2017 FORD F250 SUPER DUTY Owners Manual

CROSS TRAFFIC ALERT (If
Equipped)
WARNING
Never use the Cross Traffic Alertsystem as a replacement for usingthe interior and exterior mirrors andlooking over your shoulder before backingout of a parking space. Cross Traffic Alertis not a replacement for careful driving.
Note:When a trailer is detected, CrossTraffic Alert automatically turns off.
Cross Traffic Alert is designed to warn youof vehicles approaching from the sideswhen the transmission is in reverse (R).
Using the System
Cross Traffic Alert turns on when you startthe engine and you shift into reverse (R).Once shifted out of reverse (R), CrossTraffic Alert turns off.
Cross Traffic Alert is designed to detectvehicles that approach the rear of yourvehicle with a speed up to 37 mph(60 km/h). Coverage decreases when thesensors are partially, mostly or fullyobstructed. Reversing slowly helpsincrease the coverage area andeffectiveness.
In this first example, the left sensor is onlypartially obstructed; zone coverage to theright is nearly maximized.
Zone coverage also decreases whenparking at shallow angles. Here, the leftsensor is mostly obstructed; zone coverageon that side is severely limited.

System Lights, Messages andAudible Alerts
The Cross Traffic Alert illuminates anamber alert indicator in the outside mirroron the side of your vehicle the approachingvehicle is coming from. Cross Traffic Alertalso sounds an audible alert and amessage appears in the display screenindicating a vehicle is coming from the rightor left. Cross Traffic Alert works with thereverse sensing system that sounds its ownseries of tones. See Rear Parking Aid(page 231).
The system uses radar sensors that arelocated in the tail lamp on each side ofyour vehicle. Do not allow mud, snow orbumper stickers to obstruct these areas,this can cause degraded systemperformance. See Blind SpotInformation System (page 249). If theBlind Spot Information System is blocked,Cross Traffic Alert is also blocked. A CrossTraffic Alert blocked message appears inthe display screen when the transmissionis shifted into reverse (R).

System Limitations
Cross Traffic Alert has its limitations;situations such as severe weatherconditions or debris build-up on the sensorarea may limit vehicle detection.
The following are other situations that maylimit the Cross Traffic Alert performance:
•Adjacently parked vehicles or objectsobstructing the sensors.
•Approaching vehicles passing atspeeds greater than 37 mph(60 km/h).
•Driving in reverse faster than 7 mph(12 km/h).
•Backing out of an angled parking spot.
False Alerts
Note:If your vehicle has a tow bar with afactory equipped trailer tow module and itis towing a trailer, the sensors willautomatically turn the Cross Traffic Alertoff. If your vehicle has a tow bar but nofactory equipped trailer tow module, it isrecommended to turn the Cross Traffic Alertoff manually. Operating Cross Traffic Alertwith a trailer attached will cause poor CrossTraffic Alert performance.
There may be certain instances when thereis a false alert by the Cross Traffic Alertsystem that illuminates the alert indicatorwith no vehicle in the coverage zone. Someamount of false alerts are normal; they aretemporary and self-correct.
System Errors
If Cross Traffic Alert senses a problem withthe left or right sensor a message appearsin the display screen. See InformationMessages (page 128).
Switching the System Off and On
Note:The Cross Traffic Alert switches onwhenever the ignition is switched on andready to provide appropriate alerts whenthe transmission is in reverse (R). CrossTraffic Alert will not remember the lastselected on or off setting.
You can temporarily switch Cross TrafficAlert off in the information display. SeeGeneral Information (page 111). Whenyou switch Cross Traffic Alert off, you donot receive alerts and the display screenshows a system off message.
You can also have Cross Traffic Alertswitched off permanently at an authorizeddealer. Once switched off permanently,the system can only be switched back onat an authorized dealer.
STEERING
Power 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 seconds when theengine 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.

