2016 FORD F450 SUPER DUTY brake

Integrated Trailer Brake Controller
(If Equipped)
WARNING
The Ford trailer brake controller hasbeen verified to be compatible withtrailers having electric-actuateddrum brakes (one to four axles) and someelectric-over-hydraulic brakes. It will notactivate hydraulic surge-style trailerbrakes. It is the responsibility of thecustomer to ensure that the trailer brakesare adjusted appropriately, functioningnormally and all electric connections areproperly made. Failure to do so may resultin loss of vehicle control, crash or seriousinjury.
When used properly, the trailer brakecontroller assists in smooth and effectivetrailer braking by powering the trailer’selectric or electric-over-hydraulic brakeswith a proportional output based on thetowing vehicle’s brake pressure.
You can adjust the amount of initial trailerbrake output by selecting one of threesettings through the message center.
Ford has tested the trailer brake controllerto be compatible with several majorbrands of electric-over-hydraulic trailerbrakes. Contact an authorized dealer forinformation on which brands you can use.
The controller user interface consists ofthe following:
A: + and - (Gain adjustment buttons):Pressing these buttons adjusts thecontroller's power output to the trailerbrakes in 0.5 increments. You can increasethe gain setting to 10.0 (maximum trailerbraking) or decrease it to 0 (no trailerbraking). Pressing and holding a buttonraises or lowers the setting continuously.The gain setting displays in the messagecenter as follows: TBC GAIN = XX.X.
B: Manual control lever: Slide the controllever to the left to switch on the trailer'selectric brakes independent of the towvehicle's. See the following Procedure foradjusting gain section for instructions onproper use of this feature. If you use themanual control while the brake is alsoapplied, the greater of the two inputsdetermines the power sent to the trailerbrakes.
•Stop lamps: Using the manual controllever lights both the trailer brake lampsand your vehicle brake lamps.
Trailer brake control messages appear inthe information display as follows:
•TBC GAIN = XX.X NO TRAILER:Shows the current gain setting.
•TBC GAIN = XX.X OUTPUT=/ / / // /: Displays when braking. The barsindicate the amount of power going tothe trailer brakes.
•TRAILER CONNECTED: Displayswhen the system senses a correcttrailer wiring connection.
•TRAILER DISCONNECTED: Displayswhen the system senses a trailerdisconnection.

Trailer Brake Effort Setting
The trailer brake controller allows the userto customize how aggressively the trailerbrakes engage. The default value is "Low"and is the recommended setting for mosttrailers. If your trailer's brakes require moreinitial voltage, or if you prefer moreaggressive trailer braking, then select eitherthe "Medium" or the "High" setting. SeeInformation Displays (page 89).
Procedure for Adjusting Gain
Note:Only perform this procedure in atraffic-free environment at speeds ofapproximately 20-25 mph (30-40 km/h).
The gain setting adjusts 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 trailerwheels may 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 electricor electric-over-hydraulic brakes,TRAILER CONNECTED appears inthe information display.
4. Use the gain adjustment (+ and -)buttons to increase or decrease thegain setting to the desired startingpoint. A gain setting of 6.0 is a goodstarting point for heavier loads.
5. In a traffic-free environment, tow thetrailer on a dry, level surface at a speedof 20-25 mph (30-40 km/h) andsqueeze the manual control levercompletely.
6. If the trailer wheels lock up, indicatedby squealing tires, reduce the gainsetting. If the trailer wheels turn freely,increase the gain setting. Repeat Steps5 and 6 until the gain setting is at apoint just below trailer wheel lock-up.If towing a heavier trailer, trailer wheellock-up may not be attainable evenwith the maximum gain setting of 10.
Information Display Warning Messages
Note:An authorized dealer can diagnosethe trailer brake controller to determineexactly which trailer fault has occurred.However, your Ford warranty does not coverthis diagnosis if the fault is with the trailer.
TRAILER BRAKE MODULE FAULT
Displays in response to faults sensed bythe 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 withdegraded performance.
WIRING FAULT ON TRAILER
Displays when there is a short circuit onthe electric brake output wire.
If this message displays, with no trailerconnected, the problem is with your vehiclewiring or trailer brake controller. Contactan authorized dealer.

Towing

If the message only displays with a trailerconnected, the problem is with the trailerwiring. 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 brakesmay be 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.
•Adjust gain setting, using the procedureabove, whenever road, weather, traileror vehicle loading conditions changefrom when the gain was initially set.
•Only use the manual control lever forproper adjustment of the gain duringtrailer setup. Misuse, such asapplication during trailer sway, couldcause instability of trailer or towvehicle.
•Avoid towing in adverse weatherconditions. The trailer brake controllerdoes not provide anti-lock control ofthe trailer wheels. Trailer wheels canlock up on slippery surfaces, resultingin reduced stability of trailer and towvehicle.
•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 activewhen applying the brakes using yourvehicle's brake pedal, not thecontroller.
•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 workindependently of each other. Changingthe gain setting on the controller doesnot affect the operation of yourvehicle's brakes.
•When you switch the engine off, thecontroller output is disabled and thedisplay and module shut down.
Trailer Lamps
WARNING
Never connect any trailer lamp wiringto the vehicle's tail lamp wiring; thismay 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 upto get the feel of your vehicle-trailercombination before starting on a trip.When turning, make wider turns so thetrailer wheels clear curbs and otherobstacles.
When Towing a Trailer
•Do not drive faster than 70 mph (113km/h) during the first 500 miles (800kilometers).
•Do not make full-throttle starts.
202
Super Duty (TFA) Canada/United States of America, enUSA, First Printing
Towing

