Abstract
A vehicle includes an engine, a transmission associated with the engine, and an engine retarder having a deactivated state and an activated state. The engine retarder is configured to provide a retarding torque to the engine in the activated state. The vehicle also includes a fan associated with the engine. The fan is configured to be activated in response to a selection of a transmission gear ratio greater than or equal to a threshold gear ratio while the engine retarder is in the activated state. The fan assists in providing additional retarding torque to the engine while activated.
