2024 Lincoln Adaptive Cruise Control
HOW DOES ADAPTIVE CRUISE CONTROL WITH STOP-AND-GO WORK
Adaptive cruise control with stop-and-go uses radar and camera sensors to maintain a set gap between your vehicle and the vehicle in front of you while following it to a complete stop. Stop and go can also be set to follow a vehicle directly in front of you and adjust the set speed, while you are at a complete stop.
ADAPTIVE CRUISE CONTROL PRECAUTIONS
WARNING: You are responsible for controlling your vehicle at all times. The system is designed to be an aid and does not relieve you of your responsibility to drive with due care and attention. Failure to follow this instruction could result in the loss of control of your vehicle, personal injury or death.
WARNING: Do not use adaptive cruise control on winding roads, in heavy traffic or when the road surface is slippery. This could result in loss of vehicle control, serious injury or death.
WARNING: Pay close attention to changing road conditions such as entering or leaving a highway, on roads with intersections or roundabouts, roads without visible lanes of travel, roads that are unpaved, or steep slopes. Failure to follow this instruction could result in the loss of control of your vehicle, personal injury or death.
WARNING: The system is not a crash warning or avoidance system.
WARNING: Do not use the system when towing a trailer that has aftermarket electronic trailer brake controls. Failure to follow this instruction could result in the loss of control of your vehicle, personal injury or death.
WARNING: Do not use tire sizes other than those recommended because this can affect the normal operation of the system. Failure to do so may result in a loss of vehicle control, which could result in serious injury.
WARNING: Do not use the system with a snow plow blade installed.
WARNING: In situations with poor visibility, such as fog, heavy rain or other inclement weather, you may need to override or completely switch off the system.
When Following a Vehicle
WARNING: When following a vehicle that is braking, your vehicle does not always decelerate quickly enough to avoid a crash without driver intervention. Apply the brakes when necessary. Failure to follow this instruction could result in personal injury or death.
Hilly Condition Usage
Select a lower gear when the system is active in situations such as prolonged downhill driving on steep slopes, for example in mountainous areas.
ADAPTIVE CRUISE CONTROL LIMITATIONS
Sensor Limitations
WARNING: On rare occasions, detection issues can occur due to the road infrastructures, for example bridges, tunnels and safety barriers. In these cases, the system may brake late or unexpectedly. At all times, you are responsible for controlling your vehicle, supervising the system and intervening, if required.
WARNING: If the system malfunctions, have your vehicle checked as soon as possible.
WARNING: Large contrasts in outside lighting can limit sensor performance.
WARNING: The system only warns of vehicles detected by the radar sensor. In some cases there may be no warning or a delayed warning. Apply the brakes when necessary. Failure to follow this instruction could result in personal injury or death.
WARNING: The system may not detect stationary or slow moving vehicles below 6 mph (10 km/h).
WARNING: The system does not detect pedestrians or objects in the road.
WARNING: The system does not detect oncoming vehicles in the same lane.
WARNING: The system may not operate properly if the sensor is blocked. Keep the windshield free from obstruction.
WARNING: The sensor may incorrectly track lane markings as other structures or objects. This can result in a false or missed warning.
- Camera.
- Radar sensor.
The camera is on the windshield behind the
interior mirror. The radar sensor is in the lower grille.
Note: You cannot see the sensor. It is behind a fascia panel.
Note: Keep the front of your vehicle free of dirt, metal badges or objects. Vehicle front protectors, aftermarket lights, additional paint or plastic coatings could also degrade sensor performance.
A message displays if something obstructs the camera or the sensor. When something blocks the sensor, the system cannot detect a vehicle ahead and does not function. The radar sensor has a limited field of view. It may not detect vehicles at all or detect a vehicle later than expected in some situations. The lead vehicle image does not illuminate if the system does not detect a vehicle in front of you.
Detection Issues Can Occur:
- When driving on a different line than the vehicle in front.
- With vehicles that edge into your lane. The system can only detect these vehicles once they move fully into your lane.
- There may be issues with the detection of vehicles in front when driving into and coming out of a bend or curve in the road.
In these cases, the system may brake late or unexpectedly. If something hits the front end of your vehicle or damage occurs, the radar-sensing zone may change. This could cause missed or false vehicle detection. Optimal system performance requires a clear view of the road by the windshield camera.
Optimal performance may not occur if:
- The camera is blocked.
- There is poor visibility or lighting conditions.
- There are bad weather conditions.
SWITCHING ADAPTIVE CRUISE CONTROL ON AND OFF
The cruise controls are on the steering wheel.
