2018 LINCOLN NAVIGATOR warning

TOWING A TRAILER
WARNING: Towing trailersbeyond the maximum recommendedgross trailer weight exceeds the limitof your vehicle and could result inengine damage, transmission damage,structural damage, loss of vehiclecontrol, vehicle rollover and personalinjury.
WARNING: Do not exceed theGVWR or the GAWR specified on thecertification label.
Note: See Recommended TowingWeights (page 310).
Your vehicle may have electrical items,such as fuses or relays, related totowing. See Fuses (page 342).
Your vehicle's load capacity designationis by weight, not by volume, so youcannot necessarily use all availablespace when loading a vehicle or trailer.
Towing a trailer places an extra load onyour vehicle's engine, transmission, axle,brakes, tires and suspension. Inspectthese components periodically during,and after, any towing operation.
Load Placement
To help minimize how trailer movementaffects your vehicle when driving:
•Load the heaviest items closest tothe trailer floor.
•Load the heaviest items centeredbetween the left and right side trailertires.
•Load the heaviest items above thetrailer axles or just slightly forwardtoward the trailer tongue. Do notallow the final trailer tongue weightto go above or below 10-15% of theloaded trailer weight.
•Select a ball mount with the correctrise or drop and load capacity. Whenboth the loaded vehicle and trailerare connected, the trailer frameshould be level, or slightly angleddown toward your vehicle, whenviewed from the side.
When driving with a trailer or payload, aslight takeoff vibration or shudder maybe present due to the increased payloadweight. Additional information regardingproper trailer loading and setting yourvehicle up for towing is located inanother chapter of this manual. SeeLoad Limit (page 293).
You can also find information in the RV& Trailer Towing Guide available at yourauthorized dealer, or online.

Setup
The system is designed to be used with awide variety of trailers. However there aresome trailers that do not have a propersurface and location to mount the sticker.These trailers are not supported. Attemptsto place the sticker on a surface that doesnot meet the sticker placement requirementlisted in Step 3 of the setup instruction orentering inaccurate measurements toproceed through setup can result in impropersystem function.
Accurate measurements are critical to correctsystem function. If you need to checkmeasurements entered or change them youcan access them through the trailer menusin the instrument cluster. Choose the optionto change the sticker from the change trailersettings menu. It is not necessary to removethe sticker if you are just reviewing orchanging measurements.
The following menu warnings or difficultiesmay occur during setup. Tips to resolve themare listed below.
Note:If you still experience issues with thesystem's ability to detect the sticker, see theinformation in the next section regardingsticker lost during system operation.
Measurement A has reached maximum orminimum value:
•The system is designed to work withdrawbars that have a bumper to hitch ballcenter measurement of 4 in (10 cm) to11 in (28 cm) when installed. Do notattempt to use drawbars that have alength outside this range as the systemperformance will be degraded and couldcause improper system function.
•Make sure that the measurement beingmade is the horizontal distance only frombumper and the hitch ball center. Astraight line distance that includes anyvertical rise or drop will increase themeasurement and make it inaccurate.Inaccurate measurements will degradesystem performance and could causeimproper system function. See step 4 ofthe setup instruction to reviewmeasurement instructions.
Measurement B has reached maximum orminimum value:
•Make sure that the sticker placementinstruction in step 3 of the setup hasbeen followed. Stickers placed outsidethe allowed zone will adversely affect thesystem performance and could causeimproper feature function.
•Make sure that the measurement beingmade is the horizontal distance only fromcenter of sticker to the hitch ball center.A straight line distance that includes anyvertical rise or drop will increase themeasurement and cause an inaccuratevalue to be entered into the system. Seestep 4 of the setup for additionalmeasurement instructions.
Measurement C has reached maximum orminimum value:

1.Grab the trailer hitch cover at the bottomand pull towards the rear of the vehicleuntil the bottom of the trailer hitch coverunsnaps from the bumper.
2. Grab the trailer hitch cover at the edgeand rotate until the top of the trailer hitchcover unsnaps from the bumper, thenremove the trailer hitch cover.
To install the trailer hitch cover:
1. Line up the snaps on the trailer hitchcover to the holes on the bumper andpush forward until it snaps into place.
Hitches
WARNING: Do not cut, drill, weld ormodify the trailer hitch. Modifying the trailerhitch could reduce the hitch rating.
Do not use a hitch that either clamps ontothe bumper or attaches to the axle.
Distribute the trailer load so 10-15% of thetotal trailer weight is on the tongue.
Integrated Hitch Rating
WARNING: Towing trailers beyondthe maximum recommended gross trailerweight exceeds the limit of your vehicleand could result in engine damage,transmission damage, structural damage,loss of vehicle control, vehicle rollover andpersonal injury.
The standard integrated hitch has two ratingsdepending on mode of operation:
•Weight-carrying mode requires a drawbar and hitch ball. The draw bar supportsall the vertical tongue load of the trailer.
•Weight-distributing mode requires anaftermarket weight-distributing system,which includes draw bar, hitch ball, springbars and snap-up brackets. This systemdistributes the vertical tongue load of thetrailer between the truck and the trailer.

Note:These are hitch ratings only. Actualvehicle ratings are dependent on engine,transmission and axle combinations.
Weight-distributing Hitch
WARNING: Do not adjust the springbars so that your vehicle's rear bumper ishigher than before attaching the trailer.Doing so will defeat the function of theweight-distributing hitch, which may causeunpredictable handling, and could resultin serious personal injury.
When hooking-up a trailer using aweight-distributing hitch, always use thefollowing procedure:
1. Park the loaded vehicle, without thetrailer, on a level surface.
2. Measure the height to the top of yourvehicle's front wheel opening on thefender. This is H1.
3. Attach the loaded trailer to your vehiclewithout the weight-distributing barsconnected.
4. Measure the height to the top of yourvehicle's front wheel opening on thefender a second time. This is H2.
5. Install and adjust the tension in theweight-distributing bars so that the heightof your vehicle's front wheel opening onthe fender is approximately half the waydown from H2, toward H1.
6. Check that the trailer is level or slightlynose down toward your vehicle. If not,adjust the ball height accordingly andrepeat Steps 2-6.
When the trailer is level or slightly nose downtoward the vehicle:
•Lock the bar tension adjuster in place.
•Check that the trailer tongue securelyattaches and locks onto the hitch.
•Install safety chains, lighting and trailerbrake controls as required by law or thetrailer manufacturer.
Safety Chains
Note:Do not attach safety chains to thebumper. Always connect the safety chainsto the frame or hook retainers of your trailerhitch.
Install trailer safety chains to the trailer hitchas recommended by the manufacturer. Crossthe chains under the trailer tongue and allowenough slack for turning tight corners. Donot allow the chains to drag on the ground.
