct the flow of air.

    Glad I found this thread. I have a 2004. The cabin air is blown over battery then funneled by a duct to the outside via vent (above the 12V battery) with flexible flaps. My question is: why is the air vented? because it is simply warm?....or because it has some potential battery fumes? (if such a things exists)

    Okay, I've read all these posts and I still don't know the answer here.

    Does the battery vent fan (under the seat) direct air OUTSIDE of the vehicle, or back into the cabin?

    It vents back into the cabin. There is a diagram in post #16 of this thread. The exhaust vent is in the back hatch area on the right.

    G'day,

    You could take the hint in dubit's avatar.
    Find a smoker, and with the car running, get him-her to puff into the space near the assumed exhaust vent. This may show where there's air movement.
    If you have a young child, borrow their bubble mixture and see if the direction bubbles float helps answer your question.
    A less graphical method could be to lick one side of your finger and hold it in front of the boot/trunk vent - see if the cooling effect indicates suction or blowing from the vent.
    A piece of Gladwrap (very thin polythene film) briefly held over the vent could also show the direction of air movement.

    Could be a useful occasional check on how well the cooling system is working?

    Let us know 'how the wind blows'.
