brakes LINCOLN NAVIGATOR 2018 Service Manual

The gain setting sets the trailer brakecontroller for the specific towing condition.You should change the setting as towingconditions change. Changes to towingconditions include trailer load, vehicle load,road conditions and weather.
The gain should be set to provide themaximum trailer braking assistance whilemaking sure the trailer wheels do not lockwhen using the brakes. Locked trailer wheelsmay lead to trailer instability.
1.Make sure the trailer brakes are in goodworking condition, functioning normallyand properly adjusted. See your trailerdealer if necessary.
2. Hook up the trailer and make theelectrical connections according to thetrailer manufacturer's instructions.
3.When you plug in a trailer with electric orelectric-over-hydraulic brakes, a messageconfirming connection appears in theinformation display.
4.Use the gain adjustment (+ and -) buttonsto increase or decrease the gain settingto the desired starting point. A gainsetting of 6.0 is a good starting point forheavier loads.
5. In a traffic-free environment, tow thetrailer on a dry, level surface at a speedof 20–25 mph (32–40 km/h) andsqueeze the manual control levercompletely.
6.If the trailer wheels lock up, indicated bysquealing tires, reduce the gain setting.If the trailer wheels turn freely, increasethe gain setting. Repeat Steps 5 and 6until the gain setting is at a point justbelow trailer wheel lock-up. If towing aheavier trailer, trailer wheel lock-up maynot be attainable even with the maximumgain setting of 10.
Explanation of Information Display WarningMessages
Note:An authorized dealer can diagnosethe trailer brake controller to determineexactly which trailer fault has occurred.However, your warranty does not cover thisdiagnosis if the fault is with the trailer.
A message indicating a trailer brake modulefault may display in response to faults sensedby the trailer brake controller, accompaniedby a single tone. If this message appears,contact an authorized dealer as soon aspossible for diagnosis and repair. Thecontroller may still function, but performancemay be degraded.
A message indicating a trailer wiring faultmay display when there is a short circuit onthe electric brake output wire. If this messagedisplays, accompanied by a single tone, withno trailer connected, the problem is with yourvehicle wiring between the trailer brakecontroller and the 7-pin connector at thebumper. If the message only displays with atrailer connected, the problem is with thetrailer wiring. Consult your trailer dealer forassistance. This can be a short to ground(such as a chaffed wire), short to voltage(such as a pulled pin on trailer emergencybreakaway battery) or the trailer brakes maybe drawing too much current.

Points to Remember
Note:Do not attempt removal of the trailerbrake controller without consulting theWorkshop Manual. Damage to the unit mayresult.
•Adjust gain setting before using thetrailer brake controller for the first time.
•Adjust gain setting, using the procedureabove, whenever road, weather andtrailer or vehicle loading conditionschange from when the gain was initiallyset.
•Only use the manual control lever forproper adjustment of the gain duringtrailer setup. Misuse, such as applicationduring trailer sway, could cause instabilityof trailer or tow vehicle.
•Avoid towing in adverse weatherconditions. The trailer brake controllerdoes not provide anti-lock control of thetrailer wheels. Trailer wheels can lock upon slippery surfaces, resulting in reducedstability of trailer and tow vehicle.
•The trailer brake controller is equippedwith a feature that reduces output atvehicle speeds below 11 mph (18 km/h)so trailer and vehicle braking is not jerkyor harsh. This feature is only availablewhen applying the brakes using yourvehicle's brake pedal, not the controller.
•The controller interacts with the brakecontrol system and powertrain controlsystem of your vehicle to provide thebest performance on different roadconditions.
•Your vehicle's brake system and thetrailer brake system work independentlyof each other. Changing the gain settingon the controller does not affect theoperation of your vehicle's brakeswhether you attach a trailer or not.
•When you switch the engine off, thecontroller output is disabled and thedisplay and module shut down. Thecontroller module and display turn onwhen you switch the ignition on.
•The trailer brake controller is only afactory-installed or dealer-installed item.Lincoln is not responsible for warranty orperformance of the controller due tomisuse or customer installation.
Trailer Lamps
WARNING: Never connect any trailerlamp wiring to the vehicle's tail lamp wiring;this may damage the electrical systemresulting in fire. Contact your authorizeddealer as soon as possible for assistancein proper trailer tow wiring installation.Additional electrical equipment may berequired.
Trailer lamps are required on most towedvehicles. Make sure all running lights, brakelights, turn signals and hazard lights areworking.

