Hybrid Vehicle Operation (Fusion Hybrid and Fusion Energi)
This hybrid vehicle combines electric and gasoline propulsion to provide breakthrough performance and improved efficiency. Familiarizing yourself with these unique characteristics will provide an optimal driving experience from your new vehicle.
Note:  You may notice higher engine speeds upon start-up. This temporary condition is normal and necessary to heat up the cabin and minimize emissions.
Missing Image  Starting: When you start your vehicle, a green ready indicator light will appear in the lower right portion of the instrument cluster and a ready to drive message will appear in the middle of the left cluster screen, letting you know that the vehicle is ready for driving.
The engine may not start because this vehicle is equipped with silent key start. This fuel saving feature allows your vehicle to be ready–to–drive without requiring the gas engine to be running. This indicator will remain on while the vehicle is on, whether the engine is running or not to indicate the vehicle is capable of movement (using its electric motor, engine, or both). Typically, the engine will not start unless the vehicle is cold, a climate control change is requested, or the accelerator is pressed.
Driving: The gas engine automatically starts and stops to provide power when needed and to save fuel when not needed. While coasting at low speeds, coming to a stop, or standing, the gas engine normally shuts down and the vehicle operates in electric-only mode.
Conditions that may cause the engine to start up or remain running include:
  • Considerable vehicle acceleration.
  • Vehicle speed above 85 mph (137 km/h). However, the maximum speed for electric–only operation may be lower while driving in hot temperatures or on hilly terrain.
  • Ascending a hill.
  • Charge level of high voltage battery is low.
  • 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.
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).
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.
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.
During certain events (such as vehicle servicing) your low voltage 12-volt battery may become disconnected or disabled. Once the battery is reconnected and after driving the vehicle, the engine may continue to operate for three to five seconds after the key is turned to off. This is a normal condition.
Braking: Your hybrid is equipped with standard hydraulic braking and regenerative braking. Regenerative braking is performed by your transmission and it captures brake energy and stores it in your high voltage battery.
Driving to Optimize Fuel Economy
Note:  Having your engine running is not always an indication of inefficiency. In some cases, it is actually more efficient than driving in electric mode.
Your fuel economy should improve throughout your hybrid's break-in period. As with any vehicle, your driving habits and accessory usage can significantly impact your fuel economy. For best results, keep in mind these tips:
  • Keep the tires properly inflated and only use the recommended size.
  • Aggressive driving increases the amount of energy required to move your vehicle. In general, you can achieve better fuel economy with mild to moderate acceleration and deceleration. Moderate braking is particularly important since it allows you to maximize the energy captured by the regenerative braking system.
Additional Tips:
  • Do not carry extra loads.
  • Be mindful of adding external accessories that may increase aerodynamic drag.
  • Observe posted speed limits.
  • Perform all scheduled maintenance.
  • There is no need to wait for your engine to warm up. The vehicle is ready to drive immediately after starting.
EV+ Mode
Your vehicle will recognize your frequent destinations and allow for more EV driving as you approach them. For example, when nearing your home it should be easier to stay in electric mode. The EV indicator will display EV+ when this mode is active. You should see this about 1/8 mile (200 meters) from a frequent destination. See Information Displays
Note:  Frequent destinations are learned by your vehicle after two to four weeks of use. To add a destination immediately, perform the following process: cycle the ignition on for 2 seconds, but do not start your vehicle, then off for 2 seconds. Repeat the process 10 times. This location is now programmed for EV+. You can clear these destinations with a Driving History reset through the Settings menu.
Note:  You can switch the EV+ feature on or off through the Driver Assist section of the Settings menu.
Plug-in Power Mode and Hybrid Mode (Fusion Energi Only)
You must plug in your Fusion Energi vehicle regularly for optimal use of the high voltage battery's extended range capability. When you charge your vehicle, you add electrical energy that is then used to propel the vehicle in plug-in power mode. You can view your estimated electric range on the Energy Use screen on the left-hand information display. You can also configure MyView to include detailed vehicle range information. See Information Displays.  The system maximizes the use of electric-only operation in plug-in power mode. System conditions may require engine operation; however, the system uses plug-in power whenever possible.
