Function Description

Lane Departure Warning (LDW) system provides a lane departure warning function when the vehicle is driven at speeds of approximately 45 MPH (70 km/h) or more.
When the vehicle approaches either the left or the right 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.
