Active Grille Air Shutter System (Agas) - Subaru Legacy 2015 Technicians Reference Booklet

2015 Legacy and Outback
The Legacy and Outback for 2015 are approximately 10% more aerodynamic. This streamlining is
the result of design changes to the front and rear corners of the vehicle, side view mirrors, under
chassis air flow, and introduction of the Active Grille Air Shutter System (AGAS).

Active Grille Air Shutter System (AGAS)

All 4 cylinder models of the 2015 Legacy and Outback are equipped with the Active Grille Air
Shutter System (AGAS).
The AGAS is designed to improve fuel efficiency by improving body aerodynamics and decreasing
engine warm up time.
AGAS Closed
The AGAS defaults to the open position in case of electrical communication malfunction.
Note: The AGAS is not spring loaded to the open position.
Note: The AGAS will remain closed if the ambient temperature is lower than 37 degrees
Fahrenheit (3 degrees C).
The opening and closing of the AGAS is determined by ambient temperature, coolant temperature,
and vehicle speed.
The three wire actuator receives command signals and transmits its position through a single LIN
communications wire that is routed to the Engine ECM.