Switching Adaptive Cruise Control On
Press the button to activate the system. When the system activates, the set speed is equal to whichever is greater, the current vehicle speed, or 15 mph when in imperial units or 20 km/h when in metric units. If the speed is too low, or other conditions are not correct for adaptive cruise control activation, the system enters standby mode. When you are below 15 mph when in imperial units or 20 km/h when in metric units, adaptive cruise control does not activate unless you are following another vehicle.
The indicator, current gap setting and set speed appear in the instrument cluster display.
Switching Adaptive Cruise Control Off
Press the button when the system is in standby mode or switch the ignition off.
Note: When you switch the system off, the set speed clears.
ADAPTIVE CRUISE CONTROL AUTOMATIC CANCELLATION
The system may cancel if:
- The tires lose traction.
- You apply the parking brake.
The system may cancel and set the parking brake if:
- You unbuckle the seatbelt and open the driver door after adaptive cruise control stops your vehicle.
- Adaptive cruise control holds your vehicle at a stop continuously for more than three minutes.
The system may deactivate or prevent activating when requested if:
- The vehicle has a blocked sensor.
- The brake temperature is too high.
- There is a failure in the system or a related system.
SETTING THE ADAPTIVE CRUISE CONTROL SPEED
WARNING: When you are going downhill, your vehicle speed could increase above the set speed. The system does not apply the brakes.
Drive to the speed you prefer.
Press either button to set the current speed.
Take your foot off the accelerator pedal. The indicator, current gap setting and set speed appear in the instrument cluster display when initially activating adaptive cruise control.
After a few seconds, the graphic in the instrument cluster display changes to show that adaptive cruise control is active.
A vehicle image illuminates if there is a vehicle detected in front of you.
Note: When adaptive cruise control is active, the speedometer can vary slightly from the set speed displayed in the instrument cluster display.
Setting the Adaptive Cruise Speed from a Complete Stop
Press the SET+ or SET- buttons while keeping the brake pedal fully depressed. The set speed adjusts to 20 km/h when in metric units or 15 mph when in imperial units. The indicator, current gap setting and set speed appear in the instrument cluster display.
Note: The system activates from a complete stop only when it detects a lead vehicle in close proximity.
Manually Changing the Set Speed
Press the button to increase the set speed in small increments. Press and hold the button to increase the set speed in large increments. Release the button when the set speed is equal to the desired speed.
Press the button to decrease the set speed in small increments. Press and hold the button to decrease the set speed in large increments. Release the button when the set speed is equal to the desired speed. You can also press the accelerator or brake pedal until you reach the speed you prefer. Press either button to select the current speed as the set speed. The system could apply the brakes to slow the vehicle to the new set speed. The set speed continuously displays in the instrument cluster display when the system is active.
SETTING THE ADAPTIVE CRUISE CONTROL GAP
You can decrease or increase the distance between your vehicle and the vehicle in front by pressing the gap control.
Press button to increase the gap setting.
Press the button to decrease the gap setting.
The selected gap appears in the instrument cluster display as shown by the bars in the image.
Note: The gap setting is time dependent and therefore, the distance adjusts with your vehicle speed.
Note: It is your responsibility to select a gap appropriate to the driving conditions.
Adaptive Cruise Control Gap Settings
Each time you switch the system on, it selects the last chosen gap setting.
Following a Vehicle
When a vehicle ahead of you enters the same lane or a slower vehicle is ahead in the same lane, the vehicle speed adjusts to maintain the gap setting.
Note: When you are following a vehicle and you switch on a turn signal lamp, adaptive cruise control may provide a small, temporary acceleration to help you pass.
Your vehicle maintains a consistent gap from the vehicle ahead until:
- The vehicle in front of you accelerates to a speed above the set speed.
- The vehicle in front of you moves out of the lane you are in.
- You set a new gap distance.
The system applies the brakes to slow down your vehicle to maintain a safe gap distance from the vehicle in front of you. The system only applies limited braking. You can override the system by applying the brakes.
Note: The brakes may emit noise when applied by the system.
If the system determines that its maximum braking level is not sufficient, an audible warning sounds, a message appears in the instrument cluster display and an indicator flashes when the system continues to brake. Take immediate action.
CANCELING THE SET SPEED
Press the button or tap the brake pedal. The set speed does not erase.
RESUMING THE SET SPEED
Press the button. The vehicle speed returns to the previously set speed and gap setting. The set speed displays continuously in the instrument cluster display when the system is active.
Note: Only use resume if you are aware of\ the set speed and intend to return to it.
Resuming the Set Speed from a Complete Stop (If Equipped)
If your vehicle follows a vehicle to a complete stop and remains stationary for less than a few seconds, your vehicle accelerates from a stationary position to follow the vehicle ahead. If your vehicle follows a vehicle to a complete stop and remains stationary for more than a few seconds, an indicator and message displays.
