The fact that you can have them turned on is in
the manual but it appears it is a dealer performed option. I do not know of anyone who has done this without the dealer.
I used to have this turned on myself but I did not like the fact that ALL of the lights were on 24/7 when driving. It never made sense to me that the actual headlamps were on along with all the running lights, etc. I would have thought for "daytime use" that the low voltage lights in the front along with the parking lights would be all that are on but alas, not the case. I had my dealer investigate and apparently, they are either on or off completely and at this time only a dealer has the software to reprogram the processor.