Driving Aids

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.
Adaptive Steering (If Equipped)
WARNING
The adaptive steering system hasdiagnostic checks that continuouslymonitor the system. If a fault isdetected a message displays in theinformation display. Stop your vehicle assoon as it is safe to do so. This warningmessage may clear if the fault is no longerpresent. If an adaptive steering systemwarning message appears each time youstart your vehicle, have the systemchecked as soon as possible.
The adaptive steering system continuallychanges the steering ratio with changes tovehicle speed, optimizing the steeringresponse in all conditions. The system alsochanges when you switch on thetransmission tow/haul feature. When youselect the tow/haul button, the adaptivesteering system reduces vehicle sensitivityto steering inputs at higher vehicle speeds,while maintaining the ease of parking andmaneuverability at low speeds.
Note:The adaptive steering system isdesigned with a locking device. With thelock engaged, the adaptive steering systemremains mechanically locked at a fixedsteering ratio. You may also notice a clickwhen you switch the vehicle on or after youswitch it off, as the lock disengages orengages.
Note:If your vehicle loses electrical poweror detects a fault when you are driving, thesystem automatically shuts down and youretain normal steering function with a fixedsteering ratio. During this time it is possiblethat the steering wheel may not be straightwhen the vehicle is driving straight ahead.In addition, the driver may notice that thesteering wheel angle required to steer thevehicle may be different.
Note:During parking maneuvers, theadaptive steering system balances the driverwork load for various steering wheel inputsand vehicle loading conditions. Underextreme operating conditions the systemlocking device may engage. This strategyprevents overheating and permanentdamage to the adaptive steering system.Typical steering and driving maneuversallow the system to cool and return tonormal operation.

COLLISION WARNING SYSTEM
(If Equipped)
Principle Of Operation (If Equipped)
WARNINGS
This system is an extra driving aid. Itdoes not replace your attention andjudgment, or the need to apply thebrakes. This system does NOTautomatically brake your vehicle. If you failto press the brake pedal when necessary,you may collide with another vehicle.
The collision warning system withbrake support cannot help preventall collisions. Do not rely on thissystem to replace your judgment and theneed to maintain correct distance andspeed.
Note:The system does not detect, warn orrespond to potential collisions with vehiclesto the rear or sides of your vehicle.
Note:The collision warning system is activeat speeds above approximately 5 mph(8 km/h).
Note:The collision warning system will beunavailable if you disable the electronicstability control. See Using StabilityControl (page 227).
The system alerts you of certain collisionrisks. The system's sensor detects yourvehicle's rapid approach to other vehiclestraveling in the same direction as yourvehicle.
When your vehicle rapidly approachesanother vehicle, a red warning light flashesand a tone sounds.
The brake support system assists you inreducing any collision speed bypre-charging the brakes. If the risk ofcollision continues to increases after theaudio-visual warning, the brake supportprepares the brake system for rapidbraking. The system does notautomatically activate the brakes, but ifthe brake pedal is pressed even lightly, thebrakes apply full stopping power.
Using the Collision Warning System
WARNING
The collision warning system’s brakesupport reduces collision speed onlyif you brake your vehicle before anycollision. As in any typical braking situation,you must press your brake pedal.
You can use your information displaycontrol to adjust the collision warningsystem's sensitivity or to turn the systemOn or Off. Your vehicle will rememberthese settings across key cycles. You maychange the collision warning systemsensitivity to any one of three possiblesettings. See General Information (page111).

Note:It is recommended that you turn thecollision warning system off if a snow plowor similar object is installed in such a waythat it may block the radar sensor. Yourvehicle will remember the selected settingacross key cycles.
Note:When possible, the manufacturerrecommends using the highest sensitivitysetting. If warnings are too frequent, you canreduce your system's sensitivity. Reducedsensitivity causes fewer and later systemwarnings. See General Information (page111).
Blocked Sensors
If a blocked sensor message appears in theinformation display, dirt, water, or an objectis blocking the sensor. The sensor islocated behind a cover near the driver sideof the lower grille. If anything blocks thesensor, your vehicle cannot see throughthe sensor, and the collision warningsystem will not work. Possible causes forthe blocked sensor message and correctiveactions are listed below.
ActionCause

System Limitations
WARNING
The collision warning system’s brakesupport only reduces collision speedif you first apply your brakes. Youmust brake as you would in any typicalbraking situation.
Due to the nature of radar technology,there may be certain instances wherevehicles do not provide a collision warning.These include:
•Stationary vehicles or vehicles movingbelow 6 mph (10 km/h).
•Pedestrians or objects in the roadway.
•Oncoming vehicles in the same lane.
•Severe weather conditions (seeblocked sensor section).
•Debris build-up on the grille near theheadlamps (see blocked sensorsection).
•Small distance to vehicle ahead.
•Large steering wheel and pedalmovements (very active driving style).
Damage to the front end of your vehiclemay alter the radar sensor's coverage area.This may result in missed or false collisionwarnings. Have an authorized dealer checkyour radar sensor for proper coverage andoperation.
