Lane-keep Assist System

The lane-keep assist system alerts the driver that the vehicle may be deviating from its lane
and it provides steering assistance to help 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 travelling 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 4-196.
The steering wheel operation of the Lane-keep assist system has "Late" and "Early"
steering assist timing functions.
For the "Late" function, the system assists the driver's steering operation if there is the
possibility of the vehicle deviating from its lane.
For the "Early" function, the system assists the driver's steering operation constantly so
that the vehicle stays near the centre of the vehicle lane.
The "Late" and "Early" functions can be changed (timing at which steering assist is
provided) by changing the setting.
Refer to Personalisation Features on page 9-12.
