9.8.1.1. LDW system operation
The LDW system provides a lane departure warning function when the vehicle is driven at speeds of approximately 60 km/h (37 MPH) and above, and the lane markings are clear.
When the vehicle approaches either the left or the right side of the travelling lane, the steering wheel will vibrate and the LDW indicator on the Vehicle Information Display will blink to alert the driver.
The warning function will stop when the vehicle returns inside of the lane markers.
