Lane Departure Warning (LDW)/Prevention (LDP) system (if so equipped)

Lane Departure Warning (LDW)/Prevention (LDP) system (if so equipped)  - Starting and driving - Infiniti QX Owners Manual - Infiniti QX

The Lane Departure Warning (LDW) system/ Lane Departure Prevention (LDP) system will operate when the vehicle is driven at speeds of approximately 45 MPH (70 km/h) and above, and when it is traveling close to either the left or the right of a traveling lane. Each system functions as follows:
► Lane Departure Warning (LDW) system Ч warns the driver by a warning light and chime.
► Lane Departure Prevention (LDP) system Ч warns the driver by a warning light and chime, and helps assist the driver to return the vehicle to the center direction of the traveling lane by applying brake control to the left or right wheels individually (for a short period of time).

The LDW and LDP systems monitor the lane

The LDW and LDP systems monitor the lane markers on the traveling lane using the camera unit 1 located inside the front map light cover. When the camera unit detects that the vehicle is traveling close to either the left or the right of the traveling lane, the lane departure warning light on the instrument panel blinks in orange and a warning chime sounds. When the LDP system is on, it will automatically apply the brakes for a short period of time, using the function of the Vehicle Dynamic Control (VDC) system.
