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"

FAIL-SAFE CONTROL BY DTC
If a malfunction occurs in the rear view camera, ITS control unit cancels control, and turns ON the lane depar-
ture warning lamp in the combination meter.
BSW/LDW TEMPORARY DISABLED STATUS
Under the following condition, the BSW and/or LDW system is turned off temporarily, the BSW light (white)
and /or LDW light (white) will blink, and either of the following messages will appear in the vehicle information
display:
• ”trunk is open”
• ”washer fluid is low”
When the above condition no longer exists, the BSW and /or LDW system will resume automatically.

Precautions for Lane Departure WarningINFOID:0000000009464727
REAR VIEW CAMERA HANDLING
The rear camera unit “1” for the LDW/BSW syst
ems is located above the rear license plate.
To keep the proper operation of the LDW systems and pr event a system malfunction, be sure to observe the
following:
• Always keep the camera lens clean. Be careful not to damage the nozzle of the automatic washer and
blower.
• Do not attach ”license plate accessories” that reflect light.
• Do not strike or damage the areas around the camera unit.
LANE DEPARTURE WARNING (LDW)
• LDW system is only a warning device to inform the dr iver of a potential unintended lane departure. It will not
steer the vehicle or prevent loss of cont rol. It is the driver’s responsibility to stay alert, drive safely, keep the
vehicle in the traveling lane, and be in control of the vehicle at all times.
• The camera unit may not detect properly under the following conditions:
- When towing a trailer.
- When strong light enters the camera unit. (For exampl e, direct sunlight or headlight from the rear.)
- When ambient light changes instantly. (For example, when the vehicle enters or exits a tunnel or passes
under a bridge.)
• Automatic washer and blower may not be able to secure detection capability when excessive dirt adheres on the camera lens.
• Excessive noise (e.g. audio system volume, open vehi cle window) will interfere with the chime sound, and it
may not be heard.
• The camera unit may not be able to detect properly under the following conditions:
- On roads where there are multiple parallel lane marker s; lane markers that are faded or not painted clearly;
yellow painted lane markers; non-standard lane markers; or lane markers covered with water, dirt or snow,
etc.
- On roads where the discontinued lane markers are still detectable.
- On roads where there are sharp curves.
- On roads where there are sharply c ontrasting objects, such as shadows, snow, water, wheel ruts, seams or
lines remaining after road repairs. (The LDW syst em could detect these items as lane markers.)
- On roads where the traveling lane merges or separates.
- When the vehicle's traveling direction does not align with the lane marker.
- When the road surface is very dark due to scarce ambient light or impaired tail lamp.
• When driving on a curved road, warning will be late on the outside of the curve due to the nature of the sys-
tem.
