Keep your hands and clothing clearof the engine cooling fan.
2162018 Focus (CDH) Canada/United States of America, JM5J 19A321 AA enUSA, Edition date: 201706, Second PrintingMaintenanceE142732

Under certain conditions, the enginecooling fan may continue to run for severalminutes after you switch your vehicle off.
ENGINE COOLANT CHECK
WARNINGS
Never remove the coolant reservoircap when the engine is running orhot.
Do not put coolant in the windshieldwasher reservoir. If sprayed on thewindshield, coolant could make itdifficult 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.
When the engine is cold, check theconcentration and level of the coolant atthe intervals listed in the scheduledmaintenance information. See ScheduledMaintenance (page 409).
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 -29°F (-34°C) and -35°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
WARNINGS
Do not add engine coolant when theengine is hot. Failure to follow thisinstruction could result in personalinjury.
Never remove the coolant reservoircap when the engine is running orhot.
Note: Automotive fluids are notinterchangeable. Take care not to putengine coolant in the windshield washerfluid reservoir or windshield washer fluid inthe engine coolant reservoir.
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 268). 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.
Note:If prediluted coolant is not available,use the approved concentrated coolantdiluting it to 50/50 with distilled water. SeeCapacities and Specifications (page 268).Using water that has not been deionisedmay contribute to deposit formation,corrosion and plugging of the small coolingsystem passageways.
2172018 Focus (CDH) Canada/United States of America, JM5J 19A321 AA enUSA, Edition date: 201706, Second PrintingMaintenance

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 (page268).
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.
In case of emergency, you can add a largeamount of water without engine coolantin order to reach a vehicle service location.In this instance, qualified personnel:
1.Must drain the cooling system.
2.Chemically clean the coolant system.
3.Refill with engine coolant as soon aspossible.
Water alone, without engine coolant, cancause engine damage from corrosion,overheating or freezing.
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.
2182018 Focus (CDH) Canada/United States of America, JM5J 19A321 AA enUSA, Edition date: 201706, Second PrintingMaintenance

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 268).
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,the coolant temperature gaugemoves toward the 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.
2192018 Focus (CDH) Canada/United States of America, JM5J 19A321 AA enUSA, Edition date: 201706, Second PrintingMaintenance

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 inorder 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 noneed to stop your vehicle. You cancontinue to drive.
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.Stop your vehicle as soon as it is safeto do so. Fully apply the parking brake,shift into park (P) or neutral (N).
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.

FLUID CHECK
The automatic transmission does not havea transmission fluid dipstick.
Have an authorized dealer check andchange the transmission fluid at thecorrect service interval. See ScheduledMaintenance (page 409). Yourtransmission does not consume fluid.However, if the transmission slips, shiftsslowly or if you notice a sign of leakingfluid, contact an authorized dealer.
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
WARNINGS
Do not use any fluid other than therecommended brake fluid as this willreduce brake efficiency. Use ofincorrect fluid could result in the loss ofvehicle control, serious personal injury ordeath.
Only use brake fluid from a sealedcontainer. Contamination with dirt,water, petroleum products or othermaterials may result in brake systemdamage or failure. Failure to adhere to thiswarning could result in the loss of vehiclecontrol, serious personal injury or death.
Do not allow the fluid to touch yourskin or eyes. If this happens, rinse theaffected areas immediately withplenty of water and contact your physician.
WARNINGS
A fluid level between the MAX andMIN lines is within the normaloperating range and there is no needto add fluid. A fluid level not in the normaloperating range could compromise theperformance of the system. Have yourvehicle checked immediately.
To avoid fluid contamination, the reservoircap must remain in place and fully tight,unless you are adding fluid.
Only use fluid that meets Fordspecifications.
CLUTCH FLUID CHECK -
MANUAL TRANSMISSION
The clutch and brake systems share thesame fluid reservoir. See Brake FluidCheck (page 221).
2212018 Focus (CDH) Canada/United States of America, JM5J 19A321 AA enUSA, Edition date: 201706, Second PrintingMaintenanceE170684

WASHER FLUID CHECK
When adding fluid, use a mixture of washerfluid and water to help prevent freezingand improve the cleaning capability. Forinformation on fluid dilution follow themanufacturer's instructions.
Note:The reservoir supplies the front andrear washer systems.
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.
2222018 Focus (CDH) Canada/United States of America, JM5J 19A321 AA enUSA, Edition date: 201706, Second PrintingMaintenance

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 281). Reset the powerwindows bounce-back feature. SeeWindows and Mirrors (page 82).Reset the radio station presets. SeeAudio System (page 281).
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.
