BLIND SPOT INFORMATION SYSTEM
WITH TRAILER COVERAGE
WHAT IS BLIND SPOT INFORMATIONSYSTEM WITH TRAILER COVERAGE
Blind spot information system detectsvehicles that may have entered the blindspot zone. The detection area is on bothsides your vehicle and trailer, extendingrearward from the exterior mirrors to the endof your trailer.
BLIND SPOT INFORMATION SYSTEMWITH TRAILER COVERAGELIMITATIONS
Trailer coverage only supports conventionaltrailers. The system turns off if you select afifth wheel trailer type.
Make sure the trailer width is less than orequal to 8.5 ft (2.6 m) and the length is lessthan 33 ft (10.1 m). If you input values higher,the system turns off.
Some trailers could cause a slight change insystem performance:
•Large box trailers could cause false alertsto occur when driving next toinfrastructures or near parked cars. Afalse alert could also occur while makinga 90-degree turn.
•Trailers that have a width greater than8.5 ft (2.6 m) at the front and have a totallength greater than 20 ft (6 m) couldcause delayed alerts when a vehicle ispassing at high speeds.
•Box trailers that have a width greater than8.5 ft (2.6 m) at the front could causeearly alerts when you pass a vehicle.
•Clam shell or v-nose box trailers with awidth greater than 8.5 ft (2.6 m) at thefront could cause delayed alerts when avehicle traveling the same speed as yourvehicle merges lanes.

You can set-up a trailer to work with the blindspot information system through thetouchscreen. When setting up a trailer, asequence of screens appear asking for trailerinformation.
1.Select type of trailer screen -conventional, fifth wheel or gooseneck.
Note:The system only supports conventionaltrailers.
2.Do you want to set up blind spot withtrailer screen? If no, the system turns off.If yes, the menu goes to the next screen.
3.Is the width less than 9 ft (2.7 m) andlength less than 33 ft (10.1 m)? If no, thesystem turns off. If yes, the menu goesto the next screen.
4.Trailer width measurement. Measure thewidth at the front of the trailer. It is notmeasured at the widest point of thetrailer. The maximum width at the frontof the trailer the system can support is8.5 ft (2.6 m).
Note:You do not need to enter an exacttrailer width measurement. You only needto confirm that the width of the trailer is lessthan 9 ft (2.7 m).
5.Trailer length measurement. The trailerlength is the distance between the trailerhitch ball and the rear of the trailer. Themaximum length that the system cansupport is 33 ft (10.1 m).
6.Enter the length of trailer. The defaultsetting is 18 ft (5.5 m). Toggling up ordown using the menu buttons increasesor decreases the measurement by 1 ft(0.3 m). Select a length that is equal to orwithin 1 ft (0.3 m) of the actual measuredlength. For example, if the actualmeasure length is 23 ft (7 m), toggle thelength in the menu to 24 ft (7.2 m). Thesystem setup saves when you enter thelength of the trailer.
Note:If the trailer is a bike rack or cargorack with electrical lighting, enter a lengthof around 3 ft (1 m). Cross traffic alert remainson for trailers with a length of 3 ft (1 m) orless.
Note:The system requires propermeasurement and measure entry to functionproperly.

WHAT IS PRE-COLLISION ASSIST
Pre-collision assist detects and warns ofapproaching hazards in the roadway. Thesystem provides multiple levels of assistanceto help avoid a collision if your vehicle israpidly approaching another stationaryvehicle, a vehicle traveling in the samedirection as yours, or a pedestrian or cyclistwithin your driving path.
HOW DOES PRE-COLLISION
ASSIST WORK
The system warns the driver of potentialhazards by providing three levels ofassistance.
If your vehicle is rapidly approachingpotential hazards the system provides thefollowing levels of functionality:
1.Alert.
2.Brake Support.
3.Automatic Emergency Braking.
Alert: When active, a flashingvisual warning appears and anaudible warning tone sounds.
Brake Support: The system is designed tohelp reduce the impact speed by preparingthe brakes for rapid braking. The systemdoes not automatically apply the brakes. Ifyou press the brake pedal, the system couldapply additional braking up to maximumbraking force, even if you lightly press thebrake pedal.
Automatic Emergency Braking: Automaticemergency braking may activate if thesystem determines that a collision isimminent.
Note:If you perceive the pre-collision assistalerts as being too frequent or disturbing,then you can reduce the alert sensitivity.Setting the low sensitivity would result infewer and later warnings of a potentialforward collision. The manufacturerrecommends using the high sensitivitysetting where possible.
Note:Automatic emergency brakingperformance is not affected by the sensitivitysetting.
Each system has various levels of detectioncapabilities. See Pre-Collision AssistLimitations (page 322).
PRE-COLLISION ASSIST
PRECAUTIONS
WARNING: You are responsible forcontrolling your vehicle at all times. Thesystem is designed to be an aid and doesnot relieve you of your responsibility todrive with due care and attention. Failureto follow this instruction could result in theloss of control of your vehicle, personalinjury or death.

The rating for the tow vehicle's brakingsystem operation is at the gross vehicleweight rating, not the gross combined weightrating.
Certain states require functioning trailerbrakes for trailers over a specified weight.Be sure to check state regulations for thisspecified weight.
Ford Motor Company recommends separatefunctioning brake systems for trailersweighing more than 1,500 lb (680 kg) whenloaded.
TOWING A TRAILER LIMITATIONS
The vehicle's load capacity designationis by weight, not by volume, so youcannot necessarily use all availablespace when loading a vehicle or trailer.
Note:Your vehicle could have reducedperformance when operating at highaltitudes and when heavily loaded ortowing a trailer. When driving atelevation, to match driving performanceas perceived at sea level, reduce grossvehicle weight and gross combinationweight by 2% per 1,000 ft (300 m)elevation.
LOADING YOUR TRAILER
To help minimize how trailer movementaffects your vehicle when driving:
•Load the heaviest items closest tothe trailer floor.
•Load the heaviest items centeredbetween the left and right side trailertires.
•Load the heaviest items above thetrailer axles or just slightly forwardtoward the trailer tongue. Do notallow the final trailer tongue weightto go above or below 10-15% of theloaded trailer weight. The trailertongue weight should never exceed10% of the maximum towing capacity.
•Select a ball mount with the correctrise or drop. When both the loadedvehicle and trailer are connected, thetrailer frame should be level, orslightly angled down toward yourvehicle, when viewed from the side.
TRAILER TOWING HINTS
Towing a trailer places an extra load on yourvehicle's engine, transmission, axle, brakes,tires and suspension. Periodically inspectthese components during and after anytowing operation.
When driving with a trailer or payload, a slighttakeoff vibration or shudder may be presentdue to the increased payload weight.