OVERRIDING THE SET SPEED
WARNING: If you override the system by pressing the accelerator pedal, it does not automatically apply the brakes to maintain a gap from any vehicle ahead.
When you press the accelerator pedal, you override the set speed and gap distance. Use the accelerator pedal to intentionally exceed the set speed limit. When you override the system, the set speed icon changes to gray and the leading vehicle icon does not appear in the instrument cluster display. The system resumes operation when you release the accelerator pedal. The vehicle speed decreases to the set speed, or a lower speed if following a slower vehicle.
ADAPTIVE CRUISE CONTROL INDICATORS
Illuminates when you switch adaptive cruise control on. The color of the indicator changes to indicate the system status. White indicates the system is on but inactive. Blue indicates that you set the speed and the system is active.
SWITCHING FROM ADAPTIVE CRUISE CONTROL TO CRUISE CONTROL
WARNING: Normal cruise control will not brake when your vehicle is approaching slower vehicles. Always be aware of which mode you have selected and apply the brakes when necessary.
- From the settings menu, press Driver Assistance.
- Press Cruise Control.
- Press Normal Cruise Control.
The cruise control indicator replaces the adaptive cruise control indicator if you select normal cruise control. The gap setting does not display, and the system does not respond to lead vehicles. Automatic braking remains active to maintain set speed. The system remembers the last setting when you start your vehicle.
LANE CENTERING
HOW DOES LANE CENTERING WORK
Adaptive cruise control with lane centering uses the vehicle’s front radar sensor and front windshield camera sensor, together with the steering sensor to operate. Using these sensors, the system applies continuous steering assistance towards driving in the middle of the lane you choose on highway roads.
Note: The gap setting for adaptive cruise control with lane centering, operates in the same way as normal adaptive cruise control.
LANE CENTERING PRECAUTIONS
WARNING: Do not use the system when towing a trailer or when the vehicle is loaded to near or over maximum payload. Failure to follow this instruction could result in the loss of control of your vehicle, personal injury or death.
WARNING: Do not use the system if any changes or modifications to the steering, suspension system or wheels and tires have been made. Any changes or modifications to the steering, suspension system or wheels and tires could affect the functionality and performance of the system. Failure to follow this instruction could result in the loss of control of your vehicle, personal injury or death.
Adaptive cruise control precautions apply to lane centering unless stated otherwise or contradicted by a lane centering precaution.
LANE CENTERING REQUIREMENTS
You must keep your hands on the steering wheel at all times.
Lane centring only activates when all of the following occur:
- Adaptive cruise control with lane centering is enabled in the touchscreen.
- You have adaptive cruise control with stop and go enabled and set.
- The steering sensor detects your hands on the steering wheel.
- The system detects both lane markings when driving on a straight road.
- Your vehicle is initially centred in the lane between two visible line markings.
Note: If the system does not detect valid lane line markings, the system remains in standby until valid line markings are available.
Note: If the system does not detect your hands on the steering wheel, apply a slight force to the steering wheel.
LANE CENTERING LIMITATIONS
Adaptive cruise control limitations apply to lane centering unless stated otherwise or contradicted by a lane centering limitation.
Lane centering may not correctly operate in any of the following conditions:
- The lane width is too narrow or wide.
- The curve in the road is too sharp.
- The system does not detect the minimum required lane markings or when lanes merge or split.
- When the required steering effort to maintain lane center exceeds the lane centering system limit.
- When driving in areas that are under construction or when road work is in progress.
- If the front windshield camera and/or the front radar are blocked.
- When using a spare tire.
- Inclement weather conditions including, but not limited to, high wind, heavy rain, and fog.
- Driving into direct sunlight and/or low light conditions.
- When modification to the steering system has been made, including alterations to the steering wheel.
- When towing a trailer.
- When the vehicle is loaded to near or maximum payload.
Note: System operation may also be limited under snow, heavy rain, or road spray conditions.
Note: The system’s steering assistance is limited and may not have sufficient effort for all driving situations and/or conditions, such as driving through sharp curves or driving through curves at high speeds.
SWITCHING LANE CENTERING ON AND OFF
You must keep your hands on the steering wheel at all times. The controls are on the steering wheel.
Press the button. The indicator appears in the instrument cluster. When the lane centering system is on, the color of the indicator changes to indicate the system status. You can override the system at any time by steering your vehicle.

Enabling and Disabling Lane Centering
- From the settings menu, press Driver Assistance.
- Press Cruise Control.
- Press Adaptive Cruise Control.
- Switch Lane Centering on or off.
