Wally Posted April 18, 2009 Share Posted April 18, 2009 Does anyone know how to modify the auto-on headlights setting? I have an 08 IS250 SL & the manual says it can only be customised by the dealer. It comes as std set to a value of "3" but I've just come back from a recent 2 wks driving in all the rain & crappy dim conditions up north (of Sydney) & the lights were set to auto-on but never came on even when it was pouring rain so I want to adjust the setting down to "1" to make it ultra-sensitive. A silver car in rainy conditions on the highway is hard to see without lights on. Quote Link to comment Share on other sites More sharing options...
