PRINCIPLE OF OPERATION
WARNINGS
To help avoid personal injury, pleaseread and understand the limitationsof the system as contained in thissection. Sensing is only an aid for some(generally large and fixed) objects whenmoving on a flat surface at parking speeds.Certain objects with surfaces that absorbultrasonic waves, surrounding vehicle'sparking aid systems, traffic controlsystems, fluorescent lamps, inclementweather, air brakes, and external motorsand fans may also affect the function ofthe sensing system; this may includereduced performance or a false activation.
To help avoid personal injury, alwaysuse caution when in reverse (R) andwhen using the sensing system.
This system is not designed toprevent contact with small or movingobjects. The system is designed toprovide a warning to assist the driver indetecting large stationary objects to avoiddamaging your vehicle. The system maynot detect smaller objects, particularlythose close to the ground.
Certain add-on devices such as largetrailer hitches, bike or surfboard racksand any device that may block thenormal detection zone of the system, maycreate false beeps.
Note:Keep the sensors, located on thebumper or fascia, free from snow, ice andlarge accumulations of dirt. If the sensorsare covered, the system’s accuracy can beaffected. Do not clean the sensors withsharp objects.
Note:If your vehicle sustains damage tothe bumper or fascia, leaving it misalignedor bent, the sensing zone may be alteredcausing inaccurate measurement ofobstacles or false alarms.
Note:The sensing system cannot be turnedoff when a MyKey is present. See Principleof Operation (page 47).
Note:If you attach certain add-on devicessuch as a trailer or bike rack, the rear sensingsystem may detect that add-on device andtherefore provide warnings. It is suggestedthat you disable the rear sensing systemwhen you attach an add-on device to yourvehicle to prevent these warnings.
The sensing system warns the driver ofobstacles within a certain range of yourvehicle. The system turns on automaticallywhenever you switch the ignition on.
You can turn the system on oroff by pressing the parking aidbutton. If your vehicle does nothave a parking aid button, the system canbe switched off through the informationdisplay menu or from the pop-up messagethat appears once you shift thetransmission into reverse (R). See GeneralInformation (page 91).
If a fault is present in the system, a warningmessage appears in the informationdisplay. See Information Messages(page 102).
REAR PARKING AID (If Equipped)
The rear sensors are only active when thetransmission is in reverse (R). As yourvehicle moves closer to the obstacle, therate of the audible warning increases.When the obstacle is less than 12 in(30 cm) away, the warning soundscontinuously. If the system detects astationary or receding object farther than12 in (30 cm) from the corners of thebumper, the tone sounds for only threeseconds. Once the system detects anobject approaching, the warning soundsagain.

Coverage area of up to 6 ft (1.8 m) fromthe rear bumper. There may be decreasedcoverage area at the outer corners of thebumper.
The system detects certain objects whilethe transmission is in reverse (R) :
•Your vehicle is moving toward astationary object at a speed of 3 mph(5 km/h) or less.
•Your vehicle is not moving, but amoving object is approaching the rearof your vehicle at a speed of 3 mph(5 km/h) or less.
•Your vehicle is moving at a speed ofless than 3 mph (5 km/h) and a movingobject is approaching the rear of yourvehicle at a speed of less than 3 mph(5 km/h).
The system provides audio warnings onlywhen your vehicle is moving or when yourvehicle is stationary and the detectedobstacle is less than 12 in (30 cm) awayfrom the bumper.
Obstacle Distance Indicator (If
Equipped)
The system provides obstacle distanceindication through the information display.The distance indicator displays when thetransmission is in reverse (R).
The indicator displays:
•As the distance to the obstacledecreases the indicator blocksilluminate and move towards thevehicle icon.
•If there is no obstacle detected, thedistance indicator blocks are grayedout.
FRONT PARKING AID (If Equipped)
The front parking aid sensors automaticallyturn on when you shift into reverse (R) ora forward gear.
The front sensors are active when thetransmission is in any position other thanpark (P) and the vehicle speed is below7 mph (12 km/h).
Coverage area of up to 28 in (70 cm) fromthe front bumper. There is decreasedcoverage area at the outer corners.

The system sounds an audible warningwhen obstacles are near either bumper inthe following manner:
•Objects detected by the front sensorsare indicated by a high-pitched tonefrom the front of the vehicle.
•Objects detected by the rear sensorsare indicated by a lower pitched tonefrom the rear of the vehicle.
•The sensing system reports theobstacle which is closest to the frontor rear of the vehicle. For example, ifan obstacle is 12 in (30 cm) from thefront of the vehicle and, at the sametime, an obstacle is only 6 in (15 cm)from the rear of the vehicle, the lowerpitched tone sounds.
•An alternating warning sounds fromthe front and rear if there are objectsat both bumpers that are closer than12 in (30 cm).
The system provides warnings when yourvehicle is moving or when your vehicle isstationary and the detected obstacle isless than 12 in (30 cm) away from thebumper.
REAR VIEW CAMERA
WARNINGS
The rear view camera system is areverse aid supplement device thatstill requires the driver to use it inconjunction with the interior and exteriormirrors for maximum coverage.
Objects that are close to eithercorner of the bumper or under thebumper, might not be seen on thescreen due to the limited coverage of thecamera system.
Back up as slow as possible sincehigher speeds might limit yourreaction time to stop your vehicle.
WARNINGS
Use caution when using the rearvideo camera and the luggagecompartment door is ajar. If theluggage compartment door is ajar, thecamera will be out of position and thevideo image may be incorrect. Allguidelines disappear when the luggagecompartment door is ajar.

