2019 LINCOLN MKZ Owners Manual

Rotating your tires at the recommendedinterval (as indicated in the ScheduledMaintenance chapter) will help your tireswear more evenly, providing better tireperformance and longer tire life.
Front-wheel drive and all-wheel drivevehicles (front tires on the left side ofthe diagram)
All vehicles with directional tires (fronttires on the left of the diagram)
Sometimes irregular tire wear can becorrected by rotating the tires.
USING SUMMER TIRES
Summer tires provide superior performanceon wet and dry roads. Summer tires do nothave the Mud and Snow (M+S or M/S) tiretraction rating on the tire side wall. Sincesummer tires do not have the same tractionperformance as All-season or Snow tires, wedo not recommend using summer tires whentemperatures drop to approximately 45°F(7°C) or below (depending on tire wear andenvironmental conditions) or in snow and ice
conditions. Like any tire, summer tireperformance is affected by tire wear andenvironmental conditions. If you must drivein those conditions, we recommend usingMud and Snow (M+S, M/S), All-season orSnow tires.
Always store your summer tires indoors attemperatures above 19°F (-7°C). The rubbercompounds used in these tires lose flexibilityand may develop surface cracks in the treadarea at temperatures below 19°F (-7°C). If thetires have been subjected to 19°F (-7°C) orless, warm them in a heated space to at least41°F (5°C) for at least 24 hours beforeinstalling them on a vehicle, or moving thevehicle with the tires installed, or checkingtire inflation. Do not place tires near heatersor heating devices used to warm the roomwhere the tires are stored. Do not apply heator blow heated air directly on the tires.Always inspect the tires after storage periodsand before use.

USING SNOW CHAINS
WARNING: If you choose to installsnow tires on your vehicle, they must be thesame size, construction, and load range asthe original tires listed on the tire placard,and they must be installed on all four wheels.Mixing tires of different size or constructionon your vehicle can adversely affect yourvehicle's handling and braking, and may leadto loss of vehicle control.
WARNING: The use ofnon-recommended tires and wheels couldcause steering, suspension, axle, transfercase or power transfer unit failure. If youhave questions regarding tire replacement,contact your authorized dealer as soon aspossible.
The tires on your vehicle may haveall-weather treads to provide traction in rainand snow. However, in some climates youmay need to use snow chains.
Your vehicle may not be compatible withsnow chain or cable usage with thefactory-fitted wheels and tires. Only certainchains or snow cables have been approvedby Lincoln as safe for use on your vehiclewith the following tire size: 225/55R17. Youshould only install chains or cables sized at10 mm or less in dimension as measured onthe sidewall of your tire. Not all S-class snowchains meet these restrictions. Chains of thissize restriction will include a tensioningdevice. The chains should be mounted inpairs on the front tires only. If you need touse chains, it is recommended that steelwheels (of the same size and specification)be used, as chains may chip aluminumwheels.
Follow these guidelines when using tractiondevices:
•If possible, avoid fully loading yourvehicle
•Purchase chains or cables from amanufacturer that clearly labels body totire dimension restrictions.
•When driving with snow chains or cables,do not exceed 30 mph (48 km/h) or themaximum speed recommended by thechain manufacturer; whichever is less.
•Drive cautiously. If you hear the chainsor cables rub or bang against the vehicle,stop and retighten them. If this does notwork, remove the chains or cables andprevent vehicle damage.
•Remove the chains or cables when theyare no longer needed. Do not use thechains or cables on dry roads.
•If a temporary spare tire is mounted onyour vehicle, do not use snow chains onthe axle with the temporary spare tire.
If you have any questions regarding snowtires or snow chains, please contact yourauthorized dealer.

TIRE PRESSURE MONITORING
SYSTEM
WARNING: The tire pressuremonitoring system is not a substitute formanually checking tire pressures. You shouldperiodically check tire pressures using apressure gauge. Failure to correctly maintaintire pressures could increase the risk of tirefailure, loss of control, vehicle rollover andpersonal injury.
Note: You should only use tire sealants inroadside emergencies as they may causedamage to the tire pressure monitoringsystem sensor.
Note: If the tire pressure monitoring systemsensor becomes damaged, it may notfunction.
Each tire, including the spare (ifprovided), should be checkedmonthly when cold and inflated tothe inflation pressure recommended by thevehicle manufacturer on the vehicle placardor tire inflation pressure label. (If your vehiclehas tires of a different size than the sizeindicated on the vehicle placard or tireinflation pressure label, you shoulddetermine the proper tire inflation pressurefor those tires).
As an added safety feature, your vehicle hasbeen equipped with a Tire PressureMonitoring System (TPMS) that illuminates alow tire pressure telltale when one or moreof your tires is significantly under-inflated.Accordingly, when the low tire pressuretelltale illuminates, you should stop andcheck your tires as soon as possible, andinflate them to the proper pressure. Drivingon a significantly under-inflated tire causesthe tire to overheat and can lead to tirefailure. Under-inflation also reduces fuelefficiency and tire tread life, and may affectthe vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitutefor proper tire maintenance, and it is thedriver’s responsibility to maintain correct tirepressure, even if under-inflation has notreached the level to trigger illumination ofthe TPMS low tire pressure telltale.
Your vehicle has also been equipped with aTPMS malfunction indicator to indicate whenthe system is not operating properly. TheTPMS malfunction indicator is combined withthe low tire pressure telltale. When thesystem detects a malfunction, the telltale willflash for approximately one minute and thenremain continuously illuminated. Thissequence will continue upon subsequentvehicle start-ups as long as the malfunctionexists.
When the malfunction indicator is illuminated,the system may not be able to detect orsignal low tire pressure as intended. TPMSmalfunctions may occur for a variety ofreasons, including the installation ofreplacement or alternate tires or wheels onthe vehicle that prevent the TPMS from

