Lane Departure Warning System (LDWS)
Lane Departure Warning System (LDWS) *
The LDWS notifi es the driver that the vehicle may be deviating from its lane.
The system detects the white or yellow lines on the traffi c lane using the Forward Sensing
Camera (FSC). If it determines that the vehicle may be deviating from \
its lane, it notifi es
the driver by fl ashing the LDWS indicator light (green) and operating the LDWS warning\

sound.
Refer to Forward Sensing Camera on page 4-62 .
Use the LDWS when you drive the vehicle on roads with white or yellow li\
nes.
