2023 Ford Expedition Owners Manual - What Is the Lane Keeping System



What Is the Lane Keeping System

The lane keeping system alerts you by providing temporary steering assistance or steering wheel vibration when it detects an unintended lane departure.

HOW DOES THE LANE KEEPING SYSTEM WORK



The lane keeping system uses a forward looking camera mounted on the windshield to monitor vehicle movement within the lane of travel.

When the camera detects a drift out of the lane of travel, the lane keeping system alerts the driver by vibrating the steering wheel, or aids the driver by providing a small steering input to move the vehicle back into the lane of travel.

The driver can select one of three modes:

  • Alert
  • Aid
  • Alert + Aid

LANE KEEPING SYSTEM PRECAUTIONS



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:  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:  In cold and severe weather conditions the system may not function. Rain, snow and spray can all limit sensor performance.
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.
WARNING   WARNING:  Large contrasts in outside lighting can limit sensor performance.
