Lane Departure Warning (LDW) Light

For vehicles with the lane departure warning system, this light briefly comes on green, while starting the vehicle, to indicate that it is working.
If it does not, have the vehicle serviced by your dealer/retailer. If the system is working normally the indicator light will then go off.
This light also comes on green if the system detects a left or right lane marking. It flashes, changes to amber and three beeps sound if a detected lane marking is crossed without using a turn signal. For more information, see the Index in the Navigation Manual.
