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.
ENGINE COOLANT CHECK
WARNINGS
Do not add engine coolant when theengine is hot. Steam and scaldingliquids released from a hot coolingsystem can burn you badly. Also, you canbe burned if you spill coolant on hot engineparts.
Do not put engine coolant in thewindshield washer fluid container. Ifsprayed on the windshield, enginecoolant could make it difficult to seethrough 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 the cap is loosenedslightly.
Do not add coolant further than theMAX mark.
Engine Coolant and InverterSystem Controller Coolant
Your vehicle has two separate coolingsystems. One is for cooling the engine andone is for cooling the inverter systemcontroller that is specific to the hybridoperating system. The two systemsoperate similarly, with the inverter systemcontroller cooling system generallyoperating at a lower temperature andpressure.
Checking the Engine Coolant
When the engine is cold, check theconcentration and level of the enginecoolant at the intervals listed in thescheduled maintenance information. SeeScheduled Maintenance (page 348).
Note:Make sure that the level is betweenthe MIN and MAX marks on the enginecoolant reservoir.
Note:Coolant expands when it is hot. Thelevel may extend beyond the MAX mark.
Note:If the level is at the MIN mark, belowthe MIN mark, or empty, add coolantimmediately. See Adding Engine Coolantin this chapter.
The coolant concentration should bemaintained within 48% to 50%, whichequates to a freeze point between -30°F(-34°C) and -34°F (-37°C).
Note:For best results, coolantconcentration should be tested with arefractometer such as Robinair® Coolantand Battery Refractometer 75240. We donot recommend the use of hydrometers orcoolant test strips for measuring coolantconcentrations.
Note:Automotive fluids are notinterchangeable. Do not use engine coolantor antifreeze or windshield washer fluidoutside of its specified function and vehiclelocation.

Maintenance

Vehicles driven year-round in non-extremeclimates should use coolant meeting theFord specification for optimum coolingsystem and engine protection.
What You Should Know About Fail-Safe Cooling
If the engine coolant supply is depleted,this feature allows the vehicle to be driventemporarily before incremental componentdamage is incurred. The “fail-safe”distance depends on ambienttemperatures, vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the enginecoolant temperature gauge will move tothe red (hot) area and:
The coolant temperaturewarning light will illuminate.
The service engine soonindicator will illuminate.
If the engine reaches a presetover-temperature condition, the enginewill automatically switch to alternatingcylinder operation. Each disabled cylinderacts as an air pump and cools the engine.
When this occurs the vehicle will stilloperate. However:
•The engine power will be limited.
•The air conditioning system will bedisabled.
Continued operation will increase theengine temperature and the engine willcompletely shut down, causing steeringand braking effort to increase.
Once the engine temperature cools, theengine can be re-started. Take your vehicleto an authorized dealer as soon as possibleto minimize engine 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 while the engine is running or hot.
Note:Driving the vehicle without repairingthe engine problem increases the chance ofengine damage. Take your vehicle to anauthorized dealer as soon as possible.
You have limited engine power when in thefail-safe mode, so drive the vehicle withcaution. The vehicle will not be able tomaintain high-speed operation and theengine will run rough. Remember that theengine is capable of completely shuttingdown automatically to prevent enginedamage, therefore:
1. Pull off the road as soon as safelypossible and turn off the engine.
2. Arrange for the vehicle to be taken toan authorized dealer.
3. If this is not possible, wait a shortperiod for the engine to cool.
4. Check the coolant level and replenishif low.
5. Re-start the engine and take yourvehicle to an authorized dealer.

AUTOMATIC TRANSMISSION
FLUID CHECK
If required, have an authorized dealer checkand change the transmission fluid at thecorrect service interval. See ScheduledMaintenance (page 348).
The automatic transmission does not havea transmission fluid dipstick. Yourtransmission does not consume fluid.
An authorized dealer should check thefluid:
•If the transmission is not workingproperly.
•If you notice signs of fluid leakage.
Do not use supplemental transmissionfluid additives, treatments or cleaningagents. The use of these materials mayaffect transmission operation and resultin damage to internal transmissioncomponents.
BRAKE FLUID CHECK
Fluid levels between the MIN and MAXlines are within the normal operating range;there is no need to add fluid. If the fluidlevels are outside of the normal operatingrange, the performance of the systemcould be compromised; seek service fromyour authorized dealer immediately.
POWER STEERING FLUID
CHECK
Your vehicle is equipped with an electricpower steering (EPS) system. There is nofluid reservoir to check or fill.
WASHER FLUID CHECK
WARNING
If you operate your vehicle intemperatures below 40°F (5°C), usewasher fluid with antifreezeprotection. Failure to use washer fluid withantifreeze protection in cold weather couldresult in impaired windshield vision andincrease the risk of injury or accident.
Note:The front and rear washer systemsare supplied from the same reservoir.
Add fluid to fill the reservoir if the level islow. Only use a washer fluid that meetsFord specifications. See Capacities andSpecifications (page 276).
State or local regulations on volatileorganic compounds may restrict the useof methanol, a common windshield washerantifreeze additive. Washer fluidscontaining non-methanol antifreezeagents should be used only if they providecold weather protection without damagingthe vehicle’s paint finish, wiper blades orwasher system.
FUEL FILTER
Your vehicle is equipped with a lifetimefuel filter that is integrated with the fueltank. Regular maintenance or replacementis not needed.

CHANGING THE 12V BATTERY
WARNINGS
Batteries normally produce explosivegases which can cause personalinjury. Therefore, do not allowflames, sparks or lighted substances tocome near the battery. When working nearthe battery, always shield your face andprotect your eyes. Always provide correctventilation.
When lifting a plastic-cased battery,excessive pressure on the end wallscould cause acid to flow through thevent caps, resulting in personal injury anddamage to the vehicle or battery. Lift thebattery with a battery carrier or with yourhands on opposite corners.
Keep batteries out of reach ofchildren. Batteries contain sulfuricacid. Avoid contact with skin, eyes orclothing. Shield your eyes when workingnear the battery to protect against possiblesplashing of acid solution. In case of acidcontact with skin or eyes, flushimmediately with water for a minimum of15 minutes and get prompt medicalattention. If acid is swallowed, call aphysician immediately.
Battery posts, terminals and relatedaccessories contain lead and leadcompounds. Wash hands afterhandling.
Your vehicle has a Motorcraft®maintenance-free battery which normallydoes not require additional water duringits life of service.
Note:If your vehicle's battery has a coveror shield, make sure it is reinstalled after thebattery has been cleaned or replaced.
Note:See an authorized dealer for lowvoltage battery access, testing, orreplacement.
When a low voltage battery replacementis necessary, see an authorized dealer toreplace the low voltage battery with a Fordrecommended replacement low voltagebattery that matches the electricalrequirements of the vehicle.
To ensure proper operation of the batterymanagement system (BMS), do not allowa technician to connect any electricaldevice ground connection directly to thelow voltage battery negative post. Aconnection at the low voltage batterynegative post can cause inaccuratemeasurements of the battery conditionand potential incorrect system operation.
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 station
