Toyota Corolla: Using the driving support systems / LDA (Lane Departure Alert with steering control)

Toyota Corolla 2019-2022 Owners Manual / Driving / Using the driving support systems / LDA (Lane Departure Alert with steering control)

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

The LDA system recognizes white (yellow) lane lines or a course* using the front camera. Additionally, it detects preceding vehicles using the front camera and radar.

*: Boundary between asphalt and the side of the road, such as grass, soil, or a curb

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 adequate 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.
  • When not using the LDA system, use the LDA switch to turn the system off.

■Situations unsuitable for LDA system

In the following situations, use the LDA switch to turn the system off. Failure to do so may lead to an accident, resulting in death or serious injury.

  • Vehicle is driven on a road surface which is slippery due to rainy weather, fallen snow, freezing, etc.
  • Vehicle is driven on a snow-covered road.
  • White (yellow) lines are difficult to see due to rain, snow, fog, dust, etc.
