Abstract
A method of initializing operation of a shutter arranged relative to a grille opening in a vehicle having a power-plant includes detecting a start-up of the power-plant. The method also includes sensing a temperature of ambient air. The method also includes commanding the shutter to achieve a fully-opened position when the temperature of ambient air is above a predetermined value such that a flow of ambient air to the power-plant through the grille opening is substantially unrestricted. The method additionally includes commanding the shutter to achieve a fully-closed position when a temperature of the power-plant is maintained below a threshold value such that the flow of ambient air through the grille opening to the power-plant is substantially blocked. A vehicle using a controller configured to perform the above method is also provided.
