LANE KEEPING SYSTEM (If Equipped)
WARNING: You are responsible forcontrolling your vehicle at all times. Thesystem is designed to be an aid and doesnot relieve you of your responsibility to drivewith due care and attention. Failure to followthis instruction could result in the loss ofcontrol of your vehicle, personal injury ordeath.
WARNING: Always drive with due careand attention when using and operating thecontrols and features on your vehicle.
WARNING: In cold and severe weatherconditions the system may not function. Rain,snow and spray can all limit sensorperformance.
WARNING: The system will not operateif the sensor cannot track the road lanemarkings.
WARNING: The sensor may incorrectlytrack lane markings as other structures orobjects. This can result in a false or missedwarning.
WARNING: Large contrasts in outsidelighting can limit sensor performance.
WARNING: The system may notoperate properly if the sensor is blocked.Keep the windshield free from obstruction.
WARNING: If damage occurs in theimmediate area surrounding the sensor, haveyour vehicle checked as soon as possible.
WARNING: The system may notcorrectly operate if your vehicle is fitted witha suspension kit not approved by us.
Note:The system works above 40 mph(64 km/h).
Note:The system works as long as thecamera can detect one lane marking.
Note:When aid mode is on and the systemdetects no steering activity for a short period,the system alerts you to put your hands onthe steering wheel. The system may detecta light grip or touch on the steering wheelas hands off driving.
Note:The system may not function if thecamera is blocked, or if the windshield isdamaged or dirty.

The system is designed to detect vehiclesthat may have entered the blind spot zone(A). The detection area is on both sides ofyour vehicle, extending rearward from theexterior mirrors to approximately 13 ft (4 m)beyond the rear bumper.
Note:The system does not prevent contactwith other vehicles. It is not designed todetect parked vehicles, pedestrians, animalsor other infrastructures.
Using the Blind Spot InformationSystem
Vehicles with Automatic Transmission
The system turns on when all of the followingoccur:
•You start your vehicle.
•You shift into drive (D).
•The vehicle speed is greater than 6 mph(10 km/h).
Note:The system does not operate in park(P) or reverse (R).
Vehicles with Manual Transmission
The system turns on when all of the followingoccur:
•You start your vehicle.
•The vehicle speed is greater than 6 mph(10 km/h).
Note:The system does not operate inreverse (R).
System Lights and Messages
When the system detects a vehicle, an alertindicator illuminates in the exterior mirror onthe side the approaching vehicle is comingfrom. If you turn the direction indicator on forthat side of your vehicle, the alert indicatorflashes.
Note:The system may not alert you if avehicle quickly passes through the detectionzone.
Blocked Sensors
The sensors are behind the rear bumper onboth sides of your vehicle.
Note:Keep the sensors free from snow, iceand large accumulations of dirt.
Note:Do not cover the sensors with bumperstickers, repair compound or other objects.

Note:Blocked sensors could affect systemperformance.
If the sensors are blocked, a message mayappear in the information display. SeeInformation Messages (page 116). The alertindicators remain illuminated but the systemdoes not alert you.
System Errors
If the system detects a fault, a warning lampilluminates and a message displays. SeeInformation Messages (page 116).
Switching the System Off and On
You can switch the system off using theinformation display. See GeneralInformation (page 110). When you switch thesystem off, a warning lamp illuminates anda message displays. When you switch thesystem on or off, the alert indicators flashtwice.
Note:The system remembers the last settingwhen you start your vehicle.
Note:The system may not correctly operatewhen towing a trailer. For vehicles with atrailer tow module and tow bar approved byus, the system turns off when you attach atrailer. For vehicles with an aftermarkettrailer tow module or tow bar, werecommend that you switch the system offwhen you attach a trailer.
To permanently switch the system off,contact an authorized dealer.
CROSS TRAFFIC ALERT (If Equipped)
WARNING: Do not use the cross trafficalert system as a replacement for using theinterior and exterior mirrors or looking overyour shoulder before reversing out of aparking space. The cross traffic alert systemis not a replacement for careful driving.
WARNING: The system may notoperate properly during severe weatherconditions, for example snow, ice, heavy rainand spray. Always drive with due care andattention. Failure to take care may result ina crash.
The system is designed to alert you ofvehicles approaching from the sides whenyou shift into reverse (R).
Using the Cross Traffic Alert System
The system is designed to detect vehiclesthat approach with a speed up to 37 mph(60 km/h). Coverage decreases when thesensors are partially, mostly or fullyobstructed. Slowly reversing helps increasethe coverage area and effectiveness.
The system turns on when you start theengine and you shift into reverse (R). Thesystem turns off when you shift out of reverse(R).

System Lights, Messages and AudibleAlerts
When the system detects a vehicle, anindicator illuminates in the exterior mirror onthe side the approaching vehicle is comingfrom. A tone sounds and a message appearsin the information display.
Note:In exceptional conditions, the systemcould alert you even when there is nothingin the detection zone, for example a vehiclepassing in the distance.
Blocked Sensors
The sensors are behind the rear bumper onboth sides of your vehicle.
Note:Keep the sensors free from snow, iceand large accumulations of dirt.
Note:Do not cover the sensors with bumperstickers, repair compound or other objects.
Note:Blocked sensors could affect systemperformance.
If the sensors are blocked, a message mayappear in the information display when youshift into reverse (R). See InformationMessages (page 116).
System Limitations
The system may not correctly operate whenany of the following occur:
•The sensors are blocked.
•Adjacently parked vehicles or objects areobstructing the sensors.
•Vehicles approach at speeds greaterthan 37 mph (60 km/h).
•The vehicle speed is greater than 7 mph(12 km/h).
•You reverse out of an angled parkingspace.
System Errors
If the system detects a fault a messagedisplays. See Information Messages (page116).
Switching the System Off and On
You can temporarily switch the system offusing the information display. SeeInformation Messages (page 116). When youswitch system off, a message displays. SeeInformation Messages (page 116).

Blocked SensorsIf a message regarding a blocked sensor orcamera appears in the information display,the radar signals or camera images areobstructed. The radar sensor is locatedbehind a fascia cover near the driver side ofthe lower grille. With an obstructed radar,the Pre-Collision Assist system does notfunction and cannot detect a vehicle ahead.With the front camera obstructed, thePre-Collision Assist system does not respondto pedestrians or stationary vehicles and thesystem performance on moving vehiclesreduces. The following table lists possiblecauses and actions for when this messagedisplays.

Note:If something hits the front end of yourvehicle or damage occurs, the radar sensingzone may change. This could cause missedor false vehicle detections. Contact anauthorized dealer to have the radar checkedfor proper coverage and operation.
Note:If your vehicle detects excessive heatat the camera or a potential misalignmentcondition, a message may display in theinformation display indicating temporarysensor unavailability. This messagedeactivates automatically when operationalconditions return to normal. For example,when the ambient temperature around thesensor decreases or the sensorautomatically recalibrates successfully.
DRIVE CONTROL (If Equipped)
Lincoln Drive Control
