Abstract
A method of controlling operation of an adjustable shutter adapted for varying an amount of airflow to cool a powertrain in a vehicle includes monitoring the ambient temperature. The method also includes sensing an increase in the ambient temperature up to a threshold temperature value. The method additionally includes changing a position of the shutter after a predetermined amount of time has elapsed following the increase in the ambient temperature up to the threshold temperature value. A vehicle using a controller to perform such a method is also provided.
