2018 LINCOLN MKZ sensor

If you are uncomfortable with the proximityto any vehicle or object, you may choose tooverride the system by grabbing the steeringwheel or by pressing the button.
Parallel Park Out Assist automatically steersyour vehicle out of a parallel parking space(hands-free) while you control theaccelerator, gearshift and brakes. The systemvisually and audibly guides you to entertraffic.
The system may not correctly operate in anyof the following conditions:
•You use a spare tire or a tire significantlyworn more than the other tires.
•One or more tires are improperly inflated.
•You try to park on a tight curve.
•Something passes between the frontbumper and the parking space. Forexample, a pedestrian or cyclist.
•The edge of the neighboring parkedvehicle is high off the ground. Forexample, a bus, tow truck or flatbedtruck.
•The weather conditions are poor. Forexample, during heavy rain, snow or fog.
Note: Keep the sensors on the bumper orfascia free from snow, ice and largeaccumulations of dirt. Covered sensors canaffect the system's accuracy. Do not cleanthe sensors with sharp objects.
Note:The sensors may not detect objectswith surfaces that absorb ultrasonic wavesor cause ultrasonic interference. Forexample, motorcycle exhaust, truck airbrakes or horns.
Note:Following a change in tire size, thesystem must recalibrate and operation maybe impaired for a short time.
Do not use the system if:
•You have attached a foreign object closeto the sensors on the front or rear of yourvehicle. For example, a bike rack ortrailer.
•You attach an overhanging object to theroof. For example, a surfboard.
•A foreign object damages or obstructsthe front or rear bumper or side sensors.
•The correct tire size is not in use on yourvehicle. For example, a mini-spare tire.
Using Active Park Assist - Parallel Parking
Press the Active Park Assist buttononce to search for a parallelparking space.
When driving at a speed less than 22 mph(35 km/h), the system automatically scansboth sides of your vehicle for an availableparking space. The system displays amessage and a corresponding graphic toindicate it is searching for a parking space.Use the direction indicator to selectsearching either to the left-hand side orright-hand side of your vehicle.
Note:If the direction indicators are not used,the system defaults to the passenger sideof your vehicle.

Troubleshooting the System
Possible CauseSymptom
You may have the traction control system switched off.
The system does not look for a space.The transmission is in reverse (R). Your vehicle must be moving forward to be able todetect a parking space.
The sensors may be covered. For example, snow, ice or dirt buildup. Covered 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 16 in (0.4 m) away.
Your 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 a battery disconnect, you mustdrive 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 position the vehicle correctly.An irregular curb along the parking space prevents the system from aligning your vehicleproperly.
