Lane Departure Warning (LDW)
If a malfunction occurs in the lane camera unit, AD AS control unit cancels control, and turns ON the lane
departure warning lamp in the combination meter.
Lane Departure Prevention (LDP)
If a malfunction occurs in the lane camera unit, ADAS control unit cancels control, sounds a beep, and turns
ON the lane departure warning lamp in the combination meter.
TEMPORARY DISABLED STATUS AT HIGH TEMPERATURE
Lane Departure Warning (LDW)
 If the vehicle is parked in direct sunlight under high temperature conditions, the system may be deactivated
automatically. And the lane departure warning lamp (yellow) in the combination meter will blinks.
 When interior temperature is reduced, the system wil l resume operation automatically and the lane depar-
ture warning lamp (yellow) in the combination meter will stop blinking.
