2018 LINCOLN NAVIGATOR Owners Manual

WARNING: This vehicle may havemore than one battery. Removing thebattery cables from only one battery doesnot disconnect your vehicle electricalsystem. Make sure you disconnect thebattery cables from all batteries whendisconnecting power. Failure to do so maycause serious personal injury or propertydamage.
Your vehicle is fitted with a Motorcraftmaintenance-free battery which normallydoes not require additional water.
When a battery replacement is required, youmust use a recommended replacementbattery that matches the electricalrequirements of the vehicle.
Note:After cleaning or replacing the battery,make sure you reinstall the battery cover orshield.
Note:If you add electrical accessories orcomponents to the vehicle, it may adverselyaffect the low voltage battery performanceand durability. This may also affect theperformance of other electrical systems inthe vehicle.
For longer, trouble-free operation, keep thetop of the battery clean and dry.
If you see any corrosion on the battery orterminals, remove the cables from theterminals and clean with a wire brush. Youcan neutralize the acid with a solution ofbaking soda and water.
Because your vehicle’s engine iselectronically controlled by a computer, somecontrol conditions are maintained by powerfrom the battery. When the battery isdisconnected or a new battery is installed,the engine must relearn its idle and fuel trimstrategy for optimum driveability andperformance. Flexible fuel vehicles (FFV)must also relearn the ethanol content of thefuel for optimum driveability andperformance.
To restore the settings, do the following:
1. Apply the parking brake.
2. Shift into park (P) or neutral (N).
3. Switch off all accessories.
4. Press the brake pedal and start yourvehicle.
5. Run the engine until it reaches normaloperating temperature. While the engineis warming up, complete the following:Reset the clock. Reset the powerwindows bounce-back feature. SeeWindows and Mirrors (page 104). Resetthe radio station presets. See AudioSystem (page 434).
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.

Maintenance

Note:For flexible fuel vehicles, if you areoperating on E85, you may experience poorstarts or an inability to start the engine anddriveability problems until the fuel trim andethanol content have been relearned.
Make sure that you dispose of old batteriesin an environmentally friendly way. Seekadvice from your local authority aboutrecycling old batteries.
If storing your vehicle for more than 30 dayswithout recharging the battery, werecommend that you disconnect the negativebattery cable to maintain battery charge forquick starting.
Battery Management System (If Equipped)
The battery management system monitorsbattery conditions and takes actions toextend battery life. If excessive battery drainis detected, the system temporarily disablessome electrical systems to protect thebattery.
Systems included are:
•Heated rear window.
•Heated seats.
•Climate control.
•Heated steering wheel.
•Audio unit.
•Navigation system.
A message may appear in the informationdisplays to alert you that battery protectionactions are active. These messages are onlyfor notification that an action is taking place,and not intended to indicate an electricalproblem or that the battery requiresreplacement.
After battery replacement, or in some casesafter charging the battery with an externalcharger, the battery management systemrequires eight hours of vehicle sleep time torelearn the battery state of charge. Duringthis time your vehicle must remain fullylocked with the ignition switched off.
Note:Prior to relearning the battery state ofcharge, the battery management systemmay temporarily disable some electricalsystems.
Electrical Accessory Installation
To make sure the battery managementsystem works correctly, do not connect anelectrical device ground connection directlyto the battery negative post. This can causeinaccurate measurements of the batterycondition and potential incorrect systemoperation.
Note:If you add electrical accessories orcomponents to the vehicle, it may adverselyaffect battery performance and durability.This may also affect the performance ofother electrical systems in the vehicle.

Note:To see a clearer light pattern foradjusting, you may want to block the lightfrom one headlamp while adjusting theother.
3. Switch on the low beam headlamps toilluminate the wall or screen and openthe hood. Cover one of the headlampsso no light hits the wall.
4.For halogen or LED headlamps: On thewall or screen you will observe a lightpattern with a distinct horizontal edgetoward the right. If this edge is not at thehorizontal reference line, you will needto adjust the beam so the edge is at thesame height as the horizontal referenceline.
5. Locate the vertical adjuster on eachheadlamp. Use a #2 Phillips screwdriverto turn the adjuster eithercounterclockwise or clockwise in orderto adjust the vertical aim of theheadlamp.
