Toyota Prius: LDA (Lane Departure Alert)

Basic functions

The LDA system warns the driver if the vehicle may deviate from the current lane or course*, and also can slightly operate the steering wheel to help avoid deviation from the lane or course*.

The front camera is used to detect lane lines or a course*.

*: Boundary between the asphalt and grass, soil, etc., or structures, such as a curb, guardrail, etc.

Lane departure alert function

The Lane Departure Alert function in the 2024 Toyota Prius activates when the system detects potential lane departure or deviation from the intended course. It prompts a visual warning on the display screen, accompanied by either a buzzer sounding or slight vibrations in the steering wheel to alert the driver. It is advised to visually check the surroundings and adjust the steering to guide the vehicle back towards the center of the lane or intended course. In vehicles equipped with Blind Spot Monitoring (BSM), the Lane Departure Alert may activate independently of turn signal usage if a potential collision with a vehicle in the adjacent lane is detected. This integrated safety feature enhances driver awareness and helps prevent unintended lane departures and potential collisions.

When the system determines that the vehicle might depart from its lane or course*, a warning is displayed on a display, and either a warning buzzer will sound or the steering wheel will vibrate to alert the driver.

Check the area around your vehicle and carefully operate the steering wheel to move the vehicle back to the center of the lane or course*.

Vehicles with BSM: If the system determines that the vehicle may collide with a vehicle in an adjacent lane, the lane departure alert will operate even if the turn signals are operating.

*: Boundary between the asphalt and grass, soil, etc., or structures, such as a curb, guardrail, etc.

Lane departure prevention function

If the system determines that the vehicle is likely to depart from its lane or course*, it provides assistance through steering wheel operations to help avoid deviation from the lane or course.

If the system determines that the steering wheel has not been operated for a certain amount of time or the steering wheel is not being firmly gripped, a warning message may be displayed and a warning buzzer may sound to alert the driver.

Vehicles with BSM: If the system determines that the vehicle may collide with a vehicle in an adjacent lane, the lane departure prevention function will operate even if the turn signals are operating.

*: Boundary between the asphalt and grass, soil, etc., or structures, such as a curb, guardrail, etc.

WARNING

Before using the LDA system

  • Do not overly rely on the LDA system. The LDA system is not a system which provides automated assistance in driving and it is not a system which reduces the amount of attention necessary for safe driving. The driver is solely responsible for paying attention to their surroundings and operating the steering wheel as necessary to ensure safety. Also, the driver is responsible for taking adequate breaks when fatigued, such as when driving for a long time.
  • Failure to perform appropriate driving operations and pay careful attention may lead to an accident.

Operating conditions of each function

  • Operating conditions of each function

This function is operable when all of the following conditions are met:

  • The vehicle speed is approximately 30 mph (50 km/h) or more.

Operation may be possible when the vehicle speed is approximately 25 mph (40 km/h) or more if vehicles, motorcycles, bicycles, or pedestrians are detected near the lane.

  • The system recognizes a lane or course*. (When recognized on only one side, the system will operate only for the recognized side.)
  • The lane width is approximately 9.8 ft. (3 m) or more.
  • The turn signal lever is not being operated.

(Vehicles with BSM: Except when a vehicle is detected in the direction that the turn signal lever is operated.)

  • The vehicle is not being driven around a sharp curve.
  • The vehicle is not accelerating or decelerating more than a certain amount.
  • The steering wheel is not being turned sufficiently to perform a lane change.

Temporary cancellation of functions

When the operational conditions are no longer met, a function on the Toyota Prius may be temporarily canceled. However, once the conditions for operation are met again, the function will automatically resume.

Operation of the lane departure alert function/lane departure prevention function

  • Depending on the vehicle speed, road conditions, lane departure angle, etc., operation of the lane departure prevention function may not be felt or the function may not operate.
  • Depending on the conditions, the warning buzzer may operate even if vibration is selected through a customize setting.
  • If a course* is not clear or straight, the lane departure alert function or lane departure prevention function may not operate.
  • The lane departure alert function or lane departure prevention function may not operate if the system judges that the vehicle is intentionally being steered to avoid a pedestrian or parked vehicle.
  • Vehicles with BSM: It may not be possible for the system to judge if there is danger of a collision with a vehicle in an adjacent lane.
  • The steering assist operation of the lane departure prevention function can be overridden by the steering wheel operation of the driver.

*: Boundary between the asphalt and grass, soil, etc., or structures, such as a curb, guardrail, etc.
