engine LINCOLN MKZ 2019 Owners Manual

Because your vehicle’s engine iselectronically-controlled by a computer,some engine control settings are maintainedby power from the battery. Some enginecomputer settings, like the idle trim and fueltrim strategy, optimize the driveability andperformance of the engine. The clock andradio station presets are also maintained inmemory by power from the low-voltagebattery. These settings are erased when atechnician disconnects and connects thelow-voltage battery.
To restore the settings, do the following:
Note:Until you switch the ignition to the onposition, you will receive a message in yourinformation display stating that your vehicleis not in park.
1. Apply the parking brake.

5. Run the engine until it reaches normaloperating temperature. While the engineis warming up, complete the following:Reset the clock. See Audio Unit (page391). Reset the power windowsbounce-back feature. See PowerWindows (page 95). Reset the radiostation presets. See Audio Unit (page391).
6. Allow the engine to idle for at least oneminute.
7.Drive the vehicle at least 10 mi (16 km) tocompletely relearn the idle trim and fueltrim strategy.
Note:If you do not allow the engine torelearn the idle and fuel trim strategy, theidle quality of your vehicle may be adverselyaffected until the engine computereventually relearns the idle trim and fuel trimstrategy.
Note:Certain features may not operate ifthe battery monitor system is not reset witha scan tool following a jump start or batteryreplacement. Normal electrical accessoryoperation should resume after your vehicleis left undisturbed for 8 hours.

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 is reinflated witha sealing compound and air. After the tirehas been inflated, you need to drive thevehicle about 3.7 mi (6 km) to distributethe sealant in the tire.
•In the second stage, you need to checkthe tire pressure and adjust, if necessary,to the vehicle's specified tire inflationpressure.
First Stage: Reinflating the Tire withSealing Compound and Air
WARNING: Do not stand directlybeside the tire while the compressor isoperating. This could cause personal injuryif the tire bursts.
Note:If the tire does not inflate to therecommended tire pressure within 15minutes, stop and call roadside assistance.
WARNING: Watch the sidewall of thetire when inflating. If any cracks, bumps orsimilar damage appears, switch thecompressor off and let the air out by meansof the pressure relief valve. Do not continuedriving with this tire. This could cause lossof vehicle control.
WARNING: Do not run the enginewhen operating the air compressor unlessthe vehicle is outdoors or in a well-ventilatedarea.
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.

4. Plug the power cable into the 12-voltpower point in the vehicle.
5.Remove the warning sticker found on thecasing/housing and place it on the centerof the steering wheel.
6. Start the vehicle and leave the enginerunning so the compressor does notdrain the vehicle’s battery.
7. Turn dial (A) clockwise to the sealantposition. Turn the kit on by pressing theon/off button (B).
8.Inflate the tire to the pressure shown onthe tire label located on the edge ofdriver’s door or the door jamb area. Forthe first 45-60 seconds when the sealantis being pumped into the tire, the airpressure gauge may indicate a pressurehigher than the label pressure.This isnormal and should be no reason forconcern. The pressure gauge readingindicates the tire inflation pressure afterabout 60 seconds of operation duringthe tire repair process. The final tirepressure should be checked with thecompressor turned OFF in order to getan accurate pressure reading.
