2016 FORD F250 SUPER DUTY engine

STEERING
To help prevent damage to the powersteering system:
•Never hold the steering wheel at itsfurthest turning points (until it stops)for more than three to five secondswhen the engine is running.
•Do not operate the vehicle with a lowpower steering pump fluid level (belowthe MIN mark on the reservoir).
•Some noise is normal during operation.If excessive, check for low powersteering pump fluid level beforeseeking service by your dealer.
•Heavy or uneven efforts may be causedby low power steering fluid. Check forlow power steering pump fluid levelbefore seeking service by your dealer.
•Do not fill the power steering pumpreservoir above the MAX mark on thereservoir, as this may result in leaksfrom the reservoir.
If the power steering system breaks down(or if the engine is turned off), you cansteer the vehicle manually, but it takesmore effort.
If the steering wanders or pulls, check for:
•an improperly inflated tire
•uneven tire wear
•loose or worn suspension components
•loose or worn steering components
•improper vehicle alignment
If any steering components are serviced orreplaced, install new fasteners (many arecoated with thread adhesive or haveprevailing torque features which may notbe re-used). Never re-use a bolt or nut.Torque fasteners to specifications.
A high crown in the road or high crosswindsmay also make the steering seem towander or pull.

TOWING A TRAILER
WARNINGS
Do not exceed the GVWR orthe GAWR specified on thecertification label.
Towing trailers beyond themaximum recommendedgross trailer weight exceeds thelimit of the vehicle and couldresult in engine damage,transmission damage, structuraldamage, loss of vehicle control,vehicle rollover and personalinjury.
Your vehicle may have electricalitems, such as fuses or relays,related to towing. See the Fuseschapter.
Your vehicle's load capacitydesignation is by weight, not byvolume, so you cannot necessarilyuse all available space whenloading a vehicle or trailer.
Towing a trailer places an extraload on your vehicle's engine,transmission, axle, brakes, tiresand suspension. Inspect thesecomponents periodically during,and after, any towing operation.
Load Placement
To help minimize how trailermovement affects your vehiclewhen driving:
•Load the heaviest items closestto the trailer floor.
•Load the heaviest itemscentered between the left andright side trailer tires.
•Load the heaviest items abovethe trailer axles or just slightlyforward toward the trailertongue. Do not allow the finaltrailer tongue weight to goabove or below 10-15% of theloaded trailer weight.
•Select a tow bar with thecorrect rise or drop. When boththe loaded vehicle and trailerare connected, the trailer frameshould be level, or slightlyangled down toward yourvehicle, when viewed from theside.
When driving with a trailer orpayload, a slight takeoff vibrationor shudder may be present due tothe increased payload weight.Additional information regardingproper trailer loading and settingyour vehicle up for towing islocated in another chapter of thismanual. See Load Limit (page185).

TRAILER SWAY CONTROL (If
Equipped)
WARNING
Turning off trailer sway controlincreases the risk of loss of vehiclecontrol, serious injury or death. Forddoes not recommend disabling this featureexcept in situations where speed reductionmay be detrimental (such as hill climbing),the driver has significant trailer towingexperience, and can control trailer swayand maintain safe operation.
Note:This feature does not prevent trailersway, but reduces it once it begins.
Note:This feature cannot stop all trailersfrom swaying.
Note:In some cases, if vehicle speed is toohigh, the system may activate multipletimes, gradually reducing vehicle speed.
This feature applies your vehicle brakes atindividual wheels and, if necessary, reducesengine power. If the trailer begins to sway,the stability control light flashes and themessage TRAILER SWAY REDUCESPEED appears in the information display.The first thing to do is slow your vehicledown, then pull safely to the side of theroad and check for proper tongue load andtrailer load distribution. See LoadCarrying (page 185).
RECOMMENDED TOWING
WEIGHTS
Note:Make sure to take intoconsideration trailer frontal area.Do not exceed 60 feet2 (5.6
meters2) trailer frontal area for
conventional trailers. Do notexceed 75 feet2 (6.9 meters2) trailer
frontal area for 5th wheel andgooseneck trailers.
Note:Exceeding this limitationmay significantly reduce theperformance of your towingvehicle. Selecting a trailer with alow aerodynamic drag and roundedfront design helps optimizeperformance and fuel economy.
Note:For high altitude operation,reduce the gross combined weightby 2% per 1000 feet (300 meters)starting at the 1000 foot (300meter) elevation point.
Note:Certain states requireelectric trailer brakes for trailersover a specified weight. Be sure tocheck state regulations for thisspecified weight. The maximumtrailer weights listed may be limitedto this specified weight, as yourvehicle's electrical system may notinclude the wiring connector
needed to use electric trailerbrakes.

Calculating the MaximumLoaded Trailer Weight for YourVehicle
1. Start with the gross combinedweight rating for your vehiclemodel and axle ratio. See theprevious chart.
2.Subtract all of the followingthat apply to your vehicle:
•Vehicle curb weight
•Hitch hardware weight, such asa draw bar, ball, locks or weightdistributing hardware
•Driver weight
•Passenger(s) weight
•Payload, cargo and luggageweight
•Aftermarket equipment weight.
This equals the maximum loadedtrailer weight for this combination.
Note:The trailer tongue load isconsidered part of the payload foryour vehicle. Reduce the totalpayload by the final trailer tongueweight.
Note:Consult an authorized dealerto determine the maximum trailerweight allowed for your vehicle ifyou are not sure.
ESSENTIAL TOWING CHECKS
Follow these guidelines for safe towing:
•Do not tow a trailer until you drive yourvehicle at least 1000 miles (1600kilometers).
•Consult your local motor vehicle lawsfor towing a trailer.
•See the instructions included withtowing accessories for the properinstallation and adjustmentspecifications.
•Service your vehicle more frequently ifyou tow a trailer. See your scheduledmaintenance information.
•If you use a rental trailer, follow theinstructions the rental agency givesyou.
See Load limits in the Load Carryingchapter for load specification terms foundon the tire label and Safety Compliancelabel and instructions on calculating yourvehicle's load.

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.
