HYBRID VEHICLE OPERATION
This hybrid vehicle combines electric andgasoline propulsion to provide breakthroughperformance and improved efficiency.
Familiarizing yourself with these uniquecharacteristics will provide an optimal drivingexperience from your new vehicle.
Note:You may notice higher engine speedsupon start-up. This temporary condition isnormal and necessary to heat up the cabinand minimize emissions.
Starting:
When you start your vehicle, agreen ready indicator light willappear in the lower right portionof the instrument cluster and a ready to drivemessage will appear in the middle of the leftcluster screen, letting you know that yourvehicle is ready for driving.
The engine may not start because thisvehicle is equipped with silent key start. Thisfuel saving feature allows your vehicle to beready–to–drive without requiring the gasengine to be running. This indicator willremain on while your vehicle is on, whetherthe engine is running or not to indicate yourvehicle is capable of movement (using itselectric motor, engine, or both). Typically, theengine will not start unless the vehicle iscold, a climate control change is requested,or the accelerator is pressed.
Driving:
The gas engine automatically starts andstops to provide power when needed andto save fuel when not needed. Whilecoasting at low speeds, coming to a stop, orstanding, the gas engine normally shutsdown and your vehicle operates inelectric-only mode.
Conditions that may cause the engine to startup or remain running include:
•Considerable vehicle acceleration.
•Vehicle speed above 85 mph (137 km/h).However, the maximum speed forelectric-only operation may be lowerwhile driving in hot temperatures or onhilly terrain.
•Ascending a hill.
•Charge level of high voltage battery islow.
•Very high or low outside temperature (toprovide system cooling or heating).
•Engine not warm enough to providepassenger requested cabin temperature.
Stopping:
The gas engine may shut off to conserve fuelas you come to a stop. Restarting yourvehicle is not required. Simply step on theaccelerator when you are ready to drive.

During certain events (such as vehicleservicing) your low voltage 12-volt batterymay become disconnected or disabled. Oncethe battery is reconnected and after drivingthe vehicle, the engine may continue tooperate for three to five seconds after thekey is turned to off. This is a normalcondition.
Braking:
Your hybrid is equipped with standardhydraulic braking and regenerative braking.Regenerative braking is performed by yourtransmission and it captures brake energyand stores it in your high voltage battery.
Driving to Optimize Fuel Economy
Note:Having your engine running is notalways an indication of inefficiency. In somecases, it is actually more efficient thandriving in electric mode.
Your fuel economy should improvethroughout your hybrid's break-in period. Aswith any vehicle, your driving habits andaccessory usage can significantly impactyour fuel economy. For best results, keep inmind these tips:
•Keep the tires properly inflated and onlyuse the recommended size.
•Aggressive driving increases the amountof energy required to move your vehicle.In general, you can achieve better fueleconomy with mild to moderateacceleration and deceleration. Moderatebraking is particularly important since itallows you to maximize the energycaptured by the regenerative brakingsystem.
Additional Tips:
•Do not carry extra loads.
•Be mindful of adding externalaccessories that may increaseaerodynamic drag.
•Observe posted speed limits.
•Perform all scheduled maintenance.
•There is no need to wait for your engineto warm up. The vehicle is ready to driveimmediately after starting.
ECOSELECT
EcoSelect is a drive mode for non plug-invehicles designed to offer the best possiblefuel economy with tradeoffs in vehicleperformance and comfort.
To switch EcoSelect on, press theECO button.
A graphic displays on your informationdisplay when EcoSelect is on.
Your vehicle will remember the last selectedmode whenever you start your vehicle.
EcoSelect allows your vehicle to operatemore efficiently. You will notice:
•Less aggressive cooling.
•Softer acceleration.
•Increased deceleration when coasting.

