I have the base and I'm somewhat confused by how the lights work as well.
The manual states that when the "off" is selected on the stalk, all headlights are off but this isn't true. I notice when the engine is on, the DRL are lit.
So my question is, if I left the stalk on "off" and let the DRL turn itself on when the engine is on, do I not need to worry about it during the day? That way you don't need to worry about forgetting to switch them off. Is everything lit properly when the engine is on?
It does seem like the lights are turned off when the engine is off but if the lights are "on", the instrument panel is still lit so that would drain the battery as well.
