FUNCTION DESCRIPTION
• Lane Departure Warning (LDW) system provides a lane departure warning function when the vehicle is
driven at speeds of approximately 60 km/h (37 MPH) or more.
• When the vehicle approaches either the left or the right side of the traveling lane, a warning will sound and
LDW system display 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 driver is alerted by the buzzer and the blinking of LDW
system display.
OPERATION DESCRIPTION
• When the system is turned ON by operating the warning systems switch, front camera unit turns ON the
LDW ON indicator.
• Front camera unit monitors the traveling lane.
• When judging from a camera image signal that the vehicle is approaching the lane marker, front camera unit
controls the following item to alert the driver.
- Activates warning buzzer in the combination meter or transmits warning buzzer signal to sonar control unit.
- Front camera unit transmits a meter display signal to combination meter via CAN communication and turns
ON/OFF the LDW warning.
Operating Condition
• LDW ON indicator: ON
• Vehicle speed: approximately 60 km/h (37 MHP) or more
• Turn indicator signal: After 2 seconds or more from turned OFF
NOTE:
• When the LDW system setting on the combination meter is ON.
• After the operating conditions of warning are satisfied, the warning continues until the vehicle speed reaches