When your plug-in power has been depleted, the powertrain system will automatically switch to hybrid mode. Your battery gauge will transition to a simple battery graphic upon entering hybrid mode. Hybrid mode uses both the gasoline engine and electric motor to power your vehicle and maximize fuel economy as with Fusion Hybrid.
EV Modes
Missing Image  Your plug-in hybrid vehicle contains selectable EV modes through the EV button on the center console.
These modes are available when the vehicle can run under high voltage battery power. With the vehicle in driving mode, you can change EV modes with each press of the EV button. The current mode displays in the left hand instrument cluster screen.
Auto EV
Missing Image  This mode provides an automatic use of high-voltage battery power during the drive, staying in electric mode when possible and running the engine when needed. This mode will be the only one available if the plug-in power has been depleted.
EV Now
Missing Image  This mode provides an electric only driving experience using plug-in power. The left-hand information display will change to an Energy Use screen that supplies EV specific tools and functions. The vehicle may accelerate more slowly and the top speed may be lower than in Auto mode. Your engine may be enabled at any time by using one of the following methods:
  1. Press the OK button on the left 5–way steering wheel control while viewing the Energy Use screen. The vehicle will enable the engine as needed, and will automatically return to EV Now after eight seconds or when the engine is no longer needed.
  1. Press the accelerator pedal fully. A pop up message stating Press OK to Enable Engine will appear. Press OK on the left steering wheel button to activate as needed. The message will disappear if you release the accelerator pedal.
  1. Press the EV button. This will change the mode to EV Later and permit engine operation.
The vehicle may automatically enter Engine Enabled mode if system conditions require it. A message Engine Enabled for System Performance will display if this occurs. This is normal function, and your vehicle will return to EV Now when possible.
The vehicle may enter Enable Engine mode if the climate control is in a defrost mode and the outside temperature is cold. A message Engine Enabled Due to Defrost will display if this occurs. If defrost is not needed, select a different climate control mode to permit EV Now.
When you enable EV Now, a blue EV icon displays in the left-hand information display. If the vehicle is in the Engine Enabled mode, the EV icon will be yellow.
EV Now will automatically exit when the Plug in power has been depleted.
EV Later
Missing Image  This mode saves most of the high voltage battery plug in power for future use (for example, your initial drive is at high speeds on open roads, but later your drive will be at low speeds in an urban area where plug-in power usage is most efficient). Your vehicle will run the engine as needed and keep most of the high voltage battery plug in power for later use in Auto Mode or EV Now mode.
When you enable EV Later, a white EV Later icon appears on the left-hand information display.
The EV Later mode will automatically reset to EV Auto mode when you power the vehicle off. You may press the EV button twice during the next drive to return to EV Later mode, if desired.
ECO Cruise
Note:  ECO Cruise is available as a separate system on Fusion Energi only. On Fusion Hybrid it is included in EcoSelect.
The system saves vehicle energy by relaxing acceleration, compared to standard cruise control which only maintains speed. For example your vehicle may temporarily lose speed when going uphill. When set on, ECO will appear in the information display when cruise control is switched on. You can switch this on or off in the settings menu.
Low Engine Use
The low engine use mode is equipped on Fusion Energi models only. The low engine use mode will activate automatically when you drive your vehicle with limited engine use. The mode will maintain proper engine lubrication at sufficient temperature. If your vehicle is in low engine use mode when you start the vehicle, a message will appear in the information display. When your vehicle is in low engine use mode, your vehicle will automatically run the engine as necessary. If you select the EV Now mode while the vehicle is in the low engine use mode, EV Now mode will be suspended for as long as you are in low engine use mode. The low engine use mode will resume the next time you start your vehicle and will automatically stop when no longer needed.
