SEGUNDO CASO

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

E151263

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.

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.

E144692

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. 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.

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 (page 86).

Note:Frequent destinations are learned by

your vehicle after two to four weeks of use. You can clear these destinations with a Driving History reset through the Settings menu.

Note:The EV+ feature can be turned on or

off through the Driver Assist section of the Settings menu.

Frequently asked questions

Answer Question

The high voltage battery is electrically isol- ated 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. What are the series of clicks from the cargo

area when I first turn the key in the ignition?

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 the engine sometimes start at

key-on?

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 emis-

sions. As the climate gets cooler, this engine-on time is extended. Why does it take a long time before the

engine shuts down?

The engine is required to turn on above this speed to protect the transmission hard-

ware. Why does my engine never shut down

above 85 mph (137 km/h)

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 main-

tain the correct coolant temperature. Why does my engine stay on when it is

extremely cold outside?

Answer Question

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 character- istics of the Atkinson engine cycle and the

transmission technology that help maximize your hybrid's fuel economy. Why does my engine rev up so high some-

times when I accelerate?

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. What is the fan noise I hear from the rear

of my hybrid?

Change the engine oil every 10000 miles (16000 km) or once per year under normal

operating conditions. What is the engine oil change service

interval?

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). Can I put E15 or E85 in my vehicle, and how

will it affect my fuel economy?

The high voltage battery system is designed to last the life of the vehicle and requires

no maintenance. How long will my high voltage battery last?

Does it need maintenance?

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 you charge the battery with a plug into

an A/C outlet?

Yes. Your hybrid vehicle can be flat towed without modification. See Towing (page

213). Can I tow the hybrid behind my motor home

with all four wheels down?
