*Some models.
Lane-keep Assist System (LAS) & Lane Departure
Warning System (LDWS)*
The Lane-keep Assist System (LAS) & Lane Departure Warning System (LDWS) alerts the
driver that the vehicle may be deviating from its lane and it provides s\
teering assistance to
help the driver stay within the vehicle lanes.
The Forward Sensing Camera (FSC) detects the white lines (yellow line\
s) of the vehicle
lane in which the vehicle is traveling and if the system determines that\
the vehicle may
deviate from its lane, it operates the electric power steering to assist\
the driver's steering
operation. The system also alerts the driver by activating a lane departure warning\
sound,
vibrating the steering wheel, and indicating an alert in the display.
Refer to Forward Sensing Camera (FSC) on page
