Yes you can just turn on the headlights manually if you don’t want to use the auto setting. You’ll still have the daytime running lights though, which are almost bright enough to drive at night with.
There’s a few minutes in the morning and afternoon I’ll sometimes turn them off auto, so they won’t be coming on and off when I drive through the shade. The off on flashing then probably annoys someone ahead of you.
Auto headlight setting can be disabled by turning the headlight dial off of auto, obviously. To disable the dash lights from automatically dimming when the headlights come on use the vertical dial next to the headlight dial.
