Low Engine Use (If Equipped)
The low engine use mode is equipped onEnergi models only. The low engine usemode keeps the engine oil quality in goodcondition when you drive your vehicle withlimited engine use. If your vehicle is in lowengine use mode when you start thevehicle, a message appears in theinformation display. When your vehicle isin low engine use mode, your vehicle runsthe engine as necessary.
Selecting EV Now mode when your vehicleis in the low engine use mode suspendsthe low engine use mode for as long as youcontinue driving your vehicle. The lowengine use mode resumes the next timeyou start your vehicle.
Changing the engine oil and resetting theoil life monitoring system suspends the lowengine use mode.
Operating in Cold Climates andShort Driving Cycles
Some gasoline engines may experience abuildup of moisture in the engine oil ifrepeatedly operated in cold weather andshort driving cycles that do not fully warmthe engine.
When you see a thick milky substanceunder the oil cap, this indicates moistureis present.
This condition can be more prevalent ingas electric hybrid vehicles that run the gasengine for very short driving cycles.
To prevent engine damage under theseconditions customers should follow thesesteps:
•Drive your vehicle at full enginetemperature for 15 to 30 minutes.
•Drive your vehicle at highway speeds.
•Drive your vehicle with the defroster(hybrid vehicles) at full.
We recommend frequent oil changes.Follow severe duty cycle in themaintenance guide. This helps remove themoisture contaminated oil from the engine.
Cold Weather Operation
To determine if the shortened oil changeinterval or warming of the engine issufficient, clean and check the oil fill capon a regular basis. This will confirm thatthe thick milky substance is not returning.
When extreme cold weather and sub-zeroconditions exist, fuel may be found in theengine oil. This is caused by the engine notreaching its full engine temperature.
In this situation, carry out the above stepsto prevent engine damage.

ENGINE COOLANT CHECK
WARNINGS
To reduce the risk of personal injury,make sure the engine is cool beforeunscrewing the coolant pressurerelief cap. The cooling system is underpressure. Steam and hot liquid can comeout forcefully when you loosen the capslightly.
Do not put coolant in the windshieldwasher fluid reservoir. If sprayed onthe windshield, coolant could makeit difficult to see through the windshield.
To reduce the risk of personal injury,make sure the engine is cool beforeunscrewing the coolant pressurerelief cap. The cooling system is underpressure. Steam and hot liquid can comeout forcefully when you loosen the capslightly.
Do not add coolant further than theMAX mark.
Your vehicle has two separate coolingsystems. One for cooling the engine and aseparate system for cooling the invertersystem controller that is specific to thehybrid operating system. The two systemsoperate similarly, with the inverter systemcontroller cooling system generallyoperating at a lower temperature andpressure.
When the engine is cold, check theconcentration and level of the coolant atthe intervals listed in the scheduledmaintenance information. See ScheduledMaintenance (page 441).
Note:Make sure that the coolant level isbetween the MIN and MAX marks on thecoolant reservoir.
Note: Coolant expands when it is hot. Thelevel may extend beyond the MAX mark.
Maintain coolant concentration within48% to 50%, which equates to a freezepoint between -30°F (-34°C) and -34°F(-37°C). Coolant concentration should bechecked using a refractometer. We do notrecommend the use of hydrometers orcoolant test strips for measuring coolantconcentration.
Adding Coolant
WARNING
Never remove the coolant reservoircap 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 predilutedcoolant approved to the correctspecification in order to avoid plugging thesmall passageways in the engine coolingsystem. See Capacities andSpecifications (page 286). Do not mixdifferent colors or types of coolant in yourvehicle. Mixing of engine coolants or usingan incorrect coolant may harm the engineor cooling system components and maynot be covered by the vehicle Warranty.