AnswerQuestion
In order to make sure that the climate control system can begin heatingthe cabin or defrosting the windshield as soon as a driver requestsit, the engine coolant temperature has to be kept sufficiently hot.Keeping the engine on is required to maintain the correct coolanttemperature.
Why does my engine stay on when it is extremely cold outside?
Your vehicle's engine and transmission are designed to deliver thepower you need at the most efficient engine speed. This may behigher than expected during heavy accelerations, and may fluctuatewhen driving at a steady speed. These are characteristics of theAtkinson engine cycle and the transmission technology that helpmaximize your hybrid's fuel economy.
Why does my engine rev up so high sometimes when I accelerate?
The fan noise comes from a fan located next to the high voltagebattery pack. This fan turns on when the battery requires cooling air.The fan speed, and associated noise level, will change according tothe amount of cooling required to maintain good performance. Main-taining the battery temperature at optimal conditions also prolongsthe 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 10,000 mi (16,000 km) or once per yearunder normal operating conditions.What is the engine oil change service interval?
Your hybrid vehicle can use E15 (15% ethanol, 85% gasoline) fuel, butyou may notice slightly reduced fuel economy because ethanolcontains less energy per gallon than gasoline. Your hybrid vehicle isnot designed to use E85 (85% ethanol).
Can I put E15 or E85 in my vehicle, and how will it affect my fueleconomy?

ENGINE COOLANT CHECK
WARNING: Never remove the coolantreservoir cap when the engine is running orhot.
WARNING: Do not put coolant in thewindshield washer reservoir. If sprayed onthe windshield, coolant could make it difficultto see through the windshield.
WARNING: To reduce the risk ofpersonal injury, make sure the engine is coolbefore unscrewing the coolant pressure reliefcap. The cooling system is under pressure.Steam and hot liquid can come out forcefullywhen you loosen the cap slightly.
WARNING: Do not add coolant furtherthan the MAX mark.
Your vehicle has two separate coolingsystems. One for cooling the engine and aseparate system for cooling the invertersystem controller that is specific to the hybridoperating system. The two systems operatesimilarly, with the inverter system controllercooling system generally operating at a lowertemperature and pressure.

Maintenance

When the engine is cold, check theconcentration and level of the coolant at theintervals listed in the scheduled maintenanceinformation. See Scheduled Maintenance(page 486).
Note:Make sure that the coolant level isbetween the MIN and the MAX marks onthe coolant reservoir.
Note: Coolant expands when it is hot. Thelevel may extend beyond the MAX mark.
Maintain coolant concentration within 48%to 50%, which equates to a freeze pointbetween -30°F (-34°C) and -34°F (-37°C).Coolant concentration should be checkedusing a refractometer. We do not recommendthe use of hydrometers or coolant test stripsfor measuring coolant concentration.
Adding Coolant
WARNING: Do not add engine coolantwhen the engine is hot. Failure to follow thisinstruction could result in personal injury.
WARNING: Never remove the coolantreservoir cap when the engine is running orhot.
Note: Automotive fluids are notinterchangeable. Do not use coolant orwindshield washer fluid outside of itsspecified function and vehicle location.
Note: Do not use stop leak pellets, coolingsystem sealants, or non-specified additivesas they can cause damage to the enginecooling or heating systems. Resultingcomponent damage may not be covered bythe vehicle Warranty.
It is very important to use prediluted coolantapproved to the correct specification in orderto avoid plugging the small passageways inthe engine cooling system. See Capacitiesand Specifications (page 357). Do not mixdifferent colors or types of coolant in yourvehicle. Mixing of engine coolants or usingan incorrect coolant may harm the engine orcooling system components and may not becovered by the vehicle Warranty.
Note:If prediluted coolant is not available,use the approved concentrated coolantdiluting it to 50/50 with distilled water. SeeCapacities and Specifications (page 353).Using water that has not been deionizedmay contribute to deposit formation,corrosion and plugging of the small coolingsystem passageways.
Note: Coolants marketed for all makes andmodels may not be approved to Fordspecifications and may cause damage tothe cooling system. Resulting componentdamage may not be covered by the vehicleWarranty.
If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
To top up the coolant level do the following:
1. Unscrew the cap slowly. Any pressureescapes as you unscrew the cap.
2. Add prediluted coolant approved to thecorrect specification. See Capacities andSpecifications (page 353).
3.Add enough prediluted coolant to reachthe correct level.
