Wiper Activated Headlamps
This feature activates the headlamps and parking lamps after the windshield wipers are turned on and have completed eight wipe cycles within four minutes.
When the ignition is turned to LOCK/OFF, the wiper-activated headlamps immediately turn off. The wiper-activated headlamps also turn off if the windshield wipers are turned off.
