2017 FORD F250 SUPER DUTY sensor

Low Speed AutomaticCancellation
The system does not function at vehiclespeeds below 12.4 mph (20 km/h). Anaudible alarm sounds and the automaticbraking releases if the vehicle drops belowthis speed.
Hilly Condition and Trailer TowUsage
Note:An audible alarm sounds and thesystem shuts down if it applies brakes foran extended period of time. This allows thebrakes to cool. The system functionsnormally again when the brakes havecooled.
Note:When towing with adaptive cruisecontrol, turn on Tow/Haul Mode and DieselEngine Brake.
Select a lower gear when the system isactive in situations such as prolongeddownhill driving on steep grades, forexample in mountainous areas. Thesystem needs additional engine braking inthese situations to reduce the load on thevehicle’s regular brake system to preventit from overheating.
Switching the System Off
Note:The set speed memory erases whenyou switch off the system.
Press and release OFF or switch off theignition.
Detection Issues
WARNING
On rare occasions, detection issuescan occur due to the roadinfrastructures, for example bridges,tunnels and safety barriers. In these cases,the system may brake late orunexpectedly. At all times, you areresponsible for controlling your vehicle,supervising the system and intervening, ifrequired.
The radar sensor has a limited field ofvision. It may not detect vehicles at all ordetect a vehicle later than expected insome situations. The lead vehicle graphicdoes not illuminate if the system does notdetect a vehicle in front of you.

Driving AidsE227388 E142442 E231384

The system uses radar sensors that arelocated inside the tail lamp on each sideof your vehicle. Any dirt, mud and snow infront of the sensors or driving in heavy raincan cause system degradation. Also, othertypes of obstructions in front of the sensorcan cause system degradation. This isreferred to as a ‘blocked’ condition.
Note:Do not apply bumper stickers and/orrepair compound to these areas, this cancause degraded system performance.
If the system detects a degradedperformance condition, a message warningappears in the display screen. The alertindicators remain ON and the system willno longer provides any warnings. You canclear the warning but the alert indicatorsremain illuminated.
A "blocked" condition can be cleared intwo ways:
•After the blockage in front of thesensors is removed or therainfall/snowfall rate decreases orstops, drive for a few minutes in trafficto allow the sensors to detect passingvehicles.
•By cycling the ignition from ON to OFFand then back ON.
Note:If your vehicle has a tow bar with afactory equipped trailer tow module and itis towing a trailer, the sensors willautomatically turn the Blind SpotInformation System off. If your vehicle hasa tow bar but no factory equipped trailertow module, it is recommended to turn theBlind Spot Information System offmanually. Operating the Blind SpotInformation System without the Blind SpotTrailer Tow package and a trailer attachedwill cause poor system performance.
Blind Spot Information Systemwith Trailer Tow (If Equipped)
The Blind Spot Information System withTrailer Tow is designed to aid you indetecting vehicles that may have enteredthe detection area zone (A). The detectionarea is on both sides of your vehicle andtrailer, extending rearward from theexterior mirrors to the end of your trailer.
When a trailer is attached and thecustomer has set up a Blind Spot Trailer,the Blind Spot Information System withTrailer Tow becomes active when drivingforward above 6 mph (10 km/h). SeeTrailer Reversing Aids (page 269).
The Blind Spot Information System withTrailer Tow can be turned off in theinstrument cluster. If the Blind SpotInformation System is turned off, then theBlind Spot Information System with TrailerTow automatically turns off.

System Operation
If you select a trailer in the display screenprior to connecting the trailer, the systemwill load that configuration and theinformation cluster displays a messagewhen the trailer is connected. A secondmessage appears stating Cross TrafficAlert has been turned off; the Blind SpotInformation System with Trailer Tow stillfunctions normally when driving forward.
If no trailer has been set up and a trailer isconnected, the instrument cluster providesa message indicating a trailer is connectedfollowed by a message asking to select atrailer from the existing list of trailers or toadd a trailer. In order for the Blind SpotInformation System with Trailer Tow tofunction, an existing trailer must beselected or a new trailer must be added. Ifthe request is ignored or if you exit thescreen, a message appears prompting youthat the system has been turned off dueto a trailer connect. This message may notappear until your vehicle speed reaches22 mph (35 km/h).
The Blind Spot Information System withTrailer Tow activates when driving forwardfor that particular trailer set up. If theignition is cycled, the Blind SpotInformation System with Trailer Towcontinues to function using the last trailerselected.
Trailer Considerations
The Blind Spot Information System withTrailer Tow is designed to work with anytrailer whose front width is 8.5 ft (2.6 m)or less and total length from the trailerhitch ball to the rear of the trailer is 30 ft(9 m) or less. Different trailers may causea slight change in performance as outlinedbelow.
Large box trailers may cause false alertsto trigger when driving next to buildings ornear parking cars. A false alert may alsooccur while making a 90-degree turn.
Trailers that are 8.5 ft (2.6 m) wide at thefront and have a total length greater than20 ft (6 m) may have delayed alerts frompassing vehicles when the vehicle ispassing at high speed.
A box trailer whose front width is 8.5 ft(2.6 m) may cause early alerts when youare over taking a vehicle.
When towing a clam shell or V-Nose boxtrailer with a front width of 8.5 ft (2.6 m),delayed alerts on merging vehicles that aretraveling the same speed as your vehiclemay occur.
System Errors
If the system senses a problem with theleft or right sensor, the telltale illuminatesand a message appears in the displayscreen. See Information Messages(page 128).
Switching the System Off and On
You can temporarily switch the Blind SpotInformation System off in the displayscreen. See General Information (page111). When the Blind Spot InformationSystem switches off, you do not receivealerts and the display screen shows asystem off message. The telltale in thecluster also illuminates. When you switchthe Blind Spot Information System on oroff, the alert indicators flash twice.
Note:The Blind Spot Information Systemremembers the last selected on or offsetting.
You can also have the Blind SpotInformation System switched offpermanently at an authorized dealer. Onceswitched off permanently, the system canonly be switched back on at an authorizeddealer.

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.
