2016 FORD F450 SUPER DUTY warning

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).

TOWING POINTS
WARNINGS
Using recovery hooks is dangerousand should only be done by a personfamiliar with proper vehicle recoverysafety practices. Improper use of recoveryhooks may cause hook failure or separationfrom the vehicle and could result in seriousinjury or death.
Always slowly remove the slack fromthe recovery strap prior to pulling.Failure to do so can introducesignificantly higher loads which can causethe recovery hooks to break off, or therecovery strap to fail which can causeserious injury or death.
Never link two straps together witha clevis pin. These heavy metalobjects could become projectiles ifthe strap breaks and can cause seriousinjury or death.
Your vehicle comes equipped withframe-mounted front recovery hooks.These hooks should never have a loadapplied to them greater than the grossvehicle weight rating of your vehicle.
Before using recovery hooks:
•Make sure all attaching points aresecure and capable of withstandingthe applied load.
•Never use chains, cables or tow strapswith metal hook ends.
•Only use recovery straps that have aminimum breaking strength two tothree times the gross vehicle weight ofthe stuck vehicle.
•Make sure the recovery strap is in goodcondition and free of visible cuts, tearsor damage.
•Use a damper device such as a tarp,heavy blanket or piece of carpetdraped over the recovery strap to helpabsorb the energy in the event thestrap breaks.
•Make sure the stuck vehicle is notloaded heavier than its gross vehicleweight rating specified on thecertification label.
•Always align the tow vehicle and stuckvehicle in a straight line (within 10degrees).
•Keep bystanders to the sides of thevehicle, at a distance of at least twicethe length of the recovery strap. Thishelps avoid injury from the hazard of arecovery hook or strap breaking, or avehicle lurching into their path.

SNOWPLOWING
Ford recommends that the Super DutyF-Series used for snow removal includethe snowplow package option.
Installing the Snowplow
Weight limits and guidelines for selectingand installing the snowplow are in the FordTruck Body Builders Layout Book,snowplow section, found atwww.fleet.ford.com/truckbbas. A typicalinstallation affects the following:
•Certification to government safety lawssuch as occupant protection and airbagdeployment, braking, and lighting. Lookfor an Alterer’s Label on the vehiclefrom the snowplow installer certifyingthat the installation meets allapplicable Federal Motor VehicleSafety Standards (FMVSS).
•The Total Accessory Reserve Capacity(TARC) is on the lower right side of thevehicle’s Safety ComplianceCertification Label. This applies toFord-completed vehicles of 10,000pounds (4,536 kilograms) GVWR orless. This is the weight ofpermanently-attached auxiliaryequipment, such as snowplowframe-mounting hardware, that canbe added to the vehicle and satisfyFord compliance certification toFMVSS. Exceeding this weight mayrequire the auxiliary equipment installeradditional safety certificationresponsibility. The Front AccessoryReserve Capacity (FARC) is forcustomer convenience.
•Rear ballast weight behind the rearaxle may be required to preventexceeding the FGAWR, and providefront-to-rear weight balance for properbraking and steering.
•Front wheel toe may requirere-adjustment to prevent prematureuneven tire wear. Specifications are inthe Ford Workshop Manual.
•Headlight aim may requirere-adjustment.

•The tire air pressures recommendedfor general driving are on the vehicle’sSafety Certification Label. Themaximum cold inflation pressure forthe tire and associated load rating ison the tire sidewall. Tire air pressuremay require re-adjustment within thesepressure limits to accommodate theadditional weight of the snowplowinstallation.
•Federal and some local regulationsrequire additional exterior lamps forsnowplow-equipped vehicles. Consultyour authorized dealer for additionalinformation.
Operating the Vehicle with theSnowplow Attached
Note:Do not use your vehicle for snowremoval until you have driven at least500 mi (800 km).
Ford recommends vehicle speed does notexceed 45 mph (72 km/h) whensnowplowing.
The attached snowplow blade restrictsairflow to the radiator, and may cause theengine to run at a higher temperature:Attention to engine temperature isespecially important when outsidetemperatures are above freezing. Anglethe blade to maximize airflow to theradiator and monitor engine temperatureto determine whether a left or right angleprovides the best performance.
Follow the severe duty schedule in yourScheduled Maintenance information forengine oil and transmission fluid changeintervals.
Snowplowing with your AirbagEquipped Vehicle
WARNINGS
Do not attempt to service, repair, ormodify the airbag supplementalrestraint system (SRS) or its fuses.Contact an authorized dealer.
Additional equipment such assnowplow equipment may affect theperformance of the airbag sensorsincreasing the risk of injury. Please refer tothe Body Builders Layout Book forinstructions about the appropriateinstallation of additional equipment.
All occupants of the vehicle,including the driver, should alwaysproperly wear their safety belts, evenwhen provided with an airbagsupplemental restraint system (SRS).
Your vehicle is equipped with a driver andpassenger airbag supplemental restraintsystem. The supplemental restraint systemwill activate in certain frontal and offsetfrontal collisions when the vehicle sustainssufficient frontal deceleration.
Careless or high speed driving whileplowing snow that results in sufficientvehicle decelerations can deploy theairbag. Such driving also increases the riskof accidents
Never remove or defeat the trippingmechanisms designed into the snowremoval equipment by its manufacturer.Doing so may cause damage to the vehicleand the snow removal equipment as wellas possible airbag deployment.
Engine temperature while plowing
When driving with a plow, your engine mayrun at a higher temperature than normalbecause the attached snowplow blade willrestrict airflow to the radiator.