Maintenance

Note:If prediluted coolant is not available,use the approved concentrated coolantdiluting it to 50/50 with distilled water. SeeCapacities and Specifications (page 282).Using water that has not been deionisedmay 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 thefollowing:
1. Unscrew the cap slowly. Any pressureescapes as you unscrew the cap.
2. Add prediluted coolant approved tothe correct specification. SeeCapacities and Specifications (page282).
3. Add enough prediluted coolant toreach the correct level.
4.Replace the coolant reservoir cap, turnit clockwise until you feel a strongresistance.
5. Check the coolant level in the coolantreservoir the next few times you driveyour vehicle. If necessary, add enoughprediluted engine coolant to bring thecoolant level to the correct level.
If you have to add more than 1.1 qt (1 L) ofengine coolant per month, have yourvehicle checked as soon as possible.Operating an engine with a low level ofcoolant can result in engine overheatingand possible engine damage.
Note:During normal vehicle operation, thecoolant may change color from orange topink or light red. As long as the coolant isclear and uncontaminated, this color changedoes not indicate the coolant has degradednor does it require the coolant to be drained,the system to be flushed, or the coolant tobe replaced.
Note:In case of emergency, you can add alarge amount of water without coolant inorder to reach a vehicle service location.Water alone, without coolant, can causeengine damage from corrosion, overheatingor freezing. When you reach a servicelocation, you must have the cooling systemdrained and refilled with prediluted coolantapproved to the correct specification. SeeCapacities and Specifications (page 282).
Do not use the following as a coolantsubstitute:
•Alcohol.
•Methanol.
•Brine.
•Any coolant mixed with alcohol ormethanol antifreeze.
Alcohol and other liquids can cause enginedamage from overheating or freezing.
Do not add extra inhibitors or additives tothe coolant. These can be harmful andcompromise the corrosion protection ofthe coolant.
Recycled Coolant
We do not recommend the use of recycledcoolant as an approved recycling processis not yet available.
Dispose of used engine coolant in anappropriate manner. Follow yourcommunity’s regulations and standardsfor recycling and disposing of automotivefluids.

Maintenance

Severe Climates
If you drive in extremely cold climates:
•It may be necessary to increase thecoolant concentration above 50%.
•A coolant concentration of 60%provides improved freeze pointprotection. Coolant concentrationsabove 60% decrease the overheatprotection characteristics of thecoolant and may cause enginedamage.
If you drive in extremely hot climates:
•You can decrease the coolantconcentration to 40%.
•Coolant concentrations below 40%decrease the freeze and corrosionprotection characteristics of thecoolant and may cause enginedamage.
Vehicles driven year-round in non-extremeclimates should use prediluted coolant foroptimum cooling system and engineprotection.
Coolant Change
At specific mileage intervals, as listed inthe scheduled maintenance information,the coolant should be changed. Addprediluted coolant approved to the correctspecification. See Capacities andSpecifications (page 282).
Fail-Safe Cooling
Fail-safe cooling allows you to temporarilydrive your vehicle before any incrementalcomponent damage occurs. The fail-safedistance depends on ambienttemperature, vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, thecoolant temperature gauge moves towardthe red zone:
A warning lamp illuminates anda message may appear in theinformation display.
If the engine reaches a presetover-temperature condition, the engineautomatically switches to alternatingcylinder operation. Each disabled cylinderacts as an air pump and cools the engine.
When this occurs, your vehicle stilloperates, however:
•Engine power is limited.
•The air conditioning system turns off.
Continued operation increases the enginetemperature, causing the engine tocompletely shut down. Your steering andbraking effort increases in this situation.
When the engine temperature cools, youcan re-start the engine. Have your vehiclechecked as soon as possible to minimizeengine damage.
When Fail-Safe Mode Is Activated
WARNINGS
Fail-safe mode is for use duringemergencies only. Operate yourvehicle in fail-safe mode only as longas necessary to bring your vehicle to restin a safe location and seek immediaterepairs. When in fail-safe mode, yourvehicle will have limited power, will not beable to maintain high-speed operation, andmay completely shut down withoutwarning, potentially losing engine power,power steering assist, and power brakeassist, which may increase the possibilityof a crash resulting in serious injury.
Never remove the coolant reservoircap when the engine is running orhot.

