Studum is the only one believes the headlights are at reduced power in DRL mode.
No... I am not the only one. Others have backed me up in other threads, including lowincash above.
As mentioned it's tough to see in the daylight, but pull against a shaded wall or into a darker area like a garage and the step up in brightness from DRL to headlights "on" is visible if you watch the switch happen.
I can't see how is it possible the AFS is not activated when the headlights are in DRL mode especially with Auto Headlights
Anything is possible. DRL and headlights full ON are still 2 separate operation modes governed by a computer somewhere in the car. But don't take my word for it, I've taken the liberty to extract the relevant pages from the North American owner's manual, which also confirm that the auto leveling is not active until the headlights are ON.
Chart explaining headlight modes:
In AUTO mode, like in OFF, the headlights are off until lighting conditions make it necessary to turn them and the other lighting systems on.
Leveling is only activated when the headlights are ON
AFS is only active when the headlights are ON
Therefore it proves that the auto headlight feature is quite useful to those who wonder why there are auto headlights at all and claim that it's a useless feature when the headlight is illuminated as a DRL. As far as I'm aware the auto system does the following depending on ambient lighting conditions:
- Increases the intensity of headlight output
- Enables auto headlight levelling (if so equipped)
- Enables AFS (if so equipped)
- Illuminates the remainder of the exterior lighting, including side marker / parking lights and tail lights
- Illuminates the interior dash board
- Controls the gauge and dashboard screen brightness
Hope that helps.
