How it works
Set your vehicle’s light switch to AUTO. Your fog lights turn on automatically at night and turn off during the day.
The pre-installed AFF adapter turns the fog lights off when you switch on your high beams, then turns them back on when you switch the high beams off at night in AUTO mode.

Choose your light-switch position and time of day below. The OFF and ON columns refer to the high-beam switch position; each row shows whether that light is on or off. All settings use the AFF adapter.
DRL = daytime running lights. DRL values apply to vehicles with factory LED DRLs, such as XSE and XLE models.