Note:  Cold temperatures will affect the engine warm up time and the low engine use mode may operate more frequently.
Note:  An oil change is not required but gives you the option of not running a low engine use cycle. Resetting the oil life monitoring system will suspend the low engine use mode.
Fuel Freshness Mode
See  Fuel Quality
EcoSelect (Fusion Hybrid Only)
EcoSelect is a drive mode for non-plugin vehicles designed to offer the best possible fuel economy with only a slight impact to vehicle performance and comfort.
Missing Image  To activate EcoSelect, press the ECO button on the center console.
A graphic displays on your information display when EcoSelect is active.
Your vehicle will remember the last selected mode between key cycles.
EcoSelect allows your vehicle to operate more efficiently. You will notice:
  • Less aggressive heating and cooling.
  • Softer acceleration.
  • More regenerative braking.
  • Changes in engine behavior.
  • ECO Cruise control activation.
Frequently Asked Questions

Question  Answer 
What are the series of clicks from the cargo area when I first turn the key in the ignition?  The high voltage battery is electrically isolated from the rest of the vehicle when the key is off. When you turn the key to on, high voltage contactors inside the battery are closed to make the electricity available to the motor/generator and enable the vehicle to drive. The clicks are the sound of these contactors as they close and open during start up and shut down. 
Why does the engine sometimes start at key-on?  The vehicle's computer will determine if an engine start is required at key-on. Silent key start will start the engine if it is necessary for cabin heating, windshield defrost, or if the outside temperature is low. (For Fusion Energi vehicles, the engine may not be required to operate these functions.) 
Why does it take a long time before the engine shuts down?  There are several reasons the engine stays on for an extended amount of time when you first start it. One common reason is to ensure that the emissions components are warm enough to minimize tailpipe emissions. As the climate gets cooler, this engine-on time is extended. 
Why does my engine never shut down above 85 mph (137 km/h)   The engine is required to turn on above this speed to protect the transmission hardware.  
Why does my engine stay on when it is extremely cold outside?  In order to ensure that the climate control system can begin heating the cabin or defrosting the windshield as soon as a driver requests it, the engine coolant temperature has to be kept sufficiently hot. Keeping the engine on is required to maintain the correct coolant temperature.  
Why does my engine rev up so high sometimes when I accelerate?  Your vehicle's engine and transmission are designed to deliver the power you need at the most efficient engine speed. This may be higher than expected during heavy accelerations, and may fluctuate during steady state driving. These are characteristics of the Atkinson engine cycle and the transmission technology that help maximize your hybrid's fuel economy. 
What is the fan noise I hear from the rear of my hybrid?   The fan noise comes from a fan located outside the high voltage battery. This fan turns on when the battery requires cooling air. The fan speed, and associated noise level, will change according to the amount of cooling required to maintain good performance. Maintaining the battery temperature at optimal conditions also prolongs the useful life of the battery and helps to achieve better fuel economy. Do not place objects on the package tray which could block air flow through the hybrid vehicle battery cooling vents. 
What is the engine oil change service interval?  Change the engine oil every 10000 miles (16000 km) or once per year under normal operating conditions.  
Can I put E15 or E85 in my vehicle, and how will it affect my fuel economy?  Your hybrid vehicle can use E15 (15% ethanol, 85% gasoline) fuel, but you may notice slightly reduced fuel economy because ethanol contains less energy per gallon than gasoline. Your hybrid vehicle is not designed to use E85 (85% ethanol). 
How long will my high voltage battery last? Does it need maintenance?  The high voltage battery system is designed to last the life of the vehicle and requires no maintenance. 
Can you charge the battery with a plug into an A/C outlet?  There are no provisions for charging the high voltage battery from a power supply external to the vehicle. (For Fusion Energi vehicles, the vehicle can be plugged into a 110-volt outlet with charge cord provided.) 
Can I tow the hybrid behind my motor home with all four wheels down?  Yes. Your hybrid vehicle can be flat towed without modification. See  Towing a Trailer.
