2020 Lincoln MKZ Owners Manual -  Using adaptive cruise control

 Using adaptive cruise control

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 winding, slippery, unpaved, or steep slopes.    WARNING:  Do not use the system in poor visibility, for example fog, heavy rain, spray or snow.    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:  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 is not a crash warning or avoidance system.

 The system adjusts your vehicle speed to maintain the set gap between you and the vehicle in front of you in the same lane. You can select four gap settings.

The system uses a radar sensor which projects a beam directly in front of your vehicle.

The cruise controls are on the steering wheel.   See   What Is Cruise Control. 

SWITCHING ADAPTIVE CRUISE CONTROL ON

For vehicles without Speed Limiter, press and release the button.

For vehicles with Speed Limiter, press and release the button.

The indicator, current gap setting and set speed appear in the information display.

SETTING THE ADAPTIVE CRUISE SPEED

Drive to your preferred speed.

  Press and release the button.

Take your foot off the accelerator pedal.

The indicator, current gap setting and set speed appear in the information display.

A vehicle graphic appears in the information display if the system detects a vehicle in front of you.

Note:   When adaptive cruise control is active, the speedometer may vary slightly from the set speed displayed in the information display.

SETTING THE ADAPTIVE CRUISE SPEED WHEN YOUR VEHICLE IS STATIONARY

Follow a vehicle to a complete stop.

  Press while keeping the brake pedal fully pressed.

The set speed adjusts to 20 mph (30 km/h).

The indicator, current gap setting and set speed appear in the information display.

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.    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.

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 a preset gap distance. A vehicle graphic appears in the information display.

Note:   The brakes may emit noise when applied by the system.

Note:   When you are following a vehicle and you switch on a direction indicator, 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 your vehicle to maintain a safe gap distance from the vehicle in front. The system only applies limited braking. You can override the system by applying the brakes.

If the system determines that its maximum braking level is not sufficient, an audible warning sounds, a message appears in the information display and an indicator flashes when the system continues to brake. Take immediate action.

FOLLOWING A VEHICLE TO A COMPLETE STOP

If your vehicle follows a vehicle to a complete stop and remains stationary for less than three 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 three seconds, press to follow the vehicle ahead. Or press the accelerator pedal.

SETTING THE GAP DISTANCE

You can decrease or increase the distance between your vehicle and the vehicle in front by pressing the gap control.

Press and release to decrease the gap distance.

Press and release to increase the gap distance.

The selected gap appears in the information 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.

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 normally to intentionally exceed the set speed limit.

When you override the system, the vehicle graphic disappears from the information 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.

CHANGING THE SET SPEED

Press and release to increase the set speed in small increments.

Press and release to decrease the set speed in small increments.

Press and hold either button to change the set speed in large increments. Release the button when you reach your preferred speed.

 The system may apply the brakes to slow the vehicle to the new set speed. The set speed displays continuously in the information display when the system is active.

CANCELING THE SET SPEED

  Press and release the button or tap the brake pedal.

Note:   The system remembers the set speed.

RESUMING THE SET SPEED

  Press and release the button.

 Your vehicle speed returns to the previously set speed and gap setting. The set speed displays continuously in the information display when the system is active.

Note:   Only use resume if you are aware of the set speed and intend to return to it.

AUTOMATIC CANCELLATION

Automatic cancellation can also occur when:

• The tires lose traction.
• You apply the parking brake.

PARK BRAKE APPLICATION

Automatic parking brake application and cancellation occurs if:

• You unbuckle the seatbelt and open the door after you stop the vehicle.
• You hold the vehicle at a stop continuously for more than three minutes.

HILLY CONDITION USAGE

Select a lower gear when the system is active in situations such as prolonged downhill driving on steep grades, for example in mountainous areas. The system needs additional engine braking in these situations to reduce the load on the vehicle’s regular brake system to prevent it from overheating.

Note:   An audible alarm sounds and the system shuts down if it applies brakes for an extended period of time. This allows the brakes to cool. The system functions normally again after the brakes cool.

SWITCHING ADAPTIVE CRUISE CONTROL OFF

For vehicles without Speed Limiter, press and release the button when the system is in standby mode or switch the ignition off.

For vehicles with Speed Limiter, press and release the button when the system is in standby mode or switch the ignition off.

Note:   You erase the set speed when you switch the system off.

DETECTION ISSUES

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.

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 graphic does not display if the system does not detect a vehicle in front of you.

DETECTION ISSUES CAN OCCUR: AWhen driving on a different line than the vehicle in front. BWith vehicles that edge into your lane. The system can only detect these vehicles once they move fully into your lane. CThere 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. You should stay alert and take action when necessary.

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-mounted camera.

Optimal performance may not occur if:

• The camera is blocked.
• There is poor visibility or lighting conditions.
• There are bad weather conditions.

SYSTEM NOT AVAILABLE

Conditions that can cause the system to deactivate or prevent the system from activating when requested include:

• A blocked sensor.
• High brake temperature.
• A failure in the system or a related system.

BLOCKED SENSOR

 A message displays if something obstructs the radar signals from the sensor. The sensor is in the lower grille. The system cannot detect a vehicle ahead and does not function when something blocks the sensor.

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.

POSSIBLE CAUSES AND ACTIONS FOR THIS MESSAGE DISPLAYING:

Due to the nature of radar technology, it is possible to get a blockage warning with no actual block. This happens, for example, when driving in sparse rural or desert environments. A false blocked condition either self clears, or clears after you restart your vehicle.

SWITCHING TO NORMAL 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.

  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.

You can change from adaptive cruise control to normal cruise control through the information display.
