Wiper Activated Headlamps
This feature activates the headlamps and parking lamps after the windshield wipers have been in use for about six seconds.
For this feature to work, the exterior lamp control must be in AUTO.
The wiper-activated headlamps immediately turn off, when the ignition is turned to LOCK/OFF or the windshield wiper control is turned off.
