1. An air flow control system for an off-road vehicle, comprising:

  • a first movable side panel configured to be positioned proximate to a first lateral side surface of a body of an engine hood of the off-road vehicle; and

    a controller configured to;

    receive a signal indicative of a temperature of an engine of the off-road vehicle;

    access a desired engine temperature range from a storage device;

    output a first control signal to instruct one or more actuators to move the first movable side panel laterally outward relative to the first lateral side surface of the body of the engine hood to enable a flow of air through a gap between the first movable side panel and the body of the engine hood when the first signal indicates that the temperature of the engine of the off-road vehicle is greater than the desired engine temperature range during operation of the engine;

    output a second control signal to instruct the one or more actuators to move the first movable side panel to a closed position in response to shut-down of the engine of the off-road vehicle;

    receive an operator input to close the first movable side panel via an input device; and

    output a third control signal to instruct the one or more actuators to move the first movable side panel to a rear-facing open position in response to receipt of the operator input to close the first movable side panel while the signal indicates that the temperature of the engine of the off-road vehicle is greater than the desired engine temperature range during operation of the engine, thereby blocking debris and facilitating air flow under the engine hood, and wherein a rearward portion of the first movable side panel is positioned a first distance laterally outward from the first lateral side surface of the body of the engine hood and a forward portion of the first movable side panel is positioned a second distance, less than the first distance, laterally outward from the first lateral side surface of the body of the engine hood when the first movable side panel is in the rear-facing open position.
