2017 Ford F-150 Owners Manual - Lane Keeping System

Lane Keeping System

WARNING   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   WARNING:  Always drive with due care and attention when using and operating the controls and features on your vehicle.
WARNING   WARNING:  In cold and severe weather conditions the system may not function. Rain, snow and spray can all limit sensor performance.
WARNING   WARNING:  The system will not operate if the sensor cannot track the road lane markings.
WARNING   WARNING:  The sensor may incorrectly track lane markings as other structures or objects. This can result in a false or missed warning.
WARNING   WARNING:  The system may not operate properly if the sensor is blocked. Keep the windshield free from obstruction.
WARNING   WARNING:  If damage occurs in the immediate area surrounding the sensor, have your vehicle checked as soon as possible.
WARNING   WARNING:  The system may not correctly operate if your vehicle is fitted with a suspension kit not approved by us.

Note:   The system works as long as the camera can detect one lane marking.
Note:   When you select aid or alert and aid mode and the system detects no steering activity for a short period, the system alerts you to put your hands on the steering wheel. The system may detect a light grip or touch on the steering wheel as hands off driving.
Note:   The system works above 64 km/h.
Note:   The system may not function if the camera is blocked, or if the windshield is damaged or dirty.
Rear View Mirror Camera
When you switch the system on and it detects an unintentional drift out of your lane is likely to occur, the system notifies or assists you to stay in your lane through the steering system and information display. In Alert mode, the system provides a warning by vibrating the steering wheel. In Aid mode, the system provides steering assistance by gently counter steering your vehicle back into the lane.
When the system is functioning in the combined Alert and Aid mode, the system first provides steering assistance by gently counter steering your vehicle back into the lane, followed by a warning that vibrates the steering wheel if the vehicle is still out of the lane markings.
Switching the System On and Off
Note:   The system on or off setting is stored until it is manually changed, unless a MyKey™ is detected. If the system detects a MyKey™, it defaults to on and the mode is set to alert.
Note:   If a MyKey™ is detected, pressing the button does not affect the on or off status of the system.You can only change the mode and intensity settings.
Lane Keeping Assist Icon  Press the button on the center console to switch the system on or off.

System Display
Lane Keeping Aid Indicator  If you switch the system on in alert mode, a graphic with lane markings appears in the information display. Lane Keeping System Icon  If you switch the system on in aid or alert and aid mode, arrows appear with the lane markings.
When you switch the system off, the lane marking graphics do not display.
Note:   The overhead vehicle graphic may still be displayed if adaptive cruise control is enabled.
While the system is on, the color of the lane markings change to indicate the system status.
Gray: Indicates that the system is temporarily unable to provide a warning or intervention on the indicated side. This may be because:
  • Your vehicle is under the activation speed.
  • The direction indicator is active.
  • Your vehicle is in a dynamic maneuver.
  • Quick braking.
  • Fast acceleration.
  • The road has no or poor lane markings in the camera field-of-view.
  • The camera is obscured or unable to detect the lane markings due to environmental, traffic or vehicle conditions. For example, significant sun angles, shadows, snow, heavy rain or fog, following a large vehicle that is blocking or shadowing the lane or poor headlamp illumination.
See Troubleshooting for additional information.
Green: Indicates that the system is available or ready to provide a warning or intervention, on the indicated side.
Yellow: Indicates that the system is providing or has just provided a lane keeping aid intervention.
Red: Indicates that the system is providing or has just provided a lane keeping alert warning.
The system can be temporarily suppressed at any time by the following:
  • Quick braking.
  • Fast acceleration.
  • Using the direction indicator.
  • Evasive steering maneuver.
  • Driving too close to the lane markings.
