LDA (Lane Departure Alert with steering control)
While driving on a highway or freeway that has white (or yellow) lane markers
and few curves, a camera, which is located on the upper part of the windshield,
uses this system to recognize the white (yellow) lane markers and when the
driver has deviated from the lane. If the system judges that the vehicle has devi-
ated from the current traffic lane, along with alerting the driver with a buzzer and
indications in the multi-information display, it will provide assistance by operating
the steering wheel to avoid further deviation from the marker lines.

◆Lane deviation alert function
When the system judges that the vehicle is deviating from the current traffic lane,
an alert buzzer sounds and it prompts cautions from the display screen of the
multi-information display.
When the alert buzzer sounds, please ch eck the surrounding road situation and
return near the center of the white (yello w) lane markers by safely operating the
steering wheel.
◆ Steering control function
If the system judges that the vehicle has de viated from the current traffic lane, it is
displayed in the multi-information displa y and steering force is supplied to the
steering wheel by the steering control, pr oviding required assistance in steering
wheel operation to avoid further deviation from the marker lines.
In order to prevent over relying on the system, when the system does not operate the
steering wheel and driving where hands are lightly supporting the steering wheel
continues, a warning message is displa yed on the multi-information display.
