Lane-keep Assist System (LAS) & Lane Departure
Warning System (LDWS)
*
The LAS & LDWS alerts the driver that the vehicle may be deviating from its lane and it
provides steering assistance to he lp the driver stay within the vehicle lanes.
The Forward Sensing Camera (FSC) detects the white lines (yellow lines) of the vehicle
lane in which the vehicle is tra veling 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. Use the system when you
drive the vehicle on roads with white (yellow) lines such as expressways and highways.
Refer to Forward Sensing Camera (FSC) on page 4-223.

Do not rely completely on the LAS & LDWS:
The LAS & LDWS is not an automatic driving system. In addition, the system is not designed
to compensate for a driver's lack of caution, and over-reliance on the system could lead to
an accident.
The detection ability of the LAS & LDWS is limited. Always stay on course using the steering
wheel and drive with care.
Do not use the LAS & LDWS in the following cases:
The system may not operate adequately accordin g to the actual driving conditions, resulting
in an accident.
