SYSTEM
FUNCTION DESCRIPTION
• Lane Departure Warning (LDW) system provides a
lane departure warning function when the vehicle is
driven at speeds of approximately 70 km/h (45 MPH) or more.
• When the vehicle approaches either the left or the ri ght side of the traveling lane, a warning will sound and
the lane departure warning lamp (orange) on the combination meter will blink to alert the driver.
• The warning does not occur during turn signal operation (Lane change side).
• The warning function will stop when the vehicle returns inside of the lane markers.
EXAMPLE
When the vehicle approaches the right lane marker, the driv er is alerted by the buzzer and the blinking of lane
departure warning lamp (orange).
OPERATION DESCRIPTION
• When the system is turned ON by operating the warning systems switch, ITS control unit turns ON the warn-
ing systems ON indicator.
• Rear view camera monitors lane markers of the trav eling lane. It transmits the detected lane condition signal
to ITS control unit via ITS communication.
• When judging from a lane marker detection signal that the vehicle is approaching the lane marker, the ITS
control unit controls the following item to alert the driver.
- Activates warning buzzer
- ITS control unit transmits a lane departure warning lamp signal to combination meter via CAN communica- tion and turns ON/OFF the lane departure warning lamp (orange).
OPERATING CONDITION
• Warning systems ON indicator: ON
• Vehicle speed: approximately 70 km/h (45 MPH) or more
• Turn indicator signal: After 2 seconds or more from turned OFF
NOTE:
• When the LDW system setting on the vehicle information display is ON.
• After the operating conditions of warning are satisfi ed, the warning continues until the vehicle speed reaches
approximately 60 km/h (40 MPH)
• The LDW system may not function properly, depending on the situation. Refer to DAS-82, "Precautions for
Lane Departure Warning"
