Lane Departure Warning (LDW)
For vehicles with LDW, it is intended to help avoid unintentional lane departures. It may provide a warning if the vehicle is crossing a lane without using a turn signal. LDW uses a camera sensor to detect the lane markings. It only operates at speeds of 56 km (35 mph) or greater.
The LDW indicator, @, appears green if a lane marking is detected. It changes to amber, flashes, and sounds three chimes if the vehicle crosses a detected lane marking without using the turn signal.

To turn LDW on and off, press the LANE DEPART button, located on the steering wheel.
See Lane Departure Warning (LDW) on page 9‑48 for more information.
