2018 LINCOLN MKX Owners Manual

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 coolant inorder to reach a vehicle service location. Inthis 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 of thecoolant.
Recycled Coolant
We do not recommend the use of recycledcoolant as an approved recycling process isnot yet available.
Dispose of used engine coolant in anappropriate manner. Follow yourcommunity's regulations and standards forrecycling and disposing of automotive fluids.
Severe Climates
If you drive in extremely cold climates:
•It may be necessary to increase thecoolant concentration above 50%.
•A coolant concentration of 60% providesimproved freeze point protection. Coolant concentrations above 60%decrease the overheat protectioncharacteristics of the coolant and maycause engine damage.
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 the coolantand may cause engine damage.
Vehicles driven year-round in non-extremeclimates should use prediluted coolant foroptimum cooling system and engineprotection.

Maintenance

Coolant Change
At specific mileage intervals, as listed in thescheduled maintenance information, thecoolant should be changed. Add predilutedcoolant approved to the correct specification.See Capacities and Specifications (page381).
Fail-Safe Cooling
Fail-safe cooling allows you to temporarilydrive your vehicle before any incrementalcomponent damage occurs. The fail-safedistance depends on ambient temperature,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 and amessage may appear in theinformation display.
If the engine reaches a presetover-temperature condition, the engineautomatically switches to alternating cylinderoperation. Each disabled cylinder acts as anair pump and cools the engine.
When this occurs, your vehicle still operates,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, you canre-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 long asnecessary to bring your vehicle to rest in asafe location and seek immediate repairs.When in fail-safe mode, your vehicle will havelimited power, will not be able to maintainhigh-speed operation, and may completelyshut down without warning, potentially losingengine power, power steering assist, andpower brake assist, which may increase thepossibility of a crash resulting in seriousinjury.
Never remove the coolant reservoircap when the engine is running or hot.
Your vehicle has limited engine power whenin the fail-safe mode, drive your vehicle withcaution. Your vehicle does not maintainhigh-speed operation and the engine mayoperate poorly.
Remember that the engine is capable ofautomatically shutting down to preventengine damage. In this situation:

Maintenance

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 recommend thatyou contact your roadside assistanceservice provider.
3.If this is not possible, wait a short periodfor 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, youcan re-start the engine. Have your vehiclechecked as soon as possible to minimizeengine 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 not be ableto accelerate with full power until the coolanttemperature reduces.
If you tow a trailer with your vehicle, theengine may temporarily reach a highertemperature during severe operatingconditions, for example ascending a long orsteep grade in high ambient temperatures.
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 vehicle speedcaused by reduced engine power in orderto manage the engine coolant temperature. Your vehicle may enter this mode if certainhigh-temperature and high-load conditionstake place. The amount of speed reductiondepends on vehicle loading, grade andambient temperature. If this occurs, there isno need to stop your vehicle. You cancontinue to drive.
The air conditioning may automatically turnon and off during severe operatingconditions to protect the engine fromoverheating. When the coolant temperaturedecreases to the normal operatingtemperature, the air conditioning turns on.
If the coolant temperature gauge moves fullyinto the red zone, or if the coolanttemperature warning or service engine soonmessages appear in your information display,do the following:
1.Stop your vehicle as soon as it is safe todo so. Fully apply the parking brake, shiftinto park (P) or neutral (N).

2. Leave the engine running until thecoolant temperature gauge needlereturns to the normal position. Afterseveral minutes, if the temperature doesnot drop, follow the remaining steps.
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, restart theengine and continue.

Maintenance

Note:If your vehicle has a battery cover,after cleaning or replacing the battery, makesure you reinstall it.
Note:See an authorized dealer for batteryaccess, testing, or replacement.
To make sure the battery managementsystem works correctly, do not connect anelectrical device ground connection directlyto the battery negative post. This can causeinaccurate measurements of the batterycondition and potential incorrect systemoperation.
Note:If you add electrical accessories orcomponents to the vehicle, it may adverselyaffect battery performance and durability.This may also affect the performance ofother electrical systems in the vehicle.
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.
Because your vehicle’s engine iselectronically-controlled by a computer,some engine control settings are maintainedby power from the battery. Some enginecomputer settings, like the idle trim and fueltrim strategy, optimize the driveability andperformance of the engine. The clock andradio station presets are also maintained inmemory by power from the low-voltagebattery. These settings are erased when atechnician disconnects and connects thelow-voltage battery.
To restore the settings, do the following:
Note:Until you switch the ignition to the onposition, you will receive a message in yourinformation display stating that your vehicleis not in park.
1. Apply the parking brake.
2. Shift into park (P) or neutral (N).
3. Switch off all accessories.
4. Press the brake pedal and start yourvehicle.
5. Run the engine until it reaches normaloperating temperature. While the engineis warming up, complete the following:Reset the clock. See Audio Unit (page402). Reset the power windowsbounce-back feature. See PowerWindows (page 104). Reset the radiostation presets. See Audio Unit (page402).
6. Allow the engine to idle for at least oneminute.
7.Drive the vehicle at least 10 mi (16 km) tocompletely relearn the idle trim 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 fuel trimstrategy.
Note:Certain features may not operate ifthe battery monitor system is not reset witha scan tool following a jump start or batteryreplacement. Normal electrical accessoryoperation should resume after your vehicleis left undisturbed for 8 hours.
