spare wheel LINCOLN NAVIGATOR 2018 User Guide

Improper or inadequate vehiclemaintenance can cause tires to wearabnormally. Inspect all your tires,including the spare, frequently, andreplace them if one or more of thefollowing conditions exist:
Tire Wear
When the tread is worn down to onesixteenth of an inch (2 millimeters), tiresmust be replaced to help prevent yourvehicle from skidding and hydroplaning.Built-in treadwear indicators, or wearbars, which look like narrow strips ofsmooth rubber across the tread willappear on the tire when the tread isworn down to one sixteenth of an inch(2 millimeters).
When the tire tread wears down to thesame height as these wear bars, the tireis worn out and must be replaced.
Damage
Periodically inspect the tire treads andsidewalls for damage (such as bulges inthe tread or sidewalls, cracks in the
tread groove and separation in the treador sidewall). If damage is observed orsuspected have the tire inspected by atire professional. Tires can be damagedduring off-road use, so inspection afteroff-road use is also recommended.
Age
WARNING: Tires degrade overtime depending on many factors suchas weather, storage conditions, andconditions of use (load, speed, inflationpressure) the tires experiencethroughout their lives.
WARNING: In general, tiresshould be replaced after six yearsregardless of tread wear. However,heat caused by hot climates orfrequent high loading conditions canaccelerate the aging process and mayrequire tires to be replaced morefrequently.
WARNING: You should replaceyour spare tire when you replace theroad tires or after six years due toaging even if it has not been used.

Highway Hazards
No matter how carefully you drivethere’s always the possibility that youmay eventually have a flat tire on thehighway. Drive slowly to the closest safearea out of traffic. This may furtherdamage the flat tire, but your safety ismore important.
If you feel a sudden vibration or ridedisturbance while driving, or you suspectyour tire or vehicle has been damaged,immediately reduce your speed. Drivewith caution until you can safely pull offthe road. Stop and inspect the tires fordamage. If a tire is under-inflated ordamaged, deflate it, remove wheel andreplace it with your spare tire and wheel.If you cannot detect a cause, have the
vehicle towed to the nearest repairfacility or tire dealer to have the vehicleinspected.
Tire and Wheel Alignment
A bad jolt from hitting a curb or potholecan cause the front end of your vehicleto become misaligned or cause damageto your tires. If your vehicle seems topull to one side when you’re driving, thewheels may be out of alignment. Havean authorized dealer check the wheelalignment periodically.
Wheel misalignment in the front or therear can cause uneven and rapidtreadwear of your tires and should becorrected by an authorized dealer.Front-wheel drive vehicles and thosewith an independent rear suspensionmay require alignment of all four wheels.
The tires should also be balancedperiodically. An unbalanced tire and
wheel assembly may result in irregulartire wear.
Tire Rotation
WARNING: If the tire label showsdifferent tire pressures for the frontand rear tires and the vehicle has atire pressure monitoring system, thenyou need to update the settings forthe system sensors. Always performthe system reset procedure after tirerotation. If you do not reset the system,it may not provide a low tire pressurewarning when necessary.
Note:If your tires show uneven wearask an authorized dealer to check forand correct any wheel misalignment,tire imbalance or mechanical probleminvolved before tire rotation.

Note:Your vehicle may be equippedwith a dissimilar spare wheel and tireassembly. A dissimilar spare wheel andtire assembly is defined as a sparewheel and tire assembly that is differentin brand, size or appearance from theroad tires and wheels. If you have adissimilar spare wheel and tire assemblyit is intended for temporary use only andshould not be used in a tire rotation.
Note:After having your tires rotated,inflation pressure must be checked andadjusted to the vehicle requirements.
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.
Rear-wheel drive vehicles andfour-wheel drive vehicles (front tires atleft of diagram)
Sometimes irregular tire wear can becorrected by rotating the tires.
USING SNOW CHAINS
WARNING: Snow tires must be thesame size, load index and speed rating asthose originally provided by Ford. Use ofany tire or wheel not recommended byFord can affect the safety and performanceof your vehicle, which could result in anincreased risk of loss of control, vehiclerollover, personal injury and death.Additionally, the use of non-recommended
tires and wheels can cause steering,suspension, axle, transfer case or powertransfer unit failure. Follow the Fordrecommended tire inflation pressure foundon the Safety Compliance CertificationLabel (on the door hinge pillar, door latchpost or the door edge that meets the doorlatch post, next to the driver seat), or TireLabel on the B-Pillar or the edge of thedriver door. Failure to follow the tirepressure recommendations can causeuneven treadwear patterns and adverselyaffect the way your vehicle handles.
Note:The suspension insulation andbumpers will help prevent vehicle damage.Do not remove these components from yourvehicle when using snow tires and chains.
The tires on your vehicle have all-weathertreads to provide traction in rain and snow.However, in some climates, you may needto use snow tires and cables. If you need touse cables, it is recommended that steelwheels (of the same size and specifications)be used, as cables may chip aluminumwheels.

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.

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 119). 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 Inflating Your Tires
WARNING: Do not use the tirepressure displayed in the informationdisplay as a tire pressure gauge. Failure tofollow this instruction could result inpersonal injury or 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
WARNING: If the tire pressuremonitor sensor becomes damaged it maynot function.
Note:You should only use tire sealants inroadside emergencies as they may causedamage to the tire pressure monitoringsystem sensor.
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 this vehicle.
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 systemsensors. See Tire Pressure MonitoringSystem (page 409). Replace the spare tirewith a road tire as soon as possible. Duringrepairing or replacing of the flat tire, havethe authorized dealer inspect the systemsensor for damage.
