2019 LINCOLN NAVIGATOR tow

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.

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 120).
•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 418).
•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

Your vehicle may be equipped with atemporary or conventional spare tire. Atemporary spare tire is different in size(diameter or width), tread-type (All-Seasonor All-Terrain) or is from a differentmanufacturer than the road tires on yourvehicle. Consult information on the tire labelor Safety Compliance label for limitationswhen using.
Launching or Retrieving a Boat orPersonal Watercraft (PWC)
Note:Disconnect the wiring to the trailerbefore backing the trailer into the water.
Note:Reconnect the wiring to the trailerafter removing the trailer from the water.
When backing down a ramp during boatlaunching or retrieval:
•Do not allow the static water level to riseabove the bottom edge of the rearbumper.
•Do not allow waves to break higher than6 in (15 cm) above the bottom edge ofthe rear bumper.
Exceeding these limits may allow water toenter vehicle components:
•Causing internal damage to thecomponents.
•Affecting driveability, emissions, andreliability.
Replace the rear axle lubricant anytime therear axle has been submerged in water.Water may have contaminated the rear axlelubricant, which is not normally checked orchanged unless a leak is suspected or otheraxle repair is required.

BREAKING-IN
You need to break in new tires forapproximately 300 mi (480 km). During thistime, your vehicle may exhibit some unusualdriving characteristics.
Avoid driving too fast during the first 1,000 mi(1,600 km). Vary your speed frequently andchange up through the gears early. Do notlabor the engine.
Do not tow during the first 1,000 mi(1,600 km).
REDUCED ENGINE PERFORMANCE
WARNING: If you continue to driveyour vehicle when the engine isoverheating, the engine could stop withoutwarning. Failure to follow this instructioncould result in the loss of control of yourvehicle.
If the engine coolant temperature gaugeneedle moves to the upper limit position, theengine is overheating. See Gauges (page113).
You must only drive your vehicle for a shortdistance if the engine overheats. Thedistance you can travel depends on ambienttemperature, vehicle load and terrain. Theengine continues to operate with limitedpower for a short period of time.
If the engine temperature continues to rise,the fuel supply to the engine reduces. Theair conditioning switches off and the enginecooling fan operates continually.
1. Gradually reduce your speed and stopyour vehicle as soon as it is safe to doso.
2. Immediately switch the engine off toprevent severe engine damage.
3. Wait for the engine to cool down.
4. Check the coolant level. See EngineCoolant Check (page 364).
5. Have your vehicle checked as soon aspossible.
