camera sensor on the upper portion
of the windshield.
Functions included in LDA system
Lane departure alert function

responsibility for driving safely by always 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.