The system uses two types of guides tohelp you see what is behind your vehicle:
•Fixed guidelines: Show the actual pathyour vehicle is moving in while reversingin a straight line. This can be helpfulwhen backing into a parking space oraligning your vehicle with anotherobject behind you.
•Centerline: Helps align the center ofyour vehicle with an object (forexample, a trailer).
Note:The image may remain onmomentarily when you shift thetransmission out of reverse (R). If yourvehicle speed reaches 6 mph (10 km/h) or10 seconds elapse and the image remainson, have your system inspected by anauthorized dealer.
Note:When towing, the camera only seeswhat you are towing behind your vehicle.This might not provide adequate coverageas it usually provides in normal operationand you might not see some objects. Insome vehicles, the guidelines may disappearonce you engage the trailer tow connector.
The camera may not operate correctlyunder the following conditions:
•Nighttime or dark areas if one or bothreverse lamps are not operating.
•Mud, water or debris obstructs thecamera's view. Clean the lens with asoft, lint-free cloth and non-abrasivecleaner.
•The camera is misaligned due todamage to the rear of your vehicle.

System Lights and Messages
The Blind Spot Information and CrossTraffic Alert systems illuminate an amberalert indicator in the outside mirror on theside of your vehicle the approachingvehicle is coming from.
The alert indicator dims when the systemdetects nighttime darkness.
Cross Traffic Alert sounds also sounds anaudible alarm and a message appears inthe information display indicating a vehicleis coming from the right or left. CrossTraffic Alert works with the reverse sensingsystem which sounds its own audiblealarm. See Rear Parking Aid (page 182).
System Sensor Blockage
WARNING
Never use the Blind SpotInformation System as areplacement for using the interiorand exterior mirrors or looking over yourshoulder before changing lanes. The BlindSpot Information System is not areplacement for careful driving.
Note:It is possible to get a blockagewarning with no blockage present; this israre and known as a false blockage warning.A false blocked condition eitherself-corrects or clears after a key cycle.
The system uses radar sensors which arelocated behind the bumper fascia on eachside of your vehicle. Do not allow theseareas to become obstructed by mud, snowor bumper stickers, as this can causedegraded system performance.
If the system detects a degradedperformance condition, a blocked sensorwarning or low visibility warning will appearin the information display and the alertindicator illuminates in the appropriatemirror(s). The information display warningcan be cleared but the alert indicatorremains illuminated.
191
Expedition (TB7) Canada/United States of America, enUSA, Edition date: 03/2016, First Printing
Driving AidsE142442 E205199

When the blockage is removed, the systemcan be reset in two ways: 1) when at leasttwo objects are detected while driving, or2) turn the ignition key from on to off, then
back on. If the blockage is still present afterthe key cycle, the system senses again thatit is blocked after driving in traffic.
Reasons for messages being displayed
Clean the fascia area in front of the radaror remove the obstruction.The radar surface is dirty or obstructed
Drive normally in traffic for a few minutesto allow the radar to detect passingvehicles so it can clear the blocked state.
The radar surface is not dirty or obstructed
No action required. The system automatic-ally resets to an unblocked state once therainfall/snowfall rate decreases or stops.Do not use the Blind Spot InformationSystem or Cross Traffic Alert in theseconditions.
Heavy rainfall/snowfall interferes with theradar signals
System Limitations
The Blind Spot Information and CrossTraffic Alert systems do have theirlimitations; situations such as severeweather conditions or debris build-up onthe sensor area may limit vehicle detection.
The following are other situations that maylimit the Blind Spot Information System:
•Certain maneuvering of vehiclesentering and exiting the blind zone.
•Vehicles passing through the blind zoneat very fast rates.
•When several vehicles forming aconvoy pass through the blind zone.
The following are other situations that maylimit the Cross Traffic Alert:
•Adjacently parked vehicles or objectsobstructing the sensors.
•Approaching vehicles passing atspeeds greater than 15 mph (24 km/h).
•Driving in reverse faster than 3 mph(5 km/h).
•Backing out of an angled parking spot.
False Alerts
Note:If you connected a trailer to yourvehicle, the Blind Spot Information Systemmay detect the trailer causing a false alert.To avoid false alerts you may want to turnthe system off manually.
There may be certain instances wheneither the Blind Spot Information or CrossTraffic Alert systems illuminate the alertindicator with no vehicle in the coveragezone; this is known as a false alert. Someamount of false alerts are normal; they aretemporary and self-correct.
System Errors
If the system senses a problem with theleft or right sensor, the telltale willilluminate and a message will appear inthe information display. See InformationMessages (page 102).
