2019 LINCOLN NAVIGATOR traction control

When you shift to reverse (R), the sidesensing system provides audible warningswhen your vehicle is moving and obstaclesare detected within 24 in (60 cm) and areinside the driving path of your vehicle. Whenyou stop your vehicle the audible warningstops after two seconds.
Note:Visual distance indication remains onwhen the transmission is in reverse (R).
When you shift to drive (D) or any otherforward gear, for example, low (L), sport (S)or any forward gear in manual transmission,the side sensing system provides audibleand visual distance warnings when yourvehicle is moving below a speed of 5 mph(8 km/h) and obstacles are detected within24 in (60 cm) and are inside the driving pathof your vehicle. Once your vehicle reachesa standstill condition, the audible warningstops after two seconds and visual indicationstops after four seconds.
If the transmission is in neutral (N), the sidesensing system provides visual distanceindication only when your vehicle is movingbelow a speed of 5 mph (8 km/h) and thereis a front or rear parking aid obstacledetected, and the side obstacle is within24 in (60 cm) from the side of your vehicle.When you stop your vehicle the visualdistance indication stops after four seconds.
If the side sensing system is not available,the side distance indicator blocks do notappear.
The side sensing system is not availableunder the following condition:
•If you switch the traction control systemoff.
The side sensing system may not beavailable until you have driven approximatelythe length of your vehicle in order for thesystem to reinitialize if:
•You switch the ignition on, off and backon.
•Your vehicle remains stationary for overtwo minutes.
•The anti-lock brake system is activated.
•The traction control system is activated.
•When the steering wheel angleinformation is not available, the sidesensing system is not available. Thevehicle must be driven at least 492 ft(150 m) above 19 mph (30 km/h) torecover the steering wheel angleinformation.

Note:If you drive your vehicle less than 2 ft(0.5 m) or greater than 5 ft (1.5 m) away fromother parked vehicles, the system may notbe able to detect an available parkingspace.
When the system detects a suitable space,a message displays and a tone sounds. Stopyour vehicle and follow the onscreeninstructions. If your vehicle is moving veryslowly, you may have to move forward ashort distance before the system is ready topark.
Note:You must observe that the space thesystem selects remains clear of obstructionsat all times during the maneuver.
Note:The system always offers the lastparking space it detects. For example, if yourvehicle detects multiple spaces when youare driving, it offers the last one.
Note:If the vehicle speed is greater thanapproximately 22 mph (35 km/h), the systemshows a message to instruct you to reducethe vehicle speed.
Automatically Steering into a ParallelParking Space
When you shift into reverse (R), with yourhands off the steering wheel and nothingobstructing its movement, your vehicle steersitself into the space. The system displaysinstructions to move your vehicle backwardand forward in the space.
Note:If the vehicle speed exceedsapproximately 6 mph (9 km/h), you interruptthe maneuver, or the system switches off,you must take full control of your vehicle.
Note:If the system detects an object is veryclose to your vehicle and it may be unsafeto continue the maneuver, it may instruct youto stop your vehicle. The system may notprovide any further instruction. Steeringassistance continues to operate but youmust decide if it is safe to continue themaneuver.
When you believe your vehicle is correctlyparked, or a solid tone sounds and aninformation message appears, bring yourvehicle to a complete stop.
When the Active Park Assist maneuver iscomplete, a tone sounds and an informationmessage appears.

•The traction control system activates orfails.
•The anti-lock brake system activates orfails.
If the system malfunctions, a messageappears and a tone sounds. Have yourvehicle checked as soon as possible.
Perpendicular Parking
The system detects available perpendicularparking spaces and steers your vehicle intothe space. You control the accelerator,gearshift and brakes. The system visuallyand audibly guides you into a perpendicularparking space.
Press the button twice to searchfor a parking space.
When the vehicle speed is less than 19 mph(30 km/h), the system scans both sides ofyour vehicle for an available parking space.A message and a graphic appear in theinformation display to indicate the system issearching for a parking space. Use thedirection indicator lever to search for aparking space on the driver or passengerside of your vehicle.
Note:The system scans both sides of yourvehicle and offers parking spaces one sideat a time if you do not use the directionindicator.
Note:The system defaults to the passengerside if you do not use the direction indicator.
Drive your vehicle approximately 3 ft (1 m)and perpendicular to the other parkedvehicles when searching for a parking space.
Note:If you drive your vehicle less than 2 ft(0.5 m) or greater than 5 ft (1.5 m) away fromother parked vehicles, the system may notbe able to detect an available parkingspace.
When the system detects a suitable space,a message displays and a tone sounds. Stopyour vehicle and follow the onscreeninstructions. If your vehicle is moving veryslowly, you may have to move forward ashort distance before the system is ready topark.
Note:You must observe that the space thesystem selects remains clear of obstructionsat all times during the maneuver.

Troubleshooting
Possible CauseSymptom
You may have switched the traction control off.The system does not search for a parking space.
The transmission is in reverse (R). Your vehicle must be moving forward to be able todetect a parking space.
The sensors may be blocked. For example, snow, ice or dirt buildup. Blocked sensorscan affect how the system functions.The system does not offer a parking space.
There is not enough room in the parking space for your vehicle to safely park.
There is not enough space for the parking maneuver on the opposite side of the parkingspace.
The parking space is more than 5 ft (1.5 m) or less than 2 ft (0.5 m) away.
The vehicle speed is greater than 22 mph (35 km/h) for parallel parking or greater than19 mph (30 km/h) for perpendicular parking.
You recently disconnected or replaced the battery. After you reconnect the battery youmust drive your vehicle on a straight road for a short period of time.
Your vehicle is rolling in the opposite direction of the current transmission position. Forexample, rolling forward when in reverse (R).The system does not correctly position your vehiclein a parking space.
An irregular curb along the parking space prevents the system from correctly aligningyour vehicle.
