2017 FORD F450 SUPER DUTY emergency towing

GENERAL INFORMATION
Note:Occasional brake noise is normal. Ifa metal-to-metal, continuous grinding orcontinuous squeal sound is present, thebrake linings may be worn-out. Have thesystem checked by an authorized dealer. Ifyour vehicle has continuous vibration orshudder in the steering wheel while braking,have it checked by an authorized dealer.
Note:Brake dust may accumulate on thewheels, even under normal drivingconditions. Some dust is inevitable as thebrakes wear and does not contribute tobrake noise. See Cleaning the Wheels(page 370).
See Warning Lamps andIndicators (page 105).
Wet brakes result in reduced brakingefficiency. Gently press the brake pedal afew times when driving from a car wash orstanding water to dry the brakes.
Brake Over Accelerator
In the event the accelerator pedalbecomes stuck or entrapped, apply steadyand firm pressure to the brake pedal toslow the vehicle and reduce engine power.If you experience this condition, apply thebrakes and bring your vehicle to a safestop. Move the transmission to park (P),switch the engine off and apply the parkingbrake. Inspect the accelerator pedal forany interference. If none are found and thecondition persists, have your vehicle towedto the nearest authorized dealer.
Brake Assist
Brake assist detects when you brakerapidly by measuring the rate at which youpress the brake pedal. It providesmaximum braking efficiency as long as youpress the pedal, and can reduce stoppingdistances in critical situations.
Anti-lock Brake System
This system helps you maintain steeringcontrol during emergency stops by keepingthe brakes from locking.
This lamp momentarilyilluminates when you switch theignition on. If the light does notilluminate during start up, remains on orflashes, the system may be disabled. Havethe system checked by an authorizeddealer. If the anti-lock brake system isdisabled, normal braking is still effective.
If the brake warning lampremains illuminated after yourelease the parking brake, havethe system checked by an authorizeddealer.
Diesel Engine Braking (If Equipped)
WARNING
Do not use tow/haul or enginebraking when driving in icy or slipperyconditions as the increased brakingcan cause the rear wheels to slide and yourvehicle to swing around with the possibleloss of vehicle control.
This feature increases engine braking athigher engine speeds to provide bettergrade descent control with less brake andtransmission wear and tear. It alsoimproves engine braking when towing orcarrying heavy loads.
Press the button on the switchbank next to the audio unit toswitch the system on or off.
There are two engine brake modes, manualand automatic.
Manual Engine Braking
1. Press the button to switch on manualengine braking.

If this message displays, with no trailerconnected, the problem is with your vehiclewiring or trailer brake controller. Contactan authorized dealer.
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.
