sensor FORD EXPLORER 2023 Workshop Manual

WARNING: The system does notdetect vehicles that are driving in adifferent direction, cyclists or animals.Apply the brakes when necessary. Failureto follow this instruction could result inthe loss of control of your vehicle,personal injury or death.
WARNING: The system does notoperate during hard acceleration orsteering. Failure to take care may leadto a crash or personal injury.
WARNING: Some situations andobjects prevent hazard detection. Forexample low or direct sunlight, inclementweather, unconventional vehicle types,and pedestrians. Apply the brakes whennecessary. Failure to follow thisinstruction could result in the loss ofcontrol of your vehicle, personal injury ordeath.
WARNING: The system may notoperate properly during severe weatherconditions, for example snow, ice, heavyrain and spray. Always drive with duecare and attention. Failure to take caremay result in a crash.
WARNING: The system cannothelp prevent all crashes. Do not rely onthis system to replace driver judgmentand the need to maintain a safe distanceand speed.
Note:Keep the sensors free from snow, iceand large accumulations of dirt.
Using the Pre-Collision AssistSystem
The system is active at speeds aboveapproximately 3 mph (5 km/h) andpedestrian detection is active at speedsup to 50 mph (80 km/h).
If your vehicle is rapidly approachinganother stationary vehicle, a vehicletraveling in the same direction as yours, ora pedestrian within your driving path, thesystem design provides three levels offunctionality:
1.Alert.
2.Brake Support.
3.Active Braking.
Alert: When active, a flashing visualwarning appears and an audible warningtone sounds.
Brake Support: The system design helpsreduce the impact speed by preparing thebrakes for rapid braking. Brake supportdoes not automatically apply the brakes.If you press the brake pedal, the systemcould apply additional braking up tomaximum braking force, even if you lightlypress the brake pedal.
Active Braking: Active braking mayactivate if the system determines that acollision is imminent. The system may helpthe driver reduce impact damage or avoidthe crash completely.

Note:Brake support and active braking areactive at speeds up to 75 mph (120 km/h).If your vehicle has a radar sensor includedwith adaptive cruise control, then brakesupport and active braking are active up tothe maximum speed of the vehicle.
Note:If you perceive pre-collision assistalerts as being too frequent or disturbing,then you can reduce the alert sensitivity,though we recommend using the highestsensitivity setting where possible. Settinglower sensitivity would lead to fewer andlater system warnings.
Distance Indication and Alert (If
Equipped)
Distance indication and alert is a functionthat provides the driver with a graphicalindication of the time gap to otherpreceding vehicles traveling in the samedirection. Distance indication and alertshows one of the graphics that follow inthe information display.
If the time gap to a preceding vehicle issmall, a red visual indication displays tothe driver.
Note:Distance indication and alertdeactivates and the graphics do not displaywhen adaptive cruise control is active.

Evasive Steering Assist (If Equipped)
If your vehicle is rapidly approaching astationary vehicle or a vehicle traveling inthe same direction as your vehicle, thesystem design helps you steer around thevehicle.
The system only activates when all of thefollowing occur:
•The system detects a vehicle aheadand starts to apply active braking.
•You turn the steering wheel in anattempt to steer around the vehicle.
270
2023 Explorer (CTW) Canada/United States of America, enUSA, Edition date: 202209, First-PrintingDriving AidsE358669

After you turn the steering wheel, thesystem applies additional steering torqueto help you steer around the vehicle. Afteryou pass the vehicle, the system appliessteering torque in the opposite direction toencourage you to steer back into the lane.The system deactivates after you fully passthe vehicle.
Note:The system does not automaticallysteer around a vehicle. If you do not turn thesteering wheel, the system does notactivate.
Note:The system does not activate if thedistance to the vehicle ahead is too smalland the system cannot avoid a crash.
Adjusting the Pre-Collision AssistSettings
You can adjust the following settings byusing the touchscreen.
•You can change Alert and DistanceAlert sensitivity to one of three possiblesettings.
•You can switch distance indication andalert on or off.
•If required, you can switch activebraking on or off.
•If required, you can switch evasivesteering assist on or off.
Note:Active braking and evasive steeringassist automatically turn on every time youswitch the ignition on.
Note:If you switch active braking off,evasive steering assist turns off.
Blocked Sensors
Camera.1.
Radar sensor (if equipped).2.
If a message regarding a blocked sensoror camera appears in the informationdisplay, you have obstructed radar signalsor camera images. If your vehicle has aradar sensor, it is behind the fascia coverin the center of the lower grille. With ablocked sensor or camera, the system maynot function, or performance may reduce.The following table lists possible causesand actions for when this messagedisplays.
Camera Troubleshooting
ActionCause
Clean the outside of the windshield in frontof the camera.The windshield in front of the camera isdirty or obstructed in some way.
Wait a short time. It may take severalminutes for the camera to detect that thereis no obstruction.

Radar Troubleshooting (If Equipped)
ActionCause
Clean the grille surface in front of the radaror remove the object causing the obstruc-tion.
The surface of the radar in the grille is dirtyor obstructed in some way.
Wait a short time. It may take severalminutes for the radar to detect that thereis no obstruction.
The surface of the radar in the grille is cleanbut the message remains in the displayscreen.
The system is temporarily disabled. Thesystem automatically reactivates a shorttime after the weather conditions improve.
Heavy rain, spray, snow or fog is interferingwith the radar signals.
The pre-collision assist system is tempor-arily disabled. The system automaticallyreactivates a short time after the weatherconditions improve.
Swirling water or snow or ice on the surfaceof the road may interfere with the radarsignals.
Have the radar checked for proper coverageand operation.Radar is out of alignment due to a front-end impact.
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 zonemay change. This could cause missed orfalse detections. Contact an authorizeddealer to have the radar checked for propercoverage and operation.

•Stand at a minimum of 12 ft(3.66 m) away from the wheeland tire assembly.
•Use both eye and earprotection.
Important: Remember to replacethe wheel valve stems when theroad tires are replaced on yourvehicle.
It is recommended that the twofront tires or two rear tiresgenerally be replaced as a pair ifthe worn tires still have usabledepth.
To avoid potential Four-WheelDrive (4WD) malfunction or(4WD) system damage, it isrecommended to replace all fourtires rather than mixing
significantly worn tires with newtires.
The tire pressure sensors mountedin the wheels (originally installedon your vehicle) are not designedto be used in aftermarket wheels.
The use of wheels or tires notrecommended may affect theoperation of your tire pressuremonitoring system.
If the tire pressure monitoringsystem indicator is flashing, yoursystem is malfunctioning. Yourreplacement tire might beincompatible with your tirepressure monitoring system, orsome component of the systemmay be damaged.
Safety Practices
WARNING: If your vehicleis stuck in snow, mud or sand, donot rapidly spin the tires;spinning the tires can tear thetire and cause an explosion. Atire can explode in as little asthree to five seconds.
WARNING: Do not spin thewheels at over 34 mph(55 km/h). The tires may fail andinjure a passenger or bystander.
Driving habits have a great dealto do with your tire mileage andsafety.
*Observe posted speed limits
*Avoid fast starts, stops and turns
*Avoid potholes and objects onthe road
*Do not run over curbs or hit thetire against a curb when parking
Highway Hazards
No matter how carefully you drive,there is always the possibility thatyou may eventually have a flat tireon the highway. Drive slowly to the
closest safe area out of traffic.This may further damage the flattire, but your safety is moreimportant.