Towing

Before Towing a Trailer
Practice turning, stopping and backing up toget the feel of your vehicle-trailercombination before starting on a trip. Whenturning, make wider turns so the trailerwheels clear curbs and other obstacles.
When Towing a Trailer
•Do not drive faster than 70 mph(113 km/h) during the first 500 mi(800 km).
•Do not make full-throttle starts.
•Check your hitch, electrical connectionsand trailer wheel lug nuts thoroughly afteryou have traveled 50 mi (80 km).
•When stopped in congested or heavytraffic during hot weather, place thetransmission in park (P) to aid engine andtransmission cooling and to help A/Cperformance.
•Turn off the speed control when carryingheavy loads or in hilly terrain. The speedcontrol may turn off automatically whenyou are towing on long, steep grades.
•Shift to a lower gear when driving downa long or steep hill. Do not apply thebrakes continuously, as they mayoverheat and become less effective.
•If your transmission has a Grade Assistor Tow/Haul feature, use this featurewhen towing. This provides enginebraking and helps eliminate excessivetransmission shifting for optimum fueleconomy and transmission cooling.
•If your vehicle has AdvanceTrac withRSC, this system may turn on duringtypical cornering maneuvers with aheavily loaded trailer. This is normal.Turning the corner at a slower speedwhile towing may reduce this tendency.
•If your vehicle has Adaptive suspension,you can select NORMAL or SPORT drivecontrol modes for better experiencewhen towing a trailer. See InformationDisplays (page 119).
•If you are towing a trailer frequently inhot weather, hilly conditions, at the grosscombined weight rating (or anycombination of these factors), considerrefilling your rear axle with synthetic gearlubricant (if the axle is not already filledwith it). See Capacities andSpecifications (page 422).
•Allow more distance for stopping with atrailer attached. Anticipate stops andbrake gradually.
•Avoid parking on a grade. However, ifyou must park on a grade:
1. Turn the steering wheel to point yourvehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the transmission in park (P).
4.Place wheel chocks in the front and backof the trailer wheels.
Note:Chocks are not included with yourvehicle.

Towing

There are also some things you may want toavoid doing because they reduce your fueleconomy:
•Avoid sudden or hard accelerations.
•Avoid revving the engine before turningoff the car.
•Avoid long idle periods.
•Do not warm up your vehicle on coldmornings.
•Reduce the use of air conditioning andheat.
•Avoid using speed control in hilly terrain.
•Do not rest your foot on the brake pedalwhile driving.
•Avoid carrying unnecessary weight.
•Avoid adding particular accessories toyour vehicle (e.g. bug deflectors,rollbars/light bars, running boards, skiracks).
•Avoid driving with the wheels out ofalignment.
DRIVING THROUGH WATER
WARNING: Do not drive throughflowing or deep water as you may losecontrol of your vehicle.
Note:Driving through standing water cancause vehicle damage.
Note:Engine damage can occur if waterenters the air filter.
Before driving through standing water, checkthe depth. Never drive through water that ishigher than the bottom of the wheel hubs.
When driving through standing water, drivevery slowly and do not stop your vehicle.Your brake performance and traction maybe limited. After driving through water andas soon as it is safe to do so:
•Lightly press the brake pedal to dry thebrakes and to check that they work.
•Check that the horn works.
•Check that the exterior lights work.
•Turn the steering wheel to check that thesteering power assist works.
FLOOR MATS
WARNING: Use a floor mat designedto fit the footwell of your vehicle that doesnot obstruct the pedal area. Failure tofollow this instruction could result in theloss of control of your vehicle, personalinjury or death.
WARNING: Pedals that cannot movefreely can cause loss of vehicle control andincrease the risk of serious personal injury.

and internal damage to the tire. It alsomay result in unnecessary tire stress,irregular wear, loss of vehicle controland accidents. A tire can lose up tohalf of its air pressure and not appearto be flat!
Always inflate your tires to the ourrecommended inflation pressure evenif it is less than the maximum inflationpressure information found on the tire.Our recommended tire inflation pressureis found on the Safety ComplianceCertification Label or Tire Label (affixedto either the door hinge pillar, door-latchpost, or the door edge that meets thedoor-latch post, next to the driver'sseating position), or Tire Label locatedon the B-pillar or the edge of the driver's
door. Failure to follow the tire pressurerecommendations can cause uneventreadwear patterns and adversely affectthe way your vehicle handles.
Note:Do not reduce tire pressure tochange the ride characteristics of thevehicle. If you do not maintain theinflation pressure at the levels specifiedby us, your vehicle may experience acondition known as shimmy. Shimmy isa severe vibration and oscillation in thesteering wheel after the vehicle travelsover a bump or dip in the road that doesnot dampen out by itself. Shimmy mayresult from significant under-inflation ofthe tires, improper tires (load range, size,or type), or vehicle modifications suchas lift-kits. In the event that your vehicleexperiences shimmy, you should slowlyreduce speed by either lifting off theaccelerator pedal or lightly applying thebrakes. The shimmy will cease as thevehicle speed decreases.
Maximum Inflation Pressure is the tiremanufacturer's maximum permissiblepressure and the pressure at which themaximum load can be carried by the tire.This pressure is normally higher than themanufacturer’s recommended coldinflation pressure which can be foundon the Safety Compliance Certification
Label (affixed to either the door hingepillar, door-latch post, or the door edgethat meets the door-latch post, next tothe driver's seating position), or TireLabel located on the B-pillar or the edgeof the driver's door. The cold inflationpressure should never be set lower thanthe recommended pressure on theSafety Compliance Certification Labelor Tire Label.
When weather temperature changesoccur, tire inflation pressures alsochange. A 10°F (6°C) temperature dropcan cause a corresponding drop of 1 psi(7 kPa) in inflation pressure. Check yourtire pressures frequently and adjustthem to the proper pressure which canbe found on the Safety ComplianceCertification Label or Tire Label.
To check the pressure in your tire(s):
1. Make sure the tires are cool, meaningthey are not hot from driving even amile.
