ACTIVE AIR SHUTTER SYSTEM

id092300700000


Outline

•  The active air shutter system controlled by the PCM reduces turbulent air*1 occurring around the vehicle which reduces air resistance. It does this by closing the active air shutter behind the front bumper mesh while the vehicle is being driven to control the air flowing into the motor compartment.
*1  :The air flowing into the motor compartment from the front bumper mesh while the vehicle is driven flows underneath the floor and the tire housings. The air flowing underneath the floor and tire housings collides with the air flowing around the vehicle and creates turbulence.