LANE CENTERING ALERTS
You must keep your hands on the steering wheel at all times. When the system is active and detects no steering activity for a period of time, the system alerts you to put your hands on the steering wheel. If you do not react appropriately to the warnings the adaptive cruise control with lane centering system cancels and slows your vehicle down to idle speeds while maintaining steering control. The system also alerts you if your vehicle crosses lane line markings without detected steering activity.
Note: For keep hands on the wheel alert, the system may not detect a light grip or touch on the steering wheel. A slight steering wheel input may be required to cancel the message.
LANE CENTERING AUTOMATIC CANCELLATION
When an external condition cancels the system, and your hands are on the steering wheel, a tone sounds and a message appears in the instrument cluster display. When an external condition cancels the system, and your hands are not on the steering wheel, the system immediately alerts you to take control of the vehicle. If this alert is ignored, the system slows the vehicle while maintaining steering assistance when lane markings are available. When no lane markings are available, the vehicle comes to a stop.
If your vehicle starts to slow down after system cancellation, you must take full control of the vehicle. To re-enable adaptive cruise control with lane centering after cancellation, press and release the resume button.
Automatic cancellation can also occur if:
- The lane becomes too wide or narrow.
- The system cannot detect valid lane markings.
- Lane markings cross over one another.
- The curve of the road is too sharp.
Note: If your vehicle slows down due to your inactivity twice within a key cycle, the system disables. To reset the system, when the vehicle is stationary, return the gear selector to park (P) and turn the vehicle off. Then, restart the vehicle with your foot on the brake pedal.
LANE CENTERING MANUAL CANCELLATION
When you perform the following actions, adaptive cruise control with lane centering will cancel:
- The brake pedal is pressed.
- Adaptive cruise control button on the steering wheel is switched off.
The lane centering system is momentarily suppressed when either of the following actions are performed:
- Turn signal indicator is latched or tapped.
- You steer the vehicle out of lane.
LANE CENTERING INDICATORS
Illuminates when you switch lane centering on. The color of the indicator changes to indicate the system status. Gray status indicates the system is on but in standby mode. Green status indicates the system is enabled and applying steering assistance to keep the vehicle in the center of the lane. Amber status with an audible tone, that then changes to gray status, indicates a system automatic cancellation.

Note: Depending on your vehicle options and instrument cluster type, some messages can appear different or not at all.
PREDICTIVE SPEED ASSIST
HOW DOES PREDICTIVE SPEED ASSIST WORK
Predictive Speed Assist works with adaptive cruise control and adjusts the vehicle speed to the road geometry and to the speed limit detected by the speed sign recognition system. As the system identifies curves and highway exits, the vehicle speed temporarily decreases ahead of and during the changing road geometry. When passing new speed signs, the set speed updates. There are limitations that affect the accuracy of the speed sign recognition system and its ability to determine the current speed limit. Predictive speed assist and its ability to determine the current speed limit shares these limitations.
Note: The adaptive cruise control gap setting operates normally when the feature is enabled.
PREDICTIVE SPEED ASSIST PRECAUTIONS
WARNING: You are responsible for controlling your vehicle at all times. The system is designed to be an aid and does not relieve you of your responsibility to drive with due care and attention. Failure to follow this instruction could result in the loss of control of your vehicle, personal injury or death.
WARNING: Pay close attention to changing road conditions. You may need to override the system by pressing the brake or accelerator pedal if the adjusted speed becomes higher or lower than necessary.
WARNING: The system only provides limited braking. Your vehicle may not always decelerate quickly enough to avoid a crash without driver intervention. Apply the brakes when necessary.
WARNING: The system does not activate the turn signal.
Adaptive cruise control precautions apply to predictive speed assist unless stated otherwise or contradicted by a predictive speed assist precaution. The system only applies limited braking. You can override the system with the accelerator pedal or cancel the system by applying the brakes. The system may adapt to various factors such as time of day, lane width. This could influence speed adjustments and accelerations. The system may adapt to various drive modes. This could influence speed adjustments and accelerations.
Note: The system does not activate the turn signal automatically.
PREDICTIVE SPEED ASSIST LIMITATIONS
WARNING: The system may not always adjust vehicle speed in certain road or weather conditions such as crossing traffic, yield or stop signs, right of way, traffic lights, speed bumps, rain, snow, fog. You must always apply the brake or accelerator pedal when necessary.
The road geometry and speed limit information provided by the navigation map data could be inaccurate or out of date. The system may not detect and read speed limit signs with conditional information, for example, when a sign is flashing, during specific time ranges, or when children are present.
Note: The system does not set the vehicle speed to speed limits shown with a supplementary traffic sign.
Under certain conditions, the system may not adjust the vehicle speed until after your vehicle passes the speed limit. Detection of road geometry operates only where related information is available. Road geometry information may not be available in some areas.
