LDA (Lane Depar ture Alert With Yaw Assist
Function)
When driving on a road with clear white (yellow) lane lines, this func-
tion alerts the driver when the vehicle might depart from its lane or
course* and provides assistance by applying a brake force to keep
the vehicle in its lane or course*.
The LDA system recognizes white
(yellow) lane lines or a course*
using the front camera. Addition-
ally, 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

Summary of functions
WARNING
Q Before using LDA system
O Do not rely solely upon the LDA system. The LDA system does not auto-
matically 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 surround-
ing 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.
O Failure to perform appropriate driving operations and pay careful attention
may lead to an accident, resulting in death or serious injury.
O When not using the LDA system, use the LDA switch to turn the system
off.