functioning properly. Always check the TPMSmalfunction telltale after replacing one ormore tires or wheels on your vehicle toensure that the replacement or alternate tiresand wheels allow the TPMS to continue tofunction properly.
This device complies with Part 15 of the FCCRules and with License exempt RSSStandards of Industry Canada. Operation issubject to the following two conditions:
1. This device may not cause harmfulinterference, and
2.This device must accept any interferencereceived, including interference that maycause undesired operation.
Note:Changes or modifications notexpressively approved by the partyresponsible for compliance could void theuser's authority to operate the equipment.The term "IC:" before the radio certificationnumber only signifies that Industry Canadatechnical specifications were met.
Changing Tires With a Tire PressureMonitoring System
Note:Each road tire is equipped with a tirepressure sensor located inside the wheeland tire assembly cavity. The pressuresensor is attached to the valve stem. Thepressure sensor is covered by the tire andis not visible unless the tire is removed. Takecare when changing the tire to avoiddamaging the sensor.
You should always have your tires servicedby an authorized dealer.
Check the tire pressure periodically (at leastmonthly) using an accurate tire gauge. SeeWhen Inflating Your Tires in this chapter.
Understanding Your Tire PressureMonitoring System
The tire pressure monitoring systemmeasures pressure in your road tires andsends the tire pressure readings to yourvehicle. You can view the tire pressurereadings through the information display.See General Information (page 110). The lowtire pressure warning light will turn on if thetire pressure is significantly low. Once the

light is illuminated, your tires areunder-inflated and need to be inflated to themanufacturer’s recommended tire pressure.Even if the light turns on and a short timelater turns off, your tire pressure still needsto be checked.
When Your Temporary Spare Tire isInstalled
When one of your road tires needs to bereplaced with the temporary spare, thesystem will continue to identify an issue toremind you that the damaged road wheeland tire assembly needs to be repaired andput back on your vehicle.
To restore the full function of the tirepressure monitoring system, have thedamaged road wheel and tire assemblyrepaired and remounted on your vehicle.
When You Believe Your System is NotOperating Properly
The main function of the tire pressuremonitoring system is to warn you when yourtires need air. It can also warn you in theevent the system is no longer capable offunctioning as intended. See the followingchart for information concerning your tirepressure monitoring system:

When Inflating Your Tires
WARNING: Do not use the tirepressure displayed in the information displayas a tire pressure gauge. Failure to followthis instruction could result in personal injuryor death.
When putting air into your tires (such as at agas station or in your garage), the tirepressure monitoring system may not respondimmediately to the air added to your tires.
It may take up to two minutes of driving over20 mph (32 km/h) for the light to turn off afteryou have filled your tires to therecommended inflation pressure.
How Temperature Affects Your TirePressure
The tire pressure monitoring system monitorstire pressure in each pneumatic tire. Whiledriving in a normal manner, a typicalpassenger tire inflation pressure mayincrease about 2–4 psi (14–28 kPa) from acold start situation. If the vehicle is stationaryovernight with the outside temperature
significantly lower than the daytimetemperature, the tire pressure may decreaseabout 3 psi (21 kPa) for a drop of 30°F (17°C)in ambient temperature. This lower pressurevalue may be detected by the tire pressuremonitoring system as being significantlylower than the recommended inflationpressure and activate the system warninglight for low tire pressure. If the low tirepressure warning light is on, visually checkeach tire to verify that no tire is flat. If one ormore tires are flat, repair as necessary.Check the air pressure in the road tires. Ifany tire is under-inflated, carefully drive thevehicle to the nearest location where air canbe added to the tires. Inflate all the tires tothe recommended inflation pressure.
CHANGING A ROAD WHEEL (If
Equipped)
WARNING: If the tire pressure monitorsensor becomes damaged it may notfunction.
Note:The tire pressure monitoring systemindicator light illuminates when the sparetire is in use. To restore the full function ofthe monitoring system, all road wheelsequipped with tire pressure monitoringsensors must be mounted on the vehicle.
Note:You should only use tire sealants inroadside emergencies as they may causedamage to the tire pressure monitoringsystem sensor.
If you get a flat tire when driving, do notapply the brake heavily. Instead, graduallydecrease your speed. Hold the steeringwheel firmly and slowly move to a safe placeon the side of the road.
Have a flat serviced by an authorized dealerin order to prevent damage to the tirepressure monitoring system sensors. SeeTire Pressure Monitoring System (page 352).Replace the spare tire with a road tire assoon as possible. During repairing orreplacing of the flat tire, have an authorizeddealer inspect the tire pressure monitoringsystem sensor for damage.

Dissimilar Spare Wheel and TireAssembly Information
WARNING: Failure to follow theseguidelines could result in an increased riskof loss of vehicle control, injury or death.
If you have a dissimilar spare wheel and tire,then it is intended for temporary use only.This means that if you need to use it, youshould replace it as soon as possible with aroad wheel and tire assembly that is thesame size and type as the road tires andwheels that were originally provided. If thedissimilar spare tire or wheel is damaged, itshould be replaced rather than repaired.
Important Use of Spare Wheel
A dissimilar spare wheel and tire assembly is defined as a spare wheel and tire assembly that is different in brand, size or appearancefrom the road tires and wheels and can be one of three types:
Types of Spare Wheels
T-type mini-spare.1
Full-size dissimilar spare with label on wheel.2
Full-size dissimilar spare without label on wheel.
