SYSTEM DESCRIPTION
LANE DEPARTURE ALERT SYSTEM DESCRIPTION
(a) The lane departure alert system is a system which uses the forward recognition camera to recognize and determine the lane and the position of the vehicle when the vehicle is being driven on highways and other roads with white (yellow) lines. Based on the situation, this system provides information and warnings for the driver.

CONTROL OF EACH FUNCTION
(a) Lane departure alert function:
(1) Sensitivity: "Standard (graphic display)"
A warning is output when a front wheel starts to cross a lane marker.
HINT:
When the deviation speed (lateral travel speed) is slow, the warning may be output after the front wheel crosses over the lane marker.
(2) Sensitivity: "High (graphic display)"
A warning is provided when a front wheel nears a lane marker.
HINT:
When the deviation speed (lateral travel speed) is slow, the warning may be provided when the front wheel starts to cross the lane marker.
(b) Vehicle sway warning:
(1) A warning is output when any of the following occurs:
