Unique Driving Characteristics • Very high or low outside temperature (to provide system cooling or heating) For Fusion Energi vehicles, climate control demands by passengers may not directly cause the engine to run. This only occurs when the high voltage battery charge is low, or if the outside temperature is cold enough to require the engine to provide additional heat for the cabin. Engine not warm enough to provide passenger requested cabin temperature. Unique Hybrid Operating Characteristics Your vehicle behaves differently compared to a non-hybrid. Here is a description of the major differences: Battery: Your hybrid is equipped with a high voltage battery. A cool battery ensures battery life and provides the best possible performance. Your hybrid high voltage battery may periodically re-condition itself to ensure maximum efficiency. You may notice slight changes in driveability during this process, but it is an important part of your hybrid's high voltage battery optimization features. The high voltage battery is cooled by cabin air pulled into the high voltage battery through vents in the rear package tray. Avoid placing objects on the package tray that could block airflow through the vents. Engine: The engine speed in your hybrid is not directly tied to your vehicle speed. Your vehicle's engine and transmission are designed to deliver the power you need at the most efficient engine speed. During heavy accelerations, your hybrid may reach high engine speeds (up to 6000 RPM). In prolonged mountainous driving, you may see the engine tachometer changing without your input. This is intentional and maintains the battery charge level. You may also notice during extended downhill driving that your engine continues to run instead of shutting off. During this engine braking, the engine stays on, but it is not using any fuel. You may also hear a slight whine or whistle when operating your vehicle. This is the normal operation of the electric generator in the hybrid system. • Stopping: The gas engine may shut off to conserve fuel as you come to a stop. Restarting the vehicle is not required. Simply step on the accelerator when you are ready to drive. Transmission Operation: Due to the technologically advanced, electronically-controlled continuously variable transaxle, you will not feel shift changes like those of a non-hybrid vehicle. Note: Since engine speed is controlled by the transmission, it may seem elevated at times. This is normal hybrid operation and helps deliver fuel efficiency and performance. Neutral: It is not recommended to idle the vehicle in position N for an extended period of time because this will discharge your high voltage battery and decrease fuel economy. The engine will not start or stop, and cannot provide power to the hybrid system in position N. Low Gear: Low gear (position L) is designed to mimic the enhanced engine braking available in non-hybrid vehicles. Low gear will produce high engine speeds to provide necessary engine braking. This is normal and will not damage your vehicle. In low gear, the gas engine will remain on more often than in position D. Reverse: In position R, vehicle speed is limited to 22 mph (35 km/h). 151 Fusion/Mondeo (CC7), enUSA
