2019 LINCOLN MKT width

Why is the feature not available (line markings are gray) when I can see the lane markings on the road?
Your vehicle stays too close to the lane markings.
Driving at high speeds in curves.
The last alert warning or aid intervention occurred a short time ago.
Ambiguous lane markings, for example in construction zones.
Rapid transition from light to dark, or from dark to light.
Sudden offset in lane markings.
ABS or AdvanceTrac™ is active.
There is a camera blockage due to dirt, grime, fog, frost or water on the windshield.
You are driving too close to the vehicle in front of you.
Transitioning between no lane markings to lane markings or vice versa.
There is standing water on the road.

Tire Quality Grades apply to newpneumatic passenger car tires. TheQuality grades can be found whereapplicable on the tire sidewall betweentread shoulder and maximum sectionwidth. For example: Treadwear 200Traction AA Temperature A.
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 tires
as defined in Title 49 Code of FederalRegulations Part 575.104 (c)(2).
U.S. Department of Transportation Tirequality grades: The U.S. Department ofTransportation requires Ford MotorCompany to give you the followinginformation about tire grades exactly asthe 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 1½ times as well on thegovernment course as a tire graded 100.The relative performance of tiresdepends upon the actual conditions oftheir use, however, and may departsignificantly from the norm due tovariations in driving habits, servicepractices, and differences in roadcharacteristics and climate.
Traction AA A B C
WARNING: The traction gradeassigned to this tire is based onstraight-ahead braking traction tests,and does not include acceleration,cornering, hydroplaning or peaktraction characteristics.
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 temperaturegrade for this tire is established for atire that is properly inflated and notoverloaded. Excessive speed,underinflation, or excessive loading,either separately or in combination,can cause heat buildup and possibletire 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

Information Contained on the TireSidewall
Both United States and Canada Federalregulations require tire manufacturersto place standardized information on thesidewall of all tires. This informationidentifies and describes the fundamentalcharacteristics of the tire and alsoprovides a U.S. DOT Tire IdentificationNumber for safety standard certificationand in case of a recall.
Information on P Type Tires
P215/65R15 95H is an example of a tiresize, load index and speed rating. Thedefinitions of these items are listedbelow. (Note that the tire size, load indexand speed rating for your vehicle maybe different from this example.)
A. P: Indicates a tire, designated by theTire and Rim Association, that may beused for service on cars, sport utilityvehicles, minivans and light trucks. Note:If your tire size does not begin with aletter this may mean it is designated byeither the European Tire and RimTechnical Organization or the Japan TireManufacturing Association.
B. 215: Indicates the nominal width ofthe tire in millimeters from sidewall edgeto sidewall edge. In general, the largerthe number, the wider the tire.
C. 65: Indicates the aspect ratio whichgives the tire's ratio of height to width.
D. R: Indicates a radial type tire.
E. 15: Indicates the wheel or rim
diameter in inches. If you change yourwheel size, you will have to purchasenew tires to match the new wheeldiameter.

T type tires have some additionalinformation beyond those of P type tires;these differences are described below:
A. T: Indicates a type of tire, designatedby the Tire and Rim Association, that isintended for temporary service on cars,sport utility vehicles, minivans and lighttrucks.
B. 145: Indicates the nominal width ofthe tire in millimeters from sidewall edgeto sidewall edge. In general, the largerthe number, the wider the tire.
C. 80: Indicates the aspect ratio whichgives the tire's ratio of height to width.Numbers of 70 or lower indicate a shortsidewall.
D. D: Indicates a diagonal type tire.
R: Indicates a radial type tire.
E. 16: Indicates the wheel or rimdiameter in inches. If you change your
wheel size, you will have to purchasenew tires to match the new wheeldiameter.
Recommended Tire Pressures andInflating 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 the pressureof all tires 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 by FordMotor Company.
WARNING: Under-inflation is themost common cause of tire failuresand may result in severe tire cracking,tread separation or blowout, withunexpected loss of vehicle control andincreased risk of injury. Under-inflationincreases sidewall flexing and rolling
resistance, resulting in heat buildup
