WHAT IS PRE-COLLISION ASSIST
Pre-collision assist detects and warns ofapproaching hazards in the roadway. If yourvehicle is rapidly approaching anotherstationary vehicle, a vehicle traveling in thesame direction as yours, or a pedestrianwithin your driving path, the system providesmultiple levels of assistance to help avoid acollision.
HOW DOES PRE-COLLISION
ASSIST WORK
Pre-Collision Assist with AutomaticEmergency Braking
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 flashing visual warningappears and an audible warning tonesounds.
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 could 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 287).

ASSIST SENSORS
Camera.1
Radar sensor (if equipped).2
If a message regarding a blocked sensor orcamera appears in the information display,something is obstructing the radar signals orcamera images. The radar sensor is behindthe fascia cover in the center of the lowergrille. With a blocked sensor or camera, thesystem may not function, or performancemay reduce. See Pre-Collision Assist –Information Messages (page 292).
Note:Proper system operation requires aclear view of the road by the camera. Haveany windshield damage in the area of thecamera's field of view repaired.
Note:If something hits the front end of yourvehicle or damage occurs and your vehiclehas a radar sensor, the radar sensing zonecould change. This could cause missed orfalse vehicle detections. Have your vehicleserviced to have the radar checked forproper coverage and operation.
Note:If your vehicle detects excessive heatat the camera or a potential misalignmentcondition, a message could display in theinformation display indicating temporarysensor unavailability. When operationalconditions are correct, the messagedeactivates. For example, when the ambienttemperature around the sensor decreasesor the sensor recalibrates successfully.

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.