•Check your hitch, electrical connectionsand trailer wheel lug nuts thoroughlyafter you have traveled 50 miles (80kilometers).
•When stopped in congested or heavytraffic during hot weather, place thegearshift in position P to aid engine andtransmission cooling and to help A/Cperformance.
•Turn off the speed control with heavyloads or in hilly terrain. The speedcontrol may turn off automaticallywhen you are towing on long, steepgrades.
•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 is equipped with aGrade Assist or Tow/Haul feature, usethis feature when towing. This providesengine braking and helps eliminateexcessive transmission shifting foroptimum fuel economy andtransmission cooling.
•If your vehicle is equipped withAdvanceTrac with RSC, this systemmay turn on during typical corneringmaneuvers with a heavily loaded trailer.This is normal. Turning the corner at aslower speed while towing may reducethis tendency.
•If you are towing a trailer frequently inhot weather, hilly conditions, at thegross combined weight rating (or anycombination of these factors), considerrefilling your rear axle with syntheticgear lubricant (if the axle is not alreadyfilled with it). See Capacities andSpecifications (page 303).
•Allow more distance for stopping witha trailer 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 automatic transmission inposition P.
4. Place wheel chocks in front and backof the trailer wheels. (Chocks notincluded with vehicle.)
Your vehicle may be equipped with atemporary or conventional spare tire. A"temporary" spare tire is different in size(diameter or width), tread-type(All-Season or All Terrain) or is from adifferent manufacturer than the road tireson your vehicle. Consult information on thetire label or Safety Compliance label forlimitations when 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 you remove the trailer from the water.
When backing down a ramp during boatlaunching or retrieval:
•Do not allow the static water level torise above the bottom edge of the rearbumper.
•Do not allow waves to break higherthan 6 inches (15 centimeters) abovethe bottom edge of the rear bumper.
Exceeding these limits may allow water toenter vehicle components:
•Causing internal damage to thecomponents.
•Affecting driveability, emissions, andreliability.

BREAKING-IN
You need to break in new tires forapproximately 300 miles (480kilometers). During this time, your vehiclemay exhibit some unusual drivingcharacteristics.
Avoid driving too fast during the first 1000miles (1600 kilometers). Vary your speedfrequently and change up through thegears early. Do not labor the engine.
Do not tow during the first 1000 miles(1600 kilometers).
ECONOMICAL DRIVING
Your fuel economy is affected by severalthings, such as how you drive, theconditions you drive under, and how youmaintain your vehicle.
You may improve your fuel economy bykeeping these things in mind:
•Accelerate and slow down in a smooth,moderate fashion.
•Drive at steady speeds withoutstopping.
•Anticipate stops; slowing down mayeliminate the need to stop.
•Combine errands and minimizestop-and-go driving.
•Close the windows for high-speeddriving.
•Drive at reasonable speeds (travelingat 55 mph [88 km/h] uses 15% lessfuel than traveling at 65 mph [105km/h]).
•Keep the tires properly inflated and useonly the recommended size.
•Use the recommended engine oil.
•Perform all regularly scheduledmaintenance.
Avoid these actions; they reduce your fueleconomy:
•Sudden accelerations or hardaccelerations.
•Revving the engine before turning it off.
•Idle for periods longer than one minute.
•Warm up your vehicle on coldmornings.
•Use the air conditioner or frontdefroster.
•Use the speed control in hilly terrain.
•Rest your foot on the brake pedal whiledriving.
•Drive a heavily loaded vehicle or tow atrailer.
•Carry unnecessary weight(approximately 1 mpg [0.4 km/L] islost for every 400 lb [180 kilogram] ofweight carried).
•Driving with the wheels out ofalignment.
Conditions
•Heavily loading a vehicle or towing atrailer may reduce fuel economy at anyspeed.
•Adding certain accessories to yourvehicle (for example bug deflectors,rollbars, light bars, running boards, skiracks or luggage racks) may reducefuel economy.
•To maximize the fuel economy, drivewith the tonneau cover installed (ifequipped).
•Using fuel blended with alcohol maylower fuel economy.
•Fuel economy may decrease with lowertemperatures during the first 8–10miles (12–16 kilometers) of driving.
•Driving on flat terrain offers improvedfuel economy as compared to drivingon hilly terrain.

Driving Hints

•Transmissions give their best fueleconomy when operated in the topcruise gear and with steady pressureon the gas pedal.
•Four-wheel-drive operation (ifequipped) is less fuel efficient thantwo-wheel-drive operation.
•Close the windows for high-speeddriving.
DRIVING THROUGH WATER
WARNING
Do not drive through flowing or deepwater as you may lose control of yourvehicle.
Note:Driving through standing water cancause vehicle damage.
Note:Engine damage can occur if waterenters the air filter.
Before driving through standing water,check the depth. Never drive through waterthat is higher than the bottom of the wheelhubs.
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 thatthe steering power assist works.
FLOOR MATS
WARNINGS
Always use floor mats that aredesigned to fit the foot well of yourvehicle. Only use floor mats thatleave the pedal area unobstructed. Onlyuse floor mats that are firmly secured toretention posts so that they cannot slip outof position and interfere with the pedalsor impair safe operation of your vehicle inother ways.
Pedals that cannot move freely cancause loss of vehicle control andincrease the risk of serious personalinjury.
Always make sure that the floormats are properly attached to theretention posts in the carpet that aresupplied with your vehicle. Floor mats mustbe properly secured to both retention poststo make sure mats do not shift out ofposition.
Never place floor mats or any othercovering in the vehicle foot well thatcannot be properly secured toprevent them from moving and interferingwith the pedals or the ability to control thevehicle.
Never place floor mats or any othercovering on top of already installedfloor mats. Floor mats should alwaysrest on top of vehicle carpeting surface andnot another floor mat or other covering.Additional floor mats or any other coveringwill reduce the pedal clearance andpotentially interfere with pedal operation.
