Toyota Camry Lane Departure Alert with steering control

    Toyota Camry Lane Departure Alert with Steering Assist uses an in-vehicle camera designed to detect visible white and yellow lane markers in front of the vehicle and the vehicle’s position on the road

    Summary of functions

    When driving on highways and freeways with white (yellow) lines, this function alerts the driver when the vehicle might depart from its lane and provides assistance by operating the steering wheel to keep the vehicle in its lane.

    The LDA system recognizes visible white (yellow) lines with the front camera on the upper portion of the front windshield.

    Functions included in LDA system

    Lane departure alert function

    When the system determines that the vehicle might depart from its lane, a warning is displayed on the multi-information display and the warning buzzer sounds to alert the driver.

    When the warning buzzer sounds, check the surrounding road situation and carefully operate the steering wheel to move the vehicle back to the center of the lane.

    Steering control function

    When the system determines that the vehicle might depart from its lane, the system provides assistance as necessary by operating the steering wheel in small amounts for a short period of time to keep the vehicle in its lane.

    If the system detects that the steering wheel has not been operated for a fixed amount of time or the steering wheel is not being firmly gripped, a warning is displayed on the multi-information display and the warning buzzer sounds.

    Vehicle sway warning function

    When the vehicle is swaying or appears as if it may depart from its lane multiple times, the warning buzzer sounds and a message is displayed on the multi-information display to alert the driver.

    WARNING

    • Before using LDA system
      Do not rely solely upon the LDA system. The LDA system does not automatically drive the vehicle or reduce the amount of attention that must be paid to the area in front of the vehicle. The driver must always assume full responsibility for driving safely by paying careful attention to the surrounding conditions and operating the steering wheel to correct the path of the vehicle. Also, the driver must take adeq uate breaks when fatigued, such as from driving for a long period of time.
      Failure to perform appropriate driving operations and pay careful attention may lead to an accident, resulting in death or serious injury.
    • To avoid operating LDA system by mistake
      When not using the LDA system, use the LDA switch to turn the system off.
