LDA (Lane Departure Alert With Yaw Assist

Function)^

Summary of functions

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

WARNING

■ Before using LDA system

●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.

●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.

vehicle may depart from its lane. Drive safely by always paying careful

attention to your surroundings and operate the steering wheel to correct the

path of the vehicle without relying solely on the functions.

● Vehicle is being driven around a sharp curve.

●Objects or patterns that could be mis-

taken for white (yellow) lines are pres-

ent on the side of the road (guardrails,

reflective poles, etc.).

● Vehicle is driven where the road
