2018 LINCOLN MKZ tire pressure

What to do when a Tire Is Punctured
A tire puncture within the tire's tread areacan be repaired in two stages with the kit:
•In the first stage, the tire will be reinflatedwith a sealing compound and air. Afterthe tire has been inflated, you will needto drive the vehicle about 3.7 mi (6 km)to distribute the sealant in the tire.
•In the second stage, you will need tocheck the tire pressure and adjust, ifnecessary, to the vehicle's specified tireinflation pressure.
First Stage: Reinflating the Tire withSealing Compound and Air
WARNING
Do not stand directly beside the tirewhile the compressor is operating. Thiscould cause personal injury if the tire bursts.
Note:If the tire does not inflate to therecommended tire pressure within 15minutes, stop and call roadside assistance.
WARNINGS
Watch the sidewall of the tire wheninflating. If any cracks, bumps or similardamage appears, switch the compressor offand let the air out by means of the pressurerelief valve. Do not continue driving with thistire. This could cause loss of vehicle control.
Do not run the engine when operatingthe air compressor unless the vehicleis outdoors or in a well-ventilated area.
Preparation: Park the vehicle in a safe, leveland secure area, away from moving traffic.
Turn the hazard lights on. Apply the parkingbrake and turn the engine off. Inspect theflat tire for visible damage.
Sealant compound contains latex. Useappropriate precautions to avoid any allergicreactions.
Do not remove any foreign object that haspierced the tire. If a puncture is located inthe tire sidewall, stop and call roadsideassistance.
1.Remove the valve cap from the tire valve.
2. Unwrap the dual purpose hose (blacktube) from the back of the compressorhousing.
3. Fasten the hose to the tire valve byturning the connector clockwise. Tightenthe connection securely.

8. Inflate the tire to the pressure listed onthe tire label located on the driver's dooror the door jamb area. The initial airpressure gauge reading may indicate avalue higher than the label pressurewhile the sealing compound is beingpumped into the tire. This is normal andshould be no reason for concern. Thepressure gauge reading will indicate thetire inflation pressure after about 30seconds of operation. The final tirepressure should be checked with thecompressor turned OFF in order to getan accurate pressure reading.
9.When the recommended tire pressure isreached, turn off the kit, unplug thepower cable, and disconnect the hosefrom the tire valve. Re-install the valvecap on the tire valve and return the kit tothe stowage area.
10. Immediately and cautiously, drive thevehicle 3.7 mi (6 km) to distribute thesealant evenly inside the tire. Do notexceed 50 mph (80 km/h).
11. After 3.7 mi (6 km), stop and check thetire pressure. See Second stage:Checking tire pressure.
WARNING
If you experience any unusualvibration, ride disturbance or noisewhile driving, reduce your speed until youcan safely pull off to the side of the road andcall for roadside assistance. Failure to do socould cause you to lose control of yourvehicle and increase the risk of personalinjury or death.

Note:If you experience any unusualvibration, ride disturbance or noise whiledriving, do not proceed to the second stageof this operation.
Second Stage: Checking Tire Pressure
If you have injected sealant in the tire andthe pressure is below 20 psi (1.4 bar),continue to the next step.
Note:If the tire does not inflate to therecommended tire pressure within 15minutes, stop and call roadside assistance.
WARNING
The air compressor power plug maybe hot after use. Allow it to cool beforehandling. Failure to do so could result inpersonal injury.
Check the air pressure of your tires asfollows:
1.Remove the valve cap from the tire valve.
2. Firmly screw the air compressor hoseonto the valve stem by turning clockwise.
3. Push and turn the dial clockwise to theair position.
4. If required, turn on the compressor andadjust the tire to the recommendedinflation pressure shown on the tire labellocated on the driver's door or door jambarea. The tire pressure should bechecked with the compressor turned OFFin order to get an accurate pressurereading.
5. Remove the hoses, re-install the valvecap on the tire and return the kit to thestowage area.
What to do after the Tire has beenSealed
WARNING
If you experience any unusualvibration, ride disturbance or noisewhile driving, reduce your speed until youcan safely pull off to the side of the road andcall for roadside assistance. Failure to do socould cause you to lose control of yourvehicle and increase the risk of personalinjury or death.
After using the kit to seal your tire, you willneed to replace the sealant canister. Sealantcanisters and spare parts can be obtainedat an authorized Lincoln dealer. Emptysealant canisters may be disposed of athome. However, canisters still containingliquid sealant should be disposed of by yourlocal authorized Lincoln dealer or tire dealer,or in accordance with local waste disposalregulation.

TIRE CARE
Important information for 245/40R19low-profile tires and wheels If yourvehicle is equipped with 245/40R19tires, they are low-profile tires. Thesetires and wheels are designed to giveyour vehicle a sport appearance. Withlow-profile tires, you may notice anincrease in road noise and faster tirewear, depending on road conditions anddriving styles. Due to their design,low-profile tires and wheels are moreprone to road damage from potholes,rough or unpaved roads, car wash railsand curb contact than standard tires andwheels.
Note:Your vehicle’s warranty does notcover these types of damage. Tires
should always be kept at the correctinflation pressures and extra cautionshould be taken when operating onrough roads to avoid impacts that couldcause wheel and tire damage.

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 causethe material of the tire to degenerate
and reduce tire life, and excessivetemperature can lead to sudden tirefailure. The grade C corresponds to alevel of performance which all
passenger car tires must meet under theFederal Motor Vehicle Safety StandardNo. 139. Grades B and A representhigher levels of performance on thelaboratory test wheel than the minimumrequired by law.
Glossary of Tire Terminology
•Tire label: A label showing theoriginal equipment tire sizes,recommended inflation pressure andthe maximum weight the vehicle cancarry.
•Tire Identification Number: Anumber on the sidewall of each tireproviding information about the tirebrand and manufacturing plant, tiresize and date of manufacture. Alsoreferred to as DOT code.
•Inflation pressure: A measure of theamount of air in a tire.
•Standard load: A class of P-metric orMetric tires designed to carry amaximum load at set pressure. Forexample: For P-metric tires 35 psi(2.4 bar) and for Metric tires 36 psi(2.5 bar). Increasing the inflationpressure beyond this pressure willnot increase the tire’s load carryingcapability.
•Extra load: A class of P-metric orMetric tires designed to carry aheavier maximum load at 42 psi(2.9 bar). Increasing the inflationpressure beyond this pressure willnot increase the tire’s load carryingcapability.
•kPa: Kilopascal, a metric unit of airpressure.
•PSI: Pounds per square inch, astandard unit of air pressure.
•Cold tire pressure: The tire pressurewhen the vehicle has been stationaryand out of direct sunlight for an houror more and prior to the vehiclebeing driven for 1.0 mi (1.6 km).
