Ventilation outlets in liftback?

[tomlin99]

Hi all,
I'm new to the forum and this is my first post. I recently purchased a 2008 Yaris liftback (auto, power package w/15 in. wheels). I'm really loving the car and the mileage (first 3 tanks have been over 40 mpg...I live in an area where the speed limit is 55 mph so I'm getting max. mileage at about 60 mph). I'm planning to completely disassemble the interior and add sound deadener this weekend...got all the materials and tools ready. I'm trying to figure out where the air exhausts out of the rear of the car. I don't want to cover the areas in the back where the ventilation system exhausts the interior air with sound deadener and block the air where it exits the vehicle. Does anyone know where the ventilation system exhaust areas are? I've tried everything to get this information online and have had NO LUCK...appreciate any help...
