Why would you not have coming\leaving home lights on???
And as said the sensitivity is to set how light or dark it is for the lights to switch auto on or off.
Well, three main reasons:
1. I do not want to show others how high is my car specification. I also do not have "Leon" & "FR"
badge on the back, I use very rare mirrors folding. Security reasons. Want to have as less possible identification as possible.
2. I do not need to keep light. I live in the city, on the street is enough light in the night.
3. I don't like the way how it works. When you switch off engine, your light goes off, DLR stays. Then when you lock, lights goes on again. ?!?? The same when entering car - after unlocking lights goes on, then off and finally stays DLR only or goes lights on again. It is a bit mess...
And what is the settings?
Medium is for medium light - perfect naming.

And other setting? Which is for more darker and more lighter conditions?
I thought the sensitivity was for high beam assist.
But then if it's there and you don't have that option then maybe not.
No, I do not have high beam assist.
