2018 LINCOLN MKX tire pressure

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:

Make sure tires are at the proper pressure. See Inflating your tiresin this chapter. After inflating your tires to the manufacturer’srecommended pressure as shown on the Tire Label (located onthe edge of driver’s door or the B-Pillar), the vehicle must be drivenfor at least two minutes over 20 mph (32 km/h) before the lightturns off.

When Inflating Your Tires
WARNING
Do not use the tire pressure displayedin the information display as a tirepressure gauge. Failure to follow thisinstruction could result in personal injury ordeath.
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 stationary
overnight with the outside temperaturesignificantly 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)
WARNINGS
Do not use tire sealants as they maydamage the tire pressure monitoringsystem.
WARNINGS
If the tire pressure monitor sensorbecomes damaged it may not function.
Note:The use of tire sealant may damageyour tire pressure monitoring system andshould only be used in roadsideemergencies. If you must use a sealant, usethe Lincoln Tire Mobility Kit sealant. The tirepressure monitoring system sensor andvalve stem on the wheel must be replacedby an authorized dealer after use of thesealant.
Note:The tire pressure monitoring systemindicator light will illuminate 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.
If you get a flat tire while driving, do not applythe 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 369).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 these guidelines couldresult in an increased risk of loss ofvehicle 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 by Ford.If the dissimilar spare tire or wheel isdamaged, it should be replaced rather thanrepaired.
A dissimilar spare wheel and tire assemblyis defined as a spare wheel and tire assemblythat is different in brand, size or appearancefrom the road tires and wheels and can beone of three types:
1. T-type mini-spare: This spare tire beginswith the letter T for tire size and may haveTemporary Use Only molded in the sidewall.
2. Full-size dissimilar spare with label onwheel: This spare tire has a label on thewheel that states: THIS WHEEL AND TIREASSEMBLY FOR TEMPORARY USE ONLY.
When driving with one of the dissimilar sparetires listed above, do not:
•Exceed 50 mph (80 km/h).
•Load the vehicle beyond maximumvehicle load rating listed on the SafetyCompliance Label.
•Tow a trailer.
•Use snow chains on the end of thevehicle with the dissimilar spare tire.
•Use more than one dissimilar spare tireat a time.
•Use commercial car washing equipment.
•Try to repair the dissimilar spare tire.
Use of one of the dissimilar spare tires listedabove at any one wheel location can lead toimpairment of the following:
•Handling, stability and brakingperformance.
•Comfort and noise.
•Ground clearance and parking at curbs.
•Winter weather driving capability.
•Wet weather driving capability.
•All-wheel driving capability (if applicable).
3. Full-size dissimilar spare without labelon wheel
