2018 LINCOLN MKZ HYBRID service

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 pull off the road. You cancontinue to drive your vehicle.
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. 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. If thetemperature does not drop after severalminutes, 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.
AUTOMATIC TRANSMISSION
FLUID CHECK
Note:Transmission fluid should be checkedby an authorized dealer. If required, fluidshould be added by an authorized dealer.
Have an authorized dealer check and changethe transmission fluid at the correct serviceinterval. See Maintenance (page 300). Yourtransmission does not consume fluid.However, the fluid level should be checkedif the transmission is not working properly,(i.e., if the transmission slips or shifts slowly)or if you notice some sign of fluid leakage.
Do not use supplemental transmission fluidadditives, treatments or cleaning agents. Theuse of these materials may affecttransmission operation and result in damageto internal transmission components.
BRAKE FLUID CHECK
WARNINGS
Do not use any fluid other than therecommended brake fluid as this willreduce brake efficiency. Use of incorrect fluidcould result in the loss of vehicle control,serious personal injury or death.

4.On the wall or screen you will observe aflat zone of high intensity light located atthe top of the right hand portion of thebeam pattern. If the top edge of the highintensity light zone is not at the horizontalreference line, the headlamp will needto be adjusted.
5. Locate the vertical adjuster on eachheadlamp. Using a Phillips #2screwdriver, turn the adjuster eitherclockwise or counterclockwise in orderto adjust the vertical aim of theheadlamp. The horizontal edge of thebrighter light should touch the horizontalreference line.
6. Close the hood and turn off the lamps.
Horizontal Aim Adjustment
The horizontal aim does not require anyadjustment for this vehicle. If a fault occurs,have the system checked by an authorizeddealer.
CHANGING A BULB
Lamp Assembly Condensation
Exterior lamps are vented to accommodatenormal changes in pressure. Condensationcan be a natural by-product of this design.When moist air enters the lamp assemblythrough the vents, there is a possibility thatcondensation can occur when thetemperature is cold. When normalcondensation occurs, a thin film of mist canform on the interior of the lens. The thin misteventually clears and exits through the ventsduring normal operation. Clearing time maytake as long as 48 hours under dry weatherconditions.
Examples of acceptable condensation are:
•Presence of thin mist (no streaks, dripmarks or droplets).
•Fine mist covers less than 50% of thelens.
Examples of unacceptable moisture (usuallycaused by a lamp water leak) are:
•Water puddle inside the lamp.
•Large water droplets, drip marks orstreaks present on the interior of the lens.
Take your vehicle to a dealer for service ifany of the above conditions of unacceptablemoisture are present.
Replacing Bulbs
For replacing bulbs, see your authorizeddealer.

These Tire Quality Grades aredetermined by standards that the UnitedStates Department of Transportation hasset.
Tire Quality Grades apply to newpneumatic passenger car tires. They donot apply to deep tread, winter-typesnow tires, space-saver or temporaryuse spare tires, light truck or LT typetires, tires with nominal rim diameters of10 to 12 inches or limited production tiresas defined in Title 49 Code of FederalRegulations Part 575.104 ©)(2).
U.S. Department of Transportation Tirequality grades: The U.S. Department ofTransportation requires Lincoln MotorCompany to give you the followinginformation about tire grades exactly as
the government has written it.
Treadwear
The treadwear grade is a comparativerating based on the wear rate of the tirewhen tested under controlled conditionson a specified government test course.For example, a tire graded 150 wouldwear one and one-half (1 ½) times as wellon the government course as a tiregraded 100. The relative performanceof tires depends upon the actualconditions of their use, however, andmay depart significantly from the normdue to variations in driving habits,service practices, and differences inroad characteristics and climate.
Traction AA A B C
WARNING
The traction grade assigned to thistire is based on straight-aheadbraking traction tests, and does notinclude acceleration, cornering,hydroplaning or peak tractioncharacteristics.
The traction grades, from highest tolowest are AA, A, B, and C. The gradesrepresent the tire’s ability to stop on wetpavement as measured under controlledconditions on specified government testsurfaces of asphalt and concrete. A tiremarked C may have poor tractionperformance.
Temperature A B C
WARNING
The temperature grade for this tireis established for a tire that isproperly inflated and not overloaded.Excessive speed, underinflation, orexcessive loading, either separately orin combination, can cause heat buildupand possible tire failure.
The temperature grades are A, thehighest, B and C, representing the tire’sresistance to the generation of heat andits ability to dissipate heat when testedunder controlled conditions on aspecified indoor laboratory test wheel.Sustained high temperature can cause

Location of the Tire Label
You will find a Tire Label containing tireinflation pressure by tire size and otherimportant information located on theB-Pillar or the edge of the driver’s door.
Inflating Your Tires
Safe operation of your vehicle requiresthat your tires are properly inflated.Remember that a tire can lose up to halfof its air pressure without appearing flat.
Every day before you drive, check yourtires. If one looks lower than the others,use a tire gauge to check pressure of alltires and adjust if required.
At least once a month and before longtrips, inspect each tire and check the tirepressure with a tire gauge, includingspare, if equipped. Inflate all tires to theinflation pressure recommended byLincoln Motor Company.

You are strongly urged to buy a reliabletire pressure gauge, as automaticservice station gauges may beinaccurate. Lincoln recommends the useof a digital or dial-type tire pressuregauge rather than a stick-type tirepressure gauge.
Use the recommended cold inflationpressure for optimum tire performanceand wear. Under-inflation orover-inflation may cause uneventreadwear patterns.
WARNING
Under-inflation is the most commoncause of tire failures and may resultin severe tire cracking, tread separationor blowout, with unexpected loss ofvehicle control and increased risk of
injury. Under-inflation increases sidewallflexing and rolling resistance, resultingin heat buildup and internal damage tothe tire. It also may result in unnecessarytire stress, irregular wear, loss of vehiclecontrol and accidents. A tire can lose upto half of its air pressure and not appearto be flat!
Always inflate your tires to the Lincolnrecommended inflation pressure evenif it is less than the maximum inflationpressure information found on the tire.The Lincoln recommended tire inflationpressure is found on the SafetyCompliance Certification Label, affixedto either the door hinge pillar, door-latchpost, or the door edge that meets thedoor-latch post, next to the driver'sseating position, or Tire Label which islocated on the B-Pillar or the edge of thedriver’s door. Failure to follow the tirepressure recommendations can causeuneven treadwear patterns andadversely affect the way your vehiclehandles.
Maximum Permissible InflationPressure is the tire manufacturer's
maximum permissible pressure and thepressure at which the maximum loadcan be carried by the tire. This pressureis normally higher than themanufacturer’s recommended coldinflation pressure which can be foundon the Safety Compliance CertificationLabel, affixed to either the door hinge
pillar, door-latch post, or the door edgethat meets the door-latch post, next tothe driver's seating position, or TireLabel which is located on the B-Pillar orthe edge of the driver’s door. The coldinflation pressure should never be setlower than the recommended pressureon the Safety Compliance CertificationLabel or Tire Label.
When weather temperature changesoccur, tire inflation pressures alsochange. A 10°F (6°C) temperature dropcan cause a corresponding drop of 1 psi(7 kPa) in inflation pressure. Check yourtire pressures frequently and adjustthem to the proper pressure which canbe found on the Safety ComplianceCertification Label or Tire Label.
To check the pressure in your tires:
1. Make sure the tires are cool,meaning they are not hot fromdriving even a mile.
