Off Mode
WARNING: This page is about a different car, the 2004 Pontiac Vibe. However, it is still accessible from the selected car via links, so may be relevant.
When the OFF position is selected, any A/C request will be cancelled and the A/C indicator will turn off. Fresh air will still be brought from the outside and the temperature and mode controls will continue to function only to manipulate the fresh air that enters the vehicle. The recirculation function can still be activated which will bring air from inside the vehicle instead of fresh air from the outside.