Maintenance

Your vehicle has limited engine powerwhen in the fail-safe mode, drive yourvehicle with caution. Your vehicle does notmaintain high-speed operation and theengine may operate poorly.
Remember that the engine is capable ofautomatically shutting down to preventengine damage. In this situation:
1. Pull off the road as soon as safelypossible and switch the engine off.
2. If you are a member of a roadsideassistance program, we recommendthat you contact your roadsideassistance service provider.
3. If this is not possible, wait a shortperiod for the engine to cool.
4. Check the coolant level. If the coolantlevel is at or below the minimum mark,add prediluted coolant immediately.
5. When the engine temperature cools,you can re-start the engine. Have yourvehicle checked as soon as possible tominimize engine damage.
Note:Driving your vehicle without repairincreases the chance of engine damage.
Engine Coolant TemperatureManagement (If Equipped)
WARNING
To reduce the risk of crash and injury,be prepared that the vehicle speedmay reduce and the vehicle may notbe able to accelerate with full power untilthe coolant temperature reduces.
If you tow a trailer with your vehicle, theengine may temporarily reach a highertemperature during severe operatingconditions, for example ascending a longor steep grade in high ambienttemperatures.
At this time, you may notice the coolanttemperature gauge moves toward the redzone and a message may appear in theinformation display.
You may notice a reduction in vehiclespeed caused by reduced engine power.In order to manage the engine coolanttemperature. Your vehicle may enter thismode if certain high-temperature andhigh-load conditions take place. Theamount of speed reduction depends onvehicle loading, grade and ambienttemperature. If this occurs, there is no needto pull off the road. You can continue todrive your vehicle.
The air conditioning may automaticallyturn on and off during severe operatingconditions to protect the engine fromoverheating. When the coolanttemperature decreases to the normaloperating temperature, the air conditioningturns on.
If the coolant temperature gauge movesfully into the red zone, or if the coolanttemperature warning or service enginesoon messages appear in your informationdisplay, do the following:
1. Pull off the road as soon as safelypossible and shift the transmission intopark (P).
2. Leave the engine running until thecoolant temperature gauge needlereturns to the normal position. Afterseveral minutes, if the temperaturedoes not drop, follow the remainingsteps.
3.Switch the engine off and wait for it tocool. Check the coolant level.
4. If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
5. If the coolant level is normal, restartthe engine and continue.

Maintenance

Note:If a person adds electrical orelectronic accessories or components to thevehicle, the accessories or components mayadversely affect the low voltage batteryperformance and durability and may alsoaffect the performance of other electricalsystems in the vehicle.
For longer, trouble-free operation, keep thetop of the battery clean and dry. Also,make certain the battery cables are alwaystightly fastened to the battery terminals.
If you see any corrosion on the battery orterminals, remove the cables from theterminals and clean with a wire brush. Youcan neutralize the acid with a solution ofbaking soda and water.
When a battery replacement is required,the battery should only be replaced witha Ford recommended replacement batterythat matches the electrical requirementsof the vehicle.
Because your vehicle’s engine iselectronically-controlled by a computer,some engine control settings aremaintained by power from the low voltagebattery. Some engine computer settings,like the idle trim and fuel trim strategy,optimize the driveability and performanceof the engine. Some other computersettings, like the clock and radio stationpresets, are also maintained in memory bypower from the low voltage battery. Whena technician disconnects and connects thelow voltage battery, these settings areerased. Complete the following procedurein order to restore the settings:
1. With the vehicle at a complete stop,set the parking brake.
2. Shift into park (P).
3. Switch off all accessories.
4. Fully press the brake pedal and startthe vehicle.
5. Run the engine until it reaches normaloperating temperature. While theengine is warming up, complete thefollowing: Reset the clock. See AudioSystem (page 289). Reset the powerwindows bounce-back feature. SeeWindows and Mirrors (page 78).Reset the radio station presets. SeeAudio System (page 289).
6.Allow the engine to idle for at least oneminute. If the engine turns off, pressthe accelerator pedal to start theengine.
7. While the engine is running, press thebrake pedal and shift into neutral (N).
8.Allow the engine to run for at least oneminute by pressing on the acceleratorpedal.
9.Drive the vehicle at least 12 mi (20 km)to completely relearn the idle and fueltrim strategy.
Note:If you do not allow the engine torelearn the idle and fuel trim strategy, theidle quality of your vehicle may be adverselyaffected until the engine computereventually relearns the idle trim and fueltrim strategy.
Make sure that you dispose of old batteriesin an environmentally friendly way. Seekadvice from your local authority aboutrecycling old batteries.
